G Mode
Question
After I write the programming message
"stat cs"
to the GPIB-232CT,
status is not returned. All I get is a carriage return followed by a linefeed
(<CR><LF>). Why don't I get status information?
Answer
Every programming message must be followed by a carriage return and/or
linefeed. In BASIC, you can build your string as follows:
"stat c s"+chr$(13)
Question
After I write the programming message
"stat c s"+chr$(13)
to the
GPIB-232CT in G mode, my system times out when I try to read status.
Why?
Answer
Have you addressed the GPIB-232CT to talk? To read responses to
programming messages you send to the GPIB-232CT, you must address the
GPIB-232CT to talk, using the address you selected on the configuration
switch and adding decimal 64 to it.
Question
Whenever I send a programming message to the GPIB-232CT, it seems as
if the GPIB-232CT never receives it. The GPIB-232CT is powered on and
its
READY
LED is on.
Answer
On U22, switch 1 must be on for G mode and switches 2 and 3 must be off.
If you must change these switch settings, be sure to power the GPIB-232CT
off and then power it on again. Check all of your cable connections.
