Channel Vision modulators allow you to create your own TV
channel for video devices so they can be easily distributed
through your home. Common uses include CCTV cameras,
DVD players, and satellite receivers.
The IR-4000 is the heart of the coax IR repeating system. It
allows power to be inserted on the coax and it provides an IR
emitter port to output the IR control signals. An IR engine is
built into the E2200IR, E3200IR, and E4200IR modulators.
The IR-4101 is an IR over coax receiver to be connected into
the system on each output where IR control is needed.
IR receivers detect the IR signal from your remote control and
convert them into pulses that can travel over a wire, in this
case coax cable.

Frequently Asked Questions
Why do I need a 5-42MHz return path?
What are DC passing splitters?
What is IR repeating?
How should I connect my cable modem?
Unlike conventional cable TV systems, new digital cable
systems require the cable box to have two-way
communication with the cable company. This means that
signals need to travel from the cable company to your
home and then from your home back to the cable
company. The frequency range between 5MHz and
42MHz has been reserved for the return communication
signals. Traditional RF amplifiers that were designed
before the advent of digital cable did not accommodate
this return communication and would not allow digital
cable boxes to function properly.
Some products utilize your existing coax cable to distribute
IR control signals throughout your home. This technology
requires a Direct Current (DC) voltage to be transmitted
over the coax wire. Conventional RF splitters will cause
this voltage to short out and disable the IR repeating
system. Most Channel Vision Splitters are DC passing and
will support this kind of IR repeating technology.
IR repeating systems allow you to use a handheld infra-
red remote to control devices that are located in another
room of your home. Channel Vision offers a variety of IR
repeating solutions, please visit www.channelvision.com
for a complete list.
Although the 5-42MHz return path provided by the
amplifier will allow the modem to communicate with the
cable company network, connecting your modem directly
to the amplified splitter is not recommended. Doing so
can allow the modem signal to be corrupted by noise
generated by TV sets that are connected to the other
outputs. See the diagram on the following page for the
recommended setup.
