•When reading bar codes, slightly tilt the
BHT-6000 down towards you relative to
those codes, as illustrated at right.
•If the BHT-6000 fails to read, change the reading angle of the bar-code reading
window or the distance from bar codes, and try it again.
•To read bar codes wider than the readable area of the bar-code reading window,
pull the bar-code reading window away from bar codes for long-range scanning
so that the entire bar code comes into the illumination range covered by the
illumination LED. The BHT-6000 can read bar codes at a maximum distance of 24
cm (9.4") [35 cm (13.8") for the BHT-6000D]** from the bar-code reading window.
** Under the following conditions:
- Ambient illuminance: 500 lux (fluorescent lamp)
- ITF conforming to the UPC Shipping Container Code
- PCS value: 0.9 or more
- Minimum narrow bar width: 1.2 mm min. (47.2 mils min.)
•The bar code reading procedure may differ depending upon the application
used, so follow the application’s manual.
•Before reading labels, clean them if stained.
•Avoid using the BHT-6000 in direct sunlight. The BHT-6000 might fail to read
correctly.
•To read bar codes on curved surfaces, apply the bar-code reading window to the
center of each bar code at a right angle.
•The further you pull the bar-code reading window away from bar codes, the
wider the quiet zones required, in relation to bar code lengths in the illumination
range covered by the illumination LED.
1.1 Reading Bar Codes
Turn on the BHT power, bring the bar-code reading window up to the bar code to be
scanned, and press the M1 or M2 key (Magic key 1 or 2)*. The BHT-6000 lights the

1.5 Communicating via the Optical In-
terface
■ Optical Communications with the BHT-6000
The BHT-6000 communicates using an IR beam, so make sure that there is no obstruc-
tion in the light path between the BHT-6000 and any target stations.
In the IrDA communications mode, you need to keep the BHT-6000 and any target
stations within the effective light emission range, usually 10 to 80 cm.
■ Communicating with the CU-6000
The optional CU-6000 is an IrDA-compliant communications unit. For optical commu-
nications, you may either keep the BHT-6000 and CU-6000 separated by 10 to 80 cm
with their IR ports facing each other, or put the BHT-6000 directly on the CU-6000 as
shown below.
■ Communicating with other IrDA-compliant equipment
You can also have the BHT-6000 communicate with other IrDA-compliant equipment
just by aligning their IR ports with each other. The effective IR range and IR port angle
may differ depending upon the target equipment, so observe the instructions given in
manuals furnished with such equipment.
If transfer using the BHT-6000 fails, bring it closer to the target station or change the IR
port angle, and try again.
Communications failures might be caused by highly intensive light emitted from
ceiling (inverter-driven fluorescent) lamps or direct sunlight. Take care to prevent
such interference light from coming into the IR ports of the BHT-6000 and IrDA-
compliant equipment, including the CU-6000.
Do not use any TV remote control in the vicinity of the IR communications system.
Doing so may interfere with the communications.

2.1 BHT-6000 System Configuration
The BHT-6000 barcode data collection system requires the following hardware as well
as the BHT-6000 Bar Code Handy Terminal (which reads bar codes and accepts keypad
entry) as illustrated below:
•Host computer: Allows you to edit, manage and download programs and
data, as well as downloading extension programs.
For host computers without IrDA interface ports, the optional CU-6000 optical commu-
nications unit and RS-232C interface cable are available.
•CU-6000 (option): Exchanges programs and data with the BHT-6000 optically
and with the host computer via the RS-232C interface.
•RS-232C interface cable: Connects the CU-6000 and the host computer.
The basic software required for operating the BHT-6000 is "System Mode" which is
resident in the flash ROM.
Optional software includes the BHT-BASIC 3.0 Extension Library, BHT-BASIC 3.0 Com-
piler, Ir-Transfer Utility C, and Transfer Utility. (Each software is provided in a floppy

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.)
10
■ 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:."

