23.5.16 System ID
Pins 1 and 2 must be left open (floating) for a single GEA 24 installation. When using a GEA 24 and GSU
73 in the same system, pins 1 and 2 should be connected together in order to configure the GEA 24 as the
EIS #2 LRU. If two GEA 24s are installed, connect pins 1 and 2 on the second GEA 24 together in order to
configure it as the EIS #2 LRU.
When using two GEA 24 units to monitor a single engine with more than 6 cylinders, connect cylinders
1-6 to the CHT/EGT 1-6 inputs on GEA 24 #1, and cylinders 7-12 to the CHT/EGT 1-6 inputs on
GEA 24 #2.
When using two GEA 24 units to monitor twin engines (or a larger than normal single engine), connect
pins 1 and 2 on the second GEA 24 to configure it as the EIS #2 LRU.
