Chapter 2. Getting Started the BHT-5000 and System Mode

■ CU-5000 and RS-232C Interface Cable

The CU-5000 is an optical communications unit which exchanges data and programs

with the BHT-5000 optically and with the host computer via the RS-232C interface

cable.

You may directly connect two BHT-5000s with each other by using a commercially

available metal cable having 3-pole mini stereo plugs (as a direct-connect interface

cable). Joining the direct-connect interface cable to an interface cable compatible with

the target host computer or modem makes it possible to directly connect the BHT-5000

with it. (NOTE: The direct-connect interface port of the BHT-5000 is not designed to

stand frequent connecting/disconnecting. You are, therefore, recommended to use

the CU-5000 where you expect to do a lot of connecting and disconnecting of the BHT-

5000 to a host computer.)

■ BHT-BASIC Extension Library (option)

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

ordinary system:

- Displaying ruled lines on the BHT-5000'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-5000 by using 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-5000. 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-5000 by using Transfer Utility.

■ Transfer Utility (option)

This Utility transfers files between the BHT-5000 and the host computer. For details,

refer to the "Transfer Utility Guide" issued separately.