■ System Programs
The system programs include the following three sets of programs:
Drivers
Drivers is a set of programs that directly controls the BHT-6000 hardware. It may be
called up by the BHT-BASIC 3.0 Interpreter or System Mode.
BHT-BASIC 3.0 Interpreter
The interpreter interprets and executes instructions in user programs written in BHT-
BASIC 3.0.
System Mode
System Mode is a system program exclusively designed for the effective use of user
programs in the BHT-6000. It sets up the execution environments for those programs;
e.g., it prepares downloading/uploading conditions, sets the calendar clock, and tests
the BHT-6000 components including the LCD, beeper, and keypad. Shown below is the
System Mode menu (SYSTEM MENU).

■ JIS Level 1 and Level 2 Font Files
These files contain font data required for displaying Kanji characters on the LCD.
The BHT-6000 has no Kanji ROM, so it stores Kanji fonts in the flash ROM.
The BHT-6000 can display not only the Kanji characters in the conventional standard-
size font (16 dots wide by 16 dots high) but also them in the small-size font (12 dots
wide by 12 dots high) in application programs.
■ Extension Programs
These programs extend the system programs by adding new functions which cannot
be handled by the ordinary system.
To download desired extension programs in the BHT-BASIC Extension Library, you
need to use Ir-Transfer Utility C or Transfer Utility.
■ User Programs
You can develop application programs to meet individual job requirements by using
the BHT-BASIC 3.0 Compiler. To download those user programs to the BHT-6000, use
Ir-Transfer Utility C or Transfer Utility.

Chapter 2. Getting Started the BHT-6000 and System Mode
2.2 Infrared Communications
The BHT-6000 has an integrated infrared (IR) communications device which enables
wireless transfer of programs and data between the BHT-6000 and the host computer
and between the BHT-6000s, instead of the conventional wire transfer.
The IR communications device features the following:
•Wireless communications
•Small and lightweight design
•High transmission speed
•Freedom from the codes/regulations and licenses which differ from country to
country, unlike radio devices
The BHT-6000’s IR communications device is IrDA-compliant. IrDA stands for Infrared
Data Association, which has defined hardware (IrDA Serial Infrared Physical Layer
Link, IrDA-SIR) and communications protocols for IR communications.
The BHT-6000’s physical layer complies with the IrDA-SIR 1.0, with a maximum trans-
fer distance of 1 m and maximum transmission rate of 115.2 kbits per second.
The BHT-6000 adopts the exclusive BHT-Ir protocol which allows you to develop user
programs for IR communications in BHT-BASIC 3.0, as can be done with conventional
wire communications.

REFERENCE
When you first load batteries (or battery cartridge) after purchase or you load them
(it) after leaving the BHT-6000 unused for a long time, do not remove the batteries
(battery cartridge) within 24 hours after that loading.
Do not leave the BHT-6000 with no batteries or battery cartridge loaded for a long
time. Doing so may cause loss of memory contents as well as a system error while
showing the message "System error! Contact your administrator. Note the error
drive. (DRIVE X)" on the LCD.
When disposing of the battery cartridge, cover the terminal pins with vinyl tape to
prevent short-circuit.
An early upload of gathered data is recommended, since the data stored in the RAM
might be affected by the so-called "soft error" or other environmental phenomena.
The BHT-6000 has an integrated rechargeable lithium battery which backs up
the memory in the BHT-6000 when no batteries or battery cartridge is loaded
or the voltage level of the batteries or battery cartridge drops below the
specified level. The lithium battery is automatically charged by the batteries
or battery cartridge.

NOTE Preparation for Copying between the BHTs
Before downloading to the BHT-6000 from another BHT-6000, make the fol-
lowing preparation:
•
At each BHT-6000, set the interface port. The default is an optical interface
(OPT).
Interface setting procedure: Starting on the SYSTEM MENU, select "4:SET
SYSTEM," "6:COM," and "3:COM PORT." On the SET COM PORT screen,
select the optical interface (OPT) or direct-connect interface (IFC) of "2:SYS-
TEM MODE."
•When using the direct-connect interface, pull out the connector cover on
each BHT-6000 to expose the direct-connect interface port. Connect the
BHT-6000s via those ports with the direct-connect interface cable (having 3-
pole mini stereo plugs). For the details about the cable, refer to Chapter 3,
Section 3.1.
•On the uploading BHT-6000, run System Mode and select "3:UPLOAD" and
"5:HT<->HT COPY."
36
With this screen displayed, the BHT-6000 waits for
a file to be downloaded.

