Folding Mirror System Controls 

The folding mirror system requires signals from 2 separate switches. The mirror select switch must be in the neutral/fold position and the mirror direction switch must be activated to the left/extend or right/retract positions. Both switches are integrated into the DDS and provide direct signals.

Folding Mirror System Operation 

Upon receipt of the required switch inputs the DDS will supply battery voltage and ground to the mirror fold motor control circuits to perform the requested extend or retract function. The DDS will also send a LAN message to the PDS indicating the requested function. The PDS will supply battery voltage and ground to the mirror fold motor control circuits to perform the requested extend or retract function.
