The ports of a device are displayed at the bottom of the device. If a port is blue, it is an RS-485 port. If a port is 
green, it is an Ethernet port. The port number assigned to a port of a device is consistent with the definition of 
the port. For example, E1 represents the first Ethernet port, C1 represents COM1, and C2 represents COM2. 
The ports of an AH10SCM series module are marked with TR1 and TR2, and the ports of an AH10EN series 
module are marked with X1 and X2. Besides, if the IP address assigned to an Ethernet port is a dynamic IP 
address, or a port of an AH10SCM series module is not a Modbus port, the Ethernet port or the port of the 
AH10SCN series module will be gray, and can not connect to any network.
