Along the same lines, I just got a new D8R-II plus from Aloft, and an Ebay RSSI-DAC converter (ordered). With the older D8R's it was said they needed new firmware to get RSSI out of the DAC converter; do the new D8R-II plus need it, and if so, what cable/interface is necessary.

@RENATOA & Kilrah, thanks! I wasn't aware of that.
I knew about the D8[x] and noticed some weeks ago in D4FR while checking it's pulse generation.



Ended up not testing the D4R-II.
I suppose in the case of the D4FR there is no way to update it.

Seems I'll have a fw flash party tonight.

Yes, you need to flash the D8R-XP's firmware. Note you can only have RSSI together with PPM output mode.
To upgrade, you just need the USB cable. http://www.hobbyking.com/hobbyking/s...USB_Cable.html

My RX is the D8r-II plus. I thought with the DAC converter I can have all of the channels plus RSSI. Am I mistaken about this. Do I need to reflash this one too? Does Aloft sell the correct USB cable?

If you bought eBay RSSI decoder you don't need reflashing, it works as is on any D8R receiver except the first V1, having +5V in the middle of serrial line.

Thanks! Good to know. The Ebay decoder is on its way from Hungary and of course I got the RX from Aloft in a couple of days. They are great!

Put my order in today for the Frsky. Am I reading this correctly, The Ebay decoder will give me RSSI without setting the Rx to CPPM?

got a email from the guy in hungary, saying I still need to flash the Rx..
in his mail he pointed me to a few webpages,
firmware: http://file.emiter.hu/Modellezes/FrS...pdate_CPPM.rar
and method: http://code.google.com/p/uavp-mods/w...SkyProgramming

now here's where it gets a bit 'fuzzy'...
the method page shows a PC hardware part, that is now discontinued
the firmware -appears to be- the same as the firmware available from FrSky's website. (maybe..it seems to have the same release number.)

from what I could gather, the 'update' puts cppm on ch8's output, while leaving ch1-7 as before..
and.. something about needing the update to get rssi onto the side pins of the Rx.

I -really- dont want to lose ch8. I'm already using 7ch into the Naza, and was hoping for ch8 to be able to pan the FPV camera.

The FrSky USB programmer from hobbyking seems to have a plug that would fit the transmitter module, but not the receiver...

hmm...

several people make OSD units. Several make receivers. Why cany they get together and make some form of 'standard' for RSSI, and BUILD IT INTO the receivers... or is that asking too much??

He must be drunk...

This is the ebay device:
http://www.ebay.co.uk/itm/FrSky-RSSI...-/120724292816

and it outputs on blue wire analog RSSI from any D8R receiver newer than V2, no reflashing needed !

Here a video showing the process:

Hello!

Origin FW not send telemetry datas via side port! Therefore need update for CPPM (and telemetry send) FW version.
The result is:
7ch normal PPM
+1ch CPPM
+telemetry datas via side port (for RSSI-DAC converter)!

BR!

+1

I feel real happy that there is an inexpensive way to
get RSSI. My DAC is ordered and on the way. I already have the DR8-ii plus waiting.
