Jubillee works uses MRG https://www.merg.org.uk/ cbus for control of points and accessories and the MERG DCC command station / booster. CBUS allows control modules throughout the layout to communicate over 2 wires minimising connections between base boards. On Jubilee works the DCC is plit into 2 zones so across each baseboard join there are 10 wires.
DCC zone 1 - Dual gauge | 2 | 12V DC 1 - Control boards | 2 |
DCC zone 2 - Narrow gauge | 2 | 12V DC 2 - Servo's and lighting | 2 |
Cbus | 2 |
However between the control pannel and the layout just 4 wires 12vDC 1 and CBUS The DCC command station (MERG kit 91a) feeds a boooster (Merg kit 59) configured for 5 Amp output. Each zone is fed via an district cut out module (Merg kit 57) and there are 2 throttles (Merg kit 92)
With the CBUS if had known when I started what I now understand of its capabilities I would have done things a little differently. Each of the 3 baseboards have a canmio - svo for the servo's, 2 for 1 of the boards, (MERG kit 98) and a canviout (MERG kit 11) providing inputs from the TOTI's and outputs for lighting / smoke units etc.
Train on track indication uses 3 methods (TOTI).
In the engine sheds the MERG PMK7 is used outputting to the canvout. In the transfer shed where there is no motor present Infra red , dual hector units ( MERG kit 72A) are used for presence. I also need an indication of when the stock is pressed against the buffer and micro switches are used for this.
The control Panel uses the canpan (MERG kit 97) in fact 2 of them as t exceeds the 32 LED capacity of a single unit. All switching is momentary leaving the option of multiple panel's either physical or soft.
