Check and Install Hardware Depending on your order, your NetScan unit may not require all the steps under this heading. If a step does not apply to your unit, simply go on to the next one. NetScan Rear Panel Verify Voltage Setting Based on your order, your NetScan system was set at the voltage indicated on the sticker (located on the rear of the unit, near the power switch). Verify that the voltage value indicated on the sticker matches the voltage of your intended AC power supply.
Install Signal Conditioning Card(s) Signal conditioning cards are pre-installed per customer order. However, if you need to install a signal conditioning card, or CSN/Relay card, perform the following steps. Repeat the steps for additional cards, and for placing cards into the optional CSN/Exp expansion chassis, if applicable. &$87,21 Ensure NetScan is powered down and not connected to any power source prior to installing or removing a card. Failure to do so could cause equipment damage.
Setup for Ethernet Operation Complete Hardware Setup for Ethernet Operation If you want to operate your NetScan unit independent of (not-connected to) the ethernet, refer to Chapter 7 for serial operation. If you ordered a expansion chassis (CSN/Exp), please refer to Chapter 7 for installation instructions. Note 1: The DB9 connection to NetScan’s CONFIG Port is required only during initial configuration.
If you observe a configuration error, perform an error status query (see E? in Appendix A). If you observe any other type of error condition, make note of the error and contact your service representative.
If you ordered ChartView Plus, you must enter the registration ID number as it appears on your ChartView Plus Registration Sheet. Otherwise, press Next and continue to follow the screen prompts. Screen Prompt for Entering the ChartView Plus ID Using the NetScan Configuration Utility NetScan must be configured before you can use it in the ethernet mode. Configuration is accomplished through the NetScan Configuration Utility that activates after you select “NetScan” as your device type.
NetScan Configuration Utility, Step 3 You will receive a “>>Communications Error<<” if the NetScan Configuration Utility fails to communicate with NetScan. Likely causes are: 1) Wrong COMM Port selected in the utility (step1). 2) Serial cable connected to wrong connector on NetScan, PC, or both. If you received the error message, check system cable connections, correct the problem, then return to Step 2 and perform the requested actions. Finished a) Exit the NetScan Configuration Utility.
NetScan and TCP/IP Addressing Protocol The NetScan uses TCP/IP (Transport Control Protocol/Internet Protocol) for communications over the ethernet. You can access NetScan devices from virtually anywhere in the world since the World Wide Web uses this same protocol. TCP/IP addressing consists of three parameters: the IP address, the Sub-net Mask, and the Gateway Address. Each of these parameters consists of four different numbers which range from 0 to 255.
Configuration There are four basic network scenarios that pertain to NetScan ethernet operation. Note that proper TCP/IP configuration is extremely important, and you must obtain TCP/IP addressing parameters before configuring the protocol. The rules for configuration differ for each scenario as follows: 1) Point-to-Point Setup Point-to-Point Setup In the Point-to-Point scenario, NetScan is connected directly to a PC using a crossover cable.
3) Private LAN Setup with Multiple Networks Private LAN with Multiple Networks In multiple-network scenarios, two or more networks connect to a common gateway via ethernet hubs. In regard to multiple networks, a qualified network administrator should assign all TCP/IP parameters. 4) LAN Setup with Internet Access LAN Setup with Gateway Access to Internet In internet access scenarios, a network adminstrator usually assigns TCP/IP parameters.
The following figure and table identify pin locations for outputs, inputs, and grounds associated with the DB50 connector.

Groups, Charts, & Channels When starting the program with no configuration file present (see Chapter 2 if necessary), a feature called Chart Setup Wizard is automatically activated to assist you with your display setup. To make the best use of Chart Setup Wizard you need to understand the relationship of Groups, Charts, and Channels. Group. “Group” refers to a group of charts. ChartView makes use of one chart group.
Some of the data acquisition scenarios pertaining to ChartView are as follows: 2) Acquiring & Uploading Acquisition 1) Waiting for Trigger H ar d D is k S e n sor B u ffe r B u ffe r Acquisiton Device Com puter S ystem Data is received by acqu isition device, but not stored. Selected cha nnels can be view ed graph ically in scrolling cha rts, as well as in one or m ore m e te rs (analo g, digital, or bar graph). Acquisiton Device Device has been triggered.
Main Window While using this chapter, refer to the Main Window figure and its associated control option table as needed. Because of the graphic aspect of the window, you should be able to develop a good understanding of the program’s capabilities and associated operating techniques within a very short time. The following comments apply to the figure and table on the following page.
ChartView Main Window and Control Options = Mouse, Ú= Arrow Keypads , = PageUp/PageDown Keypads 1 Group Select 2 Start Charts and Indicators 3 Pause Charts 4 Ú, or Note: The bulleted list on page 4-4 relates to this table.
Channel Information Region Channels can return values in units of °C, °F, °K, °R, mV, V, or user defined units (if the mX + b option is used). With exception of mX + b user defined-units, units depend on the configuration and type of signal conditioning card used. Signal conditioning cards are detailed in the user’s manual for you data acquisition device. The Channel Information Region is located on the right-hand side of ChartView’s main window.
