Figure 3-5: Video RZone Card. The RZones are counted from right to left; hence slot 11 is reserved
for RZone 2, and slot 12 is reserved for RZone 1.
Each card includes an S-video output, a composite video output on
an RCA connector, and a dedicated infrared (IR) input that is
specific to the particular zone.
Connect either (or both) of the video outputs to your intended
remote zone display device or video recorder, according to your
system design.These video outputs can easily drive extremely long
lengths of high quality 75Ω cable; however, as with any video
signal, long cable runs really require excellent quality cable to avoid
signal deterioration. Please consult with your dealer on the best
choice of video cable to suit your system design.
From the front panel, you can select the zone you wish to change
using the zone knob, and then route any defined input to both the
video outputs (S-video and composite) associated with the selected
RZone.
If you need to control a particular zone from a remote location,
simply use IR “repeaters” to direct appropriate infrared commands
to the IR input on that RZone card, in the video processor. Any
commands received at that IR input will be interpreted as being
intended for that particular RZone.
Keep track of how these outputs are used, either by keeping a
simple list or by making a note on the Hookup Chart at the end of
this manual.
See “Using the RZones” on page 6-1 for more information on
configuring your RZones.

IEC Power Input
Please make a note of your Nº40 video processor serial number. You
will need this information should you ever require service on your
Nº40.
Figure 3-6: Label & Power Plug. The AC power switch on the front panel disconnects the Nº40
video processor from the wall outlet’s AC power. Check to ensure
that the power switches on both the processors are disengaged
(protruding from the front panel), then plug the supplied three-
prong power cord into the AC mains receptacles before plugging
the power cords into the wall. (If a longer AC power cord is required
for your application, be sure to use a three-conductor power cord
which conforms to IEC standards.)
Also connect the Nº40 communications cable between the two
processors as indicated in “Nº40 Communications Port” on page 3-
9. This cable allows the video and audio halves of the Nº40 to work
as one.
Once the connections are all firmly made, switch on power at the
front panels of both components. After approximately a 30-second