downloading type--(A:), (B:), or (HT<->HT) indicat-
ing the downloading to the RAM, to the flash ROM,
or copying between the BHTs, respectively. The
screen at left shows that "1: DRIVE A" has been
selected.
Upon start of optional Ir-Transfer Utility C, Trans-
fer Utility or equivalent program (upon receipt of
an ENQ code from the host computer), the BHT-
6000 displays the screen shown at left.
(Refer to the "Ir-Transfer Utility C Guide" or "Trans-
fer Utility Guide.")
While the downloading operation is in progress,
the screen shown at left is displayed indicating the
file name and the number of received records/the
total number of records.
To abort the downloading operation, press the
C key. The screen will switch back to the
DOWNLOAD menu.
Upon completion of downloading, the number of
received records becomes equal to the total
number of records and the beeper beeps once.
Press the C key to return to the DOWNLOAD
menu.
If the host computer downloads another new file
(if the BHT-6000 receives an ENQ code) when this
screen is displayed, the BHT-6000 starts receiving
it.
(Refer to the "Ir-Transfer Utility C Guide" or "Trans-
fer Utility Guide.")
If you have selected "3: HT<->HT COPY" on the
DOWNLOAD menu, a sequence of the above
screens will be repeated by the number of files to
be downloaded.

Black-and-white inverted label reading function (INVERT)
This function makes it possible to read white bars on a black background.
Activating this function might increase the frequency of bar-code reading errors.
This function can usually be set to OFF.
Touch scanning/long-range scanning (TOUCH READ)
You may select touch scanning or long-range scanning. The touch scanning is a
method in which you bring the bar-code reading window to a bar code to be scanned.
The long-range scanning allows you to read bar codes wider than the readable area of
the bar-code reading window by pulling the bar-code reading window away from bar
codes.
If "TOUCH READ" is set to ON, the reading speed increases in touch scanning. In long-
range scanning, however, this setting may decrease the reading speed and efficiency
when the ambient illuminance is low or too high.
If "TOUCH READ" is set to OFF, the BHT-6000 can scan bar codes irrespective of the
ambient illuminance. This setting, therefore, is suitable for long-range scanning. Note
that the scanning speed will slightly decrease.
Decode level (DECODE LEVEL)
You may set the recognition level. Decreasing the level value increases the bar-code
reading efficiency, but the BHT-6000 might misread low-quality bar codes (split or
stained). To the contrary, increasing the level value decreases the bar-code reading
efficiency, but it precludes almost all possibilities of misreading.
The setting range of the level value is from 1 to 9 and the default is 3.

3.1 RS-232C Interface Specifications
[ 1 ] Interface Connector and Pin Assignment
The BHT-6000 has a direct-connect interface port which is connectable to the 3-pole
mini stereo plug (ø2.5 mm or 0.1") and supports a subset of the RS-232C interface as
shown below.
Using a direct-connect interface cable having the mini stereo plugs makes it possible
to connect the BHT-6000 to a host computer (or another BHT-6000) directly without
any routing through the CU-6000.

NOTE
The direct-connect interface port is not designed to stand frequent connecting/
disconnecting. Do not plug and unplug basically more than one time a day;
otherwise, the service life of the plug will shorten. To connect the BHT-6000 to a
host computer (or another BHT-6000) frequently, use the CU-6000.
Allow the specified signals only to enter the direct-connect interface port. Entry of
other signals will result in a failure or malfunction of the BHT-6000.

3.2 Basic Communications Specifica-
tions and Parameters
3.2.1 Basic Communications Specifications

data with a host computer through the CU-6000 (optical interface) or direct-connect
interface cable.

