Use this procedure to check input and output signals. These procedures assume the following:
•
Power is being supplied to the aircraft and the unit.
•
The Lynx MAT is active on the MPC.
•
The MPC is connected to the unit via the USB interface
•
After configuration options and calibration procedures where completed, power has been cycled to
the unit.
•
The MPC and unit are communicating and the Lynx MAT has been restarted the unit in Maintenance
(no WiFi).

Discrete Inputs, Altitude, and Heading. An
example of this page is shown in Figure 3-15.
•
Review the information seen on the inputs page.
•
The True/False indication of the current state of the discrete (e.g. True for the squat on ground
means that the aircraft is on ground. A false would mean that the aircraft was not on the ground,
at least according to the discrete).
Note – When the audio mute discrete is grounded it is considered active (i.e. muted). The Audio
Mute Inactive indication shows “True” when this discrete is active (grounded).
•
The Overall Discretes Validity is an indication of the remaining discrete states. A “True”
indicating that these indications are valid. A “False” indication with red text indicates that the
input is not being detected by the unit and a problem exists. If a problem is noted do the
following.
o
Check the configuration setup options for correct settings.
o
Check the fault log (Info
Z
Fault Log) for issues.
o
Check wiring or equipment.
•
Compare the altitude and heading values to an outside source.
