4.5 Configuration Module Installation
NOTE
Installations with an optional GAE module do not require a configuration module.
NOTE
The configuration module stores unit configuration data. This lets the installer remove and
replace the GTX without loss of configuration data. Installation of the module is part of
the aircraft harness.
GTX 335 and GTX 345 standard kits include a configuration module. Garmin recommends to use the
configuration module with these models, but it is not required.
Do not install the configuration module in the connector backshell when the GAE is installed on the
connector backplate. The GAE module has a built-in configuration data storage device and interfaces to
the GTX 3X5 through the same pins as the configuration module.
The GAE wire harness is routed out the back of the backshell and plugged into the GAE when the
backplate is assembled. Refer to section 5.12 and figure B-11.
Refer to figure 4-4 and figure D-1 for this procedure.
1. Remove 0.17 inches of insulation from the end of each wire (2) before crimping.
2. Crimp socket contacts (3) onto each wire of the four-conductor wire harness (2).
3. Insert crimped socket contacts (3) and wires (2) into the applicable connector housing location.
Refer to figure D-1.
4. Plug the four-conductor wire harness (2) into the connector on the configuration module (1).
5. Insert configuration module (1) into the backshell recess.
6. Point the connector housing so the inserted four conductor wire harness (2) is on the same side of
the backshell as the configuration module (1).
