Test Method：

The specified electro-optical characteristics is satisfied under the following Conditions at the controllable distance.

cMeasurement place

A place that is nothing of extreme light reflected in the room. dExternal light

Project the light of ordinary white fluorescent lamps which are not high Frequency lamps and must be less then 10 Lux at the module surface. (Ee≦10Lux)

eStandard transmitter

A transmitter whose output is so adjusted as to Vo=400mVp-p and the output Wave form shown in Fig.-1.According to the measurement method shown in Fig.-2 the standard transmitter is specified.

However , the infrared photodiode to be used for the transmitter should be λp=940nm,∆λ=50nm. Also, photodiode is used of PD438B(Vr=5V). (Standard light / Light source temperature 2856°K). fMeasuring system

IRM-3638T The Notice of Application:

Transmission of remote control signal consist of four parts: Encode Part, IR Transmitter Source, IRM device, Decode Part

1. When IRM-3638T code select frequency, it need to well understand the center system of encode part.

2. Strong or weak light of IR Transmitter can affect distance of transmission.

3. When using IRM-3638T device, it requires the composition of code pattern to reach the demand as follows:

Minimum tburst

( number of pulses per burst)

10 pulses

Minimum tburst_gap ( number of pulses between two burst)

14 pulses

Minimum tpause

25 msec

4. It needs to ensure the translation range of decode part if it is applied to the pulse-width range.

If the above items hardly assure of its application, it’ll cause NG(no good) message from the edge of signal.
