Micron Radio Control Tx22v2 User Information

Tx22v2 User Information
Tx22v2 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 a toggle switch and push button that can be used for controlling
lights, sound cards, couplers, etc. Tx22v2 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 DT 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 Tx22v2 toggle switch is not used for direction, it is available for
controlling auxiliary functions such as lights and sound modules.
Tx22v2 may be used for receiver programming using the toggle switch to
step through programming levels. Programming details for each receiver
may be accessed from the web page for the receiver.

Technology

Tx22v2 uses the 2.4GHz band which requires no frequency channel control and is very resilient
against interference. All radio frequency components are contained on an internal module. There
are no user adjustable parts on this module and it should not be modified.
Tx22v2 is compatible with all DSM2 receivers; this includes Micron and Deltang receivers.
Any number of receivers can be bound to your Tx22v2 but only up to twelve, bound to different
Selecta positions, should normally be switched on at a time to operate them independently.
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
Toggle channel 3 (up or forward = channel high, down or reverse= channel low)
switch:
Bind button: channel 5 or none if inertia configured as channel 5) (up = channel high, down =
channel low)

Battery

Tx22v2 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.

image_width => '150px'); } To replace the battery:
Make sure that the power switch is off (up) before adding or removing a battery.
Remove the lid at the bottom rear of the case by sliding it downwards. When Tx22v2 is new this will
require a bit of effort to slide it past the retaning 'click'. The image at the right shows the case rear with
the battery lid removed.
Remove the battery from the compartment and pull the battery clip off the terminals. Replace the clip
