Infrared (IrDA) Interface

The Little Board P6d infrared interface provides for a two-way wireless communications port using infrared as a transmission medium. 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 emitter for transmitting, and the receiver IR detector. Particular IR transducers may require additional external components.

The IrDA port uses the second serial port to drive its internal encoder/decoder. When using the IrDA interface, you cannot use serial 2 as an RS232, RS485, or RS422 port.

IrDA Connector (Part of Utility J19)

There are two popular implementations of Fast IR. One uses a separate receive line capable of receiving at the higher data rate (up to 4 Mbytes/second). The other is implemented with a mode control line. When the IR port is set for high speed, the mode select line (IRMODE) is high. This switches the external transceiver to high speed mode. The IrDA port pinout is listed in Table 2-18.
