Function Structure of modbus rs485 to ethernet converter, convertidor serial a ethernet/

Function Structure

Work mode of USR-N540, modbus rs485 to ethernet converter/converter serial to ethernet/: TCP Server

Work mode

TCP Server

Serial to IP converters USR-N540 listen on the setting port
and waits for a TCP client connection.
The data which the serial ports sent out transparently
transmit to all connected client via Serial to IP converters N540.

Work mode of USR-N540, converter rs232 to ethernet: TCP client mode

TCP client mode

Serial to IP converters USR-N540 initiate a TCP lint to the set IP address.
If the connection fails, USR-N540 will keep trying to reconnect until it succeeds.
Once the link is successful, the data will be transparently
transmitted between PC and serial device in bi-directional.

Work mode of USR-N540, 4 serial ports serial to IP Converter: UDP mode

UDP mode

Serial to IP converters USR-N540 sent the data to designated IP /Port.
If the connection fails, USR-N540 will keep trying to reconnect until it succeeds.
Meanwhile, USR-N540 listens the port and forwards
all data received to serial device.

Work mode of USR-N540, 4 serial ports serial to IP Converter: httpsD Client

httpsD Client

Modbus Serial to IP converters USR-N540 support serial data transmitted to designed server in httpsD way.

Work mode of USR-N540, 4 serial ports serial to IP Converter : WebSocket

WebSocket

Support WebSocket Sever,
Built Websocket link with devices by Websocket of webpage HTML5
Data transmission between built-in webpage and serial port in bi-directional
Custom webpage and websocket are acceptable
Achieves the functions of displaying data in real-time

USR-N540, 4 serial ports serial to IP Converter: Special function

Special function

Synchronized baud rate

Change the baud rate, data bit, check bit
and stop bit dynamically via network commitment

USR-N540, 4 serial ports serial to IP Converter: Serial Port/ Network heartbeat package

Serial Port/ Network heartbeat package

Network heartbeat package: Serial to IP converters USR-N540 notify the server
that it is active by sending Heartbeat Package regularly,
and maintain normal network links with the server.
Serial Port heartbeat package: The servers notify the serial device
that it is active, and the user can also actively grab the sensor data.

USR-N540, 4 serial ports serial to IP Converter: Support modbus gateway
