Data Link; Stormscope; Audio Panel; Transponder Control - Garmin GI 275 Installation Manual

3.3.5

Data Link

The GI 275 can interface to a GDL 69/69A SXM to receive SiriusXM weather service with a valid
subscription. It does not provide control for music.
3.3.6 WX-500 Stormscope®
The GI 275 can receive data from the WX-500 Stormscope® system to provide the display of lightning
data. The GI 275 cannot be used to control the Stormscope® system. A controlling display (e.g., GDU 620,
GDU 700/1060, or GTN 6XX/7XX) must be present in the system to display Stormscope data on the
GI 275.
3.3.7

Audio Panel

The GI 275 can be interfaced to an audio panel for audio alerting. An interfaced audio panel cannot be
controlled via the GI 275.
3.3.8

Transponder Control

The GI 275 can interface to GTX 345 series transponders to provide a Transponder Control page when
configured as an MFD or Standby ADI/MFD. This allows the GI 275 to control transponder code, the
IDENT function, and the mode of operation for up to two interfaced GTX 345 transponders.
3.3.9

Autopilot

Various autopilot systems can be interfaced to the GI 275. Compatibility of the autopilot system with the
GI 275 system must be verified before installation. This STC does not include data for autopilot system
installation. The autopilot must be installed per aircraft (or autopilot system) manufacturer data.
The GI 275 can provide AC or DC heading and course datum (error) outputs based on the HSI heading bug
and course pointer setting. When enabled, the GI 275 can drive the heading datum output based on GPS
steering (GPSS) from the selected navigator, acting as a roll steering converter. The GI 275 will provide
analog deviation, associated flags, and ARINC 429 GPSS information based on the navigation source
currently selected on the HSI.
Except when interfaced to Garmin autopilots, the GI 275 does not provide altitude preselect functionality.
Any existing altitude preselector must be retained and any altitude source being provided to the preselector
must also be retained.
