and described at follow:
1 Ethernet connector: To meet the anti-vibration requirement of industrial
environment, instead of using regular RJ-45 connector but using Euro. 4 pin
plug connector.
2 port4 connector: The signals in this connector is RS485 level.
3 port3 connector: The signals in this connector can be RS232(CM25E) or
RS485(CM55E). This port is a general purpose communication port
4 Network indicators:
LINK: Lit, when the Ethernet cable is properly working.
RX: Lit, when detecting a signal activity of the Ethernet.
TX: Lit, when the module is sending a message into the Ethernet.
5 Serial port status indicators:
RX: Lit, when detecting a signal activity of the serial port.
TX: Lit, when the module is sending a message into the serial port.
