SPECIFICATIONS

Spektrum SRXL2

The SPM4650 uses SRXL2™ to communicate with flight controllers. SRXL2 is a serial communication protocol (a bi-directional data link, one signal wire can communicate all control and telemetry). Previous Spektrum serial receivers were based on 1st generation Spektrum remote receiver protocol, which is not compatible with SRXL2.

Installation Instructions

Wiring for the receiver can be directly soldered to the SPM4650 or the included 4-pin connector can be soldered onto the receiver and used to make the connection to the flight controller.

Connect the receiver to your flight controller as shown in the diagram below.
Install the active portion of the antennas (the exposed section at the end of the antenna wire) as far as possible from metal, carbon fi ber, and wiring.

WARNING: Do not kink, cut or damage the antenna wire. The antenna is made of a coaxial wire; if the outer sheath becomes damaged, the receiver will not work properly.

Installation Instructions
