Installation Manual for details.
Release 3.2 or later. The RS-232 Control Panel interface has a Reply Rate Feature (XPDR REPLY
message) available that is an indication that the transponder is active. Note – This is not available on
the CP-2500.
Release 3.2 or later. A Control Panel discrete switch (Discrete 5, P1-31) may be used to select
Control Panels in installations with dual ARINC 429 Control Panels. This function is detailed in the

3.2.2.4 Cockpit Switch and Status Lamps
The IDENT and Audio Acknowledge switch and status lamps are optional installations.
Pressing the remote IDENT switch activates the IDENT message to be sent by the unit via ADS-B
Out. An IDENT pulse highlights the aircraft’s symbol on the ATC’s radar screen and is identified on
the control panel when active.
Pressing the Audio Acknowledge cancels the audio from a TAWS or Traffic Aural. This function is
available with Release 2.0 and greater.
Placing the Standby Mode switch in the active position puts the transponder in Standby Mode. It will
remain in this mode unit the switch is placed in the inactive position. The active position also
overrides the CP-2500 Mode control. This function is available with Release 2.1 and greater.
The Traffic Alert lamp (amber) illuminates when:
o TAS/TCAS is enabled and there is a traffic alert condition (only possible when TAS/TCAS is
activated).
o TAS/TCAS is enabled and Self-test is run, the lamp will be "ON" for approx. 8-10 seconds.
o ATAS is enabled and there is a traffic alert condition (ATAS uses ADS-B In traffic data).
The ADS-B Out Fail lamp primarily indicates when the Lynx NGT-9000 is not providing ADS-B
output data. The lamp may be illuminated (ON) for any of the following reasons:
1. When Lynx NGT-9000 is not powered, lamp defaults to "ON".
2. When the aircraft is On-Ground and the self-test is run, the lamp is "ON" for approx. 8-10
seconds.
3. When the aircraft is On-Ground, the lamp is "ON" until the Lynx NGT-9000 has started and is
operational after which the lamp will extinguish.
4. When the GPS has "failed", the lamp is "ON". GPS failures happen when:
a. The Lynx NGT-9000 internal GPS indicates a failure.
b. Aircraft is On-Ground and the GPS has acquired position, but the signal is lost for more
than 2 minutes.
c. Aircraft is In-Air and the GPS has not acquired position within 2 minutes (either startup or
had position and lost it).
5. The lamp begins to flash for the following reasons:
a. Aircraft On-Ground, there is a 2 minute "quiet period" when the GPS is expected to
acquire position. After 2 minutes, the lamp will flash indefinitely while the GPS has never
acquired, but is not failed.
b. Aircraft In-Air, at startup or if GPS had position and then lost it, then the lamp will flash
for 2 minutes while trying to acquire position, then become failed (see 4.c. above).
The TAWS Caution lamp (amber) illuminates when a terrain caution advisory is present.
The TAWS Warning lamp (red) illuminates when a terrain warning advisory is present.
