Micron MR001d Quick Start Guide (from v1.9)
PDF
This guide is designed to get you started with MR001d as quickly as possible. More information can be found in the user manual - http://micronrc.uk/mr001d-info. We strongly recommend you read this document if you wish to change any of MR001d functionality.
If purchased with a transmitter, MR001d will be bound and ready for use; otherwise, it requires binding to your transmitter which may be any Spektrum DSM2 or DSMX transmitter including all of the Micron model rail transmitters. Once bound, the transmitter should be switched on before the MR001d. If the transmitter is not switched on, MR001d will automatically enter bind mode 5 seconds after switch on; it also be manually bound using a jumper plug on the P5/P7 signal pins.
Usage (top)
Binding (top)
To bind:
If the receiver LED does not come on solid (no flash) within 10-15 seconds, the bind process has failed. This can happen for several reasons and does not normally indicate a fault. If you get a bind fail, try again after moving the Tx and Rx slightly further apart or changing the relative orientation of the aerials. Binding is most reliable when no other 2.4GHz transmitters are turned on.
Connections (top)
MR001d has 7 sets of output pins which can be used for servos, speed controllers or LEDs for lighting. The pin sets, numbered from the top of the diagram below, are 0.1" pitch to take standard R/C plugs.
An additional 4 outputs are available via an optional JST-SH socket at the aerial end of the receiver. Although the connector has 3.3V and 0V pins, it cannot be used for powering a servo as the 3.3V pin is supplied from the on-board regulator which has insufficient current capacity for a servo.
A connector with 100mm leads is supplied when the JST-SH socket option is selected at purchase.
Throttle Modes (top)
The transmitter's throttle control is output on P1 (default configuration, may be changed by programming) to drive a regulator servo or an external speed controller. The throttle mode is used mainly to control how the directional lights operate and to close the throttle if the emergency stop feature is enabled or cruise control is disabled. Also, there will be no output from P1 until MR001d has received a valid stop throttle signal.
Power-on-Changes (top)
Some MR001d configuration changes may be done using one or more jumpers placed on the P1..P7 signal pins before the receiver is switched on. The LED will display a flash pattern corresponding to the selected change. The table below summarises the available changes and the associated flash patterns.
The changes all cycle though the flash counts while the jumper is installed. Each flash count is repeated once (i.e. shown twice) and then increments to the next, cycling back to 1 when the maximum is reached. When the desired flash count has been shown, removing the large jumper acknowledges the selection by showing a rapid flash. There will be a short delay between removing the jumper and the rapid flash due to the time taken to write the changes to permanent memory. The receiver should be powered off when the rapid flash starts. If you switch off before removing the jumper connection, the configuration is not changed. If you switch off after removing the jumper and before the rapid LED flash, the receiver data is likely to be corrupted and you should perform a reset.
It is recommended to do a backup after making any other changes (including any programming via a transmitter - see http://micronrc.co.uk/mr001d-progtable).
See the user manual for more details.
Servo Adjustment using Jumper Plugs (top)
Servo throws (low and high end points) and reversing can be configured in 2 ways:
Use of jumper plugs will be described here, see http://micronrc.co.uk/mr001d-info for details on how to use a transmitter to adjust servo throws.
WARNING: never place the small jumper across the positive (middle row) and negative (bottom row) pins. This will short the battery.
Use the small jumper plug to select a servo output to adjust. It is placed across the signal pin (top row) to be adjusted and the adjacent signal pin. For example, to select P1 (throttle), place the small jumper plug across signal pins 1 and 2 as shown in the image (the black connector in the image is the battery plugged into P4). The standard MR001d setup has servo outputs on P1..P5. If your receiver has servo outputs on P6 and/or P7, these may also be adjusted - P7 requires use of both small and large jumper plugs.
Steps:
The servo output is now selected. Jumper plugs are used on P6 and P7 (or P1 and P2 for adjusting P6 or P7) to reverse the servo or adjust the travel end points. Reversing or end point adjustment can be repeated as often as desired while the servo is selected. To stop the process, remove power from the receiver.
The small jumper plug is placed across signal pins P6 and P7 (or P1 and P2 if adjusting a servo on P6 or P7).
The servo direction will reverse each time the procedure is executed.
Servo travel end points can be increased or decreased using the large jumper plug on P6 (decrease) or P7 (increase) - P1 and P2 for servos on P6 or P7. The adjustment is done in small steps every ½ second and the LED flashes for each step.
To make an adjustment:
The LED will stop flashing and the servo will stop moving when the adjustment limit is reached.
When the increment or decrement jumper is removed, the LED will flash rapidly for 2 seconds while the servo offset is being saved. You may continue adjusting after the flashing has stopped.
