1.1 Reading Bar Codes
Turn on the BHT power, bring the bar-code reading window to the bar code to be
scanned, and press the trigger switch. The BHT emits a laser light to scan the bar
code.
When the BHT has read the bar code successfully, the indicator LED will illuminate in
green.

Trigger switch (M3 key)*
PW key
* The trigger switch function is
assigned to both of the M3 and
M4 keys by default.
• If the BHT fails to read due to specular effects or other
factors, change the scanning angle of the reading window or the distance from codes as shown at right, and
try it again. (Specular effects occur when the reflection of the light from the bar code becomes excessively strong. This can easily happen when the reflecting surface is polished or covered with vinyl.)
• Keep the BHT at a distance from a target bar code so that the bar code comes
within approx. 90% of the laser scanning range (line length).
• The BHT can read bar codes at a maximum distance of 56 cm (22.0")** from the
bar-code reading window.
**Under the following conditions:
- Ambient illuminance: 500 x (Xenon lamp)
- Code 39
- Reflection intensity: 85% min. for white and 5% max. for black
- Minimum narrow bar width: 1.4 mm min. (55.1 mils min.)
• The bar code reading procedure may differ depending upon the application
used, so follow the application's manual.
2
Chapter 1. Quick Guide
• Before reading bar codes, clean those labels if stained.
• Avoid using the BHT in direct sunlight. The BHT might fail to read correctly.
• To read bar codes on curved surfaces, apply the BHT to the target bar code so that the
code comes to the center of the scanning range indicated by the laser beam.
• When you pull the bar-code reading window away from bar codes, the actual
scanning range will become narrower than the range covered by the laser beam.
• Do not use the BHT in the vicinity of personal or amateur radio equipment. The
BHT may malfunction.
• Do not use the BHT near a magnetic body (e.g., equipment that generates a
magnetic field). Doing so will deflect the optical axis of the laser light, resulting
in scanning failure or machine failure.
• If the BHT has been stored in a hot (50˚C to 60˚C, 122˚F to 140˚F) and humid
place, allow it to sit at room temperature and humidity for at least one day before
use. Using the BHT with its inside being hot will fail to scan or result in a
machine failure.

1.5 Transferring Data
■ Using radio link (BHT-7500S/7500W only)
Using radio waves, the BHT-7500S/7500W may transfer data to an access point in a
spread-spectrum communications system.
If there are too many communications errors, first make sure that the BHT points
directly at an access point because the 2.4-GHz band requires a more or less
straight line path.
Host computer
Access point
Built-in antenna
For data transfer using radio link, it is necessary to configure a wireless local area
network (wireless LAN) connecting the BHT-7500S/7500W and access points.
7
■ Using infrared link
Using infrared rays, the BHT may transfer data directly to the host computer equipped
with an IrDA interface port and other IrDA-compliant devices.
• Make sure that there is no obstruction in the light path between the BHT and any
target stations. In infrared communication, you need to keep the BHT and any
target stations within the effective infrared radiation range, usually 10 to 80 cm
(3.94 to 31.50").
• Shield the IrDA interface from direct sunlight, intense overhead lighting (inverter-driven fluorescent lighting, in particular), and other potential sources of
infrared radiation. Sources to watch out for include remote control units for
television sets and the like.

■ 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 computer.)
■ 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 download 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 depending 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

resulting in a fire or bodily injury.
• Do not carry or store the battery cartridge together with metallic ball-point pens, necklaces,
coins, hairpins, etc.
Doing so could short-circuit the terminal pins,
causing the batteries to rupture or the battery
fluid to leak, resulting in a fire or bodily injury.
• Avoid dropping the battery cartridge or letting
it undergo any shock or impact.
Doing so could cause the batteries to break,
generate heat, rupture or burn.
• Never charge the rechargeable battery cartridge
where any inflammable gases may be emitted;
doing so could cause fire.
CAUTION
• Do not use batteries or power sources other
than the specified ones; doing so could generate heat or cause malfunction.
17
• Never charge the dry battery cartridge.
• The BHT has an integrated backup power source which backs up the memory and
calendar clock in the BHT when no battery cartridge is loaded or the voltage level
of the battery cartridge drops below the specified level. The backup power source
is automatically charged by the battery cartridge.
When you first load the battery cartridge after purchase or you load it after leaving
the BHT unused for a long time, do not remove the battery cartridge for 10
minutes or more after that loading. This is for charging the memory backup
source integrated in the BHT.
• Be sure to turn the BHT off before battery replacement. Replace the battery
cartridge quickly. Load a charged battery cartridge within 3 minutes from the
removal of the cartridge to avoid data loss.
After battery replacement, turn the BHT on and check its operation.
• If you leave the BHT with no battery cartridge loaded for a long time, the memory
contents will no longer be backed up so that the message "Contact your administrator. Note the error number. (XXXX)" or "Set the current date and time." may
appear on the LCD.
If you will not be using the BHT for a long time, follow the instructions given in
Subsection 2.3.6, "Battery Replacement Notes."
• When disposing of the battery cartridge, cover the terminal pins with vinyl tape to
prevent short-circuit.
• Avoid storing the rechargeable battery cartridge in a hot place. The battery
capacity may be decreased.
• Do not touch the charge terminals of the rechargeable battery cartridge by hand or
stain those terminals. Doing so could result in a charging failure.
■ Battery Voltage Level on the Status Indicator Line
The battery voltage level is always displayed on the status indicator line.