57600, or 115200 bps
■ Synchronization
For accurate data transaction, it is very important to synchronize the transmission
between the sender and receiver. To do this, it is required to previously define the
bit order and position, the character length, and the beginning and end of the
character to be transmitted.
The start-stop synchronization is an asynchronous system which synchronizes
each character as a unit; that is, it externally adds start and stop bits to the leading
and trailing bit positions of the character to be transmitted, respectively. A clock
starts counting on receiving the start bit and it falls into a non-communication state
on receiving the stop bit. The number of the stop bits is selectable (1 or 2 bits).
■ Transmission Speed
Maximum number of bits to be transmitted per second. Expressed in bps (bits per
second).
■ Optical Interface Communications Range
The optical interface's maximum effective range is 80 cm with the IR beam within a
10˚ angle of divergence.

Chapter 3. Communications Operations of BHT-6000
■ Transmission Code and Bit Order
All characters should be coded to 7- or 8-bit code for data transmission. The
standard data exchange code of the BHT-6000 is JIS 7- or 8-bit code. The transmis-
sion bit order is LSB (Least significant bit) first.
What follows is an example for transmitting character A (41h, 01000001b) coded to
JIS 8-level code with an even parity and a single bit each for start and stop bits.
Parity bit
Stop bit
Start bit
■ Response Method
When two devices initiate communications, they exchange signals for correct data
transmission. This procedure is called "handshaking." The sender sends a control
code ENQ (05h) to the receiver meaning "Are you ready to receive data?," and the
receiver replies to it with a control code ACK (06h) or NAK (15h) meaning "Positive"
or "Negative" for starting data transmission, respectively. This sequence is also
called "data link establishment phase."
■ Vertical Parity
A vertical parity bit is a redundancy bit which is added to every character to be
transmitted in order to check that data has been transmitted accurately. The parity
bit should be set to "1" or "0" depending upon the parity parameter setting, to make
the number of set bits in the character even or odd. The receiver counts the
number of set bits in the transmitted character code to make sure that it has the
selected number (even or odd) of set bits.
The vertical parity bit is positioned immediately following the MSB (Most signifi-
cant bit) as shown below.

* The 300 bps and 600 bps are not available in System Mode.
In System Mode
Refer to Chapter 2, Subsection 2.5.3, "Detailed Description of the Functions in System
Mode," [ 4.6 ] Setting the communications environments.
In BHT-BASIC 3.0
To set the transmission speed, character length, vertical parity, and stop bit length (To
set the transmission speed only for the optical interface), use the OPEN "COM:"
statement in BHT-BASIC 3.0.
OPEN "COM: ... "Opens the interface port selected in System Mode.
OPEN "COM1: ... "Opens the optical interface port for data transmission
routing through the CU-6000, irrespective of the setting
in System Mode.
OPEN "COM2: ... "Opens the direct-connect interface port for data trans-
mission, irrespective of the setting in System Mode.
Note that it is impossible to open both the optical interface port and the direct-connect
interface port concurrently.
Through the interface port opened by the OPEN "COM:" statement, the XFILE
statement transmits a designated file.
87
Chapter 3. Communications Operations of BHT-6000
3.3 Communications Protocols
The BHT-6000 supports both the BHT-protocol and the BHT-Ir protocol for file trans-
mission.
3.3.1 BHT-protocol
[ 1 ] Overview
The BHT-protocol is the communications procedure used to transmit files between the
BHT-6000 and a host (or between the BHT-6000s). It adopts the response method
using ACK/NAK codes.
The BHT-protocol is composed of a defined set of the control character sequences
including the following three phases:
Phase 1: Establishment of data link
The sending station confirms that the receiving station is ready to
receive data.
Phase 2: Data transmission
The sending station transmits data to the target receiving station.
Phase 3: Release of data link
The sending station confirms whether or not all of the transmitted
data has been correctly received by the receiving station. If yes, the
sending station terminates the data transmission and releases the
data link.
88
[ 2 ] Control Characters
The control characters are classified into two groups: transmission control characters
and text control characters.
(1) Transmission control characters
The transmission control characters listed below are used to compose transmission
control sequences in phases 1 through 3.
Symbol Value Meaning Function
EOT 04h End Of Transmission Releases a data link (Phase 3).
Requests abort of transmission
(Phase 2).
ENQ 05h Enquiry Requests establishment of a data link
(Phase 1).
Prompts the receiver to respond to
the sent text (Phase 2).
ACK 06h Acknowledge Acknowledgment response to ENQ
(Phase 1).
Acknowledgment response to text
(Phase 2).
Acknowledgment response to EOT
(Phase 3).
NAK 15h Negative Acknowledge Negative acknowledgment response
to ENQ (Phase 1).
Negative acknowledgment response
to text (Phase 2).
■ Transparency
The BHT-6000 uses the non-transparent mode which handles the control characters
and codes (e.g., STX, ETX, and SOH) as starting or ending markers and does not
allow them to be transmitted as normal data in the transmission texts.
89
Chapter 3. Communications Operations of BHT-6000
(2) Text control characters
The text control characters are used to format transmission texts. In the BHT-protocol,
they include the following headers and a terminator.
Symbol Value Meaning Function
SOH 01h Start Of Heading Indicates the start of heading text (Phase
2).
STX 02h Start Of Text Indicates the start of data text (Phase 2).
ETX 03h End Of Text Indicates the end of data text (Phase 2).
You may designate headers and a terminator with the protocol functions in BHT-BASIC
3.0. If you designate none of them in a user program, the BHT-6000 may apply those
as listed above. Refer to the "BHT-BASIC 3.0 Programmer's Manual."

