Micron MR001 Receiver Programming - v1.1

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.

11 = ESC Num4 = Not used
11 = ESC Num5 = Not used
11 = ESC Num6 = Motor reverse
1 = Normal
2 = Reversed
Reverse motor rotation
11 = ESC Num7 = Not used
11 = ESC Num8 = Not used
11 = ESC Num9 = Direction mode
1 = latching (default)
2 = stop when neutral
Set the throttle behaviour for low-off and split when the direction control is centred. The default is latching so that the vehicle direction stays the same until the control is moved to the opposite. This function allows the neutral / centre point to disable the throttle - i.e. a neutral gear effect.
11 = ESC Num10 = Auto light mode
1 = on when stopped (default)
2 = off when stopped
Set the auto light behaviour when the motor is stopped. The default is 'on when stopped' and should be changed to 'off when stopped' for road vehcles.
2 = Servo Configuration
1-11 = P1-P111 = Normal 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).
21-11 = P1-P112 = Not usedPlaceholder for offset servo
21-11 = P1-P113 = Not usedPlaceholder for toggled servo
21-11 = P1-P114 = Not usedPlaceholder for 2 chan servo mix
21-11 = P1-P115 = Not usedPlaceholder for 2 chan servo mix
21-11 = P1-P116 = Not usedPlaceholder for external ESC
21-11 = P1-P117 = Adjust Servo
1 = Toggle Servo Direction
2 = Adjust Servo Travel
Toggle servo direction or adjust travel using transmitter controls. If the pin is not currently configured as a servo, the receiver will exit programming mode at level 3.
21-11 = P1-P118 = Expand Servo Range
1 = normal range (1.1ms..1.9ms)
2 = +25% (1.0ms..2.0ms)
3 = +50% (0.9ms..2.1ms)
4 = +75% (0.8ms..2.2ms)
5 = +100% (0.7ms..2.3ms)
6 = +125% (0.6ms..2.4ms)
7 = +150% (0.5ms..2.5ms)
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.
3 = On/Off Configuration
1-11 = P1-P111 = Momentary on/off
1-10 = R/C ChannelIdle off

1 = ch low on
2 = ch mid on
3 = ch high on
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
eg: 3,6,1,5,3 = P6, On only when Ch5 is high

1 = ch low toggle
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.
(eg: 3,4,2,5,1 = P4, Start off, toggle when Ch5 is low)
(eg: 3,6,2,5,2 = P6, Start off, toggle when Ch5 is high)
31-11 = P1-P113 = Dual Action Latching
1-10 = R/C ChannelChannel high
1 = >2s toggle
2 = <1s toggle
Channel low
3 = >2s toggle
4 = <1s toggle
1 R/C channel can control 1 to 4 outputs. Output selection is based on the time that the control is away from mid value (centre). All outputs start off (P=0V, F=open).
31-11 = P1-P114 = Flash or Latch
1-10 = R/C ChannelChannel high
1 = <1s 0.5s momentary on
2 = <1s 1.0s 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).
31-11 = P1-P115 = Auto Lights
1 = Forward
2 = Reverse
3 = Brake
Link output ports to the speed controller status. See 7,7 for setting brake light on time and 3,x,10 for setting the behaviour of the forward and reverse lights when stopped (default is on when stopped and should be changed to off when stopped for road vehicles).
31-11 = P1-P116 = Left Indicator & Hazard Light
1-10 = R/C Channel
1-10 = R/C Channel
Indicator and Hazard Lights (level 3 = 5 or 6). A < 1s operation of the activating channel (high/left=left, low/right=right) starts an indicator flashing, movement of the steering channel away from centre cancels the indicator. A > 2s high/left operation of the activating channel starts both indicators flashing together as hazard lights.
There may be only one left and one right indicator pin.
31-11 = P1-P117 = Right Indicator & Hazard Light
See previous.
An attempt to set right indicator without first setting a left indicator will result in a rapid CPU LED flash error.
31-11 = P1-P118 = Output Grouping
0-9 = Group ID
(0-flash = no group)
1 = Exclusive Group P or F logic outputs to co-ordinate behaviour. The default is no grouping.

1 = LED2
1 = LED2 DisabledAny output can drive a LED to mirror the on-board LED.

