Control Bus - How do I connect control bus between my 851N, 851E and 851W and achieve volume control, power syncing and CAP5 reporting?

Using Control BUS cables:-

Connect 851N (OUT) to 851E (IN)
Connect 851E (OUT) to 851W (IN)
Connect 851W (OUT to 851N (IN)

On 851E:-

Make sure IR RC (first setting in Control menu) is set to Frn+Bck
Make sure C-BUS is set to on
Make sure the first option in 'Devices' menu is set to 'On+Off' - this isn't necessary but will allow the 851E to turn on/off devices over C-BUS
Enable SMx/xxxD in 'Devices' menu under 'Control' - this isn't necessary but will allow the 851E to turn on/off the 851N

On 851N:-

Make sure 'Digital Pre-amp mode' under 'Audio' is set to 'Off'
Make sure 'Network Standby' is selected under 'Standby Mode' in 'Settings'

In Cambridge Connect app:-

Go to 'Settings', enable C-BUS (choose amplifier)

The 851N can now turn off the system via it's front panel control, as can the 851E. The system remote will operate all components. The 851N can control system power and volume from the Cambridge Connect app. The 851W/851E CAP5 reporting is also active.
