Spektrum SRXL2
The SPM9747 uses SRXL2 to communicate with receivers. SRXL2 is a serial
communication protocol using a bi-directional data link in which one wire can
communicate all control data. Previous Spektrum serial receivers were based
on the Spektrum remote receiver protocol, which is not compatible with SRXL2.
The SPM9747 is only compatable with SRXL2 receivers such as the AR637T
and AR6610T.
