Basic Installation Instructions
The Channel Vision Multi-Room Video E Series Modulators are easy
to hook-up. Just connect your video sources to the E Series Modulator
as you would connect them directly to your TV's "video in."
Confirm that the video sources you're going to hook up are sending
good signals. Attach them to the video and audio inputs on the back
of the E Series Modulator. Connect the RF output on the E Series
Modulator to one input of a Channel Vision combiner and your
existing cable/TV/antenna cable to the other. Finally, connect the
output of the combiner to your TV network and plug the E Series
Modulator in to the wall outlet.
Turn your TV on, then press SELECT on the E Series Modulator to
cycle the front display to the A, B, or C input. Then select the channel
you wish to set (the light on the front panel shows the currently
selected input, and the channel display shows the channel to which
that source is currently being sent). Change the channel by holding the
SELECT down for two seconds until the A/B/C light on the front
panel blinks. This puts the E Series Modulator in channel-change
mode.
Press the UP or DOWN buttons on the E Series Modulator to adjust
the channel number as desired. When satisfied, press SELECT again
to exit channel-change mode (the E Series Modulator will
automatically exit channel-change mode after 5 seconds of inactivity).
Repeat for your other two input sources (if applicable). Leave a
channel free between your selected channels to avoid frequency
interference. For example, mapping to channels 32-34-36 is fine, but
32-33-34 is not.
We suggest that you connect a RF distribution amplifier to your cable/
antenna signal (see set up diagram on next page) so you can easily
balance the signal strength of that signal and the E Series Modulator
signal. Extreme differences in signal strength may cause interference.
That's all there is to it. The information on the following pages will
help you configure more sophisticated home "networks" but is not
necessary for basic setups.
System Design Considerations
Sophisticated home "networks" involving many TV sets are feasible
with the E Series Modulator, but care must be taken to design an
optimum TV signal distribution system.
TV sets are designed for signals around 10dBmV. Signals below
0dBmV result in weak, fuzzy, snowy pictures.
Signals above 10dBmV may overdrive older TV sets which don't have
modern automatic gain controls (which can handle signals to
40dBmV). An inline attenuator (pad) can be used to reduce these
signals, and to balance radically different signal strengths at all your
TV's.
Signal strength decreases with coax cable length, and through
connectors, splitters, and combiners, so it's important to determine
how much cable and what in-line devices you'll be using, and adjust
your input signal levels with amplifiers at the front end or in-line on
your network to compensate for the line losses. (The charts on the
back of these instructions will help you calculate likely losses through
coax cable runs and splitters.)
In-line amps are powered through the coax cable and can be used to
achieve modest signal strength gains; more powerful, a/c powered
amps offer more amplification (and usually adjustable gain and tilt
too). Your system should provide 10dBmV to every TV (maximum is
15.5dBmV, per the FCC).
Products to be installed by certified dealers only.
Certification Requirements: Must be professional installing dealer, pass
certification test and familiar with TV and antenna systems. Call 800/840-
0288 for Channel Vision Training Manual and certification test.
Note: This equipment has been tested and found to com-
ply with the limits for a Class B digital device, pursuant to
part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference
in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions,
may cause harmful interference to radio communications.
However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does
cause harmful interference to radio or television recep-
tion, which can be determined by turning the equipment
off and on, the user is encouraged to try and correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and
receiver.
• Connect the equipment into an outlet a circuit different
from that to which the receiver is connected
• Consult the dealer or an experienced radio/TV techni-
cian for help.
