Comnet CNFE2DOE RS232/422/485 Data over Ethernet Terminal Server

The ComNet™ CNFE2DOE terminal server supports 2-channel bi-directional data transmission over 1 or 2 optical fibers. The server is universally compatible with RS232, RS422 and serial data protocols. All configurations are done through its web server. The CNFE2DOE has two serial ports that can be configured by communicating from one port to another through the network. Distances depend on which SFP (Small Form Pluggable) module is used. The RJ45 Ethernet connector is included and is automatically disabled if the optical interface is used. Open source com0com TCP/IP protocol is supported for any customer PC applications to communicate with terminal servers over the Ethernet. The software utility allows customers to search for the terminal servers installed on the same subnet, and create virtual com ports for each serial port on these servers. Individual serial ports running in client mode can be connected to a different serial port on a different terminal server running in server mode.
