ahhh yes!! this is a very good idea!! The The TTL i got of Van is set up with the servo plug..perfect!

cheers

I changed the OSD mode to 3 and the RHS column of data shows that the DOSD sees 8 channels and lists their outputs.

In the 9X menus both 'mixers' and 'limits' list 16 channels so I assumed that this is the number of receiver channels supported.

I have been through a couple of versions of the Er9x manual and can find nothing about changing the number of output channels. Isn't this fixed by the firmware?

But I'm pretty sure it goes in the same spot as the Dragon Commander and if so I have it connected correctly and don't know why I'm getting a connection failed error.
The cable was only used a few times when new so I know it should be working.
This did work before? (TTL) If yes then nothing was changed? Example TTL TX to OSD TX, TTL RX to OSD RX and Ground. No power from TTL to OSD conected right? Also the comm port was selected correctly on the PC end and drivers installed? Just trying to cover as much grounds here.

I haven't found if I can use a 4s as the main battery & still not use an external battery to power my vtx? Can this be done, does the DOSD have a regulator to drop the voltage down to 12v ?

Thanks Marc.

Still having issues with my Dragon Commander

For some reason I can't get the USB cable working. The program keeps saying connection failed. And it's connected correctly too.

I pretty much always use the Dragon Commander to change features and it works perfect.

I recently got a Dragon Link and now I need to adjust the RSSI.
It gets 100% when the TX is on and 0% when turned off but how do I know what to adjust the numbers to.

For instance in the high RSSI setting I can set anywhere from 1.02 all the to 3.3 which is the max setting and it says 100%.
If I set it to 1.0 I get 0%.

I don't know if I should leave it at 3.3 or 1.01. I want the RSSI percentage to immediately start going down at the first sign of less signal.

4S is really pushing it to power the DOSD. Yes, there is a voltage regulator on the board. Yes it will get hot when having to step down the voltage from a 4S battery. So, from what I recall, a 4S is the absolute maximum to power the DOSD, but not really recommended.

edit: From page 75 of the DOSD Manual:
The DOSD+ has an on-board switching power supply that is very efficient and heavily filtered so as to prevent the possibility of supply noise getting in or out of the lines. Being a switching power supply means that the regulator will stay cool all the time, without wasting power in heat dissipation, thus extending your battery life. It also allows for a wide range of power supply voltage to be used - from about 4.6V up to 20V (although we do not recommend using more than about 16V).

I'd add in that it is not recommended to use a <5v source to power the DOSD either. This if very close to the minimum voltage to operate and a voltage dip could result in a in-flight reset...not good to do while in flight.

Thanks, I knew you would be the one with the answer. I'm only using my DOSD for the OSD not for A/P. it's for a quad.

hmmm... I want an AHI... Ill have to work on that... need a way to pull data from some of the multirotor stuff... Id love to see my CopterController's IMU put to use for AHI...

Hello guys,

I've been reading the manual of the DOSD and I have some questions:

1.- As I understand, if I power the DOSD through the current sensor or by the power pins,either of the two ways I won't get power for the servos, right?, If so, I read that I could power them from the ppm line that will come from the Dragonlink to the DOSD or to power them from one of the PWM's right?

2.- I'm waiting for the USB-TTL coverter for programming the board, do you recommend me to wait for the cable for the first run, or can I start up without the coverter?. I'm eager to start

Thanks,

Juan
