2. DB-4 connection to the Digital-Command-Station or to other

Booster:

The galvanic separated boosterbus connections enables the application of the
DigitalBooster DB-4 in connection with several command stations by using the 5­poles Boosterbus, the CDE-Boosterbus or the Roco-Boosterbus.

The DB-4 is no Booster-Adapter. A change of the bus-system is impossible. The
booster-bus used for the connection of the first DB-4 to the digital command
station has to be used furthermore.

The below table indicates the possible connections to the available command

direction of the cable shows to the bottom. For the Märklin Booster 6015 is the
correct position of the Boosterbus-Cable showing to the top.

The second plug of the boosterbus cable has to be connected at the DigitalBooster
DB-4 to the pin bar ST1 with the marking “IN“.
Please attend that the white single wire of the 5-poles cable corresponds to the
white marking at the pin bar ST1.
The plug position of the 5-poles boosterbus cable is correct on the DigitalBooster
DB-4 if the twisted cable has a direction away from the booster.

If a following booster shall be connected with a 5-poles boosterbus cable to the

DigitalBooster DB-4 this has to be done via the pin bar ST2 (“OUT”).