[ 3 ] Basic Format of Transmission Messages
Basically, the BHT-6000 transmits data as units of a file. First, it transmits a heading
text which includes the attribute information of a file (e.g., file name and the number of
data texts) to be transmitted. Following the heading text, it transmits the data text in
the file. A heading text and data text comprise a text.
In actual text transmission, the text is divided into several blocks, then a header and
terminator are added to each block. If the serial number management or error
checking by BCC (Block Check Character) is required, the serial number or BCC is also
added to each block, respectively. This procedure forms a transmission block. A set of
transmission blocks makes up one transmission message.
Shown below is an example of a transmission message formed with the BHT-protocol.

In the above figure, SOH, STX, and ETX are text control characters as described in [ 2 ]
Control Characters. A serial number is expressed by a five-digit decimal number,
starting from 00001 to 32767, and identifies transmitted data texts. For the BCC, refer
to [ 6 ] BCC for Horizontal Parity Checking.

[ 6 ] BCC for Horizontal Parity Checking
To check whether data has been transmitted accurately, the BHT-6000 supports hori-
zontal parity checking for every transmission block.
In horizontal parity checking, a horizontal parity byte so called BCC (Block Check
Character) is suffixed to an ETX of every transmission block.
In the BHT-protocol, every parity bit of BCC is set so that all set bits at the same bit
level (including a parity bit) in the characters contained in the transmission block have
an even number by binary addition, excluding SOH, STX, and functions SOH$ and
STX$.
(For details about SOH$ and STX$ which are protocol functions unique to BHT-BASIC
3.0, refer to the "BHT-BASIC 3.0 Programmer's Manual.")

