Custom installation C.I. use | Cambridge Audio 540D V2 specification

Custom installation (C.I.) use

The 540D V2 features a Control Bus input/output IR Emitter		Control Bus
that allow un-modulated remote control
commands (positive logic, TTL level) to be received
electrically by the unit and looped to another unit
if desired. These control commands are typically	In	In	Out
generated by custom installation (multi-room)	In	In	Out

systems or remote IR receiver systems. The Control Bus sockets are colour-coded orange.

An IR Emitter Input is also provided that allows modulated IR remote control commands to be received electrically by the unit. Commands on this input operate the unit only and are not looped out demodulated on the Control Bus Output. This feature is useful for multi-room systems (such as the Cambridge Audio Incognito multi-room system) which feature routed I.R. emitter outputs. Instead of using window emitters stuck over the CD players front panel IR receiver, a mono 3.5mm mini- jack to 3.5mm mini-jack lead can be used for a more reliable electrical connection.

The 540D V2 also features a ‘direct’ IR/Control code for On/Off that can be accessed on the supplied remote control for teaching into C.I. systems as follows:

Press and hold the Standby button. The remote first generates it's standby (toggle) command. Keep the button held down, after 12 seconds a DVD player “On” command will be generated. If the button is kept held down for a further 12 seconds, a DVD player “Off” command is generated.
