Hello! I have an issue I hope the experts here can help me with. I've been working on connecting a Baumer PCD41 process display to my laptop via an RS232 3 wire connection (ground, TxD, RxD) but I can't seem to get it to work correctly and I think it's one of three issues. I was hoping I could get some feedback on these.
The first issue, Baumer technical support could not tell me whether the process display was a DCE or DTE device, which is necessary for wiring TxD and RxD correctly. I would assume that a process display/PLC would generally be considered a DTE device, is that correct?
The second issue, which I think is my problem, is finding a good software program for reading the data input. Does anyone have a good software program they recommend for data input?
The third issue is configuring the ports on the computer. I know the process display is putting out the following signal: 4800 Baud, 1 stop bit, even parity, I am not sure on the flow control but I assume there is none, and I'm not sure on the data-bit rate, but I'm assuming it's 8 bit. Do those sound right and do I need to go into the control panel in windows xp and configure the serial port to match the settings for the process display?
Thanks,
Nick
