Only approved devices may provide altitude to the GTX 32 in accordance with 14 CFR Part 91.217. In

addition, all altitude reporting devices installed in the aircraft must meet certification requirements of

14 CFR Part 91.413. The installer must select an altitude reporting device that is a certified altitude

source for the particular aircraft.

For additional information, refer to GNS 480 (CNX80) Installation Manual 560-0982-01 for the altitude

data reporting configuration.

Discrete Inputs/Outputs

Table 4-4. Discrete Input/Output Pin Assignments

Pin Name

EXTERNAL IDENT SELECT*

XPDR SYSTEM ID PROGRAM*

AIRBORNE SENSE (SQUAT SWITCH)

EXTERNAL SUPPRESSION (TXP/DME)

INACTIVE: 10 ≤ Vin ≤ 33VDC or Rin ≥100kΩ

ACTIVE: Vin ≤ 1.9VDC with ≥ 75 uA sink current, or Rin ≤ 375Ω

Sink current is internally limited to 200 uA max for a grounded input

EXTERNAL IDENT SELECT (remote IDENT) is a momentary input. Refer to Figures C-1, C-2, & C-3

for the remote IDENT switch interconnect.

AIRBORNE SENSE (SQUAT SWITCH) is an ON or OFF input. The squat switch is one of the

Airborne Determination methods available for sensing airborne status. Input for Airborne Determination

allows automatic start and stop of the flight timer and enables automatic STBY mode selection. Refer to

figures C-2 & C-3 for the squat switch interconnect.

XPDR SYSTEM ID PROGRAM* (remote STBY) is an ON or OFF input used typically for dual

transponder installations. When grounded, the GTX 32 is placed in standby.

EXTERNAL SUPPRESSION should be connected if a DME is installed in the aircraft avionics system.

The GTX 32 suppression I/O pulses may not be compatible with all models of DME. Known

incompatible units include the Bendix/King KN 62, KN 64 and KNS 80. These models have an output-

only suppression port and can be damaged by the GTX 32 mutual suppression output. In this case, leave

the suppression pin open. Refer to figures C1, C-2, & C-3 for the external suppression interconnect.
