* In the OEM installations a single weather radar 453
bus enters the left MFD, passes through, and is
terminated (70 ohm) at the right MFD. For EGPWS
installations break the 453 radar bus between the
MFDs, install switching relays, and wire one relay to
each MFD. The right MFD connection is moved to
remove the 70 ohm termination at that MFD. To allow
proper radar termination when EGPWS is passing
through the relays, the radar picture bus has a 70 ohm
resistor (added externally).
