I assume you mean BNC connector? Try this out http://www.readymaderc.com/store/ind...roducts_id=214

Question: Possible to change PWM frame timing?

Got a small? problem. Trying to use a Futaba SBE-1 [PWM to S-Bus encoder] with the RX700LR, but it does not work. From the logic analyser it seems that the problem [might] relate to the longer PWM 28ms frame of the RX700LR that is just outside the specs of the SBE-1 [3 to 27.3ms]. Pulse width limits are ok, but it looks like the longer frame duration might be messing proper detection in the SBE-1. The SBE-1 works perfectly with a RX that outputs a PWM 14ms frame. Is there any way to adjust the timing of the PWM frame of the RX700LR?
Any other ideas/suggestions appreciated.
Cheers

28mS is very normal for 12ch ppm,
suggest the s bus converter to fix their problem,
or use less channels, so it works.

hi, i have a problem with one of my long range receivers. i did build a plane with a mfd ap in it (connected via ppm). when i made my bench tests i recognized channel 6 wasnt working, the ap didnt react on any channel 6 input. channel 1-5 was fine.
as i had two other unused long range receiver i tested them and they both work without any problem, 1-6 over ppm all fine. switched back to the first one, and again channel 1-5 work, channel 6 nothing.

the one with the problem is a normal v7 long range.

the two working ones are a v6 boostet lr and a normal v7 lr receiver.

hi thomas,

i dont know if the chan6 is missing in the ppm, at least the autopilot doesnt react on it. with other receivers i have no problems, just with one of mine.

yes i did a rebind.

Very cool Thomas thanks

Homer is going to visit me and we plan on a road trip to fly fpv soon, extra UHF rx will be nice

THAT you need to find out..
it is easy to check if a servo react normal when plugged into ch6 connector,
if this is ok, your autopilot is bugging you.

SUPER david, give my best regards to Homer

could be trigger levels or timing or forgot binding,
if the wanted signal is on ch6 connector it will also be in the ppm signal,
a free audio channel scope software is very usefull for debugging such matters,
unless you got a nice digital storage scope ?

Rebinding the TX with the RX with less channels [8ch] still produces a 28ms PWM frame [which actually makes sense, why should it have a variable frame timing], unless of course I am doing something wrong.

Wasn't S-Bus support planned for the RX700LR? Is there a beta firmware that could try?
