Using Infrared Link 
 
 Communicating with the CU 
Put the BHT directly on the CU as shown below. 
 
 
 
 Communicating with other IrDA-compliant equipment 
You can also have the BHT communicate with other IrDA-compliant equipment just 
by aligning their IR ports with each other. The effective IR range and IR port angle 
may differ depending upon the target equipment, so observe the instructions given 
in manuals furnished with such equipment. 
 
 
Shield the IrDA interface from direct sunlight, intense overhead lighting 
(inverter-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. 
 
Interface connector 
(The CU is available in 
three models for the 
RS-232C, Ethernet 
(10Base-T), and USB 
interfaces.)
