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).

IRM-27xxA 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-27xxA 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-27xxA device, it requires the composition of code pattern to reach the demand
as follows:
Minimum Burst Length tburst (number of pulses per burst) : 10 cycles
Minimum data pause time:
Remocon TX code with Repeat key
Remocon Tx code with Full frame Repeat
Remocon TX repeat Code with minimum
burst length
Tactual , data = Tdata − ∑ (TBn − 150 µs )
n
Tactual , gap = Tgap − ∑ (TBn − 150 µs )
Tgap ≥ 2.0 ∗ (Tr + 150 µs )
n
Tactual , gap ≥ 2.0 ∗ Tactual ,data
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.
