I am trying to build a LabVIEW program to communicate with an Inrad Autotracker III. However I am completely new to serial communication and have not been able to find good resources telling me how to do it. Based on what I've seen online, I think the following code should be able to at least communicate with my instrument, but the VISA read is never able to return a signal and usually just times out.
The manual for the instrument doesn't have alot of information in it but I've included pictures to be helpful.
Any help would be appreciated, because I am quite lost in figuring out how to communicate with this device.
