Installation Instructions

The Channel Vision Multi-Room Video E Series Modulator makes it easy to map any three
audio/video sources to any unused channels on you television set(s). Watching your security
cameras, laser disk, video tape, or any other video signal becomes as easy as switching channels
with your remote.

Because the E Series Modulator merges these additional inputs into your existing TV signal
"ahead of" your television sets the new channels will be available at every TV hooked up to
your coax cable.

You can even map your stereo system to an unused TV channel to pipe music to any room on
your TV "network!"

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).

Note: Be sure to remove power from outlet before changing DIP
switch settings.

Note: Switch positions are relative to back of modulator.
Note: Black indicates where the switch should be.

Cable (91-135)

Reverse isolation is used to prevent the signal from your E Series from leaking
out to the antenna or cable input. Reverse isolation is accomplished by placing
an amplifier between your antenna or cable company input and the E Series
combiner. This prevents the E Series signal from propagating back up the input
line.

Another way to prevent leakage from your system is to cap all unused coax
cable ports on you network with appropriate terminators.

Bandpass filters stop unwanted frequencies while passing all others along.
They're handy if a channel you want to use for a E Series source is already in
use.

Taps are used to redirect a portion of a signal from the "main" trunk line while
passing the remaining signal strength through. For example, a 12dBmV tap
would pass 29dBmV from a 30dBmV trunk line signal and pass the remaining
18dBmV to a branch line. (Minor signal loss of 1dB would occur in the trunk
line leaving 29dBmV.)

Demodulators are used to demodulate the output of a cable box converter,
making it possible to assign the cable signal to any channel (cable boxes usually
limit your choices to channel three or channel four). Use a demodulator to
"condition" the cable signal before assigning it to a E Series input line.

Adjustments

Stereo Loop: Used to pass stereo to TV on non-stereo modulator. 75Ω position

is normal, 1KΩ position if using stereo loop.

Video Level Adjustment: Adjust the incoming video source base band level.

Use only to increase brightness and balance the channels for consistent
contrast. Spectrum analyzer use is suggested.

Channel Select: Used to select the input source (A, B or C), you wish to

change. Also has a lockout feature to prevent the end user from changing
channels. Press and hold for 2 seconds or until front light blinks to allow
channel up/down to work.

Channel Up/Down: Changes the modulated channel.
DIP Switch Setting: Selection of TV frequency band. UHF = Antenna, Ultra =

Cable.

System Installation Checklist

1. Try for 10dB of signal strength at each television. Use a little more for big
screen TV's. Remember, Uncle Sam doesn't like more than 15.5dB of signal
going into any TV.

2. When laying out your system, there will be approximately 5dB of signal loss
per 100' of RG6.

3. Be sure ALL of your splitters and amplifiers are broadband. Splitters should
be 5MHz to 1GHz, and amps should be 40MHz to 1GHz.

4. Check and make sure that all television are set up for the proper frequency
spectrum (i.e. UHF or cable).

5. Make sure that the channels you want to modulate on have clean "snow".
No lines or interference.

6. Use a low pass filter on every installation to clean up the frequencies the

modulator will be assigned to and keep any potential interference
out of the system. Model 3102, cleans up channel 80 and above.

7. Allow 1 to 2 channel spacing between modulated channels and
"active" channels.

8. Always compensate for insertion loss with splitters and taps.
There will always be a drop in antenna/cable signal strength when
combining a modulator to an existing system (because of insertion
loss with the combiner).

9. When combining an existing signal with a modulated signal, make
sure to have equal signal strength at the point of the combiner so
one signal does not degrade the other and cause beat frequencies.

10. When possible, use the lowest frequencies available for the
modulated channels. Lower channels (frequencies) have lower
signal loss on the cable runs.

11. When in doubt, run the signal a little high to the television and use
an attenuator to lower the signal strength going into the TV.
Attenuators may be combined (i.e. two -3dB attenuators. will
equal -6dB).

12. Make sure to use a well shielded coax of either RG6, RG6 Quad
or RG11 for long feeder drops.

13. Use RG59U Coax for composite/baseband video signals only.

14. Combine the modulator into the video distribution system as far
"up-stream" as possible.

15. If the system needs to be amplified use the amplifier as far "up­stream" as possible.

Trouble Shooting

Trouble shooting any system can make or break the entire installation.

