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 indicate the scanning range and turns on the illumination LED to scan the bar code. Keep the BHT in a position where the bar code lies within the scanning range indicated by the laser light (marker).

When the BHT has read the bar code successfully, the indicator LED will illuminate in green.

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.)

• The laser light indicates the scanning range as a guide. The indicated scanning range will deviate a little bit from the actual one. Keep the BHT so that the laser light comes to almost the center of the bar code height.

• The BHT can read bar codes at a maximum distance of 40 cm (15.7")** from the bar-code reading window. (**For details about the scanning conditions, refer to the Appendix A.)

NOTE

TIP

• 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 the bar codes, the actual scanning range will become narrower than the range covered by the laser beam.

• The light intensity of the laser light or illumination LED will vary depending upon the scanning conditions and variation of their elements.

1.4 Using the Keypad

■ Entering Numerical Data

To enter numerical data, e.g., the quantity of goods, use the ten numerical keys and the ENT key.

For example, to enter the number "120," press the 1 , 2 and 0 keys and then press the ENT key.

26-key pad: If you key in any wrong value, press the C key or BS key and then enter the correct one.

32-key pad: If you key in any wrong value, press the C key or SF + C keys and then enter the correct one.

■ Selecting Tasks

If the LCD shows the selection items (xxx) prefixed by numerals (e.g., 1: xxx, 2: xxx), use the numerical keys to select a desired item and press the ENT key to execute.

If a YES/NO screen (e.g., 1: YES, 2: NO) appears, press the 1 key for YES response and

2 key for NO response.

■ Entering Alphabetic Characters

The BHT-7000 supports the alphabet input function which allows you to enter alphabetic characters, space, and symbols from the keypad during execution of a user program. For the alphabet input procedure, refer to the "BHT-BASIC Programmer's

Manual."

1.5 Communicating via the Optical Interface

■ Optical Communications with the BHT-7000

The BHT-7000 communicates using an IR beam, so make sure that there is no obstruction in the light path between the BHT-7000 and any target stations.

In the IrDA communications mode, you need to keep the BHT-7000 and any target stations within the effective light emission range, usually 10 to 80 cm (3.94 to 31.50'').

■ Communicating with the CU-7000

The optional CU-7000 is an IrDA-compliant communications unit. For optical communications, put the BHT-7000 directly on the CU-7000 as shown below.

■ Communicating with other IrDA-compliant equipment

You can also have the BHT-7000 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-7000 fails, bring it closer to the target station or change the IR port angle, and try again.

NOTE

NOTE

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 optical interface ports of the BHT-

7000 and IrDA-compliant equipment, including the CU-7000.

Do not use any TV remote control in the vicinity of the IR communications system.

Doing so may interfere with the communications.

■ 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-7000 optically, and with the host computer via the

RS-232C interface cable.

You may directly connect two BHT-7000s 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-7000 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-7000 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-

7000 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-7000. 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-7000 by using Ir-Transfer Utility C/Ir-Transfer Utility E/Transfer Utility.

■ Ir-Transfer Utility C (option)

2.2 Infrared Communications

The BHT-7000 has an integrated infrared (IR) communications device which enables wireless transfer of programs and data between the BHT-7000 and the host computer and between the BHT-7000s, instead of the conventional wire transfer.

Host computer

BHT-7000

BHT-7000

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-7000'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.

13

The BHT-7000'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-7000 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.

NOTE

NOTE

NOTE

Never charge the dry battery cartridge.

The BHT-7000 has an integrated backup power source which backs up the memory and calendar clock in the BHT-7000 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-7000 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-7000.

Be sure to power off the BHT-7000 before battery replacement. Replace the battery cartridge quickly. Load a charged battery cartridge within 3 minutes from the removal of the cartridge in order to avoid data loss.

After battery replacement, power on the BHT-7000 and check its operation.

If you leave the BHT-7000 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-7000 for a long time, follow the instructions given in Subsection 2.4.4, "Battery Replacement Notes."

