5.4.3 Interfacing with the Host Computer

[ 1 ] CU-301/321

This section describes how to start communication with the host computer in System Mode. The same
can apply when you use a user program.
(1) Turn the host computer on.
(2) CU-301: Make sure that the AC adapter is plugged into a wall socket and the POWER LED is lit.
CU-321: If it is connected to the USB host, the POWER LED comes on. If it is connected to the
USB hub, turning on the hub turns on the POWER LED. If the AC adapter is plugged in,
the POWER LED is already turned on.
(3) Turn the BHT off and then put it on the CU-301/321.
(4) Turn the BHT on and run System Mode. Set the communications environments (communications
protocol, interface port, communications parameters, and protocol options). Refer to Chapter 2,
Section 2.5.3, [4.5].
Select the IrDA interface port.
(5) On the host computer, initiate a communications program (e.g., BHT-BASIC4.0 Transfer Utility or
equivalent).
(6) To transfer data stored in the BHT to the host computer, select "UPLOAD" on the SYSTEM MENU.
To transfer data from the host computer to the BHT, select "DOWNLOAD." Refer to Chapter 2,
Section 2.5.3, [ 2 ] and [ 3 ].
The BHT and the host computer start communication with each other via the CU-300. On the
CU-301/321, the DATA LED comes on upon start of communications, and after completion of
communications, the LED goes off.
