XT-Module to be monted under the layout

Basics DC-Car-XT

When it is set to: Evaluation of the battery test

Side or bottom transmitter: DC08 incl. resistor
  • Sorting out vehicles with an empty battery to reach a charging station (in conjunction with software fully automatic charging is possible).

Other options: see XT-Module

Side or bottom transmiter: DC07 needs a 100 ohms resistance


Infrared transmit and receive

As sensor we require a photo transistor.
It can be installed:

  • In the delineators post
  • In the street as manhole cover
  • As a sensor in a stationary vehicle
  • hiding in trees, shrubs, buildings,...


Values for the car decoder

CV25 = 1 Transmitting from the back (via the IR LEDs for distance control) or
CV25 = 4 Side or bottom transmitter
CV26 Function of the vehicle with battery empty
CV27 = 2 or 10 battery test turned on
CV28 = 50 (1.2V) or 100 (2.4V) or 130 (3.6V battery)

DC-Car-XT-Modul

Delineator post with FTR
Position of side transmitter
  1. Switching a 3-way servo turn out
  2. Switching a contact to ground / GND
  3. Transmitting a freely selectable DC Car Infrared command


You can choose whether the respective function is resetted after a certain time or by triggering a reed contact.

Connection of XT-Module

Connection Description

DC voltage of 5V / 500mA via screw terminal block or the mini USB port.

  • LED indicator

Green LED: 5V operating voltage available. Blue LED: received valid signal.

  • Photo transistor (+ and -)

Note: Reverse marked as an LED.

  • Servo connection

For direct control of a servo on the XT module. Please pay attention to the correct connection sequence, as these might vary with the different manufacturers.
