Page 5-12 GTX 330 Installation Manual
Revision G 190-00207-02
ARINC 429 OUTPUT
The GTX 330 can be configured to include GPS, Airdata,
AHRS, EFIS/Airdata, and ADLP ARINC 429 inputs,
functioning as an ARINC 429 data concentrator. Refer to Section 4.6 SERIAL DATA ELECTRICAL
CHARACTERISTICS for details. The ARINC 429 OUTPUT Pages configure the ARINC 429 output
ports. Each port can be configured independently for the desired function(s). Both ARINC 429 outputs
send high speed ARINC 429 data.
SELECTION DESCRIPTION
CHANNEL 1 (DATA)
DATA SOURCE: OFF, ADLP, GARMIN or GARMIN W/TIS.
DEFAULTS to OFF. ARINC 429 input channel 4 sets the ARINC
429 output channel 1 to the same selection.
CHANNEL 2 (DATA)
DATA SOURCE: OFF, GARMIN or GARMIN W/TIS.
DEFAULTS to GARMIN W/TIS. (See Figure C-5, Note 2 for
description of Garmin format.) Do not select GARMIN W/TIS if
the aircraft contains another traffic detection system.
In aircraft having multiple traffic systems and multiple 400/500 Series units, configure ARINC 429
output CHANNEL 1 for GARMIN W/TIS and ARINC 429 output CHANNEL 2 for GARMIN. TIS is
then enabled over CHANNEL 1.
The Garmin format is a data concentration function. The following data is sent out at specified intervals
using high speed ARINC 429 (100 kHz). The transmit data labels and their rates are as follows:
