■ Using infrared link
Using infrared rays, the BHT may transfer data directly to the host computer equipped
with an IrDA interface port and other IrDA-compliant devices.
• Make sure that there is no obstruction in the light path between the BHT and any
target stations. In infrared communication, you need to keep the BHT and any
target stations within the effective infrared radiation range, usually 10 to 80 cm
(3.94 to 31.50").
• Shield the IrDA interface from direct sunlight, intense overhead lighting (in-
verter-driven fluorescent lighting, in particular), and other potential sources of
infrared radiation. Sources to watch out for include remote control units for
television sets and the like.
For a host computer having no IrDA interface port, use the optical communications
unit CU-7000 (option) connected to the host via an RS-232C interface cable. Put the
BHT in the CU-7000 as shown below.