2.3.6 Battery Replacement Notes
■ When is battery replacement needed?
If the "Charge the battery!" or "Replace the batteries!" appears on the LCD, replace the
rechargeable battery cartridge with a fully charged one or replace the dry cells with
new ones, respectively.
If you leave the BHT without replacing the rechargeable battery cartridge or dry cells,
the integrated calendar clock or data will no longer be backed up so that the calendar
clock will stop or the message "Contact your administrator. Note the error number.
(XXXX)" will appear on the LCD.
Be sure to turn the BHT off before battery replacement.
Replace the battery cartridge quickly. Load a charged battery cartridge or new dry
cells within 3 minutes after the removal to avoid data loss.
After battery replacement, turn the BHT on and check its operation.
■ If you will use the BHT more than one time per month:
Keep the battery cartridge loaded in the BHT.
■ If you will not be using the BHT for more than one month:

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.
DECODE LEVEL
You may set the decode level. Decreasing the level value increases the bar-code
reading efficiency, but the BHT might misread low-quality bar codes (split or stained).
To the contrary, increasing the level value decreases the bar-code reading efficiency,
but it will diminish the possibility of misreading.
The setting range of the level value is from 1 to 9 and the default is 4.
58
Chapter 2. Getting Started the BHT and System Mode
Minimum number of digits to be read for ITF, STF, or Codabar (MINIMUM
DIGITS)
You may set the minimum number of digits to be read for ITF, STF, and Codabar.
Setting a small number of digits increases the frequency of digit-missing reading or
misreading depending upon how to scan bar codes or the quality of bar codes. On the
other hand, setting a large number will diminish the possibility of those errors.
The setting range is from 2 to 20 for ITF, from 1 to 20 for STF, and from 3 to 20 for
Codabar. The default is 4 for ITF and Codabar, and 2 for STF.

■ TYPE 1
After sending an echo request, PING will wait for the period specified by INTERVAL
and then send an echo request again. For TYPE 1, the relationship between the
INTERVAL and TIMEOUT should be "INTERVAL ≥ TIMEOUT."

