Overview Introduction Introduction 1 1-1. The 2640A and 2645A NetDAQ Networked Data Acquisition Units are 20-channel front ends that operate in conjunction with NetDAQ Logger for Windows (hereafter known as NetDAQ Logger) to form a data acquisition system. The instruments measure dc volts, ac volts, Ohms, temperature, frequency, and dc current. Temperature measurements use thermocouples or resistance-temperature detectors (RTDs). To measure other parameters, use an appropriate transducer.
2640A/2645A NetDAQ Users Manual Instrument Features and Capabilities 1-2. The following describes the front and rear panels of the instrument and its capabilities (Figures 1-2 to 1-4). Primary, Secondary, and Annunciator Displays. Indicators and annunciators for operating mode, configuration, display, and data measurements.
Overview Instrument Features and Capabilities REM (Remote) Annunciator. Indicates the Host Computer and the Instrument are communicating on the network, i.e., the instrument is being operated remotely. SCAN (Scanning) Annunciator. Indicates the instrument is scanning. MON (Monitor) Annunciator. Indicates the instrument is monitoring a channel (in this example, analog channel 8). You can monitor a channel with or without instrument scanning. 1 1208 (Global Channel Number).
2640A/2645A NetDAQ Users Manual Ground Terminal. Connects mainframe to ground. Ethernet 10BaseT Connector. A RJ-45 connector that interfaces the instrument with a 10BaseT Twisted-Pair Ethernet network. The instrument automatically selects the active 10Base2 or 10BaseT connector. Universal Input Module. Directly wires 20 analog inputs (Channels 1 to 20) without need for external signal conditioning. Power Switch. Applies power to the instrument (ac or dc operation). AC Power Connector.
Overview Instrument Features and Capabilities Analog Channels 1 1-3. The analog channel (1 to 20) measurement connections are made via the Universal Input Module. External signal conditioning for the analog inputs is not necessary. The host computer configures all analog channels using NetDAQ Logger. Computed Channels 1-4. In addition to the 20 analog channels, the instrument provides an additional 10 computed channels (21 to 30) by processing analog channels and other computed channels.
2640A/2645A NetDAQ Users Manual Alarms 1-7. Two alarms, Alarm 1 and Alarm 2, can be applied to any configured channel. An alarm condition occurs when a measurement falls below a low alarm value or rises above a high alarm value. You can use alarms to trigger scanning (see “Alarm Triggering”) and to set a Digital I/O line to a logic low (see “Digital I/O” below). NetDAQ Logger displays and records alarm conditions.
Overview Instrument Features and Capabilities 1 overflows (reaching the maximum count), the display briefly shows OL (overload) and begins counting from zero again A totalizer input from contact closures increments on the “open” portion of the switch sequence close-open. To prevent switch contact “bounce” from triggering false readings, select the Totalizer Debounce feature. A totalizer input from voltage transitions increments during low-to-high voltage transitions with a nominal threshold of +1.4 volts.
40A/2645A NetDAQ Users Manual Master Alarm 1-13. Master Alarm is an instrument output line that is logic low (nominal +0.8V dc) for as long as any channel is in alarm while scanning is active. The connection uses the ALARM/TRIGGER I/O terminals MA and GND (Figure 1-4). This TTL output interfaces with external equipment such as warning lights, alarms, automatic shutdowns, and paging systems.
Overview NetDAQ Logger Features and Capabilities 1 You can combine Alarm Trigger with External Trigger and Interval Trigger. For example, set the Interval Trigger for 60 seconds (Interval 1) and the Alarm Trigger for 10 seconds (Interval 2). Scanning is at 60-second intervals except when a channel designated as an alarm trigger is in alarm, when scanning is at 10second intervals. NetDAQ Logger Features and Capabilities 1-17. NetDAQ Logger is the operating software for NetDAQ instruments.
2640A/2645A NetDAQ Users Manual operations refer to the instrument by BCN. NetDAQ Logger supports up to 20 instruments for operation. You cannot operate an instrument from more than one host computer at a time. Isolated Networks 1-19. An isolated network consists of only NetDAQ instruments and host computers. The advantages include simplified setup, faster network operation, and freedom from general network problems. Data throughput specifications are guaranteed only for isolated networks.
Overview Host Computer Requirements 1 Designate one instrument in the group as the Master and the others as Slaves. The Master controls scanning operations, including the scan intervals and method of scan triggering. You can create only one group instrument. Scanning and Logging 1-24. When a scan is triggered, the instrument scans the 20 analog channels and calculates the 10 computed channels. It stores the resulting time-stamped data in a scan record.
2640A/2645A NetDAQ Users Manual Host Computer Requirements 1-26. The host computer used for instrument operations must meet the following minimum requirements: • IBM PC with an Intel 386 microprocessor or greater, running Windows 95, Windows NT, or Windows 3.1. • Color VGA Monitor. • A Hard disk drive with 2 MB of free disk space. • A 1.44 Mbyte (3 1/2-inch) floppy disk drive.

