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:

• CU-5000:

Allows you to edit, manage and download programs and data, as well as downloading extension programs.

Exchanges programs and data with the BHT-5000 optically 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.)

■ 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 BHT-

5000 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

XFILE

statement in BHT-BASIC 3.0.

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:."

10


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 BHT-

BASIC 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).

WARNING

CAUTION

• 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.


• 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:

- For the dry 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.

Replace the dry batteries in the cartridge with new ones.

Charge the battery !

Replace the batteries

(When the Ni-MH battery cartridge is loaded)

(When the dry battery cartridge is loaded)

■ Charging the Ni-MH Battery Cartridge

You may charge the Ni-MH battery cartridge with the optical communications unit CU-

5001 or the quick charger C-500 (option). For the charging procedure with the CU-

5001, refer to Chapter 5. For the charging procedure with the C-500, refer to the "C-500

User's Manual."

WARNING

Only use the dedicated charger (CU-5001 or

C-500) for charging the Ni-MH battery cartridge.

CAUTION

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

2 Touch Read : Switches to the touch scanning

(ON) or long-range scanning

(OFF).

3 Decode Level : Sets the decode level.

Select a desired item by using the numerical keys or * and * keys, and then select a desired setting by using * and * keys.

To increase the decode level, press * key; to decrease it, press * key.

Press the ENT key.


Black-and-white inverted label reading function (Invert)

This function makes it possible to read white bars on a black background.

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.

3.2 Basic Communications Specifications and Parameters

JIS 7-bit/8-bit codes

LSB (Least significant bit) first

ACK/NAK response

Even, odd, or none

Non-transparent mode

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

1 0 0 0 0 0 1

MSB

0 0

Start bit

Stop bit

Parity 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.

LSB MSB b0 b1 b2 b3 b4 b5 b6

(For 7-bit data)

LSB b0 b1 b2 b3 b4 b5 b6

MSB b7

■

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

Enabled (ON)

Disabled (OFF)

BHT-5000 Operation

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.

The BHT-5000 does not check the CS signal when starting data transmission.

The RS signal is always ON.

NOTE

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

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

For the RS/CS control in user programs written in BHT-BASIC 3.0, refer to the "BHT-

BASIC 3.0 Programmer's Manual."

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

* 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:

...

"

OPEN "COM1:

...

"

Opens the interface port selected in System Mode.

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 OPEN "COM:" statement, the XFILE statement transmits a designated file.

78


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.

■

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


(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.

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.

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.

3.3.5 Aborting Data Transmission

Pressing C key aborts data transmission.

If C key is pressed during downloading, the BHT-5000 transmits an EOT and aborts the file transmission.

If it is pressed during uploading, the BHT-5000 completes the block transmission and then aborts the file transmission.

91

3.3.6 BCC for Horizontal Parity Checking

To check whether data has been transmitted accurately, the BHT-5000 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

3.0, refer to the "BHT-BASIC 3.0 Programmer's Manual.")

SION. The FILE NAME should be 1 to

8 characters long. The EXTENSION should be other than .PD3, .FN3, and

.EX3, and it may be omitted (together with a period).

The number of data texts should be 0 to

32767. If it is less than 5 digits, the upper blank bytes will be filled with zeros (0).

Every data field should be 1 to 99 digits long. If it is less than 2 digits, the upper blank byte will be filled with zero (0).

The number of fields should be 1 to 16. If it is less than 2 digits, the upper blank byte will be filled with zero (0).

If the data file name is less than 12 characters in length, the lower blank bytes will be filled with space characters.

Every data field should be

1 to 99 digits long.

If a data field is less than the maximum digits in length, the lower blank bytes will be filled with space characters.

NOTE

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 transferring data files, the BHT-protocol automatically prefixes a character count byte in binary format to each data field.)

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.

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

You may charge Ni-MH battery cartridges either loaded in the BHT-5000 or all by themselves.

NOTE

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 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. 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 will become abnormally 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-5001 or C-500 for fully discharging and recharging.

5.5.1 Ni-MH Battery Cartridge Loaded in the BHT-

5000

(1) Turn on the CU-5001.

(2) Place the BHT-5000 loaded with a Ni-MH battery cartridge onto the CU-5001.

The CU-5001 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.
