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 15 cm (5.9").
•
Shield the IrDA interface from direct sunlight, ambient intense lighting (inverter-driven fluorescen
t
lighting, in particular), and other potential sources of infrared radiation. Sources to watch out fo
r
include remote control units for television sets and the like.
For a host computer having no IrDA interface port, use the optical communication unit CU-200 (option)
connected to the host via an RS-232C interface cable. Put the BHT on the CU-200 as shown below.
