Introduction OTHER REQUIRED MATERIALS The GX50/60/65 is intended for use with standard aviation accessories. External devices required for various installations are listed in the System Configurations section on page 4.
Installation SECTION 2 - INSTALLATION This section describes the installation of the GX50 and GX60/65 including mounting, wiring, and connections. A post installation check-out procedure is included at the end of this section. PRE-INSTALLATION INFORMATION Always follow good avionics installation practices per FAA Advisory Circulars (AC) 43.13-1A, 43.13-2A, AC 20-138, and AC 20-67B, or later FAA approved revisions of these documents.
Installation EQUIPMENT MOUNTING Once the cable assemblies have been made, attach the 15 and 37 pin d-sub and coaxial cable connectors to the rear connector mounting plate and the mounting frame as illustrated in Figure 4 and Figure 5. Route the wiring bundle as appropriate. The rear connector plate should be attached to the mounting frame before installing the frame in the instrument panel. The rear connector plate can be used to tie down the cable assemblies.
Installation Figure 4 Mounting Frame Assembly Figure 5 Cable Routing Apollo GX50/60/65 Installation Manual 11
Installation ELECTRICAL CONNECTIONS Wiring necessary for installation of the GX50/60/65 includes the rear panel electrical connections and the antenna cable placement. The 15 and 37 pin d-sub connectors and coax connector(s) may be wired before or after being installed in the mounting frame. The recommended connecting wire size for the connectors is 20 to 24 AWG. Wiring diagrams are included on pages 16 through 22.
Installation SPEAKER AND HEADPHONE OUTPUTS (GX60/65 ONLY) Connect the speaker and headphones to the output pins on the rear connector. MICROPHONE INPUTS (GX60/65 ONLY) Microphone input connections should be made using a twisted pair shielded cable. Attach the signal ground to the mic ground pin on the rear connector and connect the shield to the rear connector plate. TRANSMIT KEY INPUT (GX60/65 ONLY) The TxKey input on the rear connector must be pulled low to ground to enable the transmitter.
Installation GPS ANTENNA The mounting location and cable connections for the GPS antenna are very important. The antenna should be mounted no closer than two feet from VHF comm transmitter antennas, six inches from other antennas emitting less than 25 watts, and two feet from higher power antennas. Special care should be taken to ensure that the GPS antenna is not mounted in close proximity to antennas that may emit harmonic interference at the L1 frequency of 1575.42 MHz.

Used to check internal circuits and display voltages. “EEPROM BYTE 0000:” ...............Factory use only. Used to display eeprom setup memory. GPS NAVIGATION CHECKOUT Switch on the GX50/60/65 in the normal mode to complete this part of the checkout. The GX50/60/65 will go through a sequence of self tests.
Installation d) Repeat for additional frequencies as follows. 121.125 MHz 131.225 MHz 121.175 MHz 131.250 MHz 121.200 MHz 131.275 MHz 121.225 MHz 131.300 MHz 121.250 MHz 131.325 MHz 131.200 MHz 131.350 MHz e) Repeat for each comm transmitter. f) If the GX50/60/65 is susceptible to VHF comm transmitter interference, then better isolation, or distance, may be required between the GPS and VHF antennas.
Installation appropriate altitude and over all normal flight attitudes. Performance should be checked using low, high, and mid band frequencies. FINAL SYSTEM CHECK The GX50/60/65 GPS navigation functions should be complete at this time. The final check includes checking database, entering a direct to waypoint, and checking the navigation functions. Start with the unit turned on and operating in the normal mode. Refer to the user’s manual for operating instructions. 1. Verify a valid position is displayed.
