Miradore Posted April 6, 2005 Report Share Posted April 6, 2005 Does anyone know if it is possible to get LabView (ver 7.0) to look at the individual RS232 pins. I am wanting to detect a switch operation without the use of a DAQ card by monitoring the RTS or CTS line. I am not sending or receiving specific bytes of information. Just wanting to detect a voltage. Any assistance will be gratefully appreciated. Quote Link to comment
Mark Balla Posted April 12, 2005 Report Share Posted April 12, 2005 monitoring the RTS or CTS line. I am not sending or receiving specific bytes of information. Just wanting to detect a voltage. I needed to do this for a UI device that I built a tester for. the test code didn't use hardware hand shake lines but the customer application did. I found that if you use a property node on a serial visa reference it will give you control of the hardware lines. Hope this helps Quote Link to comment
