Where can I find PXI-6123 register definitions for register-based communication?

[gunnibaba]

Well, the subject line tells it all, I hope. I need to write a driver for the PXI-6123. I prefer a VISA driver because our data acquisition application is written in Java. I have already created an Open Source VISA wrapper in Java which can be found at jvisa.sourceforge.net. To write the PXI-6123 driver I need the relevant communication definitions. I don't even know whether the card supports registers or messages.

If I cannot come by this information, I guess I have to write a driver written in C using the DAQmx API and create a JNI wrapper around that driver.

Hi Gunnibaba,

Have you seen the NI Measurement and hardware DDK resources?

Based on the FAQ, it looks like there is an example for the NI-6133, which is in the same device family. You might want to start by looking at that:

Please note that this kit is supported on a separate forum by R&D only:

If you have any follow-up questions, please post them to that forum.