Here are the most common problems and solutions. After trying
these solutions, call 800/840-0288 for 24 hour technical
assistance. Calls before 8am and after 5pm pacific standard time
will be returned by the technician on call.

Stops Modulating : No Modulation
Modulator requires proper ventilation for long life reliability and

continued operation. Unplug unit, let it cool down, install in well
ventilated area to continue operation.

Snowy Picture : No Modulation

This is a problem of the TV and the modulator not "talking" to each
other.

1. Verify the modulator is set up for the proper TV channel band. If

cable TV or antenna? If the unit uses dip switches to set the
channel band, was the unit powered down during or after the
switches were reset to the proper band? If the unit uses a jumper
check for proper placement.

2. Verify the TV is set up on the proper TV channel band. Use

"Air" for UHF channels or Cable for Ultraband channels . The
TV will have an on screen set-up menu or a switch for this
function. Also make sure the modulated channel isn't blocked out
by auto-programming. To check for the TV being set to the
wrong band, go to the equivalent channel on the other band (i.e.
to check 65 cable try 14 UHF). Add 51 channels for antenna
connection to cable channels.

3. Check TV manual to make sure TV works on channel above 65.

4. Check all connections for a good connection.

5. Check splitters and amplifiers for 1GHz rating.

6. Try another TV, bypass all components and go directly into TV.

Black Picture : No Modulation
In this case, the TV and the modulator are "talking" to each other. The
video signal is not being passed through the system.

1. Verify good connections to the modulator from the video source.

i.e. VCR.

2. Check video source (VCR, Sat Receiver etc.) by running the

outputs directly into the video inputs on the TV. Verify video

source is working.

3. Check for power at video source.

4. Disconnect modulator from system:
A) Picture goes to snow, problem is between video source and

inputs on the modulator.

B) Picture stays black, hook up the modulator

directly to a TV eliminating all the components of the system and
check the picture.

Grainy Local Channels : Good Modulated Picture

1. Disconnect the modulator from the system and connect the local
channel feed directly to the distribution system and check TV picture
quality.
A) If the picture quality is good the insertion loss of the

combiner for the modulator is degrading the local channel
signal. Use a CVT-15PIA to compensate for the insertion loss.

B) The other alternative is to use a 6dB tap as the combiner, put

the local channel feed on the pass through port for a minimal
loss of signal connect the modulator to the tap off port.

C) If the picture is still bad, check for a bad connection where

leakage may occur or if the shielding braid is touching the
center conductor.

2. Install model CVT-15PIA amplifier on the incoming cable
before the combiner. See basic schematic.

Grainy Modulated Channel : Good Picture on the Cable Channels

1. Disconnect cable channels from the system and check the

modulated channels.

A) If the modulated channels are good, use a low pass filter to

"clean-up" the incoming frequencies to be modulated.

B) If the modulated channel does not improve after

disconnecting the local channels, evaluate signal loss of
modulator through the splitters and cable length of the
system. Amplify after the combiner if needed.

C) Also check the connections between modulator and the

combiner for leakage or the cable braid is touching the center
conductor.

2. Check output strength with field strength meter.

3. Connect modulator directly to TV and check picture quality.

4. Check bandwidth of all splitters and amplifiers for 1GHz

capability.

5. Place TV cable setting on standard, NOT

TV Won't Tune High Enough to get Modulated Channel

1. Use an external tuner i.e. VCR or a Cable Box converter tuner

(Channel Vision Model #1172) to allow the TV to view a
modulated channel on channel through the external tuner..

2. If the modulated channel is beyond the capabilities for that TV,

the TV will not work with the system.

Cable Company Box Won't Pass a Modulated Signal

1. Connect modulator directly to TV and verify the modulator is

sending a signal the TV can receive.

2. Use model 3101 Cable Box Combiner Kit to route the modulated

signal around the cable box. See schematic page..

Cable Company Uses All Available Channels

1. Use a low pass filter (3102) to block out channels 80 and above

for clean modulation (won't effect channels 95-99).

