Chapter 2. Getting Started the BHT-6000 and System Mode

■ CU-6000 and RS-232C Interface Cable (option)

The CU-6000 is an IrDA-compliant communications unit which is required when your
host computer is not equipped with an IrDA interface port. The CU-6000 exchanges
data and programs with the BHT-6000 optically, and with the host computer via the
RS-232C interface cable.

You may directly connect two BHT-6000s 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-6000 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-6000 is not designed to
stand frequent connecting/disconnecting. You are, therefore, recommended to use
the CU-6000 where you expect to do a lot of connecting and disconnecting of the BHT-
6000 to/from a host computer.)

■ BHT-BASIC3.0 Extension Library (option)

This Extension Library enables the following functions which cannot be handled by the
ordinary system:

Displaying ruled lines on the BHT-6000's LCD

Transmitting files by using the X-MODEM and Y-MODEM protocols.

These extension programs are stored in files named xxxx.FN3, in each file per func-
tion. You should download a xxxx.FN3 file containing the necessary function to the
BHT-6000 by using Ir-Transfer Utility C or Transfer Utility.

■ BHT-BASIC 3.0 Compiler (option)

This Compiler compiles a source program written in BHT-BASIC 3.0 by an editor of the
host computer running the MS-DOS, into the object program (user program) which
can be used in the BHT-6000. The compiled 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-6000 by using Ir-Transfer Utility C or Transfer Utility.

■ Ir-Transfer Utility C (option)

Running on the host computer, this utility transfers files between the BHT-6000 and the
host computer. For its file transfer control procedure, the utility uses the BHT-Ir
protocol which complies with the serial IR physical layer standards of IrDA Serial
Infrared Data Link Standard, Version 1.0 (IrDA-SIR 1.0). (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.)

When the BHT-6000 is separated from the CU-6000

When the BHT-6000 is placed on the CU-6000

When transferring via the direct-connect interface of the BHT-6000 (Maximum
transmission speed is 38400 bps.)
