BHT-BASIC

BHT-Ir protocol

The BHT's IR communications device is IrDA-compliant. IrDA stands for Infrared Data

Association, which has defined hardware (IrDA Serial Infrared Physical Layer Link) and

communications protocols for IR communications.

The BHT's physical layer complies with the IrDA1.0, with a maximum transfer distance

of 0.8 m and maximum transmission rate of 115.2 kbits per second.

The BHT adopts the exclusive BHT-Ir protocol which allows you to develop user

programs for IR communications in BHT-BASIC, as can be done with conventional wire

communications.
