The jacks in the control connection area of the rear panel can link the C 1 to a wide variety of
devices beyond those that deliver or receive audio and video signals.
RS-232 Control
This 9-pin, full-duplex serial port has several potential uses.
For one thing, it allows the C 1 to communicate bidirectionally with widely available, software-based
home automation and control systems such as AMX or Crestron. When the C 1 is connected to one
of these systems, it can be controlled and its status monitored from keypads and handheld or table-
top touch-screen remotes throughout your house. The capabilities of such connections, and the pro-
gramming and interfacing needed will depend on the automation system you select; consult your
Parasound Dealer or Custom Installer for more information regarding interfacing an external control
system to your C 1.
The RS-232 port’s second use is for programming. If you link the RS-232 port to a serial port on a
PC, you can use free Windows software to program every aspect of the C 1 Controller’s operation,
and make backup copies of program settings you have made via the C 1 front panel or with its
Master remote. (The program, which requires Windows 95 or higher, can be downloaded from
www.parasound.com/halo, and a standard RS-232 serial cable can be purchased at any dealer
who sells PCs or computer accessories.)
Further, the RS-232 port can be used to update the C 1 Controller’s operating software should future
developments (such as new types of surround recording) make it necessary, or simply to incorporate
ongoing Parasound upgrades. We’ll post news about product developments on our Web site.
IR Inputs
These two jacks accept remote-control signals relayed, or “repeated” from remote IR receivers, or
sensors. Repeater systems extend the range of your remote-control handset, permitting it to con-
trol the C 1 when it is installed in a cabinet with closed doors. Each of the two IR input jacks on the
C 1 is dedicated to control of a single zone.
The “Zone” IR input is used to operate the C 1 from the second (remote) zone, and commands
received through this jack affect only remote-zone operation.
The “Main” IR input affects only the local zone, enabling you to operate the C 1 if it’s mounted out
of sight in a cabinet or equipment closet, or from other rooms within the local zone. (Note: Position
the C 1 and any remote infrared sensors in the main room so that the beam from a remote-control
handset cannot reach both at once; otherwise, the C 1 may not respond correctly to the remote’s
commands. When positioning the C 1 and sensor, remember that infrared can be reflected, just as
other light wavelengths are.)
