We have been working to get our Uvionix Echo up and running in our RV-10. We tried the wireless options but were not satisfied with the performance, we were unable to get a passing grade. We installed the GNS MUX Cable from Uavionix. The MUX gets GPS data from the 430W, encoded altitude from the GRT HX (set to 9600 Fuel Air Data Z), transponder squawk from the GTX 327 (set to remote out). The ADS-B data is broadcast back to the GRT HX.
The problem is that we can not get pressure altitude or transponder squawk. We have tried piles of configuration settings per other success stories on here.
The last thing to try (I think) is to upgrade the firmware on the GTX 327 from 2.09 to 2.13, however others on the forum have had success with the GTX 327 working on previous versions of firmware. Can anyone confirm the upgrade is necessary? Any other ideas to try? Garmin says an update is not required, Uavionix says it has to be....
Thanks in advance - Jason
Solved: I got a call back from Uavionix and they told me that they had a run of MUX cables that were programmed incorrectly. I had to change COM1 to 38400 Baud and keep the other settings per their instructions. I am now seeing altitude from the GRT and squawk from the GTX 327. HOWEVER, meanwhile I had the firmware of the GTX 327 upgraded to 2.13, so it is not clear to me if the update to the GTX firmware was actually required. Thanks for all the advice. - Jason
