Product Description

Mport3101R series products mainly realize the data transmission between Ethernet and serial port (RS-232/RS-485). This series of products is based on the 32-bit ARM Cortex-M7 main control CPU to realize the function of one Ethernet interface and one serial port to communicate and exchange data. This series of products converts serial devices in the field of industrial automation to the communication format of the Ethernet network, so that RS-232/RS-485 devices that were previously unable to access the Internet can be easily and flexibly linked to the network.

Features and Benefits

-One 100M Ethernet RJ45 port and one RS232/RS485 serial port

-Using 32-bit Arm Cortex-M7 core CPU, up to nearly 400MHz frequency

-External independent hardware watchdog design to prevent crashes

-Lightning protection of Ethernet interface up to 6KV

-RS-232/RS-485 interface up to 2KV surge protection

-Provide industrial grade DC power supply DC5 ~ 36V input

-Support Modbus RTU/ASCII to Modbus TCP conversion

-Support VirtualCOM software management

-Din Rail installation
