Setup for using a JR DMSS Tx/Rx

XBUS Connects like SBUS
Always start with a reset/new transmitter model!
NOTE: If your JR transmitter is DMSS, continue here. If it is DSM2 or DSMX, follow the Spektrum instructions!
NOTE: You will use the 3-Pin to 4-Pin Male to Male cable provided to connect the JR DMSS Rx's XBUS to the FLEXF3. This is the same cable arrangement shown on page 15 of the manual for the Futaba connections. (Non-Telemetry)
These instructions supplement the printed manual. Please read the manual before proceeding.

CYPHER/Betaflight Settings

Use one of the Betaflight configuration tools to make these settings. Be sure to SAVE the configuration page after adjustments.

JR DMSS Transmitter settings:

XG14 Mode 2 transmitter and R731BX and R712BX Receivers used for validations. Choose a receiver with diversity and capable of JR XBUS MODE B.
