English BiDiBooster
Switching on and off the BiDiBooster with a DCC points
switching command
The BiDiBooster can be switched on and off via a a DCC point switching
command sent to an assigned points address.
Points "straight" à booster on
Points "branch" à booster off
As soon as the BiDiBooster is connected to an interface via the BiDiB-
port, it is impossible to switch the booster on or off via DCC point
switching commands, but only via the PC software.
Inrush-current limiting
The total charging current of buffer capacitors of vehicle decoders
(especially of sound decoders) and other additional external supporting
capacitors can be so high when switching on the layout, that the short-
circuit protection switches off the booster immediately. Thus putting the
layout into operation can be difficult with an active short circuit protection.
The BiDiBooster is able to supply an increased current for a short time
after switching on (to be set to max. 500 ms) and then tolerates a
temporary break down of the voltage. This time is sufficient to charge
buffer capacitors and supporting capacitors.
If after a short time, the current does not decrease and the voltage
does not increase, then the booster ́ s short-circuit switch-off reacts as a
"real" short-circuit has to be assumed.
Further information on inrush-current limiting see RailCommunity
standard RCN 530 (www.railcommunity.de).
Updates
In order to adapt the booster to new developments, you can perform a
software update via BiDiB.
When not having integrated the BiDiBooster in a BiDiB-control, you can
send in the booster for updating.
