■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 optically, and with the host computer via the RS-232C interface cable.
You may directly connect two BHTs 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 directly with the host computer or with the modem by using the direct-connect interface cable compatible with the target equipment. (NOTE: The direct-connect interface port of the BHT 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 to/from a host com- puter.)
■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. The compiled and linked program file is named "XXX.PD3." (XXX: File name you can set arbitrarily under the MS-DOS rules) You should down- load it to the BHT 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 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 3.5.2.)
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 is placed on the CU-7000
-Via the direct-connect interface of the BHT
■Ir-Transfer Utility E (option)
Running on the host computer, this utility transfers files between the BHT 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 3.5.2.)
To transfer files under any of the following conditions, use Ir-Transfer Utility E:
-Via an external IR transceiver
-Via an IR port integrated in a computer
