SAMPLE BUS CONTROL PROGRAM
The following is a brief note on how to configure a National Instruments GPIB-PC controller
card when used with the 6530. A program outline is provided that collects data using the
National Instruments GPIB-PC interface.
Assuming that the National Instrument driver has been installed with all the default naming, the
device name for ADDRESS 4 will be "DEV4", and could be used to control the 6530.
The "DEV4" should be configured as follows:
-
Default device name:
DEV4
-
GPIB address (fixed):
4
-
Secondary address:
none
-
Timeout setting:
3 seconds
-
Serial poll timeout:
3 seconds
-
Terminate read on EOS:
YES
-
Set EOI with EOS on write:
YES
-
Type of compare on EOS:
7 bit
-
EOS byte:
0A hex
-
Send EOI at end of writes:
YES
-
Enable repeat addressing:
YES
-
