5.4.3 Interfacing with the Host Computer
This section describes how to start communication with the host computer in System Mode. The same
may apply when you use a user program.
(1) Turn the host computer on.
(2) CU-8001: Turn the power switch on. The POWER LED will come on.
CU-8002: It is supplied with power via the RS-232C interface. It has no POWER LED.
CU-8021: If it is connected to the USB host, the POWER LED will come on. If it is connected to the
USB hub, turning on the hub will turn on the POWER LED. If the AC adapter is plugged in, the
POWER LED is already turned on.
(3) Make sure that the BHT is turned off, then put it on the CU-8000.

(4) Turn the BHT on and run System Mode. Set the communications environments (communications
protocol, interface port, communications parameters, and protocol options).
Regarding the communications protocol: When using Ir-Transfer Utility C or Ir-Transfer Utility E on
the host computer, select the BHT-Ir protocol; when using Transfer Utility, select the BHT-protocol.
Regarding the interface port: Select the IrDA interface port.
(5) On the host computer, initiate a communications program (e.g., Ir-Transfer Utility C/Ir-Transfer
Utility E/Transfer Utility, or equivalent).
(6) To transfer data stored in the BHT to the host computer, select "3: UPLOAD" on the SYSTEM
MENU in System Mode. To transfer data from the host computer to the BHT, select "2:
DOWNLOAD." (For details, refer to Chapter 2, Section 2.5.)
The BHT and the host computer will start communications with each other via the CU-8000. On the
CU-8001/8021, the DATA LED will come on upon start of communications, and after completion of
communications, the LED will go off.
(7) For the CU-8001, turn the power switch off.
