My Ultima Labmaster optical power meter responds to write commands but times out on read commands. My question is can I write my own driver to access the GPIB card? Is there any template for this or sample code to start from?

You want to write your own drivers for your National Instruments PCI-GPIB interface? This cannot be done, and I am not sure if this will help your application.

Did you insert delays between the writes and reads  or slow down the baud rate as suggersted in the article you linked?

[Albert.Geven]

adapting the bustiming to 2 microseconds seems a better option than baudrates for a gpib interface.

You can do that in MAX in devices gpib settings.

Thanks for the correction 🙂

I meant bus timing, NOT baud rate!

Adding delays didn't help. I also tried the slowest bus timing and it still wouldn't respond. 

I decided to use the RS232 interface instead of GPIB. It works fine this way.

Thanks for the suggestions.