Units/div - The units in units/div (18) can be °C, °F, °K, °R, mV, or V. The division referenced is one vertical grid. In the example above for Channel 1, each vertical grid increment represents 10.58°C per division. Changing the units/division spinner controls (σ/τ) will result in an automatic adjustment of the max scale and min scale values (items 13 and 19).
Main Window Toolbar Each item in the toolbar, with exception of Group Select (1), is represented by an individual button icon. Toolbar-related functions can also be activated from pull-down menus (discussed later). Placing the cursor on the button and clicking the mouse button enables the tool, or opens a corresponding dialog box. Each Toolbar button has a pop-up label that appears when the mouse is placed over the button. Note: The toolbar represented below is for ChartView’s Main Window.
Display Configuration The Display Configuration button accesses a Display Configuration Setup dialog box. This box will also be displayed if: a) Create Charts Manually is selected during use of the Wizard Chart Setup program, b) you select Setup from the Chart pull-down menu, c) you right-click on the chart region in ChartView’s Main Window. Note: If multiple chart groups are present in the display configuration, the current group will be selected in the display configuration tree.
Display Configuration Setup Dialog Box with an Existing Configuration Note: When a chart contains overlapping channels [and the channels share values such that their traces reside on top of each other], then the channels listed lower in the display list (the most recently added channels) will obscure the channels higher in the list (those that were added first). Adding Channel 2 to Chart 1 Another variation of the Display Configuration Setup box appears when you highlight a channel.
Adjusting Channel Setup for Channel 1 ChartView and ChartView Plus data channels can operate in one of two modes: Units Full Scale or, Units/Div. The mode is selected by radio button. Units Full Scale. When Units Full Scale is selected, as depicted in the above figure, you can alter Y Max and Y Min. These are the upper and lower limits of the Channel as they will appear on the chart when the channel is selected. When you change either parameter, Y Center and Units/Division are automatically adjusted.
Manually Creating a Display For ChartView Plus users, if you plan to have a chart setup that is not weighted evenly, i.e., different numbers of channels per chart and different numbers of charts per group, you may want to manually setup your chart display from scratch, i.e., without beginning from a pre-existing display configuration. This method is arrived at from the Chart Setup Wizard window by selecting “Manual Chart Creation.
(4a) Automatically add groups to the setup. Enter the number of groups and charts desired by using the cursor and typing in the value, or by using the pull-down arrows (τ) and making the appropriate selections; then click on the Create Groups button. (4b) Manually add groups to the setup. Type in the name of the chart group; then click on the Add Display Group button.
9. Choose channels for the selected chart. With ChartView Plus, you can select up to four overlapping channels per chart. With the basic ChartView program, you are limited to one channel per chart. There are four methods of adding channels. These are as follows: • Highlight an available channel using the cursor and left-hand mouse button; then click the Add button. Repeat for each channel to be added.
Channel Configuration The “Channel Configuration” button brings up the Setup Window with one of three “tabbed” dialog boxes displayed: Acquisition Setup (page 4-33), Channel & Alarm Setup (page 4-33), or Data Destination (page 4-39). The information entered in the Acquisition Setup dialog box is used by the Arm Acquisition command to set up the acquisition of data to disk. When the trigger is satisfied, the scans are collected at the selected scan frequency and stored to disk in the designated file.
Print Charts The Print Charts button activates a screen print of ChartView’s main window. Main Window Pull-Down Menus The ChartView main window features several pull-down menus. As an alternative to the menus, you can enable several menu items by using Toolbar buttons, previously discussed.

Starting PostView The main ways of starting PostView are: 1) Open PostView directly from the Windows Explorer, Desktop Icon, or Start Run browse feature (on desktop). 2) From the acquisition program’s main window, click on the toolbar’s PostView button, or select PostView from the pull-down menu. Each of these methods is illustrated in the following figure. Actions in the decision diamond are performed automatically by PostView and require no user action.
Note: Chart Setup Wizard can be started from the File pull-down menu. Chart Setup Wizard’s use in PostView is discussed on page -7. Toolbar The following table explains PostView toolbar items, while the next page begins a description of PostView Menu items. Menu and toolbar items are shown in the figure below. PostView Toolbar Items Item # 1 Item Description Group Select This feature indicates the chart group, which is being charted.
Channel Information Region By clicking on the up or down arrows (σ, or τ) by the channel selection box (item 11), you can select one channel (of a maximum of 4 overlapping channels) that were assigned to that chart. You could then observe the chart-related information for that specific channel. You can also select a new channel for the information region by placing the cursor in (or tabbing over to) the “Center” or “Units/Div” fields and then pressing PageUp or PageDown.
Menu Items File Open Print Setup Wizard Exit Opens a data file created by the data acquisition program. PostView automatically detects whether the file contains ASCII or binary data. Prints the present PostView window. Accesses Display Configuration Setup dialog box, allowing you to edit the display configuration. Accesses the Chart Setup Wizard. Exits the File menu. Go To Automatically scrolls the waveform such that the displayed waveform begins at the Percentage (Ctrl+P) specified percentage.
Understanding Groups, Charts, and Channels As indicated in the figure on page -3, when no display configuration file is found, PostView opens the Chart Setup Wizard to assist you in creating a display file. To make the best use of Chart Setup Wizard you need to understand the relationship of Groups, Charts, and Channels. The Chart Setup Wizard feature is discussed immediately following this text. Group. “Group” refers to a group of charts.
