Product Description
Capitalizing on the competitive features and pricing of its successful family of CTARM modulators, the CTARM-IR allows the use of infrared hand held remotes to control any device in the house from anywhere in less than one tenth of a second. This permits the user to view programming content at a site separate from the location containing the modulated video source while retaining the ability to change channels on the video source from the remote location with virtually no delay. For example, a DVD player located in the family room can be modulated on channel 105 so it can be viewed on a bedroom TV. The DVD remote can be used in the bedroom to control the DVD player. The remote control signal is transmitted through the same coaxial cable that carriers the RF signal to the bedroom TV.
The CTARM-IR series includes the CTARM-1LTIR, CTARM-2LTIR, and CTARM-4IR that are respectively single, dual, and quad input modulators. In addition, with loop through ports the CTARM-1LTIR and CTARM-2LTIR preserve stereo audio and video signals at the source for those customers having home theater systems. Each unit is housed in a low profile case with channel output selection buttons and LED channel display. Non-volatile memory is included to remember channel assignments in event of power failure.
Further, consumers can add up to seven TVs at any time with the use of Cabletronix’s optional CTIRE-8 eight output infrared engine.
How Does It Work?
The CTARM-IR products use a target to receive the infrared (IR) signals from a hand held IR remote control and convert the IR signals to a control signal that will pass through coaxial cable. The control signal is routed into a TV/IR diplexer where it is mixed with the television signal. The control signal is carried over the coaxial cable backward to the device the hand held remote operates. At the other end of the coaxial cable the signals are separated at the RF/IR modulator or IR Engine, and the control signals are sent to an infrared repeater placed near the IR component to be controlled. The IR repeater will emit an IR control signal identical to the one that was received from the hand held remote control aimed at the originating target. This IR signal will then operate the desired device. This whole process occurs in less than one-tenth of a second.
