RS485-to-Ethernet gateway for device networking

The USR-TCP232-304 converts serial RS485 data to TCP/IP Ethernet for transparent bidirectional transmission. It targets engineers integrating legacy RS485 equipment into IP networks. The module replaces the older USR-TCP232-204 and suits industrial automation, remote monitoring and equipment networking projects. Configuration is handled through a built-in webpage or serial commands.

10/100 Mbps Ethernet and 600-230.4 Kbps serial

The RJ45 port operates at 10 or 100 Mbps with Auto-MDI/MDIX. Serial baud rates range from 600 bps to 230.4 Kbps with selectable parity options. Supported modes include TCP Server, TCP Client, UDP Server, UDP Client and HTTPD Client. DHCP and DNS simplify network integration, while heartbeat and registration packets maintain link reliability.

DIN-rail mounting and virtual COM software included

The compact module is designed for DIN-rail installation inside control cabinets. A single RJ45 connector and pluggable RS485 terminal block keep wiring tidy. Firmware upgrades are performed over the network without physical access. USR-VCOM virtual serial port software extends legacy Windows applications onto the network transparently.

商品問答

What is the difference between the USR-TCP232-304 and the older USR-TCP232-204?

The USR-TCP232-304 replaces the older 204 model as a low-cost serial device server for bidirectional transparent transmission between RS485 and Ethernet with integrated TCP/IP protocol.

What does the 10/100Mbps Ethernet port mean for real-world throughput?

The RJ45 port supports 10/100Mbps with Auto-MDI/MDIX, capping wired network speed at 100Mbps for transparent data transmission between serial and Ethernet.

Which serial baud rates and parity options does the RS485 interface support?

The serial port operates from 600 bps to 230.4 Kbps with parity options of None, Odd, Even, Mark and Space for flexible device integration.