3.1 Spread-Spectrum Communication
(BHT-7500S/7500W only)
3.1.1 Notes for Wireless Operations
• If there are too many communications errors, first make sure that the BHT points
directly at an access point because the 2.4-GHz band requires a more or less
straight line path. Note also that the low-power radio waves have trouble passing
through human bodies and other obstacles along that path.
• The radio link will not operate properly in the vicinity of microwave ovens, industrial
heaters, high-frequency medical equipment, and other sources of radio waves in
the 2.4-GHz band.
• Electromagnetic noise from personal computers, refrigerators, and other home
appliances can also interfere with link operation.
• Environmental factors that can also interfere with link operation include large
metallic objects, metallic dust, or metallic walls in the vicinity of the path and
vibration at either end.
To System Designers:
• Before developing the application, make sure that the intended environment is free
of the interference factors above and thus actually capable of supporting link
operation.
• Assume that there will be communications failures requiring robust retry
capabilities in the software.
3.1.2 RF-Related Parameters
Programs written in BHT-BASIC control wireless communication with commands between the BHT terminals and access points which are connected each other by a
wireless LAN.
BHT-7500S
For the setting procedure of RF-related parameters, refer to Subsection 2.5.3, "[ 8 ] RF
Menu BHT-7500S."
■ Domains
It is necessary to group a wireless LAN into domains and assign them with unique
domain names. A domain name should be included in the IDs of access points.
You may roam between access points during wireless communication if those access
points are within wireless networks having a same domain name.
For the setting procedure of domain names, refer to Subsection 2.5.3, [ 8 ] RF Menu.
124
Chapter 3. Communications Operations of the BHT
■ Security IDs
For assuring higher security, set security IDs to the BHTs. Those IDs should match
those of the access points.
Usually, use a same security ID for a company or a department (or section).
For the setting procedure of security IDs, refer to Subsection 2.5.3, [ 8 ] RF Menu.
BHT-7500W
For the setting procedure of RF-related parameters, refer to Subsection 2.5.3, "[ 8 ] RF
Menu BHT-7500W."
■ Client Name
This is a BHT name to be used on the network.
■ Service Set ID (SSID)
SSID is an ID to be used on the communications network. The BHT is able to
communicate with devices having the same SSID. The SSID of the BHT should be the
same as that of the access point you want to use.
■ POWER SAVE
You may place the wireless module built in the BHT in the energy saving mode. If this
mode is set to "OFF," the service period of the BHT may be shortened. If it is set to ON,
the BHT may take more time to wake up for link operation or send response messages.
■ WEP (Wired Equivalent Privacy)
When WEP is ON, messages to be sent/received over the wireless LAN will be encrypted.
The WEP KEY uses 40-bit (10-digit hexadecimal) or 128-bit (26-digit hexadecimal)
encryption word.
The BHT is able to definitely communicate with the access points having the same
WEP KEY.
■ WEP KEY
You can set four types of encryption keys (WEP KEY1 through WEP KEY4). If you
enable WEP, choose any one of WEP KEY1 through WEP KEY4 as TRANSMIT KEY.
■ AUTHENTICATE
This may set up the authentication system to be applied when WEP is enabled. You
can use either one of the two KEYs—OPEN and SHARED KEY to disable and enable the
authentication, respectively. If WEP is disabled, choose OPEN so that communication
is no longer possible. If WEP is enabled, choose SHARED KEY to enable wireless
communications.
■ TRANSMIT KEY
You need to use the TRANSMIT KEY in order to choose and activate any one of the
WEP KEY1 through WEP KEY4 already defined.
125
3.2 Infrared Communication
The BHT has an integrated infrared (IR) communications device which enables wireless transfer of programs and data between the BHT and the host computer and
between the BHTs, 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 may 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 IR transfer fails, bring the BHT closer to the target station or change the IR port
angle, and try again.
The BHT's IR communications device is IrDA-compliant. IrDA stands for Infrared Data
Association, which has defined hardware (IrDA Serial Infrared Physical Layer Link) and
communications protocols for IR communications.
The BHT's physical layer complies with the IrDA1.0, with a maximum transfer distance
of 0.8 m and maximum transmission rate of 115.2 kbits per second.
The BHT adopts the exclusive BHT-Ir protocol which allows you to develop user
programs for IR communications in BHT-BASIC, as can be done with conventional wire
communications.

3.3 RS-232C Interface Specifications
[ 1 ] Interface Connector and Pin Assignment
The BHT 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 to a host computer (or another BHT) directly without any routing
through the CU-7000.

otherwise, the service life of the plug will shorten. To connect the BHT to a host
computer having no IR port (or another BHT) frequently, use the CU-7000.
• 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.

None
■ 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 (31.5 in.) with the IR beam
within a 10˚ angle of divergence.
■ Switching Time between Sending and Receiving on Optical Interface
The optical interface should satisfy the following requirements in switching between sending and receiving:
(1)
Within 10 ms from completion of sending, the optical interface should become
ready to receive.
(2)
After 10 ms or more from completion of receiving, the optical interface should
start sending.
129
■ 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 is JIS 7- or 8-bit code. The transmission
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.
LSB

MSB
0

■ 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 significant bit) as shown below.

Refer to Chapter 2, Subsection 2.5.3, [4.5], "Setting the communications environments."
In BHT-BASIC
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.
OPEN "COM: ... "
Opens the interface port selected in System Mode.
OPEN "COM1: ... "
Opens the optical interface port for data transmission,
irrespective of the setting in System Mode.
OPEN "COM2: ... "
Opens the direct-connect interface port for data transmission, 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.
131
3.5 Communications Protocols
The BHT supports both the BHT-protocol and the BHT-Ir protocol for file transmission.
3.5.1 BHT-protocol
[ 1 ] Overview
The BHT-protocol is the communications procedure used to transmit files between the
BHT and a host (or between the BHTs). 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.
For details about the transmission control sequences and horizontal parity checking,
refer to Appendix B, B.1, "BHT-protocol."
132
Chapter 3. Communications Operations of the BHT
[ 2 ] Control Characters
The control characters are classified into two groups: transmission control characters
and text control characters.

■ Transparency
The BHT 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.
133
(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

You may designate values of headers and a terminator with the protocol functions in
BHT-BASIC. If you designate none of them in a user program, the BHT may apply
those as listed above. Refer to the "BHT-BASIC Programmer's Manual."
134
Chapter 3. Communications Operations of the BHT
[ 3 ] Basic Format of Transmission Messages
Basically, the BHT 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.

3.5.2 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 and a host (or between the BHTs). 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.
For details about the transmission control sequences and CRC, refer to Appendix B,
B.2, "BHT-Ir protocol."
138
Chapter 3. Communications Operations of the BHT
[ 2 ] Control Characters
The control characters are classified into two groups: transmission control characters
and text control characters.

