IRM-26xxB SERIES
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).
fMeasuring system

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-26xxB 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-26xxB device, it requires the composition of code pattern to reach the demand
as follows:
Minimum burst length & no burst length
TX Recommended Repeat code frame
*Mininum Burst Length > 200μs
*Signal Gap Time > 30ms
*Mininum No Burst Length > 300μs
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.
