Chapter 2. Getting Started the BHT-7000 and System Mode
■ 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-7000 optically, and with the host computer via the
RS-232C interface cable.
You may directly connect two BHT-7000s 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-7000 directly with the host computer or with the
modem by using the direct-connect interface cable compatible with the target equip-
ment. (NOTE: The direct-connect interface port of the BHT-7000 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-
7000 to/from a host computer.)
■ BHT-BASIC Compiler (option)
This Compiler compiles a source program written in BHT-BASIC by an editor of the
host computer running the MS-DOS, into the object program (user program) which
can be used in the BHT-7000. The compiled and linked program file is named "XXX.PD3."
(XXX: File name you can set arbitrarily under the MS-DOS rules) You should download
it to the BHT-7000 by using Ir-Transfer Utility C/Ir-Transfer Utility E/Transfer Utility.
■ Ir-Transfer Utility C (option)
Running on the host computer, this utility transfers files between the BHT-7000 and the
host computer. For its file transfer control procedure, the utility uses the BHT-Ir
protocol. (For the details about the BHT-Ir protocol, refer to Chapter 3, Subsection
3.3.2.)
To transfer files under any of the following conditions, use Ir-Transfer Utility C:
- At transmission speeds of 115200 or 57600 bps (This may be impossible de-
pending upon the host computer type.)
- Via the CU-7000
- When transferring via the direct-connect interface of the BHT-7000