A Manual Chart Creation, Create Charts button allows you to bypass the Chart Setup Wizard and enter a manual editing mode. This option makes use of PostView’s Display Configuration feature (discussed in the following Display Configuration section). Manual Chart Creation allows you to vary the number of assigned channels per chart, as well as vary the number of charts per group.
It is a simple task to create a chart display configuration using the automatic method. The following steps apply to this feature of Chart Setup Wizard. Note: 1. If PostView locates a display configuration file, Chart Setup Wizard will not be activated unless you choose to manually activate the Wizard from the File pull-down menu. From the Chart Setup Wizard window, select the desired mode (Simple, Moderate, or Advanced).
Editing a Display Display Configuration Setup Dialog Box with an Existing Configuration To explain editing a configuration, we make use of an example in which assumes you want to edit Chart 1. In the following figure, Chart 1 was highlighted by clicking on it with the mouse cursor. The Display Configuration Setup box then changed, allowing you to see specific channel types (such as volts only) or to “Show all Types,” as in the example. From this setup box you can add or delete charts and channels.
Another variation of the Display Configuration Setup box appears when you highlight a channel. In the following figure, Channel 1 (of Chart 1, Group 1) was selected, resulting in a new screen image. From this screen you can edit the channel setup. Adjusting Channel Setup for Channel 1 PostView channels can be set for either of two modes: Units Full Scale or, Units/Div. The mode is selected by radio button. Mode descriptions are as follows: Units Full Scale.
Manually Creating a Display Note: This method of creating a display can only be accessed from the Chart Setup Wizard. It cannot be accessed if PostView is using an existing display configuration file. Unlike editing a display, as just described, this method involves creating a display from scratch. If you plan to have a chart setup which is not weighted evenly, i.e.
Adding a Chart to Group 1 3. Change the number of charts per group if desired. 4. Change the group name if desired. 5. Click on a group to see the chart(s) assigned to the group. In the above example there is one group with one chart. 6. Click on a chart to assign channels to the chart. A screen similar to the following will appear. Assigning Channels to Chart 1 of Group 1 7. Choose channels for the selected chart. You can select up to 4 overlapping channels per chart.
Note: You can remove channels by highlighting a channel(s) in the Select Channels box, and then clicking on the Remove button. In the previous figure, CH7 (in the select box) is highlighted. Clicking the Remove button would delete that channel from Chart1. Note: When a chart contains overlapping channels which share values (such that their traces reside on top of each other), the more recent channel will obscure the earlier channel.
PostView Timebase PostView automatically detects and displays the data file timebase along the X-axis at the bottom of the PostView window. The timebase can be displayed as relative time or as absolute time in the format: 00:00:00.0 (hour/minute/second/tenth). The timebase format of absolute or relative can be selected in PostView’s Option pull-down menu, or by using Ctrl+A or Ctrl+R respectively.
It is possible for the data acquisition program to create files containing multiple timebases, pre-trigger, posttrigger, and post-stop data. PostView accommodates all these features, as shown in the previous example (taken from a ChartScan/1400 unit with the ChartView data acquisition program). • • • If pre-trigger scans are available, they will be shown prior to the trigger point and labeled with negative time numbers.

Rear Panel NetScan’s rear panel contains several items, including a set of LEDs for status indication. The LED indicators are described in the following table. Other rear panel items are listed in a separate table following the illustration. LED Indicators, Chassis ALARM ON when an alarm has occurred. The indicator remains ON until the alarm condition clears. OFF when no alarm condition exists.
Ethernet Interface, section of Rear Panel Activity - ON when data is being sent or received through the internet. LED Indicators Link - ON when the NetScan unit has a solid connection to the internet. Ethernet - ON when the ethernet interface is enabled and functioning properly. OFF when the ethernet interface is disabled. FLASHES when a problem exists that requires factory attention. Accepts a 10Base-T type ethernet cable for connecting to a PC ethernet connector, or to an Ethernet Connector ethernet hub.
4. As indicated in the figure, press down on the switch to change the setting from 115VAC to 230VAC. To change the setting from 230 to 115VAC, you must press up on the switch. 5. Replace NetScan’s cover plate and secure with screws. 6. Add a new sticker, or tag, stating the newly selected voltage.
NetScan provides three options for expanding the standard 256 KB of memory to 1 MB (CSN/MEM1), 4 MB (CSN/MEM4), or 8 MB (CSN/MEM8).
Calibration Memory Write Enable/Disable NetScan’s constants for chassis calibration and the calibration password are stored by NetScan in Non-Volatile RAM (NV-RAM). The password is a safety feature used to prevent unauthorized personnel from entering calibration mode and altering the calibration constants. As a safeguard, the calibration password and chassis calibration constants are hardware protected.
Configuring RS-232/422 Parameters &$87,21 The RS-232/422 interface is only to be used for serial communications. Cable length should not exceed 50 feet (15 meters). Note: The DIP switch is read only when power is applied to NetScan, and for that reason must be set before applying power. Note: Unless an interface option is used, NetScan’s serial port operation will be with RS-232 electrical characteristics.

