5.4 Interfaces

This section specifies the configuration and setup of the GI 275 in order to interface to all required and
optional equipment allowed by this AML STC. Each display must be individually configured to match all
applicable interconnects (refer to Appendix B) that define each display as either an ADI, HSI, MFD, EIS,
or standby indicator.
The Interfaces page allows the GI 275 display to be configured to interface to LRUs installed as part of the
GI 275 system as well as previously installed equipment that is approved to interface to the GI 275 under
this STC. Refer to Appendix C for equipment compatibility.
The configuration for a particular display will vary based on the following:
• GI 275 unit variant (i.e., Base, ADAHRS, or ADAHRS+AP)
• Instrument Type (e.g., Primary ADI, EIS, etc.)
• Number and type of other GI 275s in the system
Each installed display must be individually configured based on the interfaced equipment.
Depending on the interface that is selected, further actions may be required by selecting the setting, as
shown in Figure 5-4, and configuring them appropriately. Some selections may be grayed out until a
preceding selection has been configured.
The configuration tables in this section show available interface options as well as available ports. The port
assignments must be made to match the aircraft wiring.
NOTE
The port availability at each LRU configuration will vary depending on previous
configuration actions. If a port was previously configured for another LRU, then that port
will be grayed out and not available for selection.
