GEM Configuration Pages
G1 GEM's are NOT field-configurable so it is essential to supply all the essential aircraft engine data to
Insight at the time of placing the GEM sales order. Failure to provide the correct configuration data will require
the G1 GEM to be returned to the factory.
G2, G3 and G4 GEM models may be configured in the field but if all the necessary data is supplied to Insight at
the time of placing the sales order, the GEM can be pre-configured at the factory. Installation will go quicker and
easier if Insight does the configuration for you.
GEM models G2, G3 and G4 are configured by special pages not accessible in normal operation. Once saved,
configuration data is stored in secure non-volatile memory until overwritten by new configuration data.
To access the configuration pages turn off the GEM for five seconds, and then apply electrical power while
holding in the Page (PG) knob. The GEM will allow access to the Registration, General Info, Engine, Date/Time,
K-factor, and Misc Configuration pages.
Information entered on the Registration page will appear in the header section of each datalog file.
The General Info page displays technical diagnostic data.
Engine configuration data must be set to match fuel system and engine specifications and limits.
Date/Time allows setting of the GEM's clock and calendar for datalogging.
K-Factor allows adjustment for non-standard Fuel Flow Sensor pulse rates.
Misc allows for setting of RS-232 data transmit protocol.
Turn the PG knob to switch between pages, use the Select (SEL) knob to scroll and modify configuration items
within each page. Under "Save Config" select "YES" push the SEL knob to save changes on each page. After
configuration changes have been saved, turn off electrical power for five seconds and then restart the GEM to
resume normal operation. Do not perform configuration changes in flight.
Refer to the G-Series Pilot's Guide available from Insight for more information regarding configuration.
GEM Software Updates
Contact Insight Instrument Corp. for information regarding software updates.
FLIGHT TESTING THE GEM
It is essential that the GEM be flight tested.
On power-up the GEM will briefly display a status page showing Part Number, Serial Number, etc. Check to
ensure that the REDLINE numbers displayed on the status page match the Aircraft Engines CHT/EGT/TIT
limits as specified in the aircraft Type Certificate or Flight Manual.
The GEM must be observed in all phases of flight for consistency in performance. If a problem is noted during
the flight test, discontinue the flight test and trouble-shoot the system. The GEM's datalog system
automatically logs every flight.
Should you have any questions or problems during installation or trouble-shooting of the GEM don’t hesitate
to contact Insight Product Support.
