Further special features will provide a smooth operation not only for PC and Model Railway Software controlled Model railway layouts.

• With a jumper (“Short Report”) can be the DigitalBooster DB-4 set to the function that a short circuit will be reported to the command station to initiate a switch-off of all boosters or switching off the single track section where the short circuit was reported from.

• With the jumper (“Auto Go”) can be the DigitalBooster DB-4 set to the function that the unit will continuous check every 5 sec. if a short circuit will be present. If the short circuit will be solved the DigitalBooster DB-4 will supply the relevant track section with current again.

• With a further Jumper is it possible to set the maximum digital output current of the DigitalBooster DB-4 to 2,5 or 4,5 Ampere.

• The DigitalBooster DB-4 provides the possibility to switch-OFF and -ON the current at the tracks of the layout by external push buttons. This can be helpful if the stop button of the command station will be at a far distance by a critical situation.

• If the model railway layout will be controlled by a PC-Model Railway Software is it possible to switch the track digital current ON or Off via the Digital Booster DB-4 if required with the Märklin-Motorola- or DCC-Commands.

• Integrated WatchDog-Function: If the WatchDog-Function will be activated by the model railway software, the DB-4 will control additionally the PC and the command station. If the PC or the model railway software will not get in contact to the DB-4 every 5 seconds with a switch command is the software of the PC- or the command station crashed and the model railway software has no longer control about the model railway layout. To avoid that trains will travel non-controlled the DB-4 will switch in this case the rails off from power supply and all trains will be stopped.

• The DigitalBooster-DB-4 provides a Feedback-Output for the Booster Management of the Model Railway Software to provide a report to the model railway software if presently a current will be supplied to the tracks or if the tracks at the booster section will be current free.

• If required will be the DigitalBooster DB-4 able to create within the DCC-Setting the RailCom ®* blanking pulse.

Kabel Booster 1m	€ 6,90
For a connection via the CDE-Booster bus e.g. Lenz Digital plus, Intellibox, IB-BASIC, IB-COM, TWIN-CENTER, EasyControl, ECoS and Commander.
There is no special booster bus cable required because the connection will be made individual by three single wires via the CDE clamps.
For a connection via the Roco-Booster bus with Roco 10761/10764, Fleischmann 680801, multiZENTRALEpro and several DigitalBooster DB-4 between each other.
Kabel Roco 1m	€ 6,90

• Order code:
