DEX 500

​The Dellner Ethernet ConneXion Modem
  • DEX 500 modem in practice
  • Scheme for the installation of a Dellner DEX 500 modem in a passenger train

The Dellner Ethernet ConneXion DEX modems are a cost-effective way to use existing low frequency UIC train or spare lines to transmit network data across the couplers. This allows the use of video technology, infotainment, control terminals, passenger counting, LCD / TFT displays, wireless modules, etc. It works with older-technology contacts and even oxidized or dirty coupling contacts will not disrupt transmission. No coupler modification required.  

The DEX500 module is designed for mounting inside the rail vehicles. By converting the network data into a high frequency signal and overlaying it on top of existing signals across the coupler, the DEX modems can extend the network onto the coupled cars and throughout the consist. 

Product Advantages
