Looking at the Sport 10.1 Install manual for wiring up several analog inputs. Not much info on the how but a lot of info on the marketing!
For the older GRT EFIS interface they used 12vdc voltage source and a series 1K resister to one of the end terminals on a trim pot, the other end was ground and the third terminal or wiper was the input to the analog point on the EFIS.
On their EIS 4000 units they had a 4.3 regulated voltage that was applied thru a 10K resister much like the above and again the wiper was terminated to the EIS as an analog input.
The Hr and HXr GRTs series shows tieing the wiper and one end of the pot together and running that to the analog input, And ground the other end of the pot. Guessing the EFIS is suppling voltage to the external devise and that is done in the Menu set up along with what they are calling PULL UP RESiSTORS.
My question is :
Looking that this Sport 10.1 they really don't have a 4.5vdc regulated voltage to do it the old way nor do they show a typical method in the manual for how to do that analog input. Is it all done thru the Set UP? if so which connection is made to that analog input point ?
Without a 4.5 regulated voltage source on the pin out for that 10.1 Do I assume it is supplied from the EFIS and wire like the Hx or HXr series? Expecting the Menu and set up to fill in the blanks? A simple diagram in the install manual would make it really easy .
