trouble communicating with GPIB-232CT-A

[theguyfromtheuofu]

I can not communicate with my GPIB-232CT-A. I can send commands over the serial port, but I can't even get a light on the GPIB-232CT-A (except power and ready) to turn on. From what I have been reading, a driver is not necessary in S mode which I'm using. Is there a way in Java to make the GPIB-232CT-A recognize that I am talking to it? I have a mac with os X so none of the ni drivers will help. I am considering writing my own driver, but I'm not really sure about the syntax. I would be happy if the GPIB-232CT-A even somewhat recognized anything I send it.

Hi,
You do not need NI-488.2 drivers to talk to the GPIB-232CT-A in S mode. This is because it is simply a serial instrument in this mode. Have you gotten the device to work at all in S mode? A good way to check this would be to use a Windows PC and use Hyperterminal to talk to the GPIB device. Refer to http://digital.ni.com/public.nsf/websearch/61BA0EE248FB0B328625660B0066858D?OpenDocument for more information on how you can do this. If you are not able to do this successfully, then we may have an issue with the hardware. Please try this and let us know if you have any problems. Hope this helps.

I used testpoint's rs232 capabilities on a pc to try to talk to an hp 4145, but there was no communication. I sent commands in the gpib-232ct-A manual such as clr 17, but the hp did nothing and none of the lights on the gpib-232ct-A went on (except power and ready). My pc won't really go on the internet to download hyperterminal so do you have any other suggestions?
