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,Δλ=50nm. Also, photodiode is used of PD438B(Vr=5V).

IRM-36xxD SERIES

The Notice of Application:

Transmission o remote control signal consist of four parts: Encode Part, IR Transmitter Source,

IRM device, Decode Part

1. When IRM-36xxD 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-36xxD device, Minimum Burst Length Tburst (number of pulses per burst) : 10

cycles

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

5. IRM-36xxD can use More Tx Repeat Continuous Codes, but against disturbance slightly weak

Repeat Continuous Code Mean:

*Minimum Data Pause Time : < 1msec

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

of signal.
