XT-Modul-battery test

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)

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.

Pin assignment

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.

• IR-LED Connetor (with out resistend)
  

To send one command to the DC-Car

Left       right XT-Modul The Xt-Modul send one command, indecator right, and the Servo go to right for a few sekunds.
