PLEASE NOTE:
In some cases, the images used in this manual are of prototype or pre-production units and may vary slightly in appearance
from those actually on sale. However in all cases all of the connections and diagrams are identical and the information given is correct.
The ROCO on-screen App-Based Z21 is sold in two versions, however connections are almost
identical. Roco chose to use an X-bus type RJ12 connector making it similar to LENZ and so it
is good to work with. As a result, if you are a ROCO Z21 user adding Cobalt

Alpha or Cobalt

Cobalt

Box will add lots of power (66% greater power than Z21) PLUS improved
overload protection.
This simple diagram shows how to add an accessory power bus or multiple power districts to ROCO using Alpha
D
Box.
ROCO users can connect via X-bus and so actually have the same sort of versatility with ALPHA products as Lenz, as the
LENZ & ROCO bus are actually very similar. Use the correct adapter leads, and there really is NO limit to what is possible
with ROCO and DCCconcepts Alpha
