- 11 -
If you use a larger and therefore mechanically and electrically more rugged gauge
you can remove the jumper J5. The DigitalBooster DB-4 will now supply a
maximum digital current of 4,5 Ampere to the connected track.
6.2. Select the Data Format for WatchDog- and On-/Off switch function:
The jumper J4 has been set ex-factory.
With this setting can be the WatchDog- and On-/Off switch function controlled by
your model railway software respectively via your digital command station by using the
Märklin-Motorola-Data Format.
If you want to use the DCC-Data Format for the WatchDog- and the On-/Off switch
function please remove the jumper J4.
6.3. RailCom
®*
-cutout Creation or Suppression:
The RailCom
®*
-cutout will be created if the jumper J3 has been set. If the Jumper
J3 has been removed there will be no RailCom
®*
-cutout created.
The selection with jumper J3 if the DigitalBooster DB-4 shall create or
suppress a RailCom
®*
-cutout is only possible if the data format for the WatchDog-
and On-/Off switch function has been set to DCC (Jumper J4 removed).
6.4. Short Circuit Report to the Command Station (Short Report):
If the Jumper J1 "Short Report" has been set the DigitalBooster DB-4 will report a
short circuit within the connected track section via the used booster bus to the digital
command station. In this case the digital command station will switch-off all
boosters.
If your model railway software includes a so called Booster-Management this
gadget can prevent that the digital command station will switch-off the complete
layout if a short circuit occurs within a booster section.
The trains will therefore stop only inside the booster section where the short circuit has
been occurred. All other booster sections will remain in function.
To initiate that the DigitalBooster DB-4 shall not report a short circuit to the digital
command station please remove the jumper J1.
