4-port Serial to Ethernet Converters USR-N540
Basic Function of 4-port Serial to IP Converters
Industrial solution ST cortex-H7:
4 Ports Serial to IP Converters USR-N540
Electrostatic protection ESD
Air: ±15KV
Contact: ±8KV
Electrical fast pulse train-EFT
Anti-surge: 4KV (8/20us)
Pulse group: 1.5KV 100KHZ
Watch dog
Hardware watchdog design, never crash in 24 hours.
Serial to IP converters USR-N540
Each one can work as RS232, RS485, RS422
Baud rate: 600bps~230.4Kbps
Hardware flow control: RTS/CTS
Software flow control: XON/XOFF
A flexible packet of serial data
Serial Port Switching Among RS232/RS485/RS422
Works at RS232 port by default. Use the converter plate for RS422 or RS485 and select the port via webpage, setup software, or dial switch mode.
Power supply supports Anti-reverse
Wide voltage: 5~36V
TCP Server
Listens on set port, transmits data from serial to all connected TCP clients.
TCP Client
Initiates TCP connection to set IP. Reconnects if failed, supports bi-directional data transmission.
UDP Mode
Sends data to set IP/Port, retries connection if failed. Forwards all received data to serial port.
httpsD Client
Supports HTTPS data upload to server.
WebSocket
Supports WebSocket Server for real-time data display.
Bi-directional communication via HTML5 WebSocket.
Supports custom webpage and WebSocket.
Synchronized Baud Rate
Dynamically update baud rate and data format via network commands.
Serial Port/ Network Heartbeat
Network heartbeat: Notify server USR-N540 is active.
Serial heartbeat: Server pings device, supports active sensor data fetch.
Modbus Serial to IP converters support Modbus Gateway
More Functions
Custom webpage, synchronized baud, net printing, registration, cloud.
Application: Unattended Weighing
USR-N540 connects to gateway and control center via Ethernet.
Controls devices like license plate camera, weighing instrument, LED display, card reader, induction loop, and receipt printer.
