CHAPTER 2 INSTALLATION 11
2.3.3. Function Check
Confirm proper operation by connecting an IEEE-488 instrument to the bus and
attempting to operate it with a demo program written in Pascal.
Here is an example that uses an HP3478A digital voltmeter and a short Pascal
program. If an HP3478A is not available and you have p~another IEEE-488 instru-
ment, you need to modify the instrument programming code in the program source.
The program files MSP DEMO.EXE and TBP_DEMO.PAS are in the diskette
attached with this package. The source code of these demo programs are listed after
the test steps.
1. Connect the HP3478A DVM to the IEEE-488 bus connector of this card on the
back of the PC with a standard IEEE-488 cable. On the PCL-848B, the connector is
25 pin D type defined by IEC-625 and a PCL-15488-2 IEC-625 to IEEE-488 cable
must be used.
2. Set the device address of the HP3478A DVM to 23.
3. Turn on the HP3478A DVM and the PC.
4. Put the Demo/Library diskette into drive a:.
5. For Microsoft Pascal: Execute the program MSP DEMO.EXE by typing in
A:MSP_DEMO <return> For Turbo Pascal: Enter the Turbo Pascal and load the
source file TBP_DEMO.PAS. Press ‘R’ to run this program.
6. The CRT will display the 10 readings measured by the HP3478A DVM and thus
confirm proper operation.
If the system fails this test, check for these common problems:
