Hello
I would like to connect a Spektum SPM4649T receiver and 2 additional sat on a Spirit Pro.
Sat connectors are already used, primary for esc telem, and secondary for geolink device.
Spektrum SPM4649T must be connected to ELE/PIT/AIL and RUD connectors, and the 2 additional sat connected via Spektrum multi adapter cable to the same connectors !
So, is it possible ?
Do I have to duplicate ELE/PIT/AIL and RUD connectors with Y cable ?
I know that I could connect 1 sat directly to the SPM4649T rx, but I would appreciate the 2 sat redundancy on my big heli.
Many thanks for advice.

Hello,

unfortunately this is not possible.
You can connect just one satellite with SPM4649T in this case.

It is still possible to use Spektrum Multi Adapter, but just for one satellite. So normal Spektrum Adapter V2 will do the same job.

You could actually power it from for example AUX2 port (if unused) and connect the single wire pin at the RUD port (signal position) which is used for JETI cable too. So you have to combine these two cables to get just one for the RUD port. With a needle you can do that easily.
Alternatively Y-cable can do the job as well but will make it heavier.

Hello Tomas

I finaly would like to use only 2 sat without the Spektum SPM4649T receiver, on a Spirit Pro, in order to improve reliability, and for wiring simplification.
Sat connectors will be already used, primary for esc telem, and secondary for geolink device.
So, with the two sat connectors used on the Spirit Pro, can I use the Spektrum Multi adapter in order to connect the 2 sat on the RUD and ELE/PIT/AIL connectors ?
Is the Spektrum Multi adapter have a step down for 3.3v sat power supply ?
I understood that I have to bind the sat on the Spirit Pro sat connector, before connecting it on the Multi adapter cable.
