In the field of serial communication, our portfolio contains single and multi-channel AC telegraphy modems (FSK principle) for pointto- point, point-to-multipoint and multi-drop topologies with 2/4-wire connection for connecting remote control technology and meters
among other things or the remote connection of other terminals.
Managed and unmanaged switches are available for Ethernet communication. DSL technology and the tunneling ability of serial protocols make it possible to switch directly from serial voice frequency telegraphy (VFT) transfer to Ethernet communication while retaining the existing copper wires and without adapting the serial terminals, such as remote control technology. To increase the availability, functions such as the Rapid Spanning Tree Protocol (RSTP), redundant line communication (e.g. in an UMTS or Tetra modem) and the use of optical communication lines are available.
The individual communication products are available as DIN rail devices as well as plug-in modules for the rack. Extensive accessories of power supplies, various racks up to line transformers complete the communications solution.
