Hi Rory,

 

The synApps “ip” module has support for the Keithley 2001.

The important files are:

This implementation allows each channel on the plugin card to have a different function (volts, ohms, temperature, etc.).

 

The I/O uses asyn, and so it is independent of whether you use serial or GPIB.  I have tested both.  The newer versions of this meter (2700 series) have Ethernet, and that also works. 

 

Is there a reason you are using GPIB rather than RS-232?  I believe I found that GPIB was no faster, and it is considerably less convenient in most cases.

 

Let me know if you have questions.

Hello,

 

I am working as part of the IBEx project at ISIS in the UK.

 

I am looking to support the Keithley 2001 Digital Multimeter using a GPIB bus.

 

Has anyone created an IOC for this device?

 

Kind regards,
