B1-CM25E/B1-CM55E   永宏模块   深圳销售点

○ 1 Ethernet connector : Standard RJ-45 Ethernet connector. ○ 2 Port2 connector : For RS485 signal. ○ 3 Port1 connector : For RS485 signal (B1-CM55E) and RS232 signal (B1-CM25E). ○ 4 Ethernet status indicator : LINK : ON indicates that normal connection. RX : ON indicates that the module senses messages in the Ethernet. TX : ON indicates that the module is sending messages to the Ethernet. ○ 5 Port2 status indicator : RX : ON indicates that Port 2 is receiving messages. TX : ON indicates that the Port 2 is sending messages. ○ 6 Port2 terminating resistor switch : This switch is used to enable/disable the Port2 RS485 terminating resistor. T means the terminating resistor is activated. N means the terminating resistor is not activated. ○ 7 Port1 status indicator : RX : ON indicates that Port 1 is receiving messages. TX : ON indicates that the Port 1 is sending messages. ○ 8 Port1 terminating resistor switch : This switch is used to enable/disable the Port1 RS485 terminating resistor. T means the terminating resistor is activated. N means the terminating resistor is not activated. ○ 9 Module status indicator (RUN) : Quick flashing indicates normal operation. Slow flashing indicates active setup.
