The all new X-Bus system uses JR's own serial bus data instead of PWM (Pulse Wide Modulation) to communicate with X Bus products such as servos. Control signals are sent in a serial manner to all channels, with individual servos recognising their own data from receiver.
Non X-Bus servos can still be used in conjunction with a channel decoder in serial connection, or plugged directly to the PWM ports of the receiver (avoiding the X-Bus port).
Never plug any non X-Bus device into the X-Bus system as a failure is sure to occur. On large models, JR's optional X-Bus power hub allows servos to receive a separate power supply.
JR's new X-Bus receiver is also able to be plugged directly into compatible helicopter FBL units, allowing a single connection between the receiver and FBL unit.
RG731BX has 7 ports for PWM and 1 XBUS port.
