Custom Installation Use; Troubleshooting - Cambridge Audio azur 640C V2.0 User Manual

CUSTOM INSTALLATION (C.I.) USE
The 540C V2.0 and 640C V2.0 feature a Control Bus input/output 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 generated by custom
installation (multi-room) systems or remote IR receiver systems.
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.
In addition the units feature 'direct' IR/Control codes as well as toggle
codes for many of their features to simplify programming custom
installation systems. Special direct On / Off commands can be accessed
on the supplied remote control for teaching into C.I. systems as follows:
1. Press and hold the Standby button. The remote first generates it's
standby (toggle) command. Keep the button held down, after 12
seconds a CD player "On" command will be generated. If the button
is kept held down for a further 12 seconds, a CD player "Off"
command is generated.
