Function Structure
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.
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.
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.
httpsD Client
Modbus Serial to IP converters USR-N540 support serial data transmitted to designed server in httpsD way.
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
Virtual Com Software
Special function
Synchronized baud rate
Change the baud rate, data bit, check bit
and stop bit dynamically via network commitment
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.
Modbus Serial to IP converters USR-N540 Support modbus gateway
More function
Customize webpage, Synchronized baud rate,
net printing, registration package, cloud
