Hi everybody,

I was looking through the logs collected by the Jeti DS24 from the Spirit Pro, which in turn collects the data from a Jive Pro and saw that the BEC Voltage measured by the Jeti receiver is different from the BEC Voltage measured by the Jive. The one from the Jeti is correct.

My config is as follows:
Jive Pro 80+
Spirit Pro collectic telemetry from the ESC throught the Spirit Kontronik 4 pin servo cable (not the new SAT one)
REX6 Jeti receiver on EXbus
Jeti DS24 logging the telemetry from the Spirit

This is another log capture with RPM visibile, heli on the ground with blades installed.

So both logs show the same behaviour.

I have installed the latest version for all the electronics:

Spirit Pro 3.2.2
Jive Pro 1.14
REX6 1.14
DS24 5.05

Any insight will be appreciated.

Thanks

After looking at the graphs, it seems that the S Bec Volt chart, is in fact a wrongly mapped temperature reading. I've looked through several logs and the SBec Volt line is behaving like a temperature increase chart (of course, the value is incorrect).

Another example:

Hello,

we highly recommend using Telem Kontronik V2 cable, since the old protocol is rather unsupported by Kontronik as they added new open TelMe protocol.
There were more shortcomings of the old protocol, for this reason Kontronik released this new one. It is supported for few years now and has many benefits.

Hi Tomas,

I already ordered the new cable. After I install it, I will come back with my findings.

Thanks,
Vlad
