3.7 Final Installation
For final installation and assembly, refer to the outline and installation drawings shown in Appendix D of
this manual.
a. Assemble the connector backshell as described in Appendix B.
b. Attach the connector to the rear plate using the screws provided in the connector kit.
c. Mount the unit rack to a mounting location that considers the mounting requirements in Section 2.6.
d. Assemble the rear plate into the GTX 23 unit rack using screws provided with the rear plate.
e. Insert the GTX 23 into the rack, noting proper orientation as shown on the installation drawing in
Appendix D.
Do not use excessive force when inserting the GTX 23 into the rack. This may
cause damage to occur to the connectors, unit, and/or unit rack. If heavy
resistance is felt during installation, stop! Remove the GTX 23 and identify the
source of resistance.
f. Lock the GTX 23 in place using the lever-locking handle. Fasten the handle to the GTX 23 body using
the provided Phillips screw.
Start the handle screw into the hole carefully, to avoid cross-threading. Do not
apply torque in excess of 14 in-lbs to the handle screw. The application of torque
exceeding 14 in-lbs to the screw will damage the LRU case and/or retaining
hardware.
3.8 Post Installation Configuration and Checkout
The GTX 23 Mode S Transponder will not provide valid outputs until the aircraft
post installation configuration procedures are completed.
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.
3.8.2 Interference Check
Turn on and verify operation of all avionics equipment except GTX 23. Then power the GTX 23 on, and
verify there is no interference with any other equipment in the aircraft. The operation/performance checks
should be made with all other avionics turned on. Verify that there is no interference during any mode of
transponder operation.
