The Little Board P6d IrDA interface supports both SIR (Serial Infrared) and FIR (Fast Infrared) standards . The SIR standard allows serial communication at baud rates up to 115K Baud. The FIR standard allows data rates up to 4Mbps. Requirements for an IrDA Interface On the Little Board P6d module, the IrDA physical link hardware consists of an IR transmit encoder and IR receiver decoder. To implement an IrDA port, the OEM must supply an IR transducer, which consists of the output driver and IR e
