The remote control extender POWER-LINK allows to command any audio/video equipment that uses IR technology of remote control (satellite receivers, VCRs, DVDs, stereos etc.) from other rooms. Such a possibility is especially useful within apartment/house installations, where one DVB receiver with conditional access should serve several TV outlets in separate places. The requirement for using that device is properly made antenna installation, which can be based both on splitter or tap principle. The extension equipment is supplied with its own dedicated 12V power supplies that are part of the set.

View of the device (re-emitter and receiver).

Power supplies are part of the set.

The equipment consists of IR receiver that converts the control IR commands to 11 MHz HF signal and lets it into antenna installation, and IR sender ("reemitter"), which changes back the signal to its IR original form. There are also available additional IR receivers alone.

In order to properly position the IR emitter it is needed to connect both modules and choose the place for the sender (A) experimentally (Fig. 1).

The IR controllers of the equipment that is to be commanded should be put into a box , making impossible direct operation (the equipment does not "see" the controllers - it ought to be tested for sure). The sensor of the receiver (B) has to be put into the box, too. Then the IR reemitter ought to be linked with antenna installation. The same is made with IR receiver. It should be connected to an antenna outlet, and the cable leading signal to TV set - to the IR receiver's socket. (Fig. 2).

The sensor of receiver (B) should be put close to TV set, in a way allowing direct IR transmission. In the case of bigger installations or high attenuation taps being used it may be needed to adjust the HF output signal, which can delicately be made with a small size screwdriver.

Notice:

a - Make sure that sender (emitter) A and sensor (receiver) B are properly placed and fixed, and direct IR transmission is always possible.

b - When a number of POWER-LINK items are used, check whether one of cases shown in 4a...4c figures does not upset proper operation.

c - When the antenna installation between the rooms employs an amplifier, the extender will be useless.