Digital I/O Lines NetScan has eight digital input lines and thirty-two digital output lines available on a rear panel DB-50 connector. These lines can be output and/or input using NetScan commands. Note: The first 16 output lines are available for use with relays via the high current CSN/Relay card option. If used, the relay card must be installed in slot 1 (bottom slot) of the NetScan main unit. The CSN/Relay card is discussed at the end of this chapter.
External TTL BNC Connectors NetScan’s rear panel provides two external trigger BNC connectors. The BNC TTL Scan output is used for synchronizing equipment with NetScan. NetScan can be programmed to trigger on a rising or falling TTL level. Any TTL level signal (> 2.2V = Hi, < 0.8V = Lo) may be used as a trigger pulse. A trigger pulse may also be used to generate a Service Request. Note that the TTL Out is a LS-TTL compatible output, 0.4 mA sourcing, 8 mA sinking.
CSN14/TC/P Thermocouple and Low Volts Card with Subminiature Plugs The CSN14/TC/P card contains 16 differential input channels, each of which may be configured as any thermocouple type or as a milli-volt input. Temperature values may be returned in units of °C, °F, °K, °R, or mV. This signal conditioning card contains “subminiature plug type” connectors. There are no user configuration switches or jumpers on the CSN14/TC/P card.
Digital Filtering: • Averages 32 samples at 50/60 Hz for line cycle noise rejection (VDC measurements) Voltage Range2, Accuracy3 and Resolution: • ±100 mV ± 0.02% 3.05 µV/bit • ± 0.02% ±1 V 30.5 µV/bit • ± 0.02% ±5 V 153 µV/bit • ± 0.02% ±10 V 306 µV/bit Hardware Note 1: Accuracy is based on 18 to 28°C, 1 year; includes cold junction compensation; excludes thermocouple errors; thermocouple readings based on NIST Monograph 175. Resolution given is the typical value.
CSN14/LV/ (T, B, & S) Low Voltage Cards There are three versions of low voltage signal conditioning cards for use with NetScan. Each card supports 16 differential input channels and is capable of measuring analog input signals on any of four programmable ranges: ±100 mV, ±1 volt, ±5 volt and ±10 volt. The cards share the same signal conditioning characteristics, but differ in their style of input connector, i.e., terminal strip, BNC, and safety jack (CSN14/LV/T, CSN14/LV/B and CSN14/LV/S, respectively).
CSN14/HV/S High Voltage Card with Safety Jack Connectors The CSN14/HV/S card contains 16 differential input channels and is for use with “safety jack” type connectors. Each CSN14/HV/S card is capable of measuring analog input signals on any of the following three programmable ranges: ±2.5 volt, ±25 volt and ±250 volt.
CSN/Relay Card (for High-Current Digital-Output) CSN/Relay Card The high-current digital-output CSN/Relay Card allows you to add relay functions to the first 16 digital outputs. The CSN/Relay card installs into NetScan’s slot 1 (bottom card slot). Only one relay card can be used per NetScan unit, and a relay card can not be installed in a NetScan expansion chassis. The CSN/Relay Card uses 16 dual-coil latch relays and associated circuitry to minimize load on NetScan’s internal power supply.
CSN/Relay Card Specifications Number of Channels: • 16 (2 groups of 8 channels) Relay Contacts (Manufacturer’s Ratings):* • 8 Amps, 125-250 VAC Resistive • 5 Amps, 30 VDC Resistive Card Contact Ratings: • 8 Amps maximum on group commons Contact-to-System Isolation: • 500 Volts (AC or DC) *Manufacturer’s ratings for the relays used on the CSN/Relay Card. Expansion Chassis, CSN/Exp (Option) You can add up to 64 additional analog channels to NetScan by using a CSN/Exp expansion chassis.

Insert one end of the included 40-conductor ribbon cable (CA-154) into NetScan’s connector PH401. PH401 is located above the uppermost signal conditioning connector on the top edge of the analog back plane board.
Automatic Channel Assignment Unless the CSN/Relay card is used, Channels 1 through 64 are automatically assigned to NetScan, while extended channels 65 through 128 are assigned to the expansion chassis. Even if a card slot is left empty in the NetScan or the expansion chassis, the channel assignments are as shown in the table, with slot 1 being at the bottom of the unit, and slot 4 being at the top.
Expansion Chassis Specifications :$51,1* Service must be performed by qualified personnel. All terminals, including the AC line and analog inputs, must be disconnected prior to opening NetScan main unit or expansion chassis casing. Internal voltage potentials exist which could cause bodily injury or death! &$87,21 The Expansion Chassis contains no fuses; However, fuse failure in NetScan’s main chassis indicates a possible problem with device circuitry.

Appendix A API Command Reference *K - Change Calibration Keyword TYPE EXECUTION SYNTAX Calibration Immediate *Kkey Change the calibration keyword, where key is the keyword in the form of a 5digit number nnnnn. Therefore the password can be no longer than 5 characters. DESCRIPTION Note: This command is only for advanced users who perform their own calibration. It is not necessary for normal, everyday operation.
