Page 10: Section 1 General Description
It receives ground radar and TCAS interrogations at 1030 MHz, and it transmits a coded response of pulses at 1090 MHz. The GTX 23 replies to Mode A, Mode C, and Mode S interrogations. Mode A replies consist of framing pulses and any one of 4,096 codes, which differ in the position and number of pulses transmitted. -
Page 11: Ads-B Capabilities
There are three distinct ADS-B versions recognized by regulatory authorities. As shown in the table below, the Garmin GTX 23 w/ES currently supports ADS-B Out 1090MHz Extended Squitter capability meeting ‘Version 1’ or ‘Version 2' ADS-B system requirements depending on software version (Table 1-1). -
Page 12: Tis System Capabilities
The TIS ground sensor uses real time track reports to generate traffic notification. Traffic display is available to aircraft equipped with a Mode S data link such as the Garmin GTX 23 transponder. Traffic can then be displayed on a Garmin GDU Primary Flight Display, or GNS 400W/ 500W-series unit. -

Page 21: Installation Considerations
Six feet of separation is a guideline. Radar altimeters (should one be installed on an aircraft with a GTX 23) also have some potential to receive interference from a transponder (the transponders’ fourth harmaonic), so it is good practice to separate transponder and radar altimeter antennas by as much as practical also. -
Page 22: Cabling And Wiring
The GTX 23 back-plate assembly utilizes a BNC-type (bayonet connection) coaxial connector. The maximum attenuation at 1090 MHz between the unit and the antenna must not exceed 1.5 dB. This loss specification includes connector loss;... -

Refer to Appendix B for Shield Block Installation Instructions. 3.5 Weight and Balance Weight and balance computation is required after the installation of the GTX 23. Follow the guidelines as established in AC 43.13-1B, Chapter 10, Section 2. Make appropriate entries in the equipment list indicating items added, removed or relocated along with the date accomplished. -
Page 28: Final Installation
3.8.1 Configuration Since the GTX 23 is remote mount, it is installed with other equipment that provides a user interface. For information on configuring the GTX 23, please see the installation manual for the equipment that provides the user interface for the GTX 23. The G3X install manual (190-01115-01) is an example of a manual that provides information for how to configure a GTX 23 in a G3X system. -

External suppression should be connected if a DME or TCAS is installed in the aircraft avionics system. The GTX 23 suppression I/O pulses may not be compatible with all models of DME or TCAS. Known incompatible DME 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 23 mutual suppression output. -

IDENT pulse for 18 seconds in Mode A replies. EXTERNAL STANDBY SELECT (remote STANDBY) is not a momentary input. When EXTERNAL STANDBY SELECT is grounded, the GTX 23 operates in standby mode. In this mode, the transponder will not squitter or reply to interrogations. -
Page 34: Serial Data Electrical Characteristics
For installations that enable ADS-B, RS-232 input #2 should be connected to a GNS 400W/500W-series WAAS enabled unit or a GTN 6XX/7XX series unit. This connection provides the GTX 23 with GPS data for ADS-B. The RS-232 output #2 is unused on the GTX 23. -
Page 35: Rs-232 Input/Output, Software Update Connections
4.4 RS-232 Input/Output, Software Update Connections GTX 23 software is updated using the RS-232 #1 interface. When wiring the RS-232 #1 interface to the rest of the system, it may be useful to splice in a pigtail connector that could be plugged into a laptop computer. -

Since the combined weight of the GTX 23 and its equipment mounting rack and connector is 4.3 lbs, the static loads which must be applied (Load Factor x 4.3 lbs.) will be as follows:... -
Page 37: Figure A-1. Upward Static Load Test
Examine all aircraft stringers, bulkheads and skin surfaces, which may have direct or indirect contact with the fabricated shelf. If it is determined that no damage or permanent deformation has occurred, the structure is of sufficient strength and the GTX 23 equipment rack may be permanently mounted on it. -
