How do I use the RS232 port on the PCI-1424?

I am developing using MS C and IMAQ v2.5.3.

Here is a link to a post that is very similar to your question:

There are 3 serial commands included in niiamq.h. They are imgSessionSerialFlush,imgSessionSerialRead,imgSessionSerialWrite. I recommend looking at the niimaq.h file to see how the calls are made. You can find this file in the following directory:

C:\Program Files\National Instruments\NI-IMAQ\Include

We have SU640KTSX-1.7RT and use NI PCIe-1430.

I do this in c. It does  compile and run  but does not change anything.

uInt32 L=13;

uInt32 timeout=1000;

error=imgSessionSerialWrite(sessionID, "AGC:ENABLE ON", &L, timeout);