Appendix A API Command Reference *R - Power-On Reset TYPE EXECUTION SYNTAX DESCRIPTION System Immediate *R Power-On Reset. Equivalent to a hardware reset. The Power-On Reset (*R) command has the same effect on the unit as removing and re-applying power. All data in data buffers and configuration are erased. Note: Because the *R command performs a full power-on reset, 3 or 4 seconds are required before you can communicate with the unit.
Appendix A API Command Reference *T - Time Stamping TYPE EXECUTION SYNTAX System Immediate *Tstate Specify whether or not time stamping will be enabled. Valid options for state are: 0 - Disable time stamping (default), 1 - Enable absolute time stamping, and 2 - Enable relative time stamping. DESCRIPTION The Time Stamping (*T) command, when enabled, will append a time/date time stamp to each scan being sent by the unit to the controller: If absolute time stamping is enabled, the format is HH:MM:SS.
Appendix A API Command Reference A - Assign Alarm Output TYPE EXECUTION SYNTAX System Deferred Achans, output A? Set alarm condition where chans is the channel(s) to assign to the digital output. chans may be in two forms: chan (for a single channel where 1 < chan < max) or first-last (for a range of channels where 1 < first < last < max), where max = 128 for NetScan. output is the digital output number with which to associate the channel(s), where 0 < output < 32.
Appendix A API Command Reference A# - Alarm Stamping TYPE EXECUTION SYNTAX System Immediate A#state Specify whether or not alarm stamping will be enabled. Valid options for state are: 0 - Disable alarm stamping (default), and 1 - Enable alarm stamping. DESCRIPTION The Alarm Stamping (A#) command (when enabled) will append the alarm state to the end of each scan as it occurs: The alarm status consists of 32 bits: A31 through A00, each with a 1 signifying alarm on, or a 0 signifying alarm off.
Appendix A API Command Reference C - Configure Channels TYPE EXECUTION SYNTAX Channel Deferred Cchans, type [, [lowsp], [highsp], [hyst] ] C? Configure the channels for the master unit and its slave units. chans and type are required arguments, while lowsp, highsp and hyst are optional. chans may be in two forms: chan (for a single channel where 1 < chan < max) or first-last (for a range of channels where 1 < first < last < max), where max = 128 for NetScan. The chassis is chan = 0.
Appendix A API Command Reference Note: Specifying a reserved type will cause an error. Note: Since the Configure Channels (C) command is a deferred command, the channel(s) will not actually be configured until the Execute (X) command is processed. Also, since the configuring of channels takes a good deal of processor time, it is recommended that as many Configure Channels (C) commands should be placed on one command line as possible.

API Command Reference − A-52 Appendix A Notes NetScan User’s Manual
Appendix B Ethernet API Reference Overview NetScan software provides an ethernet API that allows users to write programs. Support consists of two files, NPCI_WIN.DLL for 16-bit windows developers, and NPCI_W3V.DLL for 32-bit windows developers. The only system requirement is that the Windows TCP/IP protocol be loaded and configured. With a mechanism called session handles, the API can simultaneously handle multiple NetScan units.
nIOLock Function: int nIOLock (long session, short iotype, short channel, short lock); Parameters: Long session The session handle of the NetScan Short iotype Always a 9 Short port The serial port being locked (1 for the netscan, 0 for the AUX port) Short lock 0 to unlock, 1 to lock Returns: 0 if successful, error code if not. Description: This function is used to lock the serial port of the NetScan adapter so that another session can’t have access to it.
nSerialReceive Function: int nSERIALReceive (long session, short port, unsigned short flush, long timeout, short terminator, short length, char FAR *data, short FAR *xlength, unsigned short FAR *status); Parameters: Long session The session handle of the NetScan Short port The port being read from. Unsigned short flush Flag to indicate if the receive buffer should be cleared. long timeout The time, in milliseconds, to wait for received data. Short terminator The terminator to be used for serial input.
nSerialSend Function: int nSERIALSend (long session, short port, unsigned short flush, long timeout, short terminator, short length, char FAR *data, short FAR *xlength, unsigned short FAR *status); Parameters: Long session The session handle of the NetScan Short port The port being read from. Unsigned short flush Flag to indicate if the receive buffer should be cleared. long timeout The time, in milliseconds, to wait for received data. Short terminator The terminator to be used for serial input.
Appendix C Configuration Aspects for Programmers Reference Note: If you are not familiar with programming you will probably gain more understanding of the program-related portions of this appendix by first reviewing Appendix A, API Commands. Reference Note: Hardware configuration is discussed in Chapter 7.
Configuration Aspects for Programmers Appendix C Memory Allocation Each NetScan comes equipped with 256 KB memory. There are three options for additional memory: 1 Mbyte, 4 Mbytes, and 8 Mbytes. The memory modules are located in SIMM sockets JP201 and/or JP202 on the microprocessor board. Refer to Chapter 3 if you intend to add or remove memory modules. Regardless of the memory option used, NetScan will automatically allocate its memory for optimal use according to its current configuration.
Appendix C Configuration Aspects for Programmers Measuring Modes Overview You can select either of two scanning modes for NetScan, 1) Normal mode or 2) High-speed, single channel mode. Mode “Average weight” Setting 16, 32, 64, 128, or 256 1, 2, 4, or 8 Normal High-speed, single-channel not selectable NetScan Measuring Modes Application Recommended for AC noise rejection. Recommended for high-speed, multiple channel applications for thermocouples and DC voltages where noise filtering is not an issue.
