Rx-24 receiver circuit diagram for use with a DCC Interface module.
You no longer need that big transmitter anymore! The programmable OMNI Tx-4.0
handheld transmitter will control your garden railway electric locomotives perfectly
from the palm of your hand. An Omni Rx-4 or 24 receiver with be needed to work
with the OMNI Tx-4.0 transmitter in DCC mode, but the Tx4.0 will also operate our
standard r/c Rx2 or Rx22 receivers installed in analogue DC models.
2.4GHz gives perfect glitch free control for up to 800 metres range with no
obstructions.
The Regulator Knob controls speed and direction. Forwards to the right, reverse to
the left. Cruise control is possible by turning off the transmitter while the train is run-
ning. Turn back on to instantly regain control. A controlled E-stop is achieved by
moving the knob fully to the opposite direction. A maximum of 2 seconds from full
speed.

Centre Stop.
Whilst moving, if a quick
stop is needed, move
the knob fully to the op-
posite direction for a
controlled E-stop (Max 2

This knob is also used
when reprogramming the
top buttons.

Binding Procedure.
Now simpler than ever!
1. Turn on the Receiver (or the model, if it’s
already fitted inside) then….
2. Hold down black buttons 1 and 3, then turn
on the transmitter
3. Successful binding is indicated by LED 2
going ON.
4. Release the two buttons and the job is
done. LED 1 goes solid to indicate that the
Transmitter and receiver are linked.
13Re-Programming the top Buttons for momentary or
latching operation
(All are momentary by default, except F1 on Rx24 DCC re-
ceivers, which is latching by default)
This procedure must be started within 20 seconds of turning on the receiver, there-
fore start with the transmitter off and the model switched on. See our website for a
link to video instructions.
First you must put the transmitter into Button Calibration Mode :-
1. With the Transmitter turned Off. Press and hold button 1 and 2.
2. Turn the Transmitter On.
3. Both LED’s will start flashing, then go solid, indicating successful entry to
the Button Calibration mode. At this point, release the two buttons. LED 2 now
starts flashing.
Once in Button Calibration Mode, there is no exit except Transmitter power Off.
CHANGING BUTTONS FROM MOMENTARY TO LATCHING
The Regulator control knob is used to change the function of a button from latching
to Momentary or Vice Versa. Turn it in the desired direction and the given button
will be changed.
Fully anti-clockwise = Momentary Fully clockwise = Latched
Press the required buttons to save the setting for a function.
For example if you want function 12 to be latching, turn the regulator fully clockwise
and press both shift buttons followed by button 3.
You can now select another button to change, or turn the transmitter off.

Programming the OMNI system to suit your needs.
Your OMNI transmitter and receiver comes to you all pre-set and ready to run DCC
electric trains. Forwards and Backwards on the regulator knob and the three top black
buttons can activate sounds via the DCC interface module. Normally there should be no
need to change these settings, However...
The OMNI R/C system is ideal, in that when you wish to re-program it to suit the special
needs for a particular loco, it is not the transmitter you are re-programming, but the re-
ceiver in the loco. The Transmitter tells the receiver what is expected of it in the future,
and it is the receiver that remembers it. In this way, one OMNI transmitter can control
many different types of locos, each with its own very different requirements.
It is possible to change all or just one of the functions from Momentary to latching.

When the batteries in the handset get too low for reliable operation, both LED 1
and 2 start flashing together. Replace them with quality alkaline AAA cells for the
best results,
