Hello,
I am trying to control a HL5500PC Hall Measurement system. It is currently controlled by its (very old) software and uses GPIB and RS232. I want to be able to see what GPIB commands the software is sending so I can emulate it. I have never used LabVIEW or GPIB before.
I have connected a GPIB-USB-HS cable to the machine. In the screenshot you can see that the instrument shows up as 14 separate instruments. Is this supposed to happen? Also when I send the *IDN? query it gives an error. I am doing this with the machine turned on and both with and without its software running:
I have also attached the manual. Relevant GPIB information is located on page 63. It says the machine has a "listener" and "talker" mode. The 14 instruments listed in NI MAX have secondary addresses corresponding to the 14 different commands in "listener" mode. What is "listener" and "talker" mode? How can I switch between them?
In general, how can I communicate with this machine? The manual says you call functions by using the primary and secondary addresses. How would I do this in LabVIEW?
Finally, how does the RS232 connection play into all of this? Do I use LabVIEW to see/send RS232 commands as well?
Thanks!
