Infrared Communication - Denso BHT-8000 User Manual

3.1 Infrared Communication

The BHT has an integrated infrared (IR) communications device which enables wireless transfer of
programs and data between the BHT and the host PC and between the BHTs, 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 may communicate with other IrDA-compliant equipment just by aligning their IrDA interface
ports with each other. The effective IR range and IrDA port angle may differ depending upon the target
equipment, so observe the instructions given in manuals furnished with such equipment.
If IR transfer fails, bring the BHT closer to the target station or change the IrDA interface port angle,
and try again.
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 IrDA1.2 Low power, with a maximum transfer distance of
0.15 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.
