  • Page 27 The system combines primary flight instrumentation, aircraft systems instrumentation, and navigational information, all displayed on one, two, or three color screens. The G3X system is composed of several sub-units or Line Replaceable Units (LRUs). LRUs have a modular design and can be installed directly behind the instrument panel (or mounted to the panel in the case of the GDU 37X) or in a separate avionics bay if desired.
  • Page 28 2.1.1 System Architecture Figure 2-1 illustrates an example block diagram of a G3X installation. The flexibility of the system allows the installer to determine the architecture that best fits each installation. Only one GDU 37X display is required, but up to three may be used.

  • Page 29: Electrical Considerations

    This section presents information required for planning the electrical layout of the G3X installation. 2.2.1 Power Specifications All G3X LRUs are capable of operating at either 14 or 28 VDC (except the GAP 26, 010-01074-10). Table 2-1, Table 2-2, and Table 2-3 list supply voltage and current draw for the G3X LRUs, use this information when determining power supply requirements.
  • Page 30 GSU 73* 28 Vdc 0.80 Amp (max) *Garmin recommends using Mod 1 level GSU 73 in aircraft that use a +28 V supply voltage and intend to monitor current on high voltage devices such as the aircraft alternator. 2.3 Wiring/Cabling Considerations Section 15 lists the pin information for all LRU connectors.
  • Page 31 The installer shall supply and fabricate all of the cables. Required connectors, etc. are provided with the G3X w/GSU 73 Installation Kit (K10-00017-00). Electrical connections for the GMU 22 are made through a round 9-pin connector, and are made through D subminiature connectors for all other LRUs.

  • Page 32: Configuration Module

    2.3.1.2 Configuration Module The G3X system is designed to store configuration and calibration data in multiple locations to retain the configuration of the system during maintenance. Figure 2-2 shows the configuration module that installs on both the GDU 37X (PFD 1) and the GSU 73 connector backshell. In systems using a GSU 25, only the GDU 37X (PFD 1) will use a configuration module.
