Pixhawk 2.1 and RSSI signal from Dragonlink V2

Hello everyone.

Could anyone confirm if I did the correct installation of the dragonlink?

  1. Wiring (photo 01: https://1drv.ms/u/s!Aq4y6Yu1sPdmjH2ORBH-AwY3rUj9 )

1.1 Connected 12-channel (PPM) on the RC IN pin (Pixhawk 2.1)
(all channels working ok, flights already performed and no problem here)

1.2 I connected the receiver RSSI pin on the SBUS pin (Pixhaw 2.1)
(I just connected signal and ground, I’m not sure it’s possible to send 5.3v from the receiver to SBUS input)

  1. Mission Planner:

RSSI_ANA_PIN = 103
RSSI_CHAN_HIGH = 2000
RSSI_CHAN_LOW = 1000
RSSI_CHANEL = 0
RSSI_PIN_HIGH = 3.3v
RSSI_PIN_LOW = 0.2v
RSSI_TYPE = 1 (AnalogPin)

(I made several attempts to configure by AnalogPin and the PWM channel, but in none of the attempts the signal was 100%).

With this configuration, the RXRSSI appears 85% in the mission planner (in the tower RSSI application does not appear). Is that correct?
