Work mode
TCP Server
RS485 to Ethernet converters USR-TCP232-304 monitor the set port and wait for a TCP client connection.
Data from the serial device will transmit to all successfully-connected TCP clients via USR-TCP232-304.
TCP client mode
RS485 to Ethernet converters USR-TCP232-304 initiate TCP connection to the destination IP address that
configured by the user and USR-TCP232-304 continuously try to reconnect if establishing TCP connection
unsuccessfully. If USR-TCP232-304 establishes TCP connection to TCP Server successfully, it can realize
bidirectional data transparent transmission between TCP Server and the serial device.
UDP mode
RS485 to Ethernet converters USR-TCP232-304 will transmit serial data from serial
device to target network device by UDP connection. USR-TCP232-304 will listen to port
and transmit all received data to serial device.
HTTPD Client
RS485 to Ethernet converters USR-TCP232-304 support https Client mode which can transmit serial data
to the https server in https format(GET/POST).
Virtual Com Software
Powerful Virtual Serial Software USR-VCOM
Synchronous Baud Rate
Dynamically change baud rate, data bit, check bit and stop bit of USR-TCP232-304 via network command.
Identity packet function
When RS485 to Ethernet converter USR-TCP232-304 works as TCP Client, it can send identity packet to
TCP server which can be identification. Identity packet can be IMEI code,
ICCID code and user editable identity packet.
Serial & Network Heartbeat Packet
RS485 to Ethernet converters USR-TCP232-304 maintain the normal connection with the server by sending
heartbeat packet regularly.
USR Cloud
IoT cloud platform that is developed by our company independently. RS485 to Ethernet converters
USR-TCP232-304 support USR Cloud.
Application
[ Unattended Weighing ]
Connect USR-TCP232-304 to barrier gate and it can realize remote control of
barrier gate by Ethernet in control center.
[ Traffic Lights Management System ]
Connect RS485 to Ethernet converter USR-TCP232-304 and it can realize traffic data acquisition and
processing by Ethernet in control center. It can also provide accurate quantitative basis for
traffic dispatch management and urban transport planning Can implement the optimum control for
transportation phenomena such as traffic jam, traffic accident, traffic capacity from a regional
or global perspective.
