Jlog wiring for Graupner HV160 to Jeti EX

[enterprise7]

I am trying to wire a HV160 T+ to a jlog 2.6 to a Jeti R9. I have starred at the different wiring diagrams. I get that I have to route the telemetry wire to Kosmic bus, but it shows it being split to two pins. Is this a either/or, or does the signal need to be split and feed both pins. I assume the other far left and right pins are power and ground on that bus.

Then I use the COM port to sent signal and ground back to the R9 with no power?

It is necessary to put the two yellow pins in parallel - running to the telemetry 1-wire of the ESC.

Power supply: either also via the KOSMIK port of JLog (especially if the SJ ESC has a BEC) or via JLog's JIVE port, see the diagram: the "yellow" pin is plus (atypical pin assignment).
Use the latter port, "JIVE port".

[enterprise7]

Yes, my ESC has a BEC so I will wire it all into the Kosmik port and Y the two pins together.

Thanks for the information.

Got some time on this setup now. The jlog only sends data to the RX when the ESC updates the Mah used so the data stream is not continous. Is this a ESC setting or something I can fix in the jlog?

I have another one now with a castle ICE2 HV and it works perfectly.

No special setup regarding JLog or the ESC.
You should get updates on
- Ubat
- Imot
- rpm
- tFET
and mAh cumulated by JLog.

Means: if you have movement in mAh then you should at least also have it in Imot because JLog relies on the Imot updates.

The ESC is a HoTT sensor of type "ESC" - and JLog emulates a HoTT receiver to can read the HV160 in pseudo-graphical (binary) mode.

[enterprise7]

So only getting periodic updates is normal? I do get data on the all the other readings, just not continous so I will only get a RPM reading when the Mah used updates which is not very usable.

[dl7uae]

That's new to me. The ESC as HoTT sensor is asked for data every 200ms.

It worked the first day I had it setup on the bench. I watched it yesterday and the green light only blinked when it would send 10mah used update. I rebooted, removed the SD card, and it did the same sort of thing. It happens so regularly that I ruled out the wiring as I checked that. I also plugged it direct into the EXT port as I currently have it in a expanded.

Essentially I wanted to know where to go trouble shooting. Is there anything in the setup that affects this. Maybe I did not set something up correctly. Should I try to reflash it?

I don't have any access to the ESC programming as I had to borrow a Graupner radio to set it up.

Luckily I have a Main switch 200 and I don't have to have this telemetry to get everything to work.

Is it possible that the system does not like having the Main Switch and the jlog working at the same time?

[dl7uae]

The switch and JLog in parallel on the same EXT port without an expander?

[enterprise7]

No, they are on a expander. I tried the jlog just plugged into the EXT and got the same results.

[dl7uae]

That is strange... because it had worked before already..

Although I do not think that it could be the config: please attach your CONFIG.txt here, also version.txt.

If you look at the green LED: is this a fast continuous flashing? "Fast" means about every 400ms one time on/off.

I discovered what the issue was today. I use Hitec brushless servos in this plane and I had a PAD installed for the regenerative power the servos put back into the servo bus. I again got great data stream on the bench and went to the field and hooked everything up and had the same issue. Disconnected the PAD and all was good.

[dl7uae]

"PAD".. What a BS!

Use a R2buffer (supercaps) or Opto BEC Guard but not a Schottky diode somewhere in the wire salad. This produces more problems than it could avoid.
