Smart Booster v 1.65B
The SB5 Smart Booster adds expanded and updated features to a Power Cab
DCC system. The first and most noticeable feature is additional power (5 Amps)
to run trains and accessories.
Your PowerCab used with the SB5 can now be unplugged and used in true
walk around fashion. It no longer needs to remain connected for the system to
work.
Up to 6 cabs can be used with the SB5 (Cab address range 2 through 7).
Equipped Cabs have up to six recalls each when used with the SB5.
Additional 5 Amp boosters (DB5) may be added to the SB5 for even more
power handling on larger layouts.
This manual covers only the addition and installation of the SB5 to a Power Cab
system. For operation consult your Power Cab manual.
The SB5 does NOT have a programming track output. The basic Power Cab
provides this capability.
