Micron MR603 Receiver Programming - v1.2

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.

1-10 = R/C Channel		Direction
1-10 = R/C Channel		One control for throttle (0 .. 100%)
Second control for direction
(prog: 1,1,2,1,3 = Menu1, H1, low-off, R/C chan 1, R/C chan 3
11 = ESC Num3 = Not used
11 = ESC Num4 = Motor start power
min-power		0-10 = Tens (x10)
(0-flash = 0)		0-9 = Units (x1)
(0-flash = 0)		Minimum power level, the motor will jump to this power when the throttle is opened.
(0% for full power range)
(eg: 1,1,4,2,5 = Menu1, H1, min power, 25%)
11 = ESC Num5 = Motor max power
max-power		0-10 = Tens (x10)
(0-flash = 0)		0-9 = Units (x1)
(0-flash = 0)		Maximum power level
(100% for full power range)
(eg: 1,1,4,8,0 = Menu1, H1, max power, 80%)
11 = ESC Num6 = Motor reverse
reverse		1 = Normal
2 = Reversed		Reverse motor rotation
11 = ESC Num7 = ESC PWM
pwm		1 = 16kHz*
2 = 8kHz
3 = 4kHz
4 = 2kHz
5 = 1kHz
6 = 500Hz
7 = 250Hz
8 = 120Hz		Set the speed controller PWM frequency, the default setting is 16kHz. Lower PWM values give increased slow speed torque at the expense of motor heating
11 = ESC Num8 = Motor soft start/stop
- inertia
soft-start		Acceleration
1 = immediate
2 = 0.25s
3 = 0.5s
4 = 1s

1,1,8,1,1 = no inertia, motor speed immediately follows the throttle control
1,1,8,4,1 = accel and decel over 1s
The default is immediate; 0.25s or 0.5s will reduce ESC heating for motors
with significant BEMF.
2 = Servo Configuration1-6 = P1-P61 = Normal Servo
servo		1-10 = R/C Channel1 = normal speed
2-6 = slow motion		 Servo PPM signal on any 'P' pad. Default is full throw from full stick movement; servo travel and reversing can be adjusted using level3 = 7. Slow motion times are roughly equal to the number of seconds for end to end rotation (for an 'average' servo).
21-6 = P1-P62 = Not usedPlaceholder for offset servo
21-6 = P1-P63 = Not usedPlaceholder for toggled servo

Idle on
P=3.3V, F=closed
4 = ch low off
5 = ch mid off
6 = ch high off		1 R/C channel can control up to 3 outputs, momentary = non-latching.
eg: 3,4,1,5,1 = P4, On only when Ch5 is low

2 = ch high toggle
Start on
P=3.3V, F=closed
3 = ch low toggle
4 = ch mid toggle		1 R/C channel can control 1 or 2 outputs, each control action toggles the output on/off.

4 = <1s 2.0s momentary on
Channel low
5 = <1s 0.5s momentary on
6 = <1s 1.0s momentary on
7 = <1s 1.5s momentary on
8 = <1s 2.0s momentary on		 1 R/C channel can control 1 or 2 outputs with either momentary with a selection of on times or latching action. Momentary or latching selection is based on the time that the control is away from mid value (centre): <1s gives a momentary on, >2s latches; if the output is latched on the momentary action is disabled. All outputs start off (P=0V, F=open).

starts an indicator flashing, movement of the steering channel away from
centre cancels the indicator. A > 2s left/low operation of the
activating channel starts both indicators flashing together as hazard lights.
Options 3 & 4 are for a simple flashing lights and are toggled by a left/low
operating of the activating channel

buffer-stop		Time to stop: 1-6 = 1-6 secondsReactivation delay:

LVC sleep is triggered by Low Voltage Cut (if enabled)
44 = Failsafe / Cruise
Failsafe		Time to stop after signal loss:
1-4 = 1-4s
5 = sleep time		 Time to kill outputs after signal loss. Use 'Sleep time' (level 3 option 5) for 'cruise control' with transmitter switched off.
45 = Emergency stop

(eg: 7,5,2,3,6 enabled using Ch3 low with 6s delay - i.e. Ch3 must be low for at least 6s to trigger.)
2 = ch low to stop
3 = ch high to stop		1-10 = R/C ChannelTime to stop:

Selecta		1 = stop
2 = continue		Action when deselected: 'continue' or 'stop':
continue - ESC continues at the last throttle setting.

the default is 'continue'.
410 = Auto-light control
auto-lights		1 = Disabled Enable/disable the auto-direction outputs using an R/C channel. When this control is enabled, the initial state of auto-lights is disabled (i.e. off). Any other function mapping of the R/C channel remains - e.g. output on/off switching.
2 = Enabled1-10 = R/C Channel1 = toggle when ch low
2 = toggle when ch high
3 = momentary when ch high

414 = Show Firmware Version
Version		 Show the firmware version by flashing the LED (and LED2 if enabled). Firmware versions are 2 numbers: major and minor (e.g. 1.2). 0.5s of rapid flashing is shown first, followed by a flash count for the major number, a pause and then a flash count for the minor number. A zero is shown as a very brief flash, much shorter than the normal flash. The pattern is repeated until the receiver is switched off.
5 = Radio Configuration1 = Binding
Bind		1 = DSM2/DSMX Protocol1 = auto
2 = manual		Choose auto or manual bind. The pins/pads for manual bind are specified in the receiver manual.
