The line of RXD (6pin) should be connected at backside via through hole close to RPM872-H12 pin lead. Better not to
As for C1 between 3-4 pin should be placed close to RPM872-H12.
Better to be placed more than 1.0cm in radius from photo diode (pin1 side) and also away from the parts which
Please be sure to set up the TXD (7pin) input to be “L” (under 0.3V) except transmitting data
Power down current might increase if exposed by strong light (ex. direct sunlight) at powerdown mode.
Please use by the signal format which is specified by IrDA Ver1.2 (Low Power).
There might be on error if used by different signal format.
Please pay attention to the lens carefully. Dusts of scratch on the lens may effect the characteristics of product.
Please handle it with care.