2. Call for pricing on a custom filter to block out a specific channel

or multiple channels.

Modulated Picture is Too Bright or Washed Out

1. Slide impedance switch to 75Ω position.

2. If modulator is a E Series set top style, adjust video level

adjustment potentiometer on the bottom of the chassis.

3. If using a camera, check positioning of the lens to be sure it's not

HRC or IRC.

aimed at the sun or a reflection.

4. Adjust camera lens - see lens manual.

Modulated Picture is Too Dark

1. If baseband video is being split with a Stereo Loop Kit or loop
through quad, set impedance matching switch (termination
switch) to 1ΚΩ.

2. If modulator is a set top style, adjust video level adjustment
potentiometer on the bottom of the chassis.

3. If the video source is not being split, check input source

directly into a TV.

4. Adjust the video level adjust pot on the chassis of the set top
units to the proper brightness.

5. Check all connectors for 75Ω.

Noise on the Audio

1. Insert grounding block in line and ground coax cable before it
enters the TV.

2. Use professional grade audio/video interconnect between the
components and the modulator.

Audio is Too Low

Use a Y-Connector to combine the left and right audio before entering

the modulator.

Herringbone in Picture on Modulated Channel
Disconnect modulator from local channels an check modulated

channel.

A) If there is programming move the modulated channel.
B) If the picture is snowy, use a #3102-78 low pass filter to block

noise or data coming in from cable company.

C) Separate modulated channels by two channels.

Horizontal Bars Rolling Through TV Picture

1. Check for a component of the system to introduce
DC power into the system. Disconnect that
component and check TV. If the hum bars stop, use a DC blocker
down stream from that component to block the power from
getting to the TVs.

2. If the rolling is only on the modulated channels,
check for impedance mismatch by adjusting the
video level adjustment pot.

Vertical Bars Rolling Through TV Picture
Check for AC power getting on the line. Use a ground breaker in line.

Black and White Lines on one Local Channel

Move modulated channel up to a new channel. If

problem persists and all of the inputs of a multiple
input modulator are not being used, check default
channels on modulator to see if default channel is
set to the same channel that the problem channel
is set to.

Flashing at the Top or Middle of TV Picture

1. If flashing is on modulated channels, turn up
attenuator/down gain of modulator.

2. If flashing is on local channels turn down gain or
attenuate output of amplifier.

3. Install filter #3102-80 to clean up channels.

Picture is Tearing
Possible impedance problem. Check that impedance switch is set to

75Ω.

Ghosts on the Picture

1. Terminate all unused ports with 75Ω terminator
model 2101.

O u c h!!!

2. Check for low quality combiner in system.
Replace with high isolation combiner, HS model
combiner.

3. Check the type of coax used in system. Inadequate shielding in
coax will cause ghosting. Pull new coax (RG6 quad).

Low Channel Pictures are Good, High Channel

Picture is Grainy

1. Place a tilt compensator in line after the amplifier
and increase amplifier gain until the higher
channels look good.

2. Check frequency specifications on all splitters and amplifiers in
system. Replace any that are not broadband 5MHz to 1GHz.

Low Channels are Wavy Vertical Lines, High Channels are Good

1. Unplug the modulator

a) Channels look good : problem is beat frequencies or

unbalanced cable vs. modulator.

1. Decrease modulator power by adjusting attenuator (red

knob on back) or use external attenuators before it is
combined with the cable TV signal.

2. Use a 9 or 12dBmV tap in reverse instead of the supplied

combiner.

3. Install a 5 or 10dBmV tilt compensator to reduce low

channel power.

4. Amplify cable TV before you combine modulated signal to

balance.

b) Low Channels are still bad : bad component in system.

1. Check signal at source without splitters, amplifiers etc. in

the system.

2. Read system installation checklist.

3. Trace picture from beginning to end. Use process of

elimination.
c) Picture still has wavy lines at the source
Call for cable company service. They have a bad component in

their system Garbage in equals garbage out.

TVs not Receiving all Channels Being Distributed

1. Check coax, if RG59 replace with RG6.

2. Check all splitters and amplifiers for broadband specifications.

3. Check TV specifications for available channels.
