Re: communication through serial port

Are the relays controlled by a serial controller, or are you using the modem signals directly?

Re: communication through serial port

they are controlle by one ADAM module which is more likely a serial controller.

Re: communication through serial port

OK - the fastest way to get started is to check out the serial examples included in LabVIEW or online (the on-line ones are better). Basically all you need to do is call a VISA Configure Serial Port vi (with the VISA handle, port settings, etc.) and then a VISA Write to send the command.

Let me know if you run into problems with the examples.
