2.1 BHT-5000 System Configuration

As shown in the system configuration below, it is necessary to prepare not only the
BHT-5000 Bar Code Handy Terminal (which reads bar codes and accepts keypad entry)
but also the following hardware:

• Host computer: Allows you to edit, manage and download programs

and data, as well as downloading extension programs.

• CU-5000: Exchanges programs and data with the BHT-5000 op-

tically and with the host computer via the RS-232C
interface.

• RS-232C interface cable: Connects the CU-5000 and the host computer.

The basic software required for operating the BHT-5000 is "System Program" which is
resident in the flash ROM.

Optional software includes the BHT-BASIC 3.0 Extension Library, BHT-BASIC 3.0 Com­piler, and Transfer Utility. (Each software is provided in a floppy disk.)

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 BHT­5000 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 func­tion. 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.

9

Flash ROM and RAM

A flash ROM and RAM are mounted on the BHT-5000.

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-5000. 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 battery 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

You cannot write data scanned with the BHT, 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:."

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

Software Structure

System Program and JIS Level 1 & Level 2 fonts are resident in the system area of the
flash ROM.

To use extension programs and user programs, you should download the program
files into the user area (of the flash ROM or RAM).

Prior to executing user programs, it is necessary to prepare a data file. The data files
will be stored in the user area (of the flash ROM or RAM).

■ System Programs

The system programs include the following three sets of programs:

Drivers

Drivers is a set of programs that directly controls the BHT-5000 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 BHT­BASIC 3.0.

System Mode

System Mode is a system program exclusively designed for the effective use of user
programs in the BHT-5000. It sets up the execution environments for those programs;
e.g., it prepares downloading/uploading conditions, sets the calendar clock, and tests
the BHT-5000 components including the LCD, beeper, and keypad. Shown below is the
System Mode menu (SYSTEM MENU).

SYSTEM MENU
1:Execute Program
2:Download
3:Upload
4:Set System
5:Test
6:Version

11

■ JIS Level 1 and Level 2 Fonts

These are font data required for displaying Kanji characters on the LCD.

The BHT-5000 has no Kanji ROM, so it stores these Kanji fonts in the flash ROM.

■ Extension Programs

These programs extend the system programs by adding new functions which cannot
be handled by the ordinary system.

To download the desired extension program in the BHT-BASIC Extension Library, use
Transfer Utility (option).

■ 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-5000, use
Transfer Utility (option).

2.3 Preparation

2.3.1 Setting-up 1: Loading the Battery Cartridge

Before starting the BHT-5000, be sure to load the battery cartridge (sold separately)
according to the steps below.

(1) For the Ni-MH battery cartridge: Charge the battery cartridge, referring to Section

5.5, "Charging the Ni-MH Battery Cartridge (using the CU-5001)."

For the dry battery cartridge: Load two LR6 batteries into the cartridge, referring
to the "User's Manual of Dry Battery Cartridge" contained in the battery cartridge
package.

(2) Turn the BHT-5000 upside down.

(3) Push the battery cartridge into the BHT-5000 until it clicks into place. (To remove

the battery cartridge, press the release button.)

Battery cartridge

WARNING

CAUTION

Release button

• Never disassemble or heat the battery cartridge,
nor put it into fire or water; doing so could
cause battery-rupture or leakage of battery fluid,
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 Ni-MH battery cartridge where
any inflammable gases may be emitted; doing
so could cause fire.

• Do not use batteries or power sources other
than the specified ones; doing so could gener­ate heat or cause malfunction.

NOTE

NOTE

NOTE

NOTE

REFERENCE

When you first load the battery cartridge after purchase or you load it after leaving
the BHT-5000 unused for a long time, do not remove the battery cartridge within 24
hours after that loading.

Do not leave the BHT-5000 with no 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-5000 integrates a rechargeable lithium battery which backs up the
memory in the BHT-5000 when no battery cartridge is loaded or the voltage
level of the battery cartridge drops below the specified level. The lithium
battery is automatically charged by the battery cartridge.

17

■ Checking the Battery Voltage Level

Pressing ENT key while holding down SF key displays the current voltage level of the
battery cartridge as a bar indicator on the LCD. (Releasing those keys will erase the
indication.)

For details, refer to Subsection 2.3.3, "Adjusting the LCD Contrast & Beeper Volume,
and Displaying the Battery Voltage Level."

■ Low Battery Indication

If the battery voltage level drops below the specified level while the BHT-5000 is in
operation, the BHT-5000 displays the following message on the LCD, beeps five times,
and turns itself off automatically.

- For the Ni-MH battery cartridge: Charge the battery cartridge (see ■ Charging the

Ni-MH Battery Cartridge below) or replace the
current battery cartridge with a fully charged
one.

