Micron MR603 Quick Start Manual

Micron MR603b Quick Start Guide
This guide is designed to get you started with MR603b as quickly as possible. More information can be
found in the user manual - http://micronrc.uk/mr603b.
MR603 receiver is 2.4GHz DSM2/DSMX receiver, with 3A max brushed speed controller, for use in
larger scale model rail locomotives and road vehicles. It is compatible with any Spektrum DSM2 or
DSMX transmitter including all of the Micron
If purchased with a transmitter, MR603b will be bound to the transmitter and is ready for use;
otherwise, it requires binding to your transmitter. Once bound, the transmitter should be switched on
before the MR603b. If the transmitter is not switched on, MR603b will automatically enter bind mode
10 seconds after switch on; it may also be configured to bind only manually using pads P5 and P6.
Usage
Do not bend the receiver circuit board
Connect the positive and negative input pads to a suitable battery or power supply, via a on/off
switch in the positive lead. A resettable fuse must be placed in the battery positive lead to
protect the battery in the event of a wiring or component fault.
Connect the 'M' pads to your vehicle motor, removing any connections to track pickups. If your
loco has suppression capacitors or chokes fitted, leave them in place. It is not usually necessary
to fit suppression components if your loco do not already have them. Contact Micron if you do
experience symptoms of motor noise interference.
Connect any auxiliary circuits to the F and P pads; the 3.3V pads may be used for powering
auxiliary circuits with a maximum of 20mA per pad. F pads are switches, open circuit when off
and connected to negative when on.
Protect the receiver board before applying power for testing. It must not be allowed to touch
anything metal. If MR603b was purchased with the heatshink cover supplied loose, slide this over
the circuit board.
After switching on:
the CPU LED (at side of receiver board) will emit a rapid flash followed by a flash count
corresponding to the selected configuration (default = 1), shown twice
the CPU LED will then slow flash while MR603b is searching for its bound transmitter; if not
already bound, approx 10 seconds later the receiver will go into bind mode and the RF LED
(near aerial on opposite of board to CPU LED) will show a rapid flash; switch your transmitter
on in bind mode and the RF LED will show an irregular slow flash eventually lighting
continuously.
When bound:
the CPU LED will be on to show receipt of good data from the transmitter
the RF LED will be on and may flicker due to electrical (e.g motor) noise, signal fades caused
by reflections, interference from WiFi or Bluetooth signals, or overloading from the
transmitter (this will happen if the transmitter is too close)
the CPU LED will show a repeated double flash when deselected (transmitter Selecta switch is
moved)
the CPU LED will show a repeated 5 flash if the low voltage cutoff has triggered
After testing, apply the heatshrink cover if not already fitted.
Fix the receiver in place and route the aerial so that the last 30mm can 'see' the transmitter for
best range - e.g. by routing through a hole in the vehicle body. The aerial should not be cut short
or made longer as this will affect operation. It is important to perform a range check after
installation to ensure you have full control of your loco/vehicle at all positions around the layout.
Double sided foam-cored sticky tape is ideal for mounting the receiver.
