DRS-DXE-1310 Data Exchange Engine with 1310nm Fiber I/O, DRS-DXE-NF Data Exchange Engine without Fiber I/O. One Data Exchange Engine (DXE) is required for every DRS Series M System. A second DXE may be added to any group for full data stream redundancy. Each DXE provides 8 Frame I/O Ports for connection with signal frames, MADI adapters or Cheetah Mux/Demux video cards, up to a group total of 512 inputs and 512 outputs. DXE frames are equipped with at least one PERC1000 Frame Controller device a second frame controller may be added for control redundancy. A second power supply may be added to any DXE frame for full power redundancy. The frame controller in each DXE communicates over a 10/100 Ethernet link adding a second frame controller creates an additional network device for control redundancy.
