4.4.3 Remote Mount NGT-9000R
Use the following information for initial installations and debugging issues that may appear during
operation.
• An invalidity may not stop operation of the unit, but may degrade performance. Invalidities may self-
correct depending on the issue.
• Verify that the aircraft has a clear view of the sky for good GPS Operation.
A failure indicates a problem with the interface to the Remote Mount NGT-9000R or that a problem
exists with the Lynx MSS or one of the system components. If a "Fail" message (or No LRU response) is
observed cycle power to the Remote Mount NGT-9000R system. If the problem continues refer to Table
4-3 for possible cause and corrective actions. The symptoms listed are for all the possible equipment
installations. It is up to the user to identify their particular installation. Failures are typically observed via
messages displayed on the CP-2500 Control Panel or indicator lamps (ADS-B Fail) depending on the
particular installation.
A message being received by the CP-2500 from the Remote Mount NGT-9000R has priority over normal
display operation and is seen scrolling across the display. Rotating the large knob scrolls through unseen
messages and the normal display operation (showing operational mode and squawk code). The display
begins showing the highest priority message again after 10 seconds of no activity.
NOTE
The information listed in the Symptoms column encompass all the
possible issues that a technician may observe, but only some of the items
may actually be seen depending on model options and secondary
equipment being used.
A MPC connected to the USB port of the Remote Mount NGT-9000R is essential in troubleshooting.
Refer to paragraph 4.5.3.2 (list of fault log messages) and Table 4-4 for instructions on viewing fault logs
and using the service functions of the MPC (MAT). The information provided here should be in
conjunction with the information provided in Table 4-3.
It should be noted that the ADS-B Out Fail Lamp will be ON when the unit is in maintenance mode (via
the MPC (MAT)).
If the only corrective action left is to contact L 3 Field Service, then L 3 Field service personnel may
request that a file be created using the MPC that would provide them with information on the unit (i.e.
version, faults, and configuration). Create this file by going to the File menu of the MPC (MAT),
selecting Save, and placing the file in a location that can be easily located for transfer to L 3 Field
Service.
