5.2 Infrared Communication
The BHT has a built-in infrared (IR) communication device that enables wireless transfer of programs and data both
between the BHT and the host computer and between BHTs without the need for a cable.
Infrared communication offers the following benefits over other forms of communication.
• Communication without the need for a cable
• High communication speed
• Freedom from regulations and licenses that differ from country to country when using wireless devices
Communication is performed by arranging the BHT and other IrDA-compliant devices with their IrDA (infrared)
interface ports facing one another. The communication distance and angle and so on will differ depending on the
devices used. Refer to the instructions given in the manuals provided with such equipment.
− Point − When communication is not possible, move the respective devices closer together or change the
angle of the IrDA interface ports and try again.
The BHT’s infrared communication device is IrDA-compliant. IrDA stands for Infrared Data Association, which has
defined hardware (IrDA Serial Infrared Physical Layer Link) and communication protocols for infrared communication.
The BHT's physical layer complies with IrDA1.2, with a maximum transfer distance of 0.15 m and maximum
communication speed of 115.2 kbps.