■ Transparency
The BHT 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.
139

Text control characters
The text control characters are used to format transmission texts.

In the BHT-Ir protocol, you cannot change the values of the headers and terminator
with the protocol functions in BHT-BASIC.
140
Chapter 3. Communications Operations of the BHT
[ 3 ] Basic Format of Transmission Messages
Basically, the BHT 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, (2). 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 Appendix B, B.2, "BHT-Ir protocol, " [ 3 ].
You can use the control characters for expressing IDs, serial numbers, or text data.

5.5 Charging the Rechargeable Battery Cartridge (using the CU-7001)
You may charge a rechargeable battery cartridge loaded in the BHT.
Service Life of Rechargeable Battery Cartridge:
Lithium-ion batteries used in the rechargeable 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 deterioration 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. 300 cycles of charging and
discharging operation.

Data transmission may accidentally involve various types of errors. The BHT-protocol
is designed to recover from those errors as frequently as possible.
What follows is the BHT-protocol for phases 1 through 3.
Phase 1: Establishment of Data Link
■ Normal phase 1
The sending station transmits an ENQ to the receiving station. Upon receipt of an
ACK from the receiving station, the sending station shifts to phase 2.
ENQ
Sending station
Receiving station
ACK
To phase 2.
■ Phase 1 with iterated ENQ transmission due to no response or invalid
response
If the sending station receives no response or any invalid response from the
receiving station in response to an ENQ sent, it iterates sending of an ENQ at threesecond intervals up to 10 times.
If the sending station receives an ACK before sending an ENQ ten times, it shifts to
phase 2.
Sending

You may modify the number of ENQ iterations for the sending station. The
default is 10 times at three-second intervals. For details, refer to the SET
PROTOCOL screen in System Mode (pp. 62 and 64) and the XFILE statement
given in "BHT-BASIC Programmer's Manual."
176
Appendices
■ Abnormal termination of phase 1 (Abort of phase 1)
If the sending station receives no ACK from the receiving station after sending an
ENQ 10 times in succession, it sends an EOT to the receiving station after three
seconds from the 10th ENQ to terminate the message transmission abnormally.

The receiving station's default timeout is 30 seconds. You may modify the
timeout length on the SET PROTOCOL screen in System Mode (pp. 62 and 64)
or by using the XFILE statement (refer to the "BHT-BASIC Programmer's
Manual").
177
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 an ACK from the receiving station, it sends a
transmission block containing the data texts as shown below. Upon receipt of an
ACK 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.

Appendices
■ Phase 2 with NAK
If the sending station receives a NAK from the receiving station in response to a
transmission block containing text data m, it sends that transmission block again
immediately as shown below.
If the sending station receives an ACK before receiving a NAK 10 times in succession, it continues the subsequent message transmission.

[ 2 ] Aborting Data Transmission
Pressing the C key aborts data transmission.
If the C key is pressed during downloading, the BHT transmits an EOT and aborts
the file transmission.
If it is pressed during uploading, the BHT transmits the current transmission block
followed by EOT and then aborts the file transmission.
183
[ 3 ] BCC for Horizontal Parity Checking
To check whether data has been transmitted accurately, the BHT supports horizontal
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,
refer to the "BHT-BASIC Programmer's Manual.")

Data transmission may accidentally involve various types of errors. The BHT-Ir protocol 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.

You may modify the number of iterations of a sequence of DLE ENQ and IDm
for the sending station. The default is 60 times at 0.5-second intervals. For
details, refer to the SET PROTOCOL screen in System Mode (pp. 62 and 64)
and the XFILE statement given in "BHT-BASIC Programmer's Manual."

■ 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 transmission abnormally.

The receiving station's default timeout is 30 seconds. You may modify the
timeout length on the SET PROTOCOL screen in System Mode (pp. 62 and 64)
or by using the XFILE statement (refer to the "BHT-BASIC Programmer's
Manual").
187
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 memory
If the receiving BHT requires the flash memory 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.

[ 2 ] Aborting Data Transmission
Pressing the C key aborts data transmission.
If the C key is pressed during downloading, the BHT transmits a sequence of DLE

If it is pressed during uploading, the BHT transmits the current transmission block
followed by a sequence of DLE EOT and IDs and then aborts the file transmission.

Appendices
[ 3 ] 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 LSB of the first byte to the MSB 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.

[ 4 ] ID
ID is a 2-digit hexadecimal and designated in 0000h through FFFFh in (2 bytes). 0000h
is assigned to the host computer. Any of 0001h through FFFFh is assigned to the BHT
as follows.
• The system sets an ID when the BHT is initialized.
• You may set an arbitrary ID in System Mode or by using the OUT statement in
BHT-BASIC.
