I wonder if anyone active on this forum has any experience decoding the serial data from the EIS4000? There are lots of software gurus here, so I thought I would ask.
Obviously the people at GRT know it, AFS has done it to allow the engine data to be displayed on the EFIS. There have been other forum discussions and there are some things online but they are all several years old and I have a couple documets from GRT regarding. Any programs out there seem to use DOS or a hyperterminal on a computer that has a actual serial port (not USB).
I have a non-standard engine and my wants differ from how all efis systems display the data.
My problem starts pretty much at step 1.... There is supposed to be a header in the serial data (FE FF FE)... but I do not get this. I do get a repeating string of data but not the header. Is there some manipulation of the data that needs to be done before it's in the right format? or is this a USB comm port problem?
What I should get:
What I am getting (I used the 00 00 00 as an easy way to pull out 1 data set) there is no FE FF FE, and too many FE's.
(hopefully these links work)
