DigitalBooster DB-4 – Manual
- 12 -
With the output “Feedback“ of the DigitalBoosters DB-4 is it possible to inform your
model railway software if the tracks receive presently digital current from the DB-4 or
if the tracks are switched voltage-free caused by a short-circuit.
6.5. Automatic Switch-On (Auto Go):
With the jumper J2 “Auto Go” is it possible to adjust the DigitalBooster DB-4 that the
unit perform a continuous check every 5 seconds if a short-circuit is still present.
The DigitalBooster DB-4 will supply current to the connected track section
automatically if the short-circuit has been eliminated. The jumper J2 has be set for
this function.
The automatic switch-on function is not activated if the jumper J2 has been
removed.
For activating the automatic switch-on function “Auto Go” has the jumper J1
“Short Report” to be removed and therefore is the DigitalBooster DB-4 not reporting
recognized short circuits to the digital command station.
7. Addresses for WatchDog- and On-/Off switch function:
The WatchDog- and the On-/Off switch function of the DigitalBooster DB-4 will be
controlled via accessory addresses (turnout addresses) which are used as well for
the switching of turnouts or signals.
Accessory addresses are combined at groups of four. The addresses 1 to 4 are
forming the first group the addresses 5 to 8 the second group etc. The highest
valid four-fold address group for the programming of the DigitalBooster DB-4 is for
Märklin-Motorola data format the group 313 to 316 and for the DCC-data format the
group 1021 to 1024.
From our Web-Site you can download at the section ”Downloads” the file “Four-
Fold-Address Blocks” for listing all valid four-fold address groups.
The WatchDog- and the On-/Off switch-function can be assigned to an own or as
well to a common four-fold address group. Separated address sections for the
WatchDog- and for the On-/Off switch-function are recommended if you use several
DigitalBooster DB-4. Then is it possible to release the WatchDog-Function of all
boosters via one common address.
For the On-/Off switch function is it possible to assign for this case for each
DigitalBooster DB-4 an individual address over an own four-fold address group.
The address for the WatchDog-Function is always the first address (basic address)
of a four-fold group. The address for the On-/Off switch-function is always the third
address (basic address + 2) of the programmed four-fold group.
