Setting up Newport 1830-C with GPIB

[jh143746]

Hi, I'm trying to connect the Newport 1830-C optical power meter up with Labview via a GPIB controller. I can successfully use the GPIB controller and cable with a different power meter but when I try to use it with the Newport I get an error. I've tried using NI-MAX and the device is there. If I go to the device and click "Open visa test panel" I often get the error:

Error opening resource:
ASRL3::INSTR

VISA: (Hex 0xBFFF0072) The resource is valid, but VISA cannot currently access it. Sometimes I can get onto the visa test panel - then if I go to input/output and click write, there is no error, but as soon as I click any of the options that require a response I get a timeout error. What could be the problem with this?

Hi

You are writing about gpib but using a serial connection (aslr means asynchronous serial line). Which one of the two is true.

Well I have connected a GPIB-USB controller with a USB cable to my PC and this is the name of the detected device so I'm not too sure.
