Telemetry connection question.....

Posted by David Kershaw on June 12, 2015 at 2:13pm

Hi Folks,

I am still very new to all of this but I never do things the easy way....

I already have 3DR radio fitted to my Pixhawk on the Hex I'm building but wanting more, I have a Minim OSD and a Teensy 3.1 telemetry adapter...

I have been told these 3 units can all be "daisy chained" together, ie, GND to GND +5V to +5V and TX to TX and so on....

Is this correct?

Any help with this would be great....

David.

    Can anyone explain the difference between TELEM1 and TELEM2?

    Or... Do I connect My Radio with the Mavlink Telemetry Adapter into "Telem 1"

    And plug my OSD on it's own into "Telem 2"???

      That looks like it would work.

      Good luck.....

    Correct - sort of.

    You can connect MinimOSD RX to your telemetry TX.

    Don't connect the OSD TX to the telemetry RX though or you'll get weird stuff happening.

    So, telem1 TX > Radio RX and OSD RX

    In Mission planner there is an option to enable telementry all the time. No harm in clicking that.

      Hello David.

                       Peter King on you tube has very good videos on connecting teensey,OSD,and your mavlink module.

      Good Luck.

      I did see this and in fact, that's where I got the board from but he only just skirts over the connection...
