4. When configuring your LogBook or Daq device(s) consider the following:
•
LogBook calibration is typically performed automatically through LogView software;
however, some DBKs may require manual calibration.
•
The DaqBook/100 Series and DaqBook/200 Series devices, and DaqBoards (ISA type)
have internal jumpers and switches that you must set manually to match your
application.
•
Some DaqBook/100 Series and DaqBook/200 Series models are partially configured in
software.
•
DaqBook/2000 Series devices have no jumpers or internal switches and are configured
entirely through software.
•
Daq PC-Cards are configured entirely in software.
•
DaqBoard/2000 Series boards are PCI type boards. They have no jumpers or switches and
are configured entirely through software.
•
cPCI DaqBoard/2000c Series boards are compact PCI (cPCI) type boards. They have no
jumpers or switches and are configured entirely through software.
•
You may need to refer to other documentation, such as Quick Starts, Installation Guides,
User’s Manuals, and pertinent DBK document modules.
5. Perform all hardware configurations before connecting signal and power. Remember to
configure all the DBK cards and modules for your application. Several jumpers and DIP switches
may need to be set (channel, gain, filters, signal mode, etc).
6. Setting up channel parameters often requires both hardware and software setup.
7. Route and connect all signal and power cables while all power is turned OFF.
8. To minimize electrical noise, route all signal lines away from any RF or high-voltage devices.
9. Follow your device’s specific installation instructions. For certain devices software should be installed
first; for others, hardware should be installed prior to software installation.
10. After software is loaded, remember to set the software parameters as needed for your application.
The software must recognize all the hardware in the system. Measurement units and ranges
should be checked to verify that they meet your application requirements.
11. Remember to set all channels to the proper mode for your DBK or other signal source.
12. After your system is up and running, verify proper data acquisition and data storage.
13. Verify system accuracy; adjust ranges or calibrate as needed.
14. Device specific information regarding system setup and expansion can be found in the Daq and
LogBook User’s manuals; and in the applicable DBK document modules of this manual.
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. For portable applications, the compact DBK30A rechargeable power supply can provide
power to the DBK10 or DBK41. The DBK30A also includes a 28 V output for powering 4 to 20 mA
transducers. For applications with many DBK cards (initially or in future expansion), the DBK32A or
DBK33 can be installed into any expansion slot. The DBK32A provides ±15 VDC and the DBK33
provides ±15 VDC
and +5 VDC.
