1.5 Transferring Data

Using infrared link
The BHT uses infrared rays to transfer data
BHTs).
Communication with the CU
Place the BHT on the CU (option) as shown below.
The CU-301 or CU-321 can be connected to the host with an RS-232C or USB interface cable,
respectively.
In a LAN communications system, use the combination of the LAN-support BHT* (as a LAN client) and
the CU-311 connected to Ethernet with an Ethernet interface cable.
Communication between BHTs
BHT
• 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 (5.91") or less.
• Shield the IrDA interface from direct sunlight, ambient intense 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.
