dear all
Right now my ML1200 is connected pc using pm02 cable. The driver used in PLC is Half duplex slave with 9600 baud rate which is requird for Citect scada.
Now i want to shift my PC to 125 Mtrs away.
is it possible by using net aic at both end?
How to configure in Linx?
Thanks.

past 50 feet on an Rs 232 is still possible however it will not get the max speeds this may be possible at 9600 baud for this distance if its not you will have to use an RS 485 circuit