- For the dry battery cartridge: Replace the dry batteries in the cartridge with
new ones.

Replace the batteriesCharge the battery !

(When the Ni-MH battery
cartridge is loaded)

(When the dry battery

■ Charging the Ni-MH Battery Cartridge

You may charge the Ni-MH battery cartridge with the optical communications unit CU­5001 or the quick charger C-500 (option). For the charging procedure with the CU­5001, refer to Chapter 5. For the charging procedure with the C-500, refer to the "C-500
User's Manual."

WARNING

CAUTION

Only use the dedicated charger (CU-5001 or
C-500) for charging the Ni-MH battery cartridge.

Never charge a set or damp Ni-MH battery car­tridge.

Doing so could cause the batteries to break, gen­erate heat, rupture or burn.

NOTE

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. (The BHT-5000 can read bar codes at a maximum distance of 20 cm (7.9") from
the bar-code reading window.)

If "Touch Read" is set to ON, the reading speed increases in touch scanning. In long­range 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-5000 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

You may set the recognition level. Decreasing the level value increases the bar-code
reading efficiency, but the BHT-5000 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 default "3" is
recommended.

3.1.2 For BHT-5000

[ 1 ] Interface Connector and Pin Assignment

The BHT-5000 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-5000 to a host computer (or another BHT-5000) directly without
any routing through the CU-5000.

3.2 Basic Communications Specifica­tions and Parameters

3.2.1 Basic Communications Specifications

Listed below are the communications specifications when the BHT-5000 transacts data
with a host computer through the CU-5000 (optical interface) or direct-connect inter­face cable.

Synchronization Start-stop

Transmission Speed 300, 600, 1200, 2400, 4800, 9600, 19200, or 38400 bps

Transmission Code JIS 7-bit/8-bit codes

Transmission Bit Order LSB (Least significant bit) first

Response Method ACK/NAK response

Vertical Parity Even, odd, or none

Transparency Non-transparent mode

RS/CS Control Enabled or disabled

■ 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).

75

■ 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-5000 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

10 0 000100

Start bit

Stop 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 signifi­cant bit) as shown below.

■ RS/CS Control

Depending upon whether the RS/CS control is enabled or disabled in System
Mode, the BHT-5000 operation will differ as follows:

RS/CS Control BHT-5000 Operation

Enabled (ON) If the CS signal is ON when the BHT-5000 is ready to send, the

BHT-5000 will send data. If it is OFF, the BHT-5000 will wait for
the CS signal to go ON until the timeout occurs.

When the BHT-5000 becomes ready to receive data, it will turn
the RS signal ON.

Disabled (OFF) The BHT-5000 does not check the CS signal when starting data

transmission.

The RS signal is always ON.

NOTE

For the RS/CS control in user programs written in BHT-BASIC 3.0, refer to the "BHT­BASIC 3.0 Programmer's Manual."

The timeout length is programmable in user programs written in BHT-BASIC

3.0. If not designated in programming, it is three seconds.

77

3.2.2 Communications Parameters

In System Mode and user programs written in BHT-BASIC 3.0, you may set the
communications parameters listed below.

Communications Port Optical interface or direct-connect interface

Transmission Speed 300*, 600*, 1200, 2400, 4800, 9600, 19200, or 38400 bps

Character Length 7 or 8 bits

Vertical Parity Odd, even, or none

Stop Bits 1 or 2 bits

RS/CS Control Enabled or disabled

* The 300 bps and 600 bps are not available in System

Mode.

In System Mode

Refer to Chapter 2, Subsection 2.4.3, "Detailed Description of the Functions in System
Mode," [ 4.5 ] Setting the communications parameters and interface port.

In BHT-BASIC 3.0

To set the transmission speed, character length, and the number of stop bits, 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-5000, irrespective of the setting
in System Mode.

OPEN "COM2: ... " Opens the direct-connect interface port for direct 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
statement transmits a designated file.

OPEN "COM:" statement, the XFILE

3.3 BHT-Protocol

3.3.1 Overview

The BHT-protocol is the communications procedure used to transmit files between the
BHT-5000 and a host (or between the BHT-5000s). 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.

79

3.3.2 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-5000 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.

80

Chapter 3. Communications Operations of BHT-5000

(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 by the protocol functions in BHT-BASIC

3.0. If you designate none of them in a user program, the BHT-5000 may apply those

as listed above. Refer to the "BHT-BASIC 3.0 Programmer's Manual."

81

3.3.3 Basic Format of Transmission Messages

Basically, the BHT-5000 transmits data as a unit 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, and 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
Subsection 3.3.2. The serial number is added to every data text in order to identify
those texts. For BCC, refer to Subsection 3.3.6.

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.

■ Phase 1 with 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.
