Does the gpib-232cv-a need the driver ? And how about the gpib-232ct-A?what is the difference !

Hi,

The GPIB-232CT-A has full GPIB controller capability. It has the ability to control GPIB systems similar to that of National Instruments plug-in controller boards.

The GPIB-232CV is only a protocol converter; it translates GPIB protocol to serial and vice-versa. This box has no GPIB controller functionality.

The CV does not require any driver to work. Details are in the manual. The CT uses the standard GPIB drivers.
Hope this helps out!

What are you trying to accomplish? Are you trying to add a GPIB instrument to a serial system or a serial instrument to a GPIB system? Both boxes work both ways. If you are trying to add a serial instrument to a GPIB system, neither of the boxes need a driver. If you are trying to add a GPIB instrument to a serial system, the CV-A does not need a driver, but the CT-A may or may not need a driver. If you wish to use the CT-A with NI-488.2 style calls, you can use a Win3.x driver and the compatibility release for Windows 9x. Alteratively, the box accepts serial commands and you could talk to it directly without a driver. It would not accept NI-488.2 style calls, but it would work just like a full GPIB controller.

The CT-A is more powerful than the CV-A. If you
are looking for an external solution for your PC, I recommend going with the GPIB-USB-B solution. It offers higher performance and is fully supported by the lastest versions of 32-bit NI-488.2.
