Serial Port Switching Among RS232/RS485/RS422
Works at RS232 port by default Please use converter plat for RS422 or RS485 port and select corresponding port via webpage or setup software or manually adjust under dial switch mode
Work mode
TCP Server
Serial to IP converters ST-TCP540I 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 ST-TCP540i.
TCP client mode
Serial to IP converters ST-TCP540I initiate a TCP lint to the set IP address. If the connection fails, ST-TCP540I 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 ST-TCP540I sent the data to designated IP /Port. If the connection fails, ST-TCP540I will keep trying to reconnect until it succeeds. Meanwhile, ST-TCP540I listens the port and forwards all data received to serial device.
httpsD Client
Modbus Serial to IP converters ST-TCP540I support serial data transmitted to designed server in httpsD way.
WebSocket
Support WebSocket Sever, Built Websocket link with devices by Websocket of webpage HTML5Data 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.
Modbus Serial to IP converters ST-TCP540I
Support Modbus gateway
Application
Unattended Weighing
Modbus serial to IP converters ST-TCP540I connect to the gateway and the control center remotely controls the switch ON/OFF via Ethernet. Meanwhile, ST-TCP540I also support unified use of unattended weighing equipment like license plate snapshot serial port camera, weighing instrument, LED promoting screen, card reader, vehicle induction loop, receipt printer and so on.
