Micron MR001c Receiver Programming - v1.0

PDF

This page contains programming information for firmware versions shown in the page title, information for other versions can be found via /mr6xx_versions.

Micron receivers implement a rich set of features with a common programming interface that 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 throttle from centre-off to low-off behaviour; set an auxiliary output as servo, on/off, or auto-direction light. Each row also contains a brief explanation of the function accessed by that row and a link to more detail in the features page.

The value for each level of a programming sequence will be indicated by a repeated flash pattern on a receiver's LED. For example, the value 3 is displayed as a sequence of 3 flashes followed by a pause (this is called a 3-flash in receiver and transmitter user manuals). Where appropriate, a value of zero is displayed as a very short flash followed by a pause.

Many table rows specify how a transmitter control is used to activate the receiver function; the row specifies (usually at level 4) a R/C channel. Transmitters encode 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.

Receiver outputs use the channel value directly to provide a proportional response to transmitter control changes. Switched outputs 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 than 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 control the receiver output.

For specific information on how to place a receiver into programming mode, see the receiver's user manual. See the transmitter's user manual or Receiver Programming for information on how to use a transmitter for entering a program sequence.

(1 ch: fwd/rev)
esc-centre-off		Throttle
1-10 = R/C Channel		 Forward and reverse with one control, off at control centre (-100% .. 0 .. +100%). Output must be a 'Throttle Servo' and the purpose of this setting is for control of the auto lights and where the throttle is positioned for emergency stop and failsafe.

11 = Throttle Num2 = Low off

esc-low-off		Throttle
1-10 = R/C Channel		Direction
1-10 = R/C Channel		 One control for throttle (0 .. 100%) and another for direction. Each channel goes to separate outputs, the throttle must be a 'Throttle Servo', direction is a 'Normal Servo'. The purpose of this setting is for control of the auto lights and where the throttle is positioned for emergency stop and failsafe.

6 = +125% (0.6ms..2.4ms)

8 = +200% (0.3ms..2.7ms)		 Expand the servo throw range from the default 1.1ms .. 1.9ms (aka 100%) servo pulse width. The actual pulse width range will depend on the range of your transmitter's control. These fixed scaled values can be fine tuned using servi travel adjustment.
Beware: make sure that your servo can handle the increased range before connecting it.
