Channel Plus H838BID specifications OpenHousetm modules attach from the top, IR repeating system

ChannelPlus Video Hubs

The H838 video hubs distribute antenna or cable signals to up to eight

televisions. The hubs provide two video modulator inputs to create new channels and have built-in IR engines to

support 5V IR targets.

Two models are available.

The H838HHR has the isolation required by the FCC for any system that has modulators and an antenna.

The H838BID has a 5-42MHz reverse channel to support bidirectional cable systems (cable modems, pay-per-view and interactive cable).

You may connect as many as 8 more H838s to the outputs of a master H838 for a total of 64 television outlets. The longest recommended coax run should not exceed 150’. (That is a total of the coax from master to slave and from slave to TV.)

Typical remote control

To control your video devices, add a modulator with IR repeating, an IR target and an IR emitter. Point a remote control at the target in the bedroom and IR pulses are repeated by the emitter, controlling the DVD player in the den.

Any or all of the television ports may have targets connected.

Expanding the modulator inputs

Add a model H881 active combiner and a single modulator input becomes eight.

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 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 the cable company noise. If the 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/antenna 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 is far stronger than the rest. In this case, attenuating all of the signals with a simple attenuator may cause the desired stations to be weak (snowy). You must reduce the strength of the only 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 station management can provide suitable filters.

FCC Requirements:

THIS PRODUCT COMPLIES WITH FCC REQUIREMENTS.

A SYSTEM USING THIS DEVICE WILL COMPLY WITH FCC REQUIREMENTS. USE ONLY VIDEO MODULATORS THAT COMPLY WITH PART 15

OF THE FCC RULES AND HAVE 25dBmV MAX OUTPUT LEVELS. FAILURE TO DO SO MAY VOID THE USER’S AUTHORITY TO OPERATE THIS EQUIPMENT. THE H838HHR IS SUITABLE FOR USE WITH AN ANTENNA OR WITH

CATV SYSTEMS.

THE H838BID IS SUITABLE FOR USE WITH CATV SYSTEMS.
