Main Functionality

Modbus Gateway

The device supports the conversion of Modbus-RTU to Modbus-TCP.

Modbus gateway

Replace Multiple RS485 Bus

Support multiple masters and multiple slaves running at the same time, which can replace multiple RS485 buses.


Support Multi-Host Function

Under normal mode, when two hosts: host a and host B are connected to the serial port server at the same time, host A sends a command, the RS485 device receives②command, and the RS485 device returns ③ command, but the network port end of the serial port server will send ④ to host A and ⑤ to host B at the same time. Since host B did not send the query, but also received the response instruction, host B may generate abnormal communication errors. In the multi-host mode, there will be only instruction but not instruction, because the serial port server will automatically remember the host to be returned, and only return the instruction to the nearest communication host, host a query will only reply to a, and host B query will reply to host B.
