TROUBLESHOOTINGCUSTOM INSTALLATION (C.I.) USE
The 840C 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. 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. An RS232 port is also featured which allows the 840C 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 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.
A full code table and RS232 protocol for this product is available on the
