USR-M100-EAU 4G Server / Expansion Module Remote IO Expendable Edge Computing Gateway MQTT/SSL RS485/232/Ethernet Modbus RTU to TCP Json Modbus Polling

Features:
Serial port
The USR-M100 supports 2 serial ports, 1 RS232/485 and 1 RS485, and adopts Spring-type terminal. When connecting up Modbus devices via an RS485 network they should be daisy chained together, and a dual twisted pair cable are recommended.The connections should be kept the same throughout the network: positive to positive, and negative to negative. These may sometimes be labeled up as A and B. The maximum length of the serial network cannot exceed 1200m regardless of boosters and repeaters.

Ethernet RJ45 interface
The 10Base-T/100Base-TX adaptive Ethernet RJ45 interface supports automatic MDI/MDIX connection.
Link LED: green color. Lights(steady on) when the module is connected to a network.
Activity LED: orange color. Blinks when network data is transmitted through the port.

Quick test
USR-M100 has a built-in Web server, which provides a convenient way to access and configure the remote IO module. Users can use Edge , Firefox or Google browser to access it.
It is strongly recommended for the users to set the Network Parameters through configuration tool first. Other device-specific configurations can later be carried out via user-friendly Web-Interface.

Hardware connection
For fast networking of USR-M100 smart RTU, you need to prepare a PC, a router, a network cable, a serial cable, and a DC12V/1A power supply. To establish a TCP / IP network all devices must be connected to the same network either locally or via gateway connections.