Appendix B Noise, Shielding, and Crosstalk Considerations Introduction B-1. This appendix supplies information on how you can setup your instruments to minimize measurement errors. The topics include static versus dynamic measurement, noise and shielding, and how to minimize crosstalk effects Static Versus Dynamic Measurements B-2. Some signals change value slowly. Other change rapidly. At some point things change quickly enough that we call the signals dynamic rather than static.
2640A/2645A NetDAQ Users Manual reading rate and scan interval that is an exact multiple of the power line period and cause line frequency noise to be aliased to a very low frequency, where it appears as drift, or instability, in the readings. For example, if the instrument is set to Reading Rate = Fast and a scan interval of 100 ms, line frequency noise is aliased because the scan interval is an exact multiple of the period of the power line.
Noise, Shielding, and Crosstalk Considerations Crosstalk Considerations B the routing of your input wiring: keep it away from or shielded from all ac power mains wiring and other sources of noise. 3. Channel Spacing When possible, leave as many unused channels as possible between your ac voltage channel inputs and your low level inputs.

Appendix C True-RMS Measurements Introduction C-1. The instrument measures the true rms value of ac voltages. In physical terms, the rms (root-mean-square) value of an waveform is the equivalent dc value that causes the same amount of heat to be dissipated in a resistor. True rms measurement greatly implies the analysis of complex ac signals. Since the rms value is the dc equivalent of the original waveform, it provides a reliable basis for comparing dissimilar waveforms.
2640A/2645A NetDAQ Users Manual 1.0000V ac (the dc component equals 0). However, consider the 2V (peak-topeak) square wave. Both types of measurement correctly display the dc component (0V), but the NetDAQ instrument also correctly measures the ac component (1.0000V). The average-responding device measures 1.11V, which amounts to an 11% error. Average-responding measurement devices have been in use for a long time; you may have accumulated test or reference data based on such instruments.

RTD Linearization Custom-385 RTD Using the Custom-385 RTD with Other Platinum RTDs D D-4. Although the Custom-385 RTD linearization uses a β and δ from a 385 RTD, other RTD types can be used. The Custom-385 linearization will compensate for the change in α, but errors will be introduced due to the difference in the δ and β coefficients of the RTD and the fixed coefficients. Figure D-2 shows the accuracy envelope for a 375 RTD.

Appendix I Network Considerations Introduction I-1. This is a tutorial on commonly used Network communication technology and how to get started using the NetDAQ instruments. It’s not necessary to know the details of Network communication methods in order to use NetDAQ effectively. However, there are such a wide variety of Network techniques and technology in use that you can become lost in the jargon used by Network Professionals. This tutorial will attempt to take some of the mystery out of Networking.
0A/2645A NetDAQ Users Manual low system data throughput because of the processing rate of host computers and disk systems, and instruments that are physically close to the host computer. Now, the increased processing capability of affordable host computers, increased channel measurement rates, and pressure to place the instruments close to the signal source have made support of high-speed, long distance communication techniques necessary.
Network Considerations Network Primer I 2. Does the network contain more than one subnet? If so, what’s the IP address of my default gateway or router device? 3. Will all the routers route IP packets? 4. What are my domain and host names (optional)? The minimum information you need to get is the IP Addresses for the PC and the instruments.
2640A/2645A NetDAQ Users Manual the computers and other devices attached to the network wiring. The Ethernet standard consists of a set of low-level addressing and data transmission protocols that run on several different wiring schemes. Computers on a network are usually referred to as a “host.” The NetDAQ instruments are hosts in this context.
Network Considerations Network Primer • A Repeater is a device used to physically isolate and extend the length of a network segment, but it does not divide the network into subnets. • A hub is a device that allows communication among multiple 10BaseT network hosts and allows these hosts to communicate with other Ethernet wiring. Some hubs also perform Router functions.
2640A/2645A NetDAQ Users Manual strips off the Frame information around the packet. So, unless you’re doing lowlevel analysis of network traffic, you never need to deal with Frame information. For any protocol, the Packet consists of a destination address, a source address, some protocol type information, a message length field, and error detection information. The TCP/IP protocol adds additional fields to the packet for message sequence determination and application port ID.
Network Considerations Network Primer I The IP address provides two pieces of information: the network ID and the host ID. The network ID must be unique among all network subnets within a connected Internet. It identifies the network subnet to which a host is connected. The host ID must be unique among hosts within a network subnet and identifies the host within the subnet.
2640A/2645A NetDAQ Users Manual ID portion to be the higher order 24 bits of the IP address (a class C address). Using the Subnet Mask, the TCP/IP software is able to detect if a destination address is in the local subnet or if the packet must be sent to another subnet through a Router or Gateway. Networks are segmented by use of an active device called a Router (Gateways and hubs sometimes have router capabilities.