3.3.2 BHT-Ir Protocol
[ 1 ] Overview
The BHT-Ir protocol is the communications procedure for the serial infrared link, which
is used to transmit files between the BHT-6000 and a host (or between the BHT-6000s).
It adopts the response method using ACK/NAK codes. The BHT-Ir protocol can be used
also for communications through the direct-connect interface.
The BHT-Ir protocol is composed of a defined set of the control character sequences
including the following three phases:
Phase 1: Establishment of data link
The sending station confirms that the receiving station is ready to
receive data.
Phase 2: Data transmission
The sending station transmits data to the target receiving station.
Phase 3: Release of data link
The sending station confirms whether or not all of the transmitted
data has been correctly received by the receiving station. If yes, the
sending station terminates the data transmission and releases the
data link.
104
[ 2 ] Control Characters
The control characters are classified into two groups: transmission control characters
and text control characters.
(1) Transmission control characters
The transmission control characters listed below are used to compose transmission
control sequences in phases 1 through 3.
Symbol Value Meaning Function
DLE EOT 1004h End Of Transmission Releases a data link (Phase 3).
Requests abort of transmission
(Phase 2).
DLE ENQ 1005h Enquiry Requests establishment of a data link
(Phase 1).
Prompts the receiver to respond to
the sent text (Phase 2).
DLE ACK 1006h Acknowledge Acknowledgment response to DLE
ENQ (Phase 1).
Acknowledgment response to text
(Phase 2).
Acknowledgment response to DLE
EOT (Phase 3).
DLE NAK 1015h Negative Acknowledge Negative acknowledgment response
to DLE ENQ (Phase 1).
Negative acknowledgment response
to text (Phase 2).
WACK 103Bh Wait for Acknowledge Requests suspension of data recep-
tion during erasure of the flash ROM.
■ Transparency
The BHT-6000 uses the transparent mode which allows the control characters and
codes (e.g., STX, ETX, SOH, and DLE) to be transmitted as normal data in the
transmission texts.
To transmit a DLE as normal data, type DLE DLE per DLE.
105
Chapter 3. Communications Operations of BHT-6000
(2) Text control characters
The text control characters are used to format transmission texts. In the BHT-Ir
protocol, they include the following headers and a terminator.
Symbol Value Meaning Function
DLE SOH 1001h Start Of Heading Indicates the start of heading text (Phase
2).
DLE STX 1002h Start Of Text Indicates the start of data text (Phase 2).
DLE ETX 1003h End Of Text Indicates the end of data text (Phase 2).
In the BHT-Ir protocol, you cannot change the values of the headers and terminator
with the protocol functions in BHT-BASIC 3.0.

[ 3 ] Basic Format of Transmission Messages
Basically, the BHT-6000 transmits data as units of a file. First, it transmits a heading
text which includes the attribute information of a file (e.g., file name and the number of
data texts) to be transmitted. Following the heading text, it transmits the data text in
the file. A heading text and data text comprise a text.
In actual text transmission, the text is divided into several blocks, then a header,
terminator, serial number, receiver station’s ID, and CRC-16 (Cyclic Redundancy Check)
are added to each block. This procedure forms a transmission block. A set of
transmission blocks makes up one transmission message.
Shown below is an example of a transmission message formed with the BHT-Ir
protocol.
In the above figure, DLE SOH, DLE STX and DLE ETX are text control characters as
described in [ 2 ] Control Characters. An ID denotes the ID number of the receiver
station, expressed by two bytes. A serial number is expressed by a five-digit decimal
number, starting from 00001 to 32767, and identifies data texts. For the CRC-16, refer
to [ 6 ] CRC.
You can use the control characters for expressing IDs serial numbers, or text data.
For DLEs, type DLE DLE per DLE.

Data transmission may accidentally involve various types of errors. The BHT-Ir proto-
col is designed to recover from those errors as frequently as possible. What follows is
the BHT-Ir protocol for phases 1 through 3.
Phase 1: Establishment of Data Link
■ Normal phase 1
The sending station transmits a sequence of DLE ENQ and IDm (sending station’s
ID) to the receiving station. Upon receipt of a sequence of DLE ACK and IDs
(receiving station’s ID) from the receiving station, the sending station shifts to
phase 2.

■ Phase 1 with iterated transmission of DLE ENQ and IDm due to no re-
sponse or invalid response
If the sending station receives no response or any invalid response from the
receiving station in response to the sent sequence of DLE ENQ and IDm, it iterates
sending of the sequence at 0.5-second intervals up to 60 times.
If the sending station receives a sequence of DLE ACK and IDs before sending the
sequence of DLE ENQ and IDm 60 times, it shifts to phase 2.

■ Abnormal termination of phase 1 (Abort of phase 1)
If the sending station receives no sequence of DLE ACK and IDs from the receiving
station after sending a sequence of DLE ENQ and IDm 60 times in succession, it
sends a sequence of DLE EOT and IDm to the receiving station after 0.5 second
from the 60th sequence of DLE ENQ and IDm, then aborts the message transmis-
sion abnormally.

