You won't be able to use two satellites plus the 4649t when running every single possible accessory. You will be able to run one satellite and the 4649t which will work just fine, this is just like running a dual sat setup since the 4649t is a receiver as well.
CH0 is fine for the optiguard.
You should be able to get all connectivity you need with the spektrum mutli cable.
https://store.spirit-system.com/en/acce ... multi.htmlWhat you will need to do:
Geolink plugs into the sat port on the side with "SYS". ESC telemetry for HW plugs into the sat port on the ELE/PIT/AIL side.
RPM signal wire from the HW esc still goes into the middle 'pit' pin on ELE/PIT/AIL - this is for if you want to use the spirit governor, and also to be able to have RPM readings for telemetry.
The actual HW telemetry cable plugs into the port on the ESC where the fan would normally plug into. This means you will need to power the fan, if you are running one, from somewhere else (you may need to split power again, somewhere).
4649t signal wire goes into the "AIL' in on ELE/PIT/AIL.
You will need a Y splitter to split power from somewhere if you want the optiguard. Split power from the optiguard port or RUD so that you can power both the 4649T and give the spektrum multi adapter power for the satellite you will be adding. Swap the signal pin from one of the leads on the spektrum multi adapter the servo connector that ends up going into RUD since the signal goes in there.
NOTE: Read the manual for the spektrum mutli adapter. You will still need to use the regular satellite ports for binding the satellites, so the geolink and esc telemetry cables cannot be plugged in during binding. Once bound you can move the satellite to the new place with the adapter cable, and hook up the geolink and esc tele to the original satellite ports.
And there you have it, ESC Telemetry, GEOLINK, one satellite, the 4649t, and the optiguard. While the wiring sounds like a mess, there is a lot of stuff going on there. Imagine that on my nitros I have to split power several times to additionally power my RPM sensor and onboard glow ignitor.
