How far can DCC operate?
If you are asking this question, I am concerned the computers will be in different rooms. be sure there is no current flow between the grounds of your computers! This is especially previalent in industrial/office locations. A small voltage of 5vAC can be in current levels in excess of 10amps. Since the grounds between computers are not fused, the possibility of fire exists. Serial connections can operate in excess of 50meters, parallel 20. This will depend upon the type of wire, and electrical noise. Do not use sheilded wire, and keep the gauge relatively small to avoid capacitance.
