IFIR

IrDa Interface Module

Wireless...

Most of our single board computers have one or more IF connectors. For the wiring of the IF connector see table below.

The IFIR module allows short-distance data transfer with infrared light at transmission rates between 1200 and 115200bps. The IFIR module essentially consists of an intelligent control chip (Crystal CS8130), a transmitter and a receiver. The control chip can be serially programmed via the TxD line (mode, Baud rate, number of data bits and stop bits).

The CS8130 supports four different modes:

These four different modes allow a variety of transmission types. The LEDs can be controlled directly, allowing non-standard modulation methods and reading exotic transmission type signals directly from the receiver, passing by the decoder of the CS8130.
