Daq Systems, a Brief Overview 1 Daq Systems, the Modular Concept …… 1-1 DaqBooks and DaqBoards …… 1-2 Using DBK Cards and Modules for Signal Conditioning ….. 1-2 Daq Software ……1-3 Daq Systems, the Modular Concept Daq equipment and software form a modular, interrelated family of products that provide great flexibility in data acquisition system design.
DaqBooks and DaqBoards Daq products connect to one or more DBKs on their signal input side and a computer on their output side. Each type of Daq device connects to the computer in a different way: • The DaqBook is an external module that connects to a computer’s enhanced parallel port (EPP) interface or PC-Card link. • The DaqBoard [ISA type] board is an internal card that plugs into an ISA-bus slot within a computer.
DBK output signals can be bipolar, e.g., -5 to +5 V, or unipolar, e.g., 0 to 10 V. The user can select a range of relevant values to correspond to the lowest signal (e.g., -5 or 0 V) and the highest signal (e.g., 5 or 10 V) signal. This type of range selection guarantees the highest resolution in 12-bit or 16-bit conversion. DBK modules share the same footprint as the DaqBook and a typical notebook PCs; allowing for convenient stacking.
Reference Notes: The software document modules, DaqView, DaqViewXL, and Post Acquisition Data Analysis User’s Guide, are not included as part of the hardcopy manual, but are available in PDF version. See the PDF Note, below. Programming topics are covered in the Programmer’s User Manual (p/n OMB-1008-0901). As a part of product support, this manual is automatically loaded onto your hard drive during software installation.
Setup and Startup 2 For DaqBook/100, /112, /120, /200, /216, /260* This chapter provides instructions for getting a DaqBook configured, connected, installing the appropriate software, and powering up the system. The figure, later on this page, provides an overview of the steps necessary for a successful setup. Reference Notes: DaqBook/260 Users: Instructions detailing the removal of the slide-out drawer and steps for installing internal cards are provided in Chapter 3 of this manual.
(1) Set Jumpers (a) Place the unit on a flat, stable surface. Ensure no power or signal lines are connected. (b) Remove cover screw(s), and slide the top cover plate free of the device. All jumpers are accessible from above the board, and no further disassembly is required. (c) Set jumpers JP1 through JP4 as needed for your application. Jumper configuration options follow shortly. Note that jumpers are clearly labeled on the actual motherboards.
JP2 – DAC Reference Voltage and SSH (Simultaneous Sample and Hold) JP2 selects an Internal (default) or External reference voltage for the two separate analog outputs. JP2 also selects SSH (default) for applications using one or more of the following: DBK2, DBK4, DBK5, DBK7, DBK17, DBK50, or DBK51. We recommend that you leave these jumpers at the factory default setting (see figure at right). Refer to the JP2 material in chapter 3 prior to making changes.
If connecting your DaqBook to a notebook PC, you can use a WBK20A, PCMCIA Interface Card. Refer to separate instructions (supplied with the WBK20A) if applicable. If connecting your DaqBook to a desktop PC (with no available EPP port), you can use a WBK21 Interface card. Refer to separate instructions (supplied with the WBK21) if applicable. WBK21 Interface Card WBK20A Interface Card Reference Note: It is possible to use a VDC power source other than an AC-to-DC adapter.
(5) Test Hardware (a) Run the Daq Configuration control panel applet. (b) Click “Add Device.” (c) Select your DaqBook model from the “Device Type” scroll box and click OK. (d) Select your DaqBook from the “Device Inventory” window and click “Properties.” (e) Ensure settings are correct, and make changes if needed. Device Type Window (f) Select the Test Hardware tab. (g) Verify DaqBook has been properly installed and powered-on.
Performance Tests Performance tests are intended to test various DaqBook functions with the current device configuration. These tests give quantitative results for each supported functional group. The results represent maximum rates at which the various operations can be performed. These rates depend on the selected parallel port protocol and will vary according to port hardware capabilities.
A Closer Look at DaqBook Hardware 3 DaqBook/100,/112,/120,/200, and /216 ……3-1 In General …… 3-1 DaqBook Differences …… 3-1 Performance Factors …… 3-2 Front and Rear Panels ……3-2 Jumpers ……3-4 Connections ……3-7 DaqBook/260 …… 3-12 Front and Rear Panels ……3-12 Hardware Setup ……3-13 Stacking Hardware ……3-17 Using Dual-Lock Tabs and Splice Plates …… 3-17 Using T-Cables ……3-18 DaqBook/100, /112, /120, /200, and /216 In General DaqBooks consist of boards enclosed in a 8.5 × 11 × 1.
Performance Factors DaqBooks are flexible when it comes to analog input capabilities. The A/D maximum sample rate is 100 kHz (divide by number of channels for scan rate) with a 16-channel multiplexer and a programmablegain input amplifier. Users can expand channel capacity to 256 analog inputs via expansion modules for multiplexing RTDs, thermocouples, strain gages, anti-aliasing filters, and simultaneous sample and hold amplifiers.
Front and Rear Panels Excluding DaqBook/260 The following illustrations show the relative locations of connectors, power switches, indicator LEDs, and the expansion slot, as applicable. DaqBook/260 is treated separately in an upcoming section. Reference Note: DaqBook/260 users should refer to page 3-12 for information specific to that product.
