Section 7: Infrared Transmission System
7.1 CS 5 IRT 1 and CS 5 IRT 2 Infrared Radiators
7.1.1 General
The CS 5 IRT 1 and CS 5 IRT 2 infrared radiators are capable of transmitting seven interpretation channels to the
CS 5 IRR 7 infrared receivers. The two radiator models are technically identical, except that the CS 5 IRT 2 is larger
than and provides about twice the radiation range of the CS 5 IRT 1.
Each infrared radiator comes complete with a mounting bracket for installation on a wall or ceiling.

1
Green OPERATE LED:
The green OPERATE LED is lit to indicate that signal is being radiated.
2
Yellow OPERATE LED:
The yellow OPERATE LED is lit to indicate that the infrared driver circuitry is in standby mode.
3
MAINS:
This red LED is lit to indicate that power to the radiator is ON.

IREDs
5
IN:
BNC input connector for the PPM modulated time-multiplexed signal driving the IREDs (infrared emitting diodes)
(7).
6
OUT:
This BNC output connector is connected in parallel to the IN connector allowing you to daisy-chain several
infrared radiators.
7
Power input:
Standard IEC power connector for 230 V/50 Hz.
7.1.2 Placement
•
Basically, it is best to place the infrared radiators as close as possible to the area where the receivers will be used
and as high above the floor as practical. Diagram 1 in the Quickstart Manual shows an example of two infrared ra-
diators covering the delegates' tables only.