Phase 2: Data Transmission
■ Normal phase 2
The sending station first sends a transmission block containing the heading text.
Each time the sending station receives a sequence of DLE ACK and IDs from the
receiving station, it sends a transmission block containing the data texts as shown
below. Upon receipt of a sequence of DLE ACK and IDs in response to the last
transmission block (data text n), the sending station shifts to phase 3.
If a transmission message contains no data text, the sending station transmits the
heading text only.

■ Phase 2 with suspension of data reception for erasure of the flash ROM
If the receiving BHT-6000 requires the flash ROM to be erased for receiving
downloaded files, it sends a sequence of WACK and IDs to the sending station to
suspend the data transmission.
Upon receipt of the sequence of WACK and IDs, the sending station stops the data
transmission until any response comes from the receiving station for one minute.
If no response comes within one minute, the sending station sends a sequence of
DLE EOT and IDs and then aborts the current transmission.

Chapter 3. Communications Operations of BHT-6000
[ 6 ] CRC
To check whether data has been transmitted accurately, the BHT-Ir protocol supports
CRC (Cyclic Redundancy Check) which employs the CRC-16 generating system. In
CRC, a CRC character is suffixed to a sequence of DLE ETX of every transmission block.
Operands for CRC-16
The CRC generates CRC-16 from all bytes of a transmission block excluding DLE SOH
or DLE STX characters (which are at the head of a transmission block), DLE character
of DLE ETX and DLE character of DLE DLE in the text.
CRC operation
The CRC system generates CRC-16 as follows: It multiplies the polynomial formed by
aligning all of the bits starting from the LSD of the first byte to the MSD of the last byte
in a transmission block in descending order, by X16. Next, divide the polynomial by
the generative polynomial X16 + X15 + X2 + 1. The remainder is the value of CRC-16.
Shown below is a data text transmission block and operands for CRC-16 generation.

(2) Data text
The total length of all data fields plus the number of the character count bytes (= the
number of the fields) should be 255 bytes or less.
When you transfer five 50-digit (50-byte) fields, for example, the total length of all
data fields is 250 (50 x 5) bytes and the number of the character count bytes is 5.
Accordingly, the total is 255, so you can transfer the file.

Chapter 5. Handling the CU-6000 (Option)
5.5 Charging the Ni-MH Battery Car-
tridge (using the CU-6001)
You may charge Ni-MH battery cartridges either loaded in the BHT-6000 or all by
themselves.
Service Life of Ni-MH Battery Cartridge:
Ni-MH batteries used in the battery cartridge will gradually deteriorate during the
repeated cycles of charging and discharging due to its properties, even under
normal use. When the battery service period becomes shortened due to its deterio-
ration even if it has been charged for the specified hours, replace the battery
cartridge with a new one. Generally, it is necessary to replace the battery cartridge
after it has undergone approx. 200 cycles of charging and discharging operation.
Memory Effect:
If a Ni-MH battery undergoes many cycles of imperfect charging and discharging
(e.g., one-hour recharge followed by one-hour use), the service period may become
shortened before the service life is really expired, just as the battery memorizes the
use conditions. It is called "Memory Effect." The memory effect can be avoided
by discharging a Ni-MH battery fully before charging.
For the Ni-MH battery cartridge, use the CU-6001 or C-600 for fully discharging
and recharging.
NOTE
5.5.1 Ni-MH Battery Cartridge Loaded in the BHT-
6000
(1) Turn on the CU-6001.
(2) Place the BHT-6000 loaded with a Ni-MH battery cartridge onto the CU-6001.
The CU-6001 lights the CHG1 LED and starts charging.
After approx. ten hours of charging, the CHG1 LED starts flashing at 2-second
intervals, indicating that charging is completed.

generate heat, rupture, or burn.
•Do not insert or drop foreign materials such as
metals or anything inflammable through the
openings (vents or battery cartridge slot) into
the CU-6000.
Doing so could result in a fire or electrical shock.
The CU-6001 can charge Ni-MH battery cartridges in either of the following two ways:
-Fully discharging and then charging* [ 1 ]
-Charging only [ 2 ]
*Fully discharging and then charging batteries
can prevent "Memory Effect" as described at
the beginning of Section 5.5.
To select [ 1 ], first power on the CU-6001 and then load a Ni-MH battery cartridge into
it. To select [ 2 ], first load a Ni-MH battery cartridge into the CU-6001 and then power
it on.

