The Spektrum SPM9747 DSMX SRXL2 receiver is used in addition to compatible Spektrum receivers to ensure signal stability using the patented Spektrum MultiLink technology, which prevents signal loss and polarization over long distances from the transmitter.
The SPM9747 SRXL2 spectrum is compatible with receivers that use optional SRXL2 receivers (4-pin connector). It is equipped with an integrated antenna design inside the housing, for easy installation and reliable performance.
SRXL2 is a powerful communication protocol based on a rich UART serial interface that supports two-way communication between the radio system and the flight control unit. It supports telemetry and configuration of control unit parameters (Forward Programming, VTX Setup and Text Gen Programming), one signal wire at a time. SRXL2 is not backward compatible with SRXL.
The optional SPM9747 DSMX SRXL2 receiver is equipped with an integrated antenna design, which simplifies installation and eliminates damage as was the case with the cable wires of external antennas.
The SPM9747 DSMX SRXL2 is not compatible with receivers that use 3-core wires for optional receivers. The main receiver must be compatible with the 4-wire SRXL2 optional receiver. The SPM9747 is only compatible with receivers that include SRXL2, such as the AR637T and AR6610T.
