■ Transfer Utility (option)
Running on the host computer, this utility transfers files between the BHT-6000 and the
host computer. It uses the BHT-protocol as a file transfer control procedure. (For the
details about the BHT-protocol, refer to Chapter 3, Subsection 3.3.1.)
To transfer files under any of the following conditions, use Transfer Utility:
- When the BHT-6000 is placed on the CU-6000
- Via the direct-connect interface of the BHT-6000
Flash ROM and RAM
A flash ROM and RAM are mounted on the BHT-6000.
The flash ROM stores factory-written System Program and JIS Level 1 & Level 2 fonts.
You can download extension programs, user programs, and user data to either or both
of the flash ROM and RAM.
■ RAM
Programs and data stored in the RAM are backed up by a lithium battery integrated in
the BHT-6000. If the battery voltage level drops below the specified level, the RAM
cannot retain its contents so that the stored files may be damaged.
User programs can write data onto the RAM only.
In System Mode, the RAM is shown as "DRIVE A" or "A:" on the LCD. The names of
those files stored in the RAM are prefixed by "A:."
■ Flash ROM
Unlike the RAM, the flash ROM retains the stored programs and data irrespective of
the voltage level of the lithium battery. The flash ROM is limited in the frequency of
rewriting operations; frequent file rewriting exceeding approx. 10,000 times will no
longer allow rewriting. Do not rewrite the flash ROM basically more than one time a
day.
You can write data onto the flash ROM according to any of the following:
• Downloading a file in System Mode
• Copying a file from the RAM in System Mode
• Downloading a file by using XFILE statement in BHT-BASIC 3.0.
You cannot write data scanned with the BHT-6000, onto the flash ROM.
In System Mode, the flash ROM is shown as "DRIVE B" or "B:" on the LCD. The names
of those files stored in the flash ROM are prefixed by "B:."
