... IrDA Infrared Communication Module RPM841-H16 RPM841-H16 is an infrared communication module for IrDA Ver. 1.2 (Low Power). The infrared LED, PIN photo diode, LSI are all integrated into a single package. This module is designed with power down function and low current consumption at stand-by mode. The ultra small package makes it a perfect fit for mobile devices. ...

... LED will be turned off due to LED pulse width limiting circuit if the pulse is input from the other terminal. Therefore, don't use as the normal transmitting is impossible. Please input the pulse when both TX-RC (2pin) and TXD (3pin) are ''L''. Even if RPM841-H16 input H pulse into TXD in the state of a power down, LED does not emanate. Interface operating timing (Emitting side) (1) When TXD output for IrDA and TXD output for controller are different lines ...

... To get maximum potential from RPM841-H16, please keep in mind following instruction. • The line of RXD (4pin) should be connected at backside via through hole close to RPM841-H16 pin lead. Better not to be close to photo diode side (7pin). ⇒This is to minimize feedback supplied to photo diode from RXD. ...
