DC-Car-Booster

Function

A DC-Car-Booster sends the signals of a DCC control station to the IR LEDs.
Another way of transmitting (455 kHz) increased range is achieved. Theoretically, transmissoin is possible up to 7 meters.
In order to ensure that the IR LEDs can control a car they are mounted on the ceiling.

Diagram

F.i. 33 Ohm for 5 LED in serial or 220 Ohm for 1 LED
Standard 33 Ohm is fitted so please use 5 IR LED in serial.
As a result, 7 x 5 = 35 LED can be connected. That's enough for about 35 square meters layout size.

Operation

By DC-Car-Booster, the vehicles can be controlled over a longer distance.
It is operated at 12-16 volts AC or DC.
The digital input is connected to the track connection (main track) a DCC control station.
All outputs can be loaded with 1 Ampere.
At each of the 7 outputs a chain of up to 5 infrared LEDs can be connected, ie a total of 35 LED's
On the DC-Car-Booster is a control LED. This lights up when a DCC signal has been detected.
In cooperation with an Intellibox or Twin Center is lit permanently.
Together with other systems or in multiprotocol these may flash irregularly.
If the DCC signal fails, the booster sends a stop signal to all the cars and the indicator flashes.

To use the DC-Car Booster, an additional remote receiver must be installed in each vehicle.
By programming the CV21 this additional receiver is activated:

• No LongControlIR (LCIR) operation CV21 = 0
  

There are no signals from the LongControlIR received (LCIR).

• DC-Car-Booster CV21 = 4 |

The 'DC-Car-Booster' is easy connection to the track (main track) which is connected to the digital control station.

• DC Car - PC Transmitter CV21 = 24
  

'WARNING: The CV21 in the towing vehicle and the trailer Decoder must always have the same value. Otherwise, driving the trailer decoder stops working. 'In

CV programming disabled

There are no CV settings from the DC-Car-Booster transferred to the car.
This feature was removed for safety's sake, because it came to unwanted programming of vehicles using the same DCC address. A programming transmitted along the rails should only be made by an infrared transmitter (IR-LED) directly on the track or on the CV-Programmer.
But if you want to do without this feature can be added to ground of PIN 28 of the processor a bridge or jumper just has to be set on the board. Alternatively, you can also use a switch.

'NOTE: When you perform a reset, ALL vehicles in range of the transmitter back!'

Extension for booster or PC transmitter

300 px|right Since not 2 Booster may irradiate a car at the same time, the controller can be extended only by an amplifier.

For further 7 chains
with 5 LED
must be installed all odds.

To connect the modules to high-quality cables are used most shilded cable.
The lines of the IR LED should be with Litzekabel and as short as possible.
With bell wire (rigid wires) may falsify the data.