Configuration Aspects for Programmers Appendix C Normal Mode NetScan has the ability to reject noise resulting from AC line pick-up when an Average weight setting of 16 or more measurements per line cycle is used. This noise rejection factor is important, as it allows for higher accuracy.
Appendix C Configuration Aspects for Programmers High-Speed, Single-Channel Mode The High-speed, single-channel mode, also known as burst mode, is used for post-acquisition waveform analysis of AC and DC voltages. In this mode, NetScan can sample from 38.5 Hz to 20.0 kHz, and store the data in memory. Note that NetScan’s memory can be expanded up to 8 Mbytes. When performing post-acquisition waveform analysis, such as Fast Fourier transforms, NetScan can return each data point in a waveform.
Configuration Aspects for Programmers Appendix C The remainder of this appendix and the next, pertaining to acquisition setup, refer to normal mode acquisitions only. Configuration Requirements NetScan does not scan channels on its initial power-up. Even though most user-set configuration states have associated defaults, you must configure a few items before scanning begins.
Appendix C Configuration Aspects for Programmers Reference Note: If you are not familiar with programming you will probably gain more understanding of the program-related portions of this appendix by first reviewing Appendix A, API Commands. PRINT#1,"C1-4,1X" ‘ Configure master channels 1-4 with Type JTC PRINT#1,"I00:01:00.0,00:00:01.
Configuration Aspects for Programmers Appendix C CSN14/TC/P Configuring Thermocouple Channels Begin configuring input channels by first specifying the channel type. When the CSN14/TC/P signal conditioning module is used, 16 differential thermocouple inputs are provided. In configuring thermocouple (T/C) channels, all that is required is to assign each channel to a particular T/C type. Support for B, E, J, K, R, S, T and N (14 and 28 gauge) thermocouple types are standard.
Appendix C Configuration Aspects for Programmers CSN14/HV/S Configuring High Volts Channels When the CSN14/HV/S signal conditioning module is used, NetScan measures high voltages providing a programmable range per channel. To configure the channels on a CSN14/HV/S, use the Configure Channel (C) command to assign a range to each channel on the signal conditioning module. Channels not included in the channel scan do not have to be configured.
Configuration Aspects for Programmers Appendix C The I command is used to set these two scan intervals. For example, the following command: I00:00:10.0,00:00:00.1 would set the scan interval to once every 10 seconds and set the post-trigger scan interval to once every 0.1 seconds. As mentioned earlier, the scan interval can be set to run as fast as the current configuration will allow. This is referred to as fast mode. Each of the two scan intervals can be configured as such by specifying 00:00:00.
Appendix C Configuration Aspects for Programmers Pre-Trigger State The Pre-Trigger state is defined as the period after NetScan has been configured to collect an acquisition (via the Trigger Configuration T command), and before the actual Trigger event occurs. While the unit is in this state, the TRIGGER LED will flash. As in any other acquisition state, the alarms and their associated outputs will be updated at the fastest rate possible under the current channel configuration.
Configuration Aspects for Programmers Appendix C To enable this functionality you must perform the following steps: 1. Set the first parameter of the Counts (Y) command to -1. If more than one transition cycle is desired, enable the Auto-Rearm flag of the Trigger Configuration command. If this is done, each transition cycle will be stored in its own Trigger Block within the buffer. 2. Set the timebase intervals for each event using the Timebase Interval (I) command. 3.
Appendix C Configuration Aspects for Programmers Post-Trigger State The Post-Trigger state is the period between the occurrence of the trigger event and the occurrence of the stop event. While the unit is in this state the TRIGGER LED will be on and the alarms and their associated outputs will be updated at the post-trigger scan rate. During the Post-Trigger state the unit will collect Post-Trigger data at the rate specified by the acquisition scan interval specified by the Scan Interval (I) command.
Configuration Aspects for Programmers Appendix C In order for an acquisition to take place, the unit must have a trigger event and can be assigned a Stop Event. This allows different stimuli to begin and end an acquisition. Note: If the trigger start event is level or alarm, at least one pre-trigger scan must be programmed to initiate scanning in order for the NetScan to recognize the event. External TTL (High or Low Level) Start and/or Stop Event.
Appendix C Configuration Aspects for Programmers Time Stamping (*T) As mentioned in the previous sections, the contents of each scan contains one reading for each defined channel. Optionally, time stamping of each scan can be enabled with the *T command. *T1 enables absolute time stamping, *T2 enables relative time stamping, while *T0 disables time stamping. Refer to the *T command description for further details.
Configuration Aspects for Programmers Appendix C With Alarm Stamping: ‘ Enable alarm stamping ‘ Configure and start an acquisition PRINT#1, “R1X” ‘ Request the next scan in the buffer LINE INPUT#1, A$ ‘ Retrieve it PRINT A$ ‘ ....+0234.20-0019.40+0001.40+0023.60 005 128 032 066 PRINT#1, “A#1X” Digital Input Stamping (I#) Digital Input Stamping (I#) allows you to see whether a digital input was “active” or “inactive” at the time of the scan.
