Powering Up the Turret While On Ground
1. Make sure the aircraft is supplying power to the turret systems.
2. From the Hand Controller, lift up on the POWER switch and push forward.
3. The turret will cycle steering positions and return to the STOW position.
Note: After system power up and the IR cooling message is no longer displayed, the focal panel array continues to
stabilize after it has been cooled to operating temperature. Performing periodic 1-Point calibrations,
specifically 5 minutes after the cooling message, will help optimize the IR video imagery.
1.1.2 Communications
The system uses digital controls, including those for the turret. All operational communications are through RS-422
links. Control functions are distributed amongst multiple microprocessors.
1.1.3 Video Switch Matrix
A video switch matrix manages analog video inputs from all imaging sensors. The video switch matrix also
manages routing of all analog video outputs. Prior to output to an external display, the switch matrix applies
graphical overlay annotations to the sensor video. The MX-15i features an 8x8 S-Video matrix with:
• 3 overlay annotation layers (one for each imaging sensor)
• 4 video outputs
Operators can enable or disable display of the overlay in the video output
