IRM-H1xx/TR2 SERIES
The Notice of Application:
Transmission remote control signal consist of four parts: Encode Part, IR Transmitter Source, IRM
device, Decode Part
1. When IRM-H1xx 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. Minimum Burst Length T
burst
(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.
If the above items hardly assure of its application, it’ll cause NG(no good) message from the edge of
signal.
Test Method：
：
The specified electro-optical characteristics is satisfied under the following
Conditions at the controllable distance.
Measurement place
A place that is nothing of extreme light reflected in the room.
External 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)
Standard 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).
Measuring system
According to the measuring system shown in Fig.-3
