3. External Connection

COM-1(PM), COM-1D(PM)

In the case of COM-1D(PM)

The figures below show examples of how to connect the cable for the PC card.

The RS-422A/485 interface works based on a differential signal whereby the signal is carried by the

potential difference between two lines (+ and -). Using twisted pair cable is recommended to improve

resistance to noise.
