Functions to send commands and receive data from GPIB device

[flobauer]

Hello!
I'm a GPIB rookie and have a few questions:
For the GPIB devices I am using (FWBell 7030 Gaussmeter, Keithley 6514 Electrometer) are no instrument modules available (at least I can't find any).
How can I talk with these devices, using the IEEE488(.2) functions.
If I use these functions (i.e. Send / Receive), I allway get error messages and the devices don't redspond.
How do I address a device on the GPIB Bus?

Every idea is welcome, I need all the help I can get.
Thank you!

Hi there,

This sounds like a GPIB question more than a CVI question. I'd recommend you post this question to the GPIB forum for better results.

Cheers,

Does a Scan for Instruments work? http://www.ni.com/support/gpib/max/scan.htm. There are GPIB example programs under C:\Program Files\National Instruments\MeasurementStudio\CVI\samples\gpib\ you could try.

You could find a driver for this instrument at http://www.ni.com/devzone/idnet/default.htm . If it's not listed there, it leaves you with one of a couple options. First, I would like you to submit a request for this driver at:

http://zone.ni.com/idnet97.nsf/instrumentdriverrequest/
We develop drivers based on demand and popularity so the more requests we have for it, the greater the possibility that we will develop one. If you would like to try developing your own instrument driver (or modify the existing one), we have documentation, model instrument dr
ivers, and driver templates to help at :
http://www.ni.com/devzone/idnet/development.htm
We also have a syndicate of third party vendors that specialize in National Instruments' products and services. Some of the vendors specialize in driver development. I would suggest contacting one of the Alliance members at:

Hope this helps.
