The front side of the FEP Backplane has connectors for the Front End boards (RELAY, GRX, GTX, DRX
and GFI), the Main Power Supply, the External I/O, the Fan Connector and a connector for the CW
probe signals.
On the rear side of the FEP Backplane, there is the FEP Backplane Connector with BSCAN signals,
GFI Audio, +5V (from GFI) and I
• Voltages are distributed from the Main Power Supply to the different boards.
• Control signals and Clocks are distributed from the GFI board to the other boards.
• Low amplitude analog signals from GRX board to DRX board.
• Data signals are routed from DRX board to GFI board.
• The BSCAN signals, GFI Audio, +5V (from GFI) and I
External I/O, depending on the BEP model in use.
The only active electronics on the FEP Backplane is a I
voltage regulator for the power supply to the I
In addition, there are termination resistors and power supply bypass capacitors.
