4.5 IR (Infrared) SIGNAL connection
Usually, IR transmission is used to control an appliance (DVD player, Satellite,
etc.) located close to the transmitting unit, from the receiving station using a
remote control.
However, the circuitry used in the dual TPA110 IRT/ IRR also permits a reverse
path. Transmission may therefore be bi-directional but not simultaneous.
If two users transmit an IR signal concurrently from the receiving and
transmitting station, a line conflict occurs and the transmissions will fail.
4.5.1 IR RECEIVER connection
The IR receiver is an electronic device able to transform IR light impulses emitted
by a remote control into an electrical signal.
The IR receiver must be positioned so that can be easily reached by the IR beam
emitted by the remote control. It is usually installed on a wall at medium-high
height. When installing the IR receiver, always comply with the manufacturer's
instructions regarding:
-Sensitivity
-Exposure to environmental and sunlight
-Settings and calibration
When selecting the IR receiver, the user must pay particular attention to the
operating frequency of the remote control whose signal is remotized.
Most remote controls operate at low frequencies but some manufacturers (Bang &
Olufsen, Kenwood, Pioneer) use remote controls with carrier frequencies of up to
1,125MHz.
that is compatible with the frequency of the remote control.
