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.
	4	IREDs
Refer to	5	IN: BNC input connector for the PPM modulated time-multiplexed signal driving the IREDs (infrared emitting diodes)
fig. 9a.		(7).
	6	OUT: This BNC output connector is connected in parallel to the IN connector allowing you to daisy-chain several
		infrared radiators.

7Power input: Standard IEC power connector for 230 V/50 Hz.

7.1.2Placement

•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.
