Ethernet Serial Module

Ethernet Serial Module

The RFI-ESM enables Ethernet communication over a wide area data radio network.

The module transparently transfers all protocols at the Ethernet MAC layer including FTP and industry standard TCP/IP Modbus and DNP protocols.

Ethernet to Serial Module Features

  • IEEE 802.3 MAC layer operation for simple deployment
  • Transparently transfers all protocols above Ethernet
  • 10/100 BaseT Ethernet
  • LED and software diagnostics
 

Ethernet Bridge Application

The module can be used in small and large scale telemetry systems offering the convenience of Ethernet and the wide area coverage of traditional telemetry systems.

The RFI-ESM transparently moves data from end-to-end at speeds of up to 115 kbps and when used with RF Innovations data radio modems can transport Ethernet data up to 50 km*.

*Maximum practical point-to-point distance with line of sight and suitable antennas.

Ethernet Serial Network

Serial Device Server Application

The RFI-ESM can also be used as a serial device server to provide an RS232 interface on a TCP/IP port. This effectively allows connection of RS232 devices onto an Ethernet network. When used with RF Innovations radios existing Ethernet infrastructure can be utilized as a backbone to provide connectivity to remote RS232 devices.