Appendix C Configuration Aspects for Programmers With Digital Input Stamping: PRINT#1, “I#1X” ‘ ‘ ‘ ‘ Enable digital input stamping Configure and start an acquisition Request the next scan in the buffer Retrieve it PRINT#1, “R1X” LINE INPUT#1, A$ PRINT A$ ....+0234.20-0019.40+0001.40+0023.60 036 000 The last six digits are the digital input stamping; however, the last three digits are not used, and will always appear as 000. The following explains how to interpret the stamping codes.
Configuration Aspects for Programmers Appendix C Acquisition Buffer, A Description Once scans are read from the buffer by the controlling computer, they are erased from NetScan’s buffer. The acquisition buffer is a FIFO (First-In First-Out) buffer. In other words, the oldest data to be written into the buffer is the first data to be read from the buffer when a read operation is performed. The buffer may be broken up into one or more “trigger blocks.
Appendix C Configuration Aspects for Programmers This response indicates that the first available scan is -0000076, which is a pre-trigger scan. This scan can be retrieved as follows: PRINT#1,”R1X” ‘ Get the -0000076 scan LINE INPUT#1,A$ ‘ Get the scan PRINT A$ ‘ Screen shows (4 channels configured) … +1234.50-0234.20+0984.00+0323.30 PRINT#1,”U6X” ‘ Now get status of current read trigger block LINE INPUT#1,A$ ‘ Get the response PRINT A$ ‘ Screen shows… 000001,001233,-0000075,12:34:54.
Configuration Aspects for Programmers Appendix C Multiple Trigger Blocks Through the Auto-Rearm capability of the NetScan, it is possible to capture more than one trigger block in the unit’s Acquisition Buffer. Each trigger block would contain one and only one trigger point. These trigger blocks are stacked end-to-end in the buffer; as the last reading of the first trigger block is read by the controller, the next scan to be read will be from the second trigger block.
Appendix C Configuration Aspects for Programmers Acquisition Buffer Interrogation Note: In the following sections “current trigger block” always refers to the trigger block that is currently being read. The current status of the acquisition buffer may be interrogated at any time by issuing the Buffer Status String (U6) command. As mentioned earlier, the U6 command is a user query command which will return information regarding the current state of the acquisition buffer.
Configuration Aspects for Programmers Appendix C 7 - End Scan Pointer This field represents the location in the current trigger block that the end scan occurred. This pointer will always be relative to the trigger point. Since the end scan must always occur after the trigger event this pointer will always be greater than 0. If the end scan has not yet occurred at the time of the U6 query, this field will have the value of -0999999.
Appendix C Configuration Aspects for Programmers The following figures and table illustrate a case in which an acquisition has been triggered, the stop event and end scan have occurred, and the buffer contains several trigger blocks. Field 1 2 3 4 5 Response 0000007 0020567 -00000100 Implication Seven trigger blocks are available. 20,567 scans are available. The current read pointer is at scan number -100 (negative 100). 12:01:43.100, 03/01/97 The trigger time stamp is defined as indicated.
Configuration Aspects for Programmers Appendix C Reading the Acquisition Buffer The three previous sections briefly discussed how the acquisition buffer may be accessed and read. In this section the methods by which the acquisition buffer is read will be discussed in more detail. As mentioned earlier, the Acquisition Buffer is organized as a FIFO (First In, First Out). As such all data read from the Acquisition Buffer will be the oldest available data.
Appendix C Configuration Aspects for Programmers The R2 command will read the oldest available trigger block in the Acquisition Buffer. For instance, continuing with the previous example: PRINT#1,"U6X" LINE INPUT #1,A$ PRINT A$ ‘ Request the current status of the Acquisition Buffer ‘ Retrieve it. ‘ Screen shows... 0000006,0020215,-00000099,12:51:43.100,03/24/97,00000100,01:53:01.
Configuration Aspects for Programmers Appendix C Configuring Alarms NetScan can produce an internal event when the value of a channel is outside of user-defined limits. These “alarm events” can be used as trigger or stop events, or as a stimulus for TTL-level signals on the NetScan back panel. To use alarms the channels in question must be part of the channel scan. The alarms will become active and monitored only after an acquisition has been configured and armed, and only at the programmed scan rate.
Appendix C Configuration Aspects for Programmers As mentioned above more than one channel can be assigned to any given output bit. For example, if the following statement were appended to the above example, then either channel 2 or channel 3 will set digital output #2.
Configuration Aspects for Programmers Appendix C Digital I/O Operation As shown in the DB50 pinout in the Installation and Configuration section, the NetScan has digital I/O pins for eight inputs and thirty-two outputs (see note). The digital outputs can be controlled either automatically via the alarm settings or with programming using the Set Digital Outputs (O) command. To determine the digital output state, use the O? command.
Appendix D Registers, Data Formats, & Queries Reference Note: If you are not familiar with programming you will probably gain more understanding of the program-related portions of this appendix by first reviewing Appendix A, API Commands.
Registers, Data Formats, & Queries Appendix D Using High/Low/Last (HLL) Registers The High/Low/Last (HLL) registers are an alternative method of getting channel data from the NetScan. The HLL registers are updated during an acquisition and at the current programmed scan rate. At any time, the HLL registers can be queried for channel values without affecting the buffered data. The returned data will be in the engineering unit and format (ASCII or binary) defined by the user.
