TRP-C34 - Ethernet to 4 port RS-232/422/485 Serial Converter


The TRP-C34 is a fast 4-port serial to Ethernet converter. It is designed to convert serial data from any of 4 x RS-232 / RS422 / RS485 ports to a 10/100Mbps Ethernet network running using the TCP/IP protocol. This provides a straightforward method of connecting up to 4 x remote serial peripherals eg. sensors, serial printers etc to an Ethernet network and then allows data to be read from / sent to these remote peripherals by sending data from a single PC other the Ethernet network. Typical applications include remote monitoring of serial sensors / transducers in factory control systems.

The TRP-C34 device can be operated via Windows, Linux and UNIX without the need to modify existing software. The TRP-C34 is capable of operating in “Direct IP Mode”, “Virtual COM Mode”, and “Paired Mode” making it very versatile and suitable for most serial networking applications. It also offers a Heart Beat feature to ensure a reliable communicating connection. The TRP-C34 will work with 'Loop back Mode' where all data is sent back immediately. This feature makes the connection testing easy.

The industry standard DIN rail design enables fast and professional installation.

This product does NOT come with a serial cable or power supply. These items should be purchased separately.

Operating Modes

The TRP-38 supports the following methods of mapping 'Serial RS-232 Data' to 'Ethernet Data':

  • “Direct IP Mode” - a selected remote RS-232 port is mapped to a specified TCP/IP address
  • “Virtual COM Mode” - a individual 'Virtual COM Port (VCP) is created for each remote RS-232 port
  • “Paired Mode” - allows two TRP-38 devices to be paired together with one as a MASTER and the other as a SLAVE. No PC is then required.
