I would appreciate some advice on connecting the following system.
Spirit Pro
Hobbywing Platinum 130A HV V4 (internal BEC)
SPM4649T Telemetry Receiver
SPM9645 Satellite Receiver

Installation is on a Trex 700 and my Tx is a DX9.

This is what I understand so far :

Spirit Pro
SYS
CH0
CH1 Pitch Servo
CH2 Elevator Servo
CH3 Aileron Servo
CH4 Rudder Servo
AUX2
AUX1 HW ESC Throttle Signal Cable
RUD Red/Brown wires to SPM4649T Bind/Serial port (using Jeti integration cable)
ELE/PIT/AIL Orange wire to SPM4649T Bind/Serial Port (using Jeti integration cable)

HW ESC
Programming Port connected to Spirit primary satellite port using Telem UNI cable

SPM9645 Satellite
Connect to secondary satellite port on the Spirit

Questions (if the above is correct) :
1) What do I do with the BEC Output cable (Red/Brown) from port -+R on the HW ESC (CH0 or Aux2 on the Spirit) ?
2) What do I do with the RPM Signal wire (Yellow) from port -+R on the HW ESC ?
3) Do I use the Laps/Volts/RPM port on the SPM4649T ?

Many thanks

Michael

Hello,

your wiring seems to be correct.

1) AUX2 port or CH0 port can be used.
2) No need to connect it if Governor from the unit will be unused.
3) This depends on you. You can connect BEC voltage there - this will allow BEC voltage measurement.

Many thanks for your help with this.

You can see here how I wire up to get RX voltage in the telemetry:
