The BlackBox is not DCC so does not address any locomotive but operates like a DCC throttle...!
It can be used in analog DC with any NMRA compatible dual mode decoder, eg: BLI/QSI, Atlas, Life-Like, Athearn, ESU Loksound, MTH, MRC, Precision Craft, etc.
Instead of having to buy a control box from every company to operate only their locomotive, this can operate them all. so all you need is just one box.
It operates all the sound functions that the particular loco has inside of it, but can not operate functions that are not there; for instance, it will access up to F28 on the MTH K-4, but a normal BLI/QSI loco may only have up to F12, so there is no F28 to access in that loco.
It is a very simple 4-wire hook-up - two wires to your DC powerpack\'s variable output, and two wires to the track.
If you use non-decoder equipped locos the BlackBox must be removed from the power pack to run them or be equipped with a NMRA compatible DCC decoder.
The BlackBox can be used in a layout with block control, [cab A/cab B], as one of the cabs so you can run sound loco\'s on one cab, and normal DCC locos on the other.