Appendix D Registers, Data Formats, & Queries You can use the Query Terminator (Q) command to specify a response terminator between each channel of the HLL response. Use the Format (F) command to specify the output format of the HLL Registers. The following examples show how to use these commands to configure and query the HLL Registers. Example 1: Example 1 shows how to configure and query all the HLL registers and how the HLL terminator can be used to control the flow of the HLL response output.
Appendix D Registers, Data Formats, & Queries Example 3: Example shows how to read only the Last readings. PRINT#1,"F0,0 Q1,1,0,0, 0X" PRINT#1,"C1-4,1X" . . . PRINT#1,"U13X" INPUT #1, A$ PRINT A$ +0950.30 INPUT #1, A$ PRINT A$ +0250.60 INPUT #1, A$ PRINT A$ -0050.80 INPUT #1, A$ PRINT A$ +0010.
Appendix D Registers, Data Formats, & Queries Example 6: Example 6 shows how to retrieve Last readings for a subset of the configured channels. PRINT#1,"F0,0 Q1,1,0,0,0X" ‘ Set format to ASCII degrees C with ‘ HLL terminator ‘ of CR LF/EOI ‘ Configure four channel (no setpoints) PRINT#1,”C1-4,1X" . . . ‘ ‘ ‘ ‘ PRINT#1,"R#2-3X" INPUT#1, A$ PRINT A$ +0250.60 INPUT#1, A$ PRINT A$ -0049.
Appendix D Registers, Data Formats, & Queries Data Output Formats Data Output formats differ slightly from data input formats in that binary formats may be used for Channel Data. Channel Data is the only output data which may use the binary format (if it is specified). Channel Data is defined as data originating from the High/Low/Last (HLL) Registers or the Acquisition Buffer. The commands that initiate Channel Data output are the R, R#, U4, U5 and U13 commands.
Appendix D Registers, Data Formats, & Queries Volts The default NetScan system units and resolution are dependent on the low or high volts range: Low Range Resolution High Range Resolution ±100 mV ±1 V ±5 V ±10 V 3.12 µV/bit 31.21 µV/bit 156.06 µV/bit 312.12 µV/bit ±2.5 V ±25 V ±250 V 78.75 µV/bit 787.46 µV/bit 7.87 mV/bit The default binary format returns 2 bytes of 2’s complement binary data with the user selecting low/high byte or high/low byte.
Appendix D Registers, Data Formats, & Queries Binary Data Format Only High/Low/Last (HLL) register and acquisition output data, may be in binary format. Binary formatted data can be output in either highbyte/lowbyte or lowbyte/highbyte format. Time/Date Stamp If binary format is selected, the High/Low/Last register values will also include time/date stamps.
Appendix D Registers, Data Formats, & Queries Configuring Power-Up State The NetScan has an internally stored factory default configuration which can be recalled at any time. You can program the NetScan to power-up in a “user-defined” state, or if desired, can configure the unit to power-up with the default configuration. During normal operations the factory defaults may be recalled by issuing the Restore Factory Defaults (*F) command.
Registers, Data Formats, & Queries Appendix D Queries The NetScan provides many ways to query the unit for specific information. Most commands have a corresponding query command which responds with the configuration or mode of a previously executed command. In addition, the U Status commands can be used at any time (without interfering with normal operation) to return information about the various NetScan conditions.
Appendix D Registers, Data Formats, & Queries U Commands and Descriptions U0 U1 U2 U3 U4 U5 U6 U7 U8 U9 U10 U11 U12 U13 U14 U15 U16 U17 U18 Returns information in the Event Status Register. Returns information in the Status Register. Returns information in the Calibration Status Register.

Appendix D Registers, Data Formats, & Queries Calibration Status Register (U2 Command) The calibration status register indicates which calibration errors, if any have occurred. The individual errors are described in the U2 command. Any calibration error will be mapped into the Calibration Status which maps to the Calibration Error bit in the Error Source Register. Error Source Register (E? Command) The error source register indicates which errors, if any, have occurred.

The alarm is cleared when the alarm condition no longer exists. DI02 Trigger Detected Set when the NetScan has detected the trigger condition and will be cleared when the acquisition is complete or the trigger has been reconfigured. DI03 Ready Set when the NetScan is ready to process another command.
Appendix D Registers, Data Formats, & Queries Trigger Latency Each trigger source has an associated latency. This is the time between the actual trigger and its recognition by the acquisition device. The following latency times are only representative of the time between when the trigger is detected and when the trigger has been processed. Hardware latency times and ISR servicing of other tasks at the time of the trigger event but before the trigger is detected are not accounted for.
Registers, Data Formats, & Queries Appendix D Buffer Overrun With One Trigger Block When only one trigger block is in the buffer, a buffer overrun will erase the entire pre-trigger. If the controller was reading pre-trigger data from the buffer, the next scan read will be the trigger point. If no pre-trigger was configured or the pre-trigger has already been read, a buffer overrun will only erase the oldest scan in the buffer.
Appendix E NetScan Program Examples Note As this manual goes to press, program examples do not exist. However, program examples should be available on the release disk in the EXAMPLES subdirectory (of the CHARTVIEW directory).
