Create elegant control panels with only ONE cable needed for layout connection!
Of course, many layouts will need multiple Cobalt DAlpha or Cobalt DCentral, all together or
distributed around the layout, in order to control MANY Accessories. This is a simple process....
You can choose how its done. Several Units sharing one Cab number, all connected together in one place and joined with the link
cable supplied, or several units distributed around the layout, each with its own “Cab” number and unique addresses..

Linking several units.
This is done using the cable
supplied with each Alpha Unit.
Use 1, 2 or more Cobalt DCentral or Cobalt DCentral - it’s up to you!
This diagram uses the NCE PowerCab which can connect directly as it uses the
conventional RS485 connection structures. ALL other brands can also connect
in a similar way with the help of adapter leads. (See individual brand diagrams)
You can choose how its done. You can also extend the control bus of your system
by adding layout connection panels for the command bus at places marked (A) here.

Please do NOT make connections without using adapters - see P26~27.
Alpha uses RS485 type wiring as follows (if you are facing the socket):
For LHS input RJ12 (main command bus connection)
(track data ~ -12v ~ data ~ data ~ + 12v ~ track bus)
For Central input RJ12 or Interconnection RJ12 (Cab bus connection)
(No input ~ -12v ~ data ~ data ~ + 12v ~ No input)
The RHS input is ONLY ever used for Cobalt Alpha Units.
