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-subminiature connectors. The converter cable is supplied with the Processor Unit.
Adapter
A dedicated adapter cable is provided with the CS90 delivery. The adapter splits the large circuit board connector to four 9-pin D-Subminiature connectors. To make the individual connections easier, 9-pin D-Subminiature connectors with screw terminals are included in the delivery. Nuts to establish firm connections are also provided.
