Expanding the 3308:

CATV/Ant

Model 3308

Up to 64 TV outlets

You may connect up to 8 more 3308s to the outputs of a ‘master’ 3308, for a total of 64 TV outlets. The longest recommended coax run is 150 feet (includes coax from master to secondary unit and from secondary unit to TV).

Mounting the 3308

The model 3308 should be mounted in a location that is safe and dry. The model 3308 is small enough to be mounted inside a stud wall. Alternatively, the 3308 may be mounted inside a ChannelPlus Integrated Home Network enclosure.

All 3308s must be powered individually.

Each 3308 can have its’ own ‘zoned’ IR control and local modulators. (Modulators connected to a secondary 3308 will be viewable only on those 8 TVs. IR control signals will be confined to only that 3308.)

Circuit Breaker

The model 2010 and 3308 have built-in circuit breakers. If any of these LEDs are not lit, reset the circuit breaker by disconnecting and reconnecting the power supply. If the system does not reset, look for an installation error.

Things to watch for:

Herringbone interference on modulator channel (diagonal lines) ...

You may have chosen a channel number that is not completely vacant. Distant UHF stations may not be watchable, but will cause interference if you try to try to create a new channel at the same frequency. Also, cable companies often have extra signals where there should be none. Try moving the modulator channel to another number. You may have to add a low pass filter to remove cable company noise. If a filter does not work, try adding a DC-block to remove common mode interference.

Herringbone interference on many channels, including modulator channels (disappears when you remove the CATV/Ant feed) … The RF amplifier can be

overloaded by abnormally strong signals. Often, you can cure the problem with a simple attenuator. Use a variable attenuator and try to find a signal level where the interference just disappears. Sometimes, the problem is one station that is far stronger than the rest. In this case, attenuating all of the signals with a simple attenuator will cause the desired stations to be weak (snowy). You must reduce the strength of only the offending station. A common FM trap will help if the problem is a nearby FM tower. If the problem is a nearby TV station, often the

Infrared Remote Control Problems … The most common cause of IR problems are:

IR emitter not located directly above sensor on the video device. Reposition the IR emitter

TV is radiating electrical noise. Reposition IR target.

IR target is ‘seeing’ optical noise, such as a solid state flourescent lamp. Reposition IR target.

TARGET

We recommend using only RG-6 coax when wiring a house. Why? Although good RG-59 has only slightly more loss than RG-6, it is harder to find good RG-59. RG-6 is a little more expensive and a little harder to run (because it is thicker). But you will avoid surprises if you stick to RG-6.
