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.
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. 75 Ω position is normal, 1K Ω 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 HRC or IRC.
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 75 Ω 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
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 1 ΚΩ.
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 75 Ω.
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
75 Ω.
Ghosts on the Picture
1. Terminate all unused ports with 75 Ω terminator model 2101.
2. Check for low quality combiner in system.
Replace with high isolation combiner, HS model
O u c h!!!
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.
