When it is finished, the following message appears on the screen:
Plotter test finished.
Please check output to plotter with user manual instructions.
If the plotter does not respond or the output on the plotter does not match Figure 4-1, check again
to be sure that all of the connections are tight and the jumpers are all set correctly. Try the test
again. If it still does not work, write down any error messages that appear and call National
Instruments.
-c change COM configuration
This command is used to change the base address of the GPIB-COM to match the actual board
settings. If you have changed the jumper settings to something different than the default settings,
you must run this command.
When this command is selected, the following menu appears:
This program assumes the GPIB-COM is configured at base address
3F8 (COM1).
Enter the number of the correct address.
1) base address 3F8 (COM1)
2) base address 2F8 (COM2)
Enter 1, 2, or <return> for no change?
Type in the number of the address that you have configured the board to. The computer prints out
your choice and returns to the main menu.
-q quit
This command ends the test program and returns to DOS.
