Tx10 User Information

Tx10 is a simple hand-held wireless transmitter intended to control one model railway locomotive engine. It has a large knob for forward/reverse throttle control and a push button for receiver binding. Tx10 is ideal as a basic, entry-level transmitter for modellers who don't need a more complex controller. The bind push button can also be used to operate a whistle or horn if you have a sound card.

Tx10 cannot be used for Deltang receiver programming. If you need to program a receiver, a Prog3 or Prog4 will be required.


throttle:channel 1
bind button:channel 5


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.

To replace the battery:

On / Off Push Button

The LED lights continuously when the transmitter is on and flashes when Tx10 is in bind mode (see below). It is best to switch the transmitter on before the receiver. If a receiver is switched on with Tx10 off, it is likely to enter bind mode with rapid flashing of the LED on the receiver board. If you did not intend to bind, switch the receiver off, then switch Tx10 on followed by the receiver.

Speed / Throttle Knob

Off/Stop is in the centre of rotation when the white dot is pointing toward the top of the transmitter. You will feel a 'click' as the knob is centred. Rotating the knob to the right (clockwise) should move your loco forwards. If it goes in reverse, you need to swap the two wires connected to the motor in your loco.

Bind Button

Note: holding the bind button for longer than 20 seconds will result in strange things happening (see Calibration).

If a receiver has not previously been bound, it has to be 'paired' with the transmitter. Binding is only required once per receiver.

  1. Put your receiver into Bind mode (if a Deltang Rx4 or Rx6 receiver, switch it on and wait for the LED to flash fast).
  2. Press and hold the Bind push-button on the transmitter.
  3. Switch the transmitter on by pushing the Power button and then release the Bind button.
  4. Binding is complete when the receiver LED stops flashing.


All ready-to-use transmitters are calibrated as the final manufacturing step. This sets the throttle control centre position and normally only needs to be done once. If you suspect that the throttle control is not operating correctly or you have replaced any of the internal components (e.g. throttle potentiometer), your transmitter may need calibration.

If the bind button has been inadvertently held down for longer than 20 seconds, the previously stored calibration data will have been overwritten and you could find that the throttle control behaves strangely.

To perform calibration:

The throttle control centre position is now calibrated.
