Hi all
im interfacing pc to trio motion controller through RS 232 but the problem i am facing is that the connection to controller is lost again and again due to EMI. can any one suggest how to protect RS 232 from EMI and RFI. Waiting for positve response Regards
Use fiber converters to provide ground isolation...
How do you know it's EMI ? RS-232 is kind of robust.
Serial data can usually be run for up to 150 feet over foiled twisted pair if the data rate is 9600 or below. It depends on a lot of factors. How long is the cable? What kind of cable is it? (single conductors or twisted pair) What speed are you running? (bit rate or baud rate) What kind of ground is on the equipment? The standard RS-232 cable is not twisted pair, so if you're using twisted pair, the problem may be caused by interference between transmit and receive.
