10 GEA 24 (EIS INTERFACE) INSTALLATION
This section contains general information as well as installation information for the GEA 24. Use this
section to mount the GEA 24 unit.

10.1 Equipment Description

The GEA 24 is an input/output system used to monitor and power engine and airframe sensors for the
Experimental – Amateur Built (E-AB) and Light Sport Aircraft (LSA) markets. In a G3X Touch system,
two GEA 24 units may be installed to monitor and display engine data for twin-engine aircraft, or single-
engine aircraft with more than six cylinders. The second GEA 24 must be configured as EIS #2 as
described in Section 25.5.16.
• 9 pin network-power connector
• 50 pin miscellaneous connector for airframe sensors
• 25 pin thermocouple input connector
• 37 pin miscellaneous connector (for airframe sensors) will provide for the following input/output
functionality:
◦ Configure analog, digital, and discrete I/O capability
◦ Output digital measurement of analog input resistive sensors
◦ Output digital measurement of analog input voltages
◦ Output digital state of discrete input sources
◦ Output frequency measurement of digital input sources
◦ Control of discrete annunciator outputs
NOTE
If a GEA 24 is installed in a system that also includes a GSU 73, the GEA 24 must be
configured as EIS #2 as described in
