Chapter 2 Getting Started the BHT and System Menu
In addition, the BHT may operate in a radio communications system (spread spectrum communication)
by connecting with access points by a wireless local area network (wireless LAN).
• Access point:
Wireless communications base unit for the BHT
Radio Communications System
CU-7000 and RS-232C Interface Cable (option)
The CU-7000 is an IrDA-compliant communications unit which is required when your host computer is
not equipped with an IrDA interface port. The CU-7000 exchanges data and programs with the BHT
optically, and with the host computer via the RS-232C interface cable.
You may directly connect two BHTs with each other by using a commercially available metal cable
having 3-pole mini stereo plugs (as a direct-connect interface cable). You also connect the BHT directly
with the host computer or with the modem by using the direct-connect interface cable compatible with
the target equipment. (NOTE: The direct-connect interface port of the BHT is not designed to stand
frequent connecting/disconnecting. You are, therefore, recommended to use the CU-7000 where you
expect to do a lot of connecting and disconnecting of the BHT to/from a host computer.)