Jumpers Proper installation requires that several jumpers and switches be set correctly for your application. These jumpers and switches are located inside the DaqBook enclosure and possibly on your DBKs. Jumpers for the various DaqBook models are configured similarly except for the jumpers’ relative locations. Silkscreening on the motherboard identifies jumpers and switches. Note: Even if using the default settings, you should verify actual jumper positions.
Reference Note: The Power Management section of the DBK Option Cards and Modules User’s Manual (p/n OMB-457-0905) contains additional power-related information. As a part of product support, this manual is automatically loaded onto your hard drive during software installation. The default location is the Programs directory, which can be accessed through the Windows Desktop.
Bipolar or Unipolar A/D Operation (JP3)* *Hardware Setting For DaqBook/100, DaqBook /112, and DaqBook /120 Only The A/D converter in the DaqBook can be operated in two modes, bipolar or unipolar. In the bipolar mode (default setting), input voltages up to ±5 VDC can be applied (on the ×1 gain range). In the unipolar mode, positive voltages up to 10 VDC may be applied (×1 gain range). Refer to the table below for gain, range, and mode relations.
Time Base Selection (JP5) JP5 is a 2×3 header that allows you to apply 1 of 3 oscillatorderived frequencies to the 8254 timer chip. The frequencies are 100 kHz, 1 MHz, and 10 MHz. The default setting is 1 MHz. Note: A special-version 8254 timer-chip is required for 10 MHz. DaqView and most 3rd party software assume the 1 MHz time base. JP5 Time Base Settings Watchdog Timer Enable/Disable (JP6) This 3-pin header (JP6) allows the elective use of the watchdog timer.
AC Power Source AC Power Adapter Printer Optional Computer CA-35-2 Power Switch + GND +V Power Input Connector DaqBook DaqBook Connections To verify connections, turn ON the power switch by flipping the rocker- switch to the “1” position, and the POWER LED should light up. If using a printer, check operation by issuing a or equivalent command. Note: Software installation is necessary before the DaqBook can perform any functions.

A. Use the DBK Power Requirements Worktable to calculate the power requirements of your system’s DBK cards. B. Use the Available Power Chart to determine your system’s power availability. C. If the required power in step 5A is more than the available power in step 5B, you need an additional power card. There are two auxiliary power supply cards: • DBK32A – For use with a LogBook, DaqBook, or DaqBoard. It supplies ±15 V. • DBK33 – For use with a Log Book, DaqBook, DaqBoard, or Daq PC-Card.
11 – Connect internal signals Connect signal inputs from DBK cards to termination panels. DBK cards connect to the termination panels in various ways (see the following figure). Refer to the DBK options manual (p/n 457-0905) as needed. • Single-ended connections use analog common. • Differential connections require the proper polarity, typically red-to-red for high (+) and black-to-black for low (-).
Stacking Hardware Using Dual-Lock Tabs and Splice Plates For systems that make use of several data acquisition modules, stacking units together conserves space and simplifies cable runs. Such stacking can be facilitated with dual-lock tabs or splice palates. • Dual-lock tabs. Dual-lock tabs, often referred to as Velcro,® provide a means of temporarily stacking modules together. The tabs provide a convenient way to quickly add modules to [or remove modules from] a system.
Using T-Cables CAUTION Turn power OFF to the Daq devices and externally connected equipment while connecting cables and setting configuration jumpers and switches or before opening the lid. Electrical shock or damage to equipment can result even under low-voltage conditions. T-Cables are available in different lengths and can be used for linking two or more compatible devices together via the device’s 37-pin digital I/O connectors.

Expansion and Terminal Panel Connection DBKs The following DBKs offer provide various expansion and connection options. The stackable 3-slot DBK10 low-profile enclosure can be used for up to three DBKs. If a system has more than 3 DBKs, the 10-slot DBK41 can be used. Several DBK41s can be daisy-chained to accommodate many DBKs in one system.
1. The end use of the acquisition data should be used to determine how you set up and program your acquisition system. Prior to creating the system you should understand its layout and know how you are going to assign the channels. If you can answer the following questions you are off to a good start. If not, you need to find the answers. • • • • • What engineering units, ranges, sampling rates, etc.
15. If you are considering system expansion, review the DBK10, DBK41, and DBK60 document modules. The best option depends on the number of DBK cards in your system. For just a few cards, use the stackable 3-slot DBK10 low-profile expansion enclosure. For more than six cards, use the 10-slot DBK41. DBK41s can be daisy-chained to one-another to handle a large number of DBKs. 16. In regard to power management, you should review the DBK30A, DBK32A, and DBK33 document modules.
The DIN5 is the system’s basic power connector (see the following figure). The CA-115 is a 6-in. cable with a plug (male) DIN5 connector on both ends. The CA-115 is used to connect DBK32As [or DBK33s] in parallel when they are to be powered by the same power supply.
DBK32A - provides ±15 VDC @ 500 mA. DBK33 - provides ±15 VDC @ 250 mA and +5 VDC @ 1000 mA. The DBK32A and DBK33 power cards attach directly to the P1 analog expansion bus where they supply power to DBK analog expansion cards. The DBK32A and the DBK33 can be powered from an included AC adapter, an optional DBK30A battery module, or from a +10 to +20 VDC source such as a car battery.
Calculating Your System’s Power Needs Use the chart below and the worktable on the next page to ensure your system will have sufficient power. If the load (calculated in the worktable) exceeds available power (from the chart at the right), you must add a power card or a module such as a DBK32A or DBK33.
