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.
Adapter
A dedicated adapter cable is provided with the MS70 delivery. It splits the large front mounted connector to four 9–pin D-connectors.
To make the individual connections easier, four 9-pin D-sub connectors with screw terminals, and a number of adapter nuts
for connection to the adapter cable, are also included in the delivery.
Serial line support
The Moxa CP114EL-I serial adapter supports the following interface formats:
|
• |
Port 1: RS-232 / RS-422 / RS-485 |
|
• |
Port 2: RS-232 / RS-422 / RS-485 |
|
• |
Port 3: RS-232 / RS-422 / RS-485 |
|
• |
Port 4: RS-232 / RS-422 / RS-485 |
A dedicated software utility in the device driver is used to set up the ports to match your requirements. For this reason,
there are neither jumpers nor DIP switches on the circuit board.
