Micron Radio Control Tx22X User Information

Tx22X User Information

Tx22X is a hand-held wireless transmitter intended to control up to 12
model railway trains. It has controls for Speed, Inertia and Loco selection
plus toggle switches and push buttons that can be used for controlling
lights, sound cards, couplers, etc. Tx22X is available in 2 versions: with
and without a detent on the throttle control:
the detent version has a mechanical 'click' at the centre of the travel
and is intended for use with receivers configured for fwd/rev control
on the throttle channel,
the no-detent version is for use with receivers configured for full-
range throttle and direction control using the toggle switch.
When the Tx22X S1 toggle switch is not used for direction, it is available
for controlling auxiliary functions such as lights and sound modules.
Tx22X may be used for receiver programming using the S1 toggle switch
to step through programming levels. Programming details for each
receiver may be accessed from the web page for the receiver.

Technology

Tx22X uses the 2.4GHz band which requires no frequency channel
control and is very resilient against interference. There are no user adjustable internal parts and it
should not be modified.
Tx22X is compatible with all DSM2 receivers; this includes Micron and Deltang receivers.
Any number of receivers can be bound to your Tx22X but only up to twelve, bound to different
Selecta positions, should normally be switched on at a time to operate them independently. The
Selecta function is available only on Micron and Deltang receivers.
Range is suitable for indoors and small outdoor sites; the outdoor free-air range to a model rail
receiver is at least 50m. Range indoors is affected by building construction materials, furniture,
people and receiver installation.
Control knob, switch and push button actions are transmitted as separate R/C 'channels' which
must match the receiver configuration:
Throttle: channel 1
Selecta: channel 2
Inertia: internal use for inertia or may be reconfigured to control channel 4 or channel 5
S1 switch: channel 3 (up or forward = channel high, down or reverse= channel low)
S2 button: channel 4 (up = channel mid, down = channel low)
Bind Button: channel 5 (unless inertia is configured to control channel 5) (up = channel high, down =
channel low)
S3 switch: channel 7 (up or forward = channel high, down or reverse= channel low)

Battery

Tx22X uses a PP3 9V battery, preferably Alkaline or NiMH / Lithium rechargeable. The
maximum working voltage of the internal electronics module is 10V and there is a
protection diode wired in series with the battery lead. This allows the battery voltage
to be up to 10.7V. If the battery voltage is above this value, the internal regulator
will shut down and the transmitter will not operate.
