I'll start here but may need to move to industrial control.
I have a temp chamber that is controlled by a Watlow F4 controller from software using a standard RS-232 3 pin DB9 connection. I can control this from within LabVIEW.
I need to be able to connect this temp chamber to a computer that has a software package which also communicates through a RS-232 to RS-485 interpreter. Since the output of this computer only works with it's prescribed settings (ie: 4800 bps, versus 9600 on my existing temp chamber) I need to monitor the output and be able to intercept the command output within LabVIEW, interpret the command and then send the appropriate command to the temp chamber controller as well as reply to the software so that it "sees" my non-compliant temp chamber and thinks it is the correct one.
Can anyone tell me the best way to enact a SPY routine to be able to view the command output? I have two PC's that I can use (one to run the control software and one to sniff the commands) and I know the command structure of the temp chamber it thinks it is talking to, so that shouldn't be problem.
Thank you.
