Unit Type; Unit Id - Garmin GI 275 Installation Manual

5.3 Unit Type

The Unit Type page is used to configure the GI 275 unit as a specific type of display. This includes
Unit ID, System ID, Airframe Type, and Unit Configuration.
5.3.1

Unit ID

CAUTION
Failure to follow the procedure to set Unit ID before performing any other configuration
steps may result in configuration errors or configuration settings being overwritten by
another display. Unit IDs must be unique for each unit in the system.
A Unit ID must be assigned to each installed GI 275 prior to configuring the function of each unit.
• Unit ID – A unique ID number between 1 – 6 for each GI 275 installed in the system. Unit ID is
set to a blank default at the factory and must be manually set. For a single GI 275 installation, set
the ID to GI 1. The unit assigned GI 1 should also be set as the Master display (refer to Section
5.3.2). Each Unit ID must be unique and set using the following procedure:
When the GI 275 is powered on in Configuration mode for the first time (or after configuration settings are
cleared), it will automatically prompt the user to assign a Unit ID. This cannot be skipped.
Alternatively, the Unit ID can be configured by following the steps:
1. Verify all GI 275 units are powered off.
2. Power up a single GI 275 in Configuration mode, as described in Section 5.1.1.
3. From the home page, touch Unit Type → Unit ID → LRU and select a unique Unit ID between
1 and 6.
4. Touch Restart to apply the assignment.
5. Power down the display (do not power back on at this time).
6. Repeat steps 2 through 5 for the remaining installed GI 275s.
7. When all Unit ID assignments have been made, power up all displays in Configuration mode
before moving to the next configuration steps. The Unit ID assigned to each display is shown on
the left side of the display on the Configuration mode home page or on the Unit Type page.
CAUTION
For installations with more than one GI 275, all configuration settings made after the steps in
Section 5.3.1 must be done with all displays powered on and in Configuration mode.
CAUTION
Once all GI 275s have been configured, the Unit ID should not be changed. Doing so will
result in a loss of configuration settings.