Network Considerations Network Primer I software sends out a broadcast frame that every TCP/IP host and router receives. This frame contains a request for the host with the unknown IP address to return a frame to the ARP requester. This response frame contains the Ethernet address of the sourcing host, and this information is then added to the address correspondence table. All communication with a host can then be done with information from the table.
2640A/2645A NetDAQ Users Manual Packet drivers support only one protocol at a time. As a result, only one package of protocol software can use a packet driver at any one time. Packet drivers are usually loaded by executing a *.com or an *.exe file in the autoexec.bat. This loads a terminate and stay resident (TSR) program during the DOS boot process. The setup of the packet driver is usually done by including command line switches on the driver load line.
Network Considerations Network Primer I While a protocol section might look like the following: [NETMANAGE] DRIVERNAME=NETMNG$ BINDINGS=EtherLinkII These two protocol.ini file sections describe a hardware driver characteristic for a 3COM EtherLink II hardware card and specifies that the NetManage protocol stack should bind with the EtherLink II driver. The setup information for ODI drivers is contained in a file called net.cfg that must be in the Novell directory (the driver must be there too).
2640A/2645A NetDAQ Users Manual Currently, the WINSOCK DLL that operates with LAN Workplace must be downloaded from the Novell forum on CompuServe or you must request a copy from Novell. TCP/IP protocol packages with included WINSOCK DLLs can be purchased from a variety of sources including Microsoft, Banyan, FTP, SunSoft, and IBM. The Transmission Control Protocol/Internet Protocol (TCP/IP) has evolved as a networking protocol that supports communication among diverse computers and devices (at U.C.
Network Considerations Notes to Network Administrators I matching network ID. This process is generally referred to as routing the packet, and devices that do this are also referred to as Routers or Gateways. In many modern networks, the use of subnet masking and the default gateway is not necessary. These networks contain routers and gateways that support the Proxy ARP protocol. In this protocol, the routing path between any two hosts is automatically established by the routers during the ARP process.
2640A/2645A NetDAQ Users Manual ARP protocol or have static routing tables, you don’t have to use these parameters. In the Proxy ARP protocol, the routing path between any two hosts is automatically established by the routers during the ARP process. The NetDAQ PC software communicates with the NetDAQ instruments in a totally peer-to-peer manner. Operation of the instruments and software require no server support.
Network Considerations Running Two Network Cards in a PC I If your network contains routers, bridges, gateways, or other devices that divide the network into subnets, and you intend to have the PC on a different subnet from the NetDAQ instrument(s), you need to make sure that the devices can route IP packets. This is especially true on Novell networks, where the network may contain devices that can route only IPX packets.
2640A/2645A NetDAQ Users Manual Network drivers typically use PC soft interrupts to communicate with the protocol software. If you’re using two network cards, and as a result, two drivers, you must select two different soft interrupt levels for the drivers. For example, Packet drivers (used with Trumpet) usually use soft interrupt level 60 (hex). If two packet drivers are resident, one can use 60, but the other must use something else (like 61).
Network Considerations Troubleshooting Information I NetDAQ instrument and the PC default gateway addresses to make sure they are set correctly. Check all network wiring. Make sure that 10Base2 terminators are placed at the two open ends of the coax. Make sure that there is no more than one terminator on each end (some network repeaters, bridges, and routers have termination built into the unit.) In a 10Base2 network, make sure that the collision indicator on the instruments (amber LED) is not lighting.
2640A/2645A NetDAQ Users Manual Move your instrument to a less loaded subnet of your network or isolate the NetDAQ instruments on their own network. If possible, increase the scan interval. Use the Fast Binary file format rather than CSV or Trend Link formats. Make sure that there are few or no other Windows applications running at the same time as NetDAQ Logger. Upgrade to a faster PC and disk drive and increase the amount of RAM in your PC.
Network Considerations Handling Token Ring Networks I 7. Failure to communicate when using the Parallel to LAN Adapter (PLA) In some computers the speed of the parallel port hardware is insufficient to support the normal bi-directional communication used by the Silicom PLA. In these rare cases, you must force use of the uni-directional communication on this interface. You do this by adding the unidir switch to the driver.
2640A/2645A NetDAQ Users Manual If you install Newt networking software on a token ring network on Windows 3.1, the Newt installation procedure must be modified slightly. When prompted for the interface type in the “Add Interface” dialog box, use the list pull-down control to display the other types. From the type list, select “Token Ring”, then hit the OK button on the dialog box.
Network Considerations Newt Networking Software I Ethernet Components and Wiring The NetDAQ instruments and host computer should be connected to the network as shown in Chapter 2 of this manual. Instrument Preparation Each NetDAQ instrument should be connected to an ac outlet or dc source with a proper ground. The instrument’s line frequency and network parameters should be set properly (see “Instrument Preparation” in Chapter 2 of this manual).
