8 RS-232 Control Port
This DB-9 connector has two purposes:
• downloading new operating software into your preamplifier (should new
features ever be added, for example)
• external control of your preamplifier by control systems such as i-
Command ™ , AMX
For more information, please contact your dealer and ask about home automation
systems.
9 Classé CAN Bus Control Ports
These RJ-45 connectors are reserved for future control and communication
applications using Classé Audio's implementation of the Controller Area Network
(CAN) Bus specification.
10 IR Input and Output
Your Classé preamplifier includes two 1/8th-inch mini mono-jacks in order
to support the infrared (IR) remote controls that are ubiquitous today. Infrared
commands exist (for example) for toggling the preamplifier between operate and
standby, in addition to discrete command codes for either operate or standby.
These codes may be used in "macros" for sophisticated remote control systems,
facilitating the control of the preamplifier in the larger context of a complete
system.
The list of commands available is quite extensive, enabling even complex macros
(chains of commands strung together) to operate flawlessly. If this capability is of
interest to you, we strongly recommend discussing it with your authorized Classé
dealer.
Note that IR Input and Output is a bit of a misnomer: the input and output
of these plugs is electrical in nature, not infrared. They are used with standard
IR receivers, distribution amplifiers, and emitters (available from your dealer)
to translate the remote's IR signal to an electrical signal and vice versa. The big
advantages here include being able to easily route the signals anywhere they might
need to go and the reliability of a solid electrical connection.
Since an IR distribution system such as your dealer may design for you usually
must control many products, your preamplifier includes both an IR input (for the
control of this product) and an IR output (so as to pass along the same signal to
the next product). This allows you to "daisy chain" your control wires from one
product to the next.
The preamplifier is designed to respond to IR commands of 5 Volts DC, with the
tip of the mini-plug defined to be positive relative to the shank of the plug.
