GRT Avionics

Good Day Jeff, I wired the outputs (per the diagrams) and as it relates to wiring to the HXr or the EIS AUX Inputs I chose to wire it from the L2e Dongle directly to the EIS (Pins 16 and 17) and not to the EFIS. I see the instructions below were for the HXr instead of the EIS, however thought I was ...

Thanks Jeff,

Andrew at AeroSafety Systems asked what voltage is the Warning light pin floating up to when NOT grounded?

Thanks,

Good Day Jeff, This is a follow-up to our work with beta testing the AeroSafety Systems Annunciator (AH502) with the GRT HXr's (using the Garmin G3X Protocols). Question: The AH502 has direct connections with the G3X via these Interconnects: 1. RS232 TX - to AH502 Digital Input 0 (Pin 22) 2. RS232 G...

Good Afternoon Jeff, Jon and GRT team… I spoke to Jon last week on this and he asked me to send this email to be sure on best answer. Reminder: My equipment related to this question is: Two (2) Lightspeed Engineering Plasma III Electronic Ignitions Two (2) GRT HXr EFIS One (1) GRT EX EFIS One (1) GR...

Thanks Jeff, I just learned from ARTEX that they program all of them with the "Aviation" format (not the NMEA0183) and will need the 9600 Baud Rate. If I want to use the NMEA0183 it would require me sending it in to a 3rd party (like Dallas Avionics, etc) for "reprogramming" whic...

Good Afternoon, I understand the HXr EFIS series will provide capabilities to show fuel levels (in set bar graphs) with capacitive type float fuel senders. Could you simply look at the outputs of this unit and let me know if it would be compatible (I want to use this for the SUMP tank only in my Vel...

As you are most likely aware, Lightspeed Engineering provides an output to display Timing Advance information. This info is provided with mV so an op-amp is required to bring the signals to the 0-5V range and be able to be displayed on the HXr EFIS. Lightspeed provides two ways to do this, one with ...

Thanks Jeff and Happy New Year, So if I understand correctly; 1. If I have the output you mention below available on either HXr I can use that...or 2. I can use the Safely Outputs (would those be the extra SPC ports?) 3. I am installing your GRT Autopilot servos so does that automatically take one o...

Good Morning and Merry Christmas Eve to All, As part of my panel/aircraft upgrades, I am also installing an ELT (ARTEX ELT-345) and would like to understand what capabilities the HXr has for displaying info and functionality with this. In the ARTEX manual it states baud rates based on different setu...

Good Morning Jeff and All, I am in the middle of my install (2HXr’s and a Sport EX). I have the CO Guardian 353P Remote unit and even though have triple checked my pin outs (for both correct locations and continuity) I am unable to get any data in the counter. Here are my settings (the manual states...
