Connecting the LEDs

The function outputs of the decoder switch respective to the decoder

ground. For that reason you must connect the cathode (-) of the LED to

the function outputs.

Caution:

If you use light-emitting diodes (LEDs) you must always operate them via a

series resistor. LEDs are available in many different models. The series

resistor limits the current flow of the LED and will need to be calculated for

each model. Ask for the max. current rating when buying your LEDs.

You can connect several LEDs in parallel to each output. In this case

every LED must have a series resistor of its own. If you connect several

LEDs to one output in series, only one series resistor is needed.

LD-G-31: Connecting a loudspeaker

Use a loudspeaker as large as possible with an impedance of at least

8 Ohm. Decisive for the sound reproduction is the correct mounting of

the loudspeaker. The loudspeaker membrane should emit directly to the

outside, the other side into the inside of the vehicle which should be as

airtight as possible. If necessary, use a loudspeaker with a sound

cartridge. The larger the volume in the inside, the better is the

reproduction quality. Suitable for the mounting are e.g. the bottom of

the vehicle or the back of the driver´s cab.

Connect the loudspeaker to the points X1 and X2 of the decoder.

LD-G-33, LD-G-34 und LD-W-33: Connecting a SUSI module

The decoder has four soldering points for the connection of a SUSI

module. You will find the pin connection in the connection diagram for

the particular decoder.
