2. INITIAL BOARD SETUP
2.1
1) Verify that all power supplies are off before making connections.
2) Connect a +5.0 VDC power supply to the +5V (J47) red binding post. Select VLS and VD operating voltage by
3) Connect a +12.0 to +18.0 VDC power supply to the +18V (J49) green binding post. If using the FILT position
4) Connect a -12.0 to -18.0 VDC power supply to the -18V (J50) yellow binding post. If using the FILT position
5) Connect the common ground of the power supplies to the GND (J48) binding post.
6) Attach parallel port cable between board and computer.
7) Attach all required analog and digital cables to the board jacks and connectors.
8) If using the DSP Header connection, attach the required user supplied flat ribbon cable to the header with the
9) If using the External Control Header connection, attach the required user supplied flat ribbon cable to the header
10) With all cables and connections in place, turn on the power supplies to the board. Turn on supplies in this order:
11) Press and release the RESET switch S1. The LED, D1, will illuminate as long as S1 is depressed indicating a
2.2
1) Create a directory called CDB42518 anywhere on your system.
2) Copy CDB425XX.EXE from the included CD into this directory.
3) Copy the .LVS preset script files from the CD into this directory.
4) Run port95nt.exe from the CD. This will install a utility that will allow the CDB software to access the parallel
5) If desired, create a shortcut to CDB425XX.EXE on your desktop. You should now be able to run
6) Select the LPT port you are using to connect to the CDB42518.
7) Shut down the application, reset the board, and then restart the application.
