TUNE A CABLE BOX FROM ANOTHER ROOM

INSTALLING THE RF TRANSMITTER
IR to RF to IR TRANSCEIVER

Hi all,


There have been some questions about second, third and even fourth TV sets and the fact that our contract, initially, only provides one Set Top Converter. This post will present a little trick for helping to overcome this issue.

The little black hemispherical object pictured above is an RF to IR Transceiver.

OK, what is this all about; your remote control that will operate your new Cable box emits an IR signal when talking to the box. IR simply means an Infra Red signal. This IR signal operates Line of Sight (LoS) only.

RF indicates a Radio Frequency signal which at the right frequency operates through walls and windows.

So, if you split the signal coming from the Cable box and run one Coaxial wire to, say, the living room TV and one to the TV in, say, the bedroom, you now merely need a kit which converts the IR signal normally emitted by the remote control to an RF signal.

This RF signal will be picked up by the Transceiver pictured above. This little device will be placed directly in front of the Cable box and when the device converts the received RF signal back to IR, your cable box will respond by changing the channel.

Below is a reference to such a kit; there are others, but this one will give you the idea. Other brands may be available locally at Radio Shack or similar store.

Before you go out and buy this, or similar kit, let me run this idea past Comcast Tech. for compatibility with their equipment.
