Custom Installation (C.i.) Use - Cambridge Audio azur 851D User Manual

Custom installation (C.I.) use

The 851D features 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. 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.
An RS232C port is also featured which allows the 851D to be controlled
by C.I. systems.
In addition the units feature 'direct' IR/Control codes as well as toggle
codes for some of their features to simplify programming custom
installation systems. Special direct On/Off and Mute commands can be
accessed on the supplied remote control for teaching into C.I. systems
as follows:
1. Press and hold the Standby/On button. The remote first generates
it's standby (toggle) command. Keep the button held down, after 12
seconds an amplifier "On" command will be generated. If the button
is kept held down for a further 12 seconds, an amplifier player "Off"
command is generated.
2. Press and hold the Mute button. The remote first generates it's mute
(toggle) command. Keep the button held down, after 12 seconds a
"Mute on" command will be generated. If the button is kept held down
for a further 12 seconds, a "Mute off" command is generated.
