Micron MR6xx Receiver Programming - v1.0
Micron MR6xx receivers implement a common programming interface which allows functionality to be changed using most Micron model rail transmitters or a joystick Tx. Each row in the table below describes a 5 number sequence (levels 1 to 5) which is used to modify a feature's behaviour - e.g. change the ESC from centre-off to low-off throttle; set an auxiliary output as servo, on/off, or auto-direction light.
A transmitter encodes each control (throttle, toggle switch, push button, etc.) as a number in the range 0..1024 and transmits them in the radio signal as separate R/C channels. The mapping between transmitter controls and R/C channels is described in the user manual for the transmitter. Throttle is usually channel 1, Selecta (if used) is channel 2, the bind button is channel 5, and so on.
Motor and servo outputs use the channel value directly to provide a proportional response to transmitter control changes. Switched outputs usually divide the R/C channel range into 2 or 3 positions: low, mid and high where low is a channel value less than 250, high is greater then 750 and mid is 511 +/- a small delta. The transmitter user manual describes the control positions corresponding to low, mid and high and the programming table shows how these low, mid and high values are used to switch the output.
