EIS serial out not working?
Posted: Mon Jul 22, 2013 2:43 am
I just powered on my system for the first time...very happy, but the EIS is not communicating with the HXr. The EIS is getting data because I can see volts, amps, oil pressure, oil temp, cht, egt on the EIS(which is blind mounted in my Long EZ). Connecting to EFIS is the easiest part of the connections(green/black wire on EIS to green/black wire on EFIS)..GPS, TRXPR was much harder and they all work!
So any hints? I checked continuity and location of the pin on the EIS all the way to the front...I'm pretty sure the other end of the wire going into the EFIS was pre-punched by GRT. I still need to verify pin location on the EFIS bundle....
EIS software version is 83, EFIS just back from the shop so assuming it has the latest software...soon to be trying the beta with Bluetooth.
