USR-TCP232-304
1-port RS485 to Ethernet Converters
1-port RS485 to Ethernet converters USR-TCP232-304 can transmit data transparently between TCP/IP and RS485. RS485 to Ethernet converters USR-TCP232-304 are widespread required in industrial automation. Simple configuration and easy to use.
Ordering Guide
Serial to Ethernet,
Bidirectional Transparent Data Transmission
One More Thing, Modbus Gateway
Connect to PLC, SCADA system or user’s
private server to achieve local or remote motoring.
Multi-Host Modbus Polling
Modbus RTU to Modbus TCP
Multiple User Scenarios
Multi-user Access
Multi-device Management
Virtual-COM Software
This feature can infinitely extend the serial cable,
allowing communication to no longer
be limited by distance.
Point-to-Point Communication
Using this method, it is possible to achieve
data communication between two serial devices.
Additional Features
Heartbeat Packet
Server can detect abnormal disconnection from the client
using this feature (304 as an TCP client)
Customized RFC2217
Users can dynamically modify the baud rate, stop bit,
data bits and parity bits of the TCP232-304 by sending
PUSR customized protocol over the network.
Registration Packet
The server can identify different clients by using
registration packets.
High Reliability Design
Applications
Intelligent Transportation
By connecting the traffic lights to serial device server, the control center can collect and process traffic data on-site through Ethernet,
and the collected data can also provide accurate quantitative basis for traffic command and dispatch and city traffic rules.
Unattended Weighing
Connecting the serial server to the gate, it is convenient for the control center to remotely control the gate switch through Ethernet.
Multiple serial servers can be used to connect other serial cameras, weighing instruments, LED displays, FID card readers,
vehicle induction coils, ticket printers and other peripherals, enriching more application scenarios.
