SYMPTOMS CAUSE / CORRECTIVE ACTIONS
• CP-2500 - Normal operation.
• Lamps - Normal operation.
• No traffic or weather information
is being displayed on the PED
over WI-FI.
1. Verify WI-FI module is receiving data from the Unit. For
example, on the RN-370M models, this is indicated from
visually seeing the blue flashing light on the unit. If indicator
light is not flashing, verify WI-FI is configured properly in the
DCM settings. Also, verify the device has power (batteries)
and that the connections between the WI-FI module and
the Unit are correct.
2. If WI-FI module is indicating it is receiving data, verify that
the PED WI-FI connection is configured to receive the
correct device name. (I.E. "WI-FLY-100").
3. Verify PED App is compatible with the Unit.
4. Verify the configuration setting for the PED App being used.
5. Replacement of the Unit may be required. Contact ACSS
Field Service before removal of the unit.
• CP-2500 - Normal operation.
• Lamps - Normal operation.
• FIS-B weather (such as
METARS, NEXRAD, CONUS
Data) is not being seen on the
weather displays.
Ground testing with the IFR-6000 can only simulate textural data
such as METARS.
1. When used in flight, the aircraft must be within range of a
ground station
NEXRAD information is only transmitted every 5 minutes,
and CONUS information is only available from certain
ground stations, and is only transmitted every 15 minutes.
• Cannot connect to the Unit with
the MPC/MAT tool.
• Lamps - Normal operation.
• CP-2500 - Normal operation.
• Displays - Normal operation.
1. Verify that the Lynx NGT-9000R is on ground. It is only
possible to connect to the maintenance mode for the first 2
minutes after power on if the unit is "in-air".
2. The USB connection to the unit requires special drivers that
must be installed on the MPC being used (see the general
information section for details). If that has been successfully
accomplished, replacement of the Unit may be required.
Contact ACSS Field Service before removal of the unit.
2. Verify that the MAT being used is compatible with the
software in the Unit being serviced. Contact ACSS Field
service for more information.
• XPDR FAIL is displayed on the
CP-2500.
• If installed, ADS-B Fail lamp is
OFF.
The transponder function of the Lynx NGT-9000R has failed or
is not communicating with the CP-2500.
1. At next power cycle if symptoms persist, contact ACSS
Field Service before removal of the unit or other equipment.
• TAWS FAIL is displayed on the
CP-2500.
Release 2.0 or later
The TAWS function of the Lynx NGT-9000R has failed or is not
communicating with the CP-2500.
1. One of the following failure(s) has been detected:
• GPS Fail
• Terrain (71DC) or Airport (68DC) Database
compatibility failure.
2. Reload Database (71DC) and (68DC) using the MPC
(MAT).
3. If the problem continues, replacement of the unit may be
required. Contact ACSS Field Service before removal.
• Any of the following messages
displayed on the CP-2500:
• GPS FAIL
• TAWS UNAVAILABLE
• ADS-B IN UNAVAIL - POS
Release 2.0 or later
An insufficient quality to the GPS position.
1. The GPS may be acquiring a signal. The GPS may need up
to 4 minutes to provide position
2. The GPS signal may be weak. Move the aircraft into an area
where the unit can receive a better GPS signal.
3. Cycle power to the NGT-9000R and the CP-2500.
4. If the problem continues, replacement of the unit may be
required. Contact ACSS Field Service before removal.
