Chapter 2. Getting Started the BHT-6000 and System Mode
2.2 Infrared Communications
The BHT-6000 has an integrated infrared (IR) communications device which enables
wireless transfer of programs and data between the BHT-6000 and the host computer
and between the BHT-6000s, instead of the conventional wire transfer.
The IR communications device features the following:
•Wireless communications
• Small and lightweight design
• High transmission speed
• Freedom from the codes/regulations and licenses which differ from country to
country, unlike radio devices
The BHT-6000’s IR communications device is IrDA-compliant. IrDA stands for Infrared
Data Association, which has defined hardware (IrDA Serial Infrared Physical Layer
Link, IrDA-SIR) and communications protocols for IR communications.
The BHT-6000’s physical layer complies with the IrDA-SIR 1.0, with a maximum trans-
fer distance of 1 m and maximum transmission rate of 115.2 kbits per second.
The BHT-6000 adopts the exclusive BHT-Ir protocol which allows you to develop user
programs for IR communications in BHT-BASIC 3.0, as can be done with conventional
wire communications.