2-flash: enabled but not after Rx is deselected (Selecta) or Tx is switched off (Cruise Control)

3-flash: enabled for Selecta and Cruise Control

4-flash: over-rides any other function on this pin (e.g. auto lights).
2 = LED2 Enabled (not deselected or cruise)
3 = LED2 Enabled when deselected or cruise
4 = LED2 Always
1-11 = P1-P11
42 = LVC
1 = LVC Disabled
2 = LVC Auto
Enable or disabled low voltage cut-off.
2-flash = LVC enabled with auto threshold,
3-flash = LVC enabled with manually set threshold.
Levels 4 & 5 only apply to manual threshold.
3 = LVC ManualManual threshold (volts):
4-10 = 4-10V
Manual threshold (tenths):
0-9 = 0.1-0.9V
43 = Sleep
Time before sleep:
1-6 = 1-6 hours
7 = never
LVC sleep:
1 = No
2 = Yes (5 minutes)
Inactivity timeout (1-6 hours)
LVC sleep is triggered by Low Voltage Cut (if enabled)
44 = Failsafe / Cruise
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
1 = DisabledManual trigger stop over radio
(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:
1-6 = 1-6s
46 = ESC Arming
1 = DisabledArm the ESC only when the throttle is in the off position. Enabled by default. THINK CAREFULLY before you disable this feature.
2 = Enabled1 = H1
47 = Brake On Time
1-6 = 1-6sThe time that the brake light stays on after stopping. The default is 1s.
48 = Selecta
1 = DisabledEnable or disable the loco selection feature which is compatible with all transmitters that have a Select switch. All transmitters stocked by Micron use R/C channel 2 for Selecta.
2 = Enabled1-10 = R/C Channel
49 = Deselect Action
1 = stop
2 = continue
Action when deselected: 'continue' or 'stop':
continue - ESC continues at the last throttle setting.
stop - throttle smoothly closes
the default is 'continue'.
410 = Auto-light control
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 ChannelStart off
1 = toggle when ch low
2 = toggle when ch high
3 = momentary on when ch high
Start on
4 = toggle when ch low
5 = toggle when ch high
6 = momentary off when ch high
411 = Reset
Restore backed-up configuration or, if no backup, the factory configuration
412 = Backup Configuration
Create configuration backup to be restored with a reset. A backup should be saved whenever the Rx configuration is changed by programming or using a power on jumper.
413 = Select Configuration
Select Config
1-4 = stored configurationSelect one of the stored configurations, See the receiver documentation for details of each configuration
414 = Show Firmware 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 Configuration
1 = Binding
1 = DSM2/DSMX Protocol1 = auto
2 = manual
Choose auto or manual bind. The pins/pads for manual bind are specified in the receiver manual.
6 = Input
1-11 = P1-P111 = Buffer Stop Trigger
Time to stop: 1-6 = 1-6 seconds One P pad can be used as a trigger to stop the vehicle automatically by slowing to a stop. The throttle must be closed to restart. The trigger is enabled after the reactivation delay.
61-11 = P1-P112 = Stop & Reverse Trigger
Time to stop: 1-6 = 1-6 secondsfixed pause
1-6 = 4,8,15,30,45,60s
random pause
7 = 4-8s
8 = 8-15s
9 = 15-30s
10 = 30-45s
11 = 45-60s
12 = 60-120s (1-2m)
13 = 120-300s (2-5m)
14 = 300-600s (5-10m)
One P pad can be used to stop the vehicle automatically by slowing to a stop. The vehicle reverses at the same speed after the pause time. If the vehicle is manually restarted by closing and then opening the throttle during the pause time, the restart is cancelled.
61-11 = P1-P113 = Station Stop Trigger
Time to stop: 1-6 = 1-6 secondspause time
as above
One P pad can be used to stop the vehicle automatically by slowing to a stop. The vehicle continues at the same speed and in the same direction after the pause time. If the vehicle is manually restarted by closing and then opening the throttle during the pause time, the restart is cancelled.
61-11 = P1-P114 = Not usedPlaceholder for limit switch
61-11 = P1-P115 = Reactivation Delay
1-15 = 5 second increments Set the delay before an input trigger is reactivated after being actioned. The default when setting an input type is 10 seconds (level 5 = 2). This program allows the delay to be specified in 5 second increments: 1 = 5 seconds, 4 = 20 seconds, 9 = 45 seconds, 15 = 75 seconds. Resetting the input type (level 3 = 1..3) resets the activation delay to 10 seconds.
61-11 = P1-P116 = Input Enable/Disable
1-10 = R/C Channel0 = disable control
Start Enabled
1 = disable when ch low
2 = disable when ch high
3 = toggle when ch low
4 = toggle when ch high
Start Disabled
5 = enable when ch low
6 = enable when ch high
7 = toggle when ch low
8 = toggle when ch high
All automation features are enabled by default. This function allows a transmitter control to over-ride this by:
- disabling on receiver start
- disabling or enabling while running
The input type (options 1..4) must be programmed before this function. If the P port is not configured as input, an attempt to enter this program option will result in a rapid flash on the receiver LED.
The actuating R/C channel may also be used for other functions - e.g. to light an LED to show the enable/disable state of automation.
61-11 = P1-P117 = Input Enable Indicator
0 = disable
1-11 = P1-P11
This function allows a Rx output (F or P) to be used to indicate when the input is manually activated - e..g. to illuminate a LED. The program sequence is available only when the 'Input Enable/Disable' control has been programmed. Set the pin value (level 4) to zero to disable the indicator.
