Connections (figure 2-1). Connections on the rear panel of the unit will cause the appropriate LEDs to illuminate
indicating those systems connected and working. These connections perform the following functions:
(1)
ACC 1-4
These connections facilitate the testing of the accelerometer cables for functionality. They are connected
to the simulated accelerometers inside the unit and to the appropriate connection on the DAU front panel.
(2)
UTD/EPT
This connection is provided for the UTD cable.
(3)
MAG SEN
This connection interfaces to a magnetic interrupt cable to provide the channel 1 TACHO input to the DAU
"TACH" connector.
(4)
TRKR 1, 2
Provides the test outputs for synchronizing an oscilloscope to the tracker signals.
(5)
TACH 1,2
These connections allow synchronization to the tachometer outputs.
