Aircraft Category; Squat Switch Source; Arinc Tis-A Output; Serial Tis-A Output - Honeywell BendixKing KT 74 Installation Manual

4.3.5 Aircraft Category

To assist ATC tracking of aircraft, an aircraft category can be transmitted by
Mode S transponders. Using the numeric buttons (6 and 7), select the
aircraft category that most closely matches the aircraft the transponder is
installed in. Press FUNC to accept and move to the next menu item.

4.3.6 Squat Switch Source

The squat switch input allows the transponder to automatically switch
between airborne and ground modes, and to automatically start and stop the
flight timer. The sense of the squat switch input can be selected using the
numeric buttons (6 and 7). Press FUNC to accept and move to the next
menu item.
If the squat switch input is not connected the "not connected" option must be
selected.

4.3.7 ARINC TIS-A Output

If the aircraft has a compatible display connected to the transponder, enable
the appropriate ARINC output using the numeric buttons (6 and 7).

4.3.8 Serial TIS-A Output

If the aircraft has a TIS-A compatible display connected to the transponder,
select the appropriate interface protocol using the numeric buttons (6 and 7).
On this menu you can select None, TIS-A Traffic 1, and TIS-A Traffic 2.
When connecting to the Bendixking KSN 765/770 or Garmin display, select
TIS-A Traffic 1
NOTE: TIS-A is a Mode S uplink service that is provided by some US approach
radars. TIS-A coverage is limited to the coverage areas of those radars;
there is no TIS-A provision outside the U.S.A.

4.3.9 GPS Input

If a GPS is connected for ADS-B position reporting, select the appropriate
interface protocol using the numeric buttons (6 and 7). Press FUNC to
accept and move to the next menu item.

4.3.10 GPS/TIS-A Line Speed

If a GPS input or TIS-A serial output has been configured, you should select
the appropriate line speed using the numeric buttons (6 and 7). Press FUNC
to accept and move to the next menu item.
Traffic displays using the Garmin protocol run at 9,600 bps. Panel mount
GPS units with Aviation format outputs generally also run at 9,600 bps, as do
Garmin and Trig ADS-B outputs. NMEA GPS units generally run at 4,800 or
9,600 bps. Freeflight 1201 and NexNav 3101 GPS receivers generally run at
19,200 bps. BendixKing GPS receivers run at 9,600 bps for legacy systems,
such as the KLN94, and 115200 for the high performance receiver in the
KSN 765/770.
