Application example for the serial Com-Server:

RS232 line driver from Bonn to Berlin


RS232 line driver

without any additional expenditures, directly over the existing network

When the revision board asked why there were several lease lines and dial-up lines between the location, in addition to the intranet, the technicians realized that every adapter was already connected to all other adapters across the entire company.

The details

In box-to-box mode, the existing network including all available WAN access ports is used as a transfer medium for communication by the serial terminal devices. Additional control PCs and special software is not needed, as two Com-Servers ensure a fixed TCP/IP connection of the terminal devices over the network.

Typical applications

  • Replacement of out-dated serial star networks - e.g. in mid-range systems

  • Serial connections across long distances: A Com-Server pair replaces two line drivers or modems and offers disruption-free transfer due to TCP.

  • Implementation of serial connections with frequently changing locations without additional expenditure for cabling.