[ 1 ] Fully Discharging (Refresh) and then Charging
(1) Power on the CU-6001. The POWER LED comes on.
(2) Load a Ni-MH battery cartridge into the CU-6001 from the battery cartridge slot.
The CU-6001 flashes the CHG2 LED at 0.4-second intervals and starts discharging
the cartridge. The discharging time differs depending upon the battery condition,
but never more than three hours.
Upon completion of discharging, the CHG2 LED comes to stay on and the CU-
6001 starts charging.
After approx. ten hours of charging, the CHG2 LED starts flashing at 2-second
intervals, indicating that the charging is completed.
(3) Take out the battery cartridge.

[ 2 ] Interface Cable Connection
As illustrated below, connect the CU-6000 (which is joined with the BHT-6000) to a host
computer with a cross-mode cable. To connect it to a modem, use a straight-mode
cable.
DTE and DCE
In the RS-232C interface specifications, the DTEs (Data Terminal Equipment) shall be
generally connected with each other by a cross-mode cable; the DTE and DCE (Data
Circuit-terminating Equipment) shall be connected with each other by a straight-mode
cable.
The DTE is one piece of equipment connected at both ends of a communications line
as a sender or receiver of data (such as CU-6000 joined with the BHT-6000 and a host
computer).
The DCE is one piece of equipment connected to the intermediate point between the
DTE and the communications line. It terminates communications lines and exchanges
information between those lines without any change in contents (such as modem).

Alphabet Input Procedure
To activated or deactivate the alphabet input func-
tion, issue OUT statement in a user program.
As shown at right, each of 0-9 numerical keys and
period key is assigned three characters. For exam-
ple, the 7 key is assigned A, B, and C.
To designate one of three assigned characters,
use the M1 or M2 key. Note that the trigger
switch function (default) or no function should be
assigned to the M1 or M2 key to be used.

/$%
Alphabet input procedure
(1) Activating the alphabet input function with OUT statement
In a user program, issue the OUT statement which sets 1 to bit 0 of port 5. (To
deactivate the function, issue the OUT statement which sets 0 to bit 0 of port 5.)
To activate: OUT 5, &h1
To deactivate: OUT 5, &h0
The default setting of the alphabet input function is "deactivated."
(2) Entering alphabetic characters from the keypad
1) Find a target key which is assigned an alphabetic character to be inputted, and
then check the position of the character (Left, Center, or Right) relative to the
three characters assigned to the target key.
2) Designate the character position by using the M1 or M2 key and then press
the target key.
How to use the M1 or M2 key
Pressing the M1 or M2 key cycles through the shift guidance blocks Left ,
Center , and Right on the LCD as shown below.
Left Center Right
The shift guidance block will
appear on the top or bottom line,
depending upon the current
cursor position. That is, if the
cursor lies on any of the lower
lines, the shift guidance block will
appear on the top line; if it lies on
any of the upper lines, the block
will appear on the bottom line.
158
The shift guidance block appears only while the M1 or M2 key is held down.
Therefore, you should press the target key while holding down the M1 or
M2 key.
To enter an N character, for example, use the M1 or M2 key to display the
Center on the LCD. While displaying the Center , press the 5 key.
•During the alphabet input operation, you can use the BS , C , and numerical
keys as usual.
•For displaying the shift guidance block Right when the status indication is set
to ON, the BHT-6000 overwrites the status indication with the shift block.
•The activated or deactivated state of the alphabet input function will be re-
sumed. The shift block will not be resumed.
