3dr telem and minimosd not working at the same time

Having problem to make work both at the same time, Both work well alone…

I do have a Y connector going out of the APM with GND/+5/Tx/Rx going to minimosd and telemetry 3dr,

When each add-on plug seperately work fine, but together not working ether i lose 3dr telem or screen display on minimosd,

When 3dr telem work with GND/+5/TX/RX and adding minimosd with same Y (without tx on minimosd) going to APM = 3dr telemetry goes down no communication and minimosd work fine.

When Minimosd work with GND/+5/RX and TX and adding 3dr telemetry with same Y (including TX) going to APM = I lose minimosd screen display and unable to connect with PC to 3dr telem.

If someone know’s what i’m doing wrong?

APM 2.5.2
Minimosd extra 2.2

Hi Apollo69,

For the moment we’ll just accept that you have the GND and +5v connected to both the Telemetry Radio (now to be referred to as TR) and to the MinimOSD (now to be referred to as OSD). The correct connection should be:

APM TX > TR-RX + OSD-RX
APM RX > TR-TX Only

Are you making the correct connections RX-TX and TX-RX as shown above, not TX-TX and RX-RX?

Hi Nathaniel,

Yes,
APM TX > TR-RX + OSD-RX
APM RX > TR-TX Only

When both are plug in, as per above refer, my first post explain what happen.

But i try both seperately and and they work fine…just to make sure TL and OSD work.

If i’ve plug Apm-Tx to Tl-Tx it wouldn’t work

Same for osd when plug seperately.

So i assume i did not make a mistake on that…

Thanks
