Moxa CP114EL-I Serial line adapter
The Processor Unit is equipped with a Moxa CP114EL-I serial adapter board. The board
provides four serial lines. The serial lines are connected using a large D-connector on the
rear side of the Processor Unit cabinet.
The Moxa CP114EL-I serial adapter supports RS-232,
RS-422 and RS-485 (both 2 and 4-wire).
The connections to the board are made using a
converter cable with four 9-pin male D-connectors.
The converter cable is supplied with the Processor Unit.

shipyard.
Important
When you are using RS-232 serial communication, observe that long runs of unshielded
cable will pick up noise easily. This is because the RS-232 signals are not balanced.
Maximum length for an RS-232 serial cable is typically 60 meters with 2400 bps data
rate, however this depends on the cable quality. Always check the cable manufacturers
specifications for the actual "shunt capacitance". A common figure is 47.5 pF/m, which
gives a maximum cable length of about 50 meters.
