4.3.3
GPS Data Output Interface with Remote Switch Harness
Referring to the wiring diagrams in Subsection 4.3.2, install a GPS data output
conductor as follows:
1.
Run a minimum 24-AWG conductor from the GPS data output to the remote switch
harness DB15 plug.
2.
Connect the GPS end of the data conductor in accordance with the GPS
manufacturer’s recommendations.
3.
Disconnect the harness DB15 plug from the ELT.
4.
Perform the following steps if the back shell of the DB15 plug has not been filled
with RTV or other potting compound. If the plug back shell is potted, proceed to
Step 5.
a)
Strip the insulation from the conductor back approximately 1/8” (0.125”).
b)
Solder the conductor into the Pin 9 solder cup of the plug in accordance with
the wiring diagrams shown in Subsection 4.3.2.
