Electronic Co., Ltd. All products enabled with Smart Port (including XJT module, XSR,X6R and X8R receiver,
new hub-less sensors, new Smart Dashboard, etc), serial port user data and other user input/output devices
can be connected without limitations for numbers or sequences at a high transmission speed.

SBUS/CPPM output (BLUE LED stay lit indicates R-XSR in SBUS mode, otherwise in CPPM mode)
How to switch SBUS and CPPM signal: Long press the F/S button on the receiver for 4 seconds, the BLUE LED
will flash three times, indicating the switch is completed.
R-XSR supports the redundancy function for the master and slave receivers. The master receiver receives SBUS
signal from the slave receiver. The master receiver can be R-XSR, and the slave receiver can be receiver with
SBUS output.
