Getting started with the NI GPIB-485CT-A in serial mode

Primary Software: Driver Software>>NI-VISA
Primary Software Version: 1.1
Primary Software Fixed Version: N/A
Secondary Software: N/A
Hardware: GPIB>>External Controllers/Convertors>>GPIB-485CT-A

Problem:
I have configured my NI GPIB-485CT-A in serial mode. I have connected a GPIB device but am unable to communicate with this GPIB device. Can you please help?

Solution:
To communicate using the GPIB-485CT-A isn't as straight forward as using GPIB directly. In order to send the command *IDN? to a GPIB device with address 5, you will need to send the following command over the serial bus.

WRT\s5\r*IDN?\nRD\s#100\s5\n

Translated, this is Write <space> <device address> <enter> <command> <line feed> Read<space><#number of bytes><space> <address><line feed>

All you need to do is replace the <command> section with whatever command you would like to send. If you are expecting some response from the device only then the read part should follow.
