JR RG731BX 7-Ch DMSS X-Bus Supported Receiver


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.

  • With DMSS, cross modulation is restricted. This high sensitivity receiver is not easily affected by inter-modulation interference.
  • DMSS telemetry system is capable of feeding back information such as receiver battery voltage.
  • The use of both coaxial antenna and a remote antenna, secure and precise communications link is assured.
  • Receiver operation is confirmed by way of LED's.
  • Supports transmitter sensing of fail safe.
