Connection
RS-232 and RS-485
Note:
The wiring of the RS-232 must be laid separately from the power cables
and the control wiring in 110/220V.
NOTE!
You can not use RS-232 and RS-485 simultaneously.

Notes:
LINE TERMINATION: connect the termination resistors at the ends of
the line.
LINE TERMINATION: include line termination (120 ) at the ends, and
only at the line ends.
GROUNDING OF THE CABLE SHIELD: connect the shielding to the
equipment frame (suitable grounding);
RECOMMENDED CABLE: for balanced shielding.
Ex.: AFS series, manufacturer KMP.
