GPS Interface Connections

GPI Interface Connections:
All
EDM 700, 800, 900, 930 and FS 450 (Single and Twin) will receive flight data from your GPS
(this is a standard feature on the FS 450’s and a standard feature which is included with the Fuel Flow option).
Fuel Required to Waypoint/ Destination(REQ):
This parameter will be displayed only if your EDM 700, 800, 900, 930 and FS 450 (Single and Twin) will receive flight data from your GPS (this is a standard feature on the FS 450’s and a standard feature which is included with the Fuel Flow option). This will tell you how much fuel is required to get to the next waypoint or destination programmed on your GPS, based on your current fuel flow rate and present position.
Fuel Reserve (RES):
Fuel reserve when you arrive at your next waypoint. This parameter will be displayed only if your EDM 700, 800, 900, 930 and FS 450 (Single and Twin) will receive flight data from your GPS (this is a standard feature on the FS 450’s and a standard feature which is included with the Fuel Flow option). This will tell you how much fuel reserve you can expect when you arrive at your next waypoint or destination programmed on your GPS, at the current fuel flow rate.
Distance per fuel units. Both the REQ and the RES indicator lights on the FS 450 will be on at the same time. It will tell you your miles per fuel unit such as miles per gallon, miles per liter or miles per pound. It is based on your current ground speed and current fuel flow rate.

Diagnostic Messages, Fuel Flow
The following displys indicate a malfunction in the Fuel Flow Option transducer or associated electrical connections:
0.0.GPH Zero’s indicate Fuel flow is too low to register
– – – Dashes indicate No fuel flow transducer signals
GPH
– – – Dashes indicate No fuel flow transducer signals