When disposing of the battery cartridge, cover the terminal pins with vinyl tape to prevent short-circuit.

Avoid storing the battery cartridge in a hot place. The battery capacity may be decreased.

Do not touch the charge terminals of the battery cartridge by hand or stain those terminals. Doing so could result in a charging failure.

■ Checking the Battery Voltage Level

The battery voltage level is always displayed on the status indicator line.

(For details, refer to Subsection 2.4.3, "Adjusting the LCD Contrast & Beeper Volume,

Switching the Beeper & Vibrator, and Checking the Battery Voltage Level," [ 2 ].)

19

■ Low Battery Indication

Low battery indication—Level 1

If the battery output voltage drops below a specified lower level limit while the BHT-

7000 is in operation, the BHT-7000 displays the following level 1 message for approx. 2 seconds and beeps three times. After that, it will resume previous regular operation.

Battery voltage

has lowered.

The service life of the battery cartridge will expire soon. If the BHT-7000 is driven by the lithium-ion battery cartridge, recharge or replace it; if it is driven by the dry battery cartridge, replace the dry batteries.

Low battery indication—Level 2

If you continue to use the BHT-7000 without recharge or battery replacement after the level 1 message appears, the BHT-7000 displays the following level 2 message, beeps five times, and then turns itself off.

(When driven by the lithium-ion battery cartridge)

Charge the

battery!

(When driven by the dry battery cartridge)

Replace the

batteries!

If the BHT-7000 is driven by the lithium-ion battery cartridge, recharge or replace it; if it is driven by the dry battery cartridge, replace the dry batteries.

20


NOTE • Before battery replacement, be sure to power the BHT-7000 off. Within three minutes from the removal of the battery cartridge, load the battery cartridge to avoid data loss. After battery replacement, power the BHT-7000 on and check its operation.

• When replacing dry batteries, always replace both of them with new alkaline manganese batteries (LR6).

• You may charge the lithium-ion battery cartridge with the optional CU-7000 communications unit or optional C-700/C-750 charger. For the charging procedure using the CU-7000, refer to Chapter 5. For that using the C-700/C-750, refer to the "C-700 User's Manual"/"C-750 User's Manual."

• If the "Charge the battery!" or "Replace the batteries!" message appears after the BHT-7000 undergoes any shock or impact, turn the power off and on and then check the battery output level. The battery may not have run out.

WARNING Only use the dedicated charger (CU-7000, C-700, or C-750) for charging the lithium-ion battery cartridge.

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.

DECODE LEVEL

You may set the decode level. Decreasing the level value increases the bar-code reading efficiency, but the BHT-7000 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 disminish the possibility of misreading.

The setting range of the level value is from 1 to 9 and the default is 4.



, ,

50


Minimum number of digits to be read for ITF, STF, or CODABAR (MINIMUM

DIGITS)

You may determine 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.

MARKER

You may select either of the following ON/OFF modes of a laser beam (marker) which indicates the scanning range:

0: Normal mode (in which the laser and illumination LED come on at the same time at the time of scanning)

1: OFF mode (in which no laser comes on)

TIP

Even if the MARKER is set to 0 (Normal mode), the marker will not come on when the read mode is set to the alternate switching mode or continuous reading mode.

If you define the M1 key as the backlight function on/off key, pressing the M1 key activates or deactivates the backlight function.

In user programs, a string data also can be assigned to these magic keys.

NOTE

The backlight function on/off key can be assigned only to any one of M1 through

M4 keys. The key defined more recently will act as the backlight function on/off key and one defined earlier will be ignored.

That is, if you define the M1 and M2 keys as the backlight function on/off key in this order, the M2 key will work as the backlight function on/off key and the M1 key's entry will be ignored.

3.1 RS-232C Interface Specifications

[ 1 ] Interface Connector and Pin Assignment

The BHT-7000 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-7000 to a host computer (or another BHT-7000) directly without any routing through the CU-7000.

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-7000 to a host computer having no IR port (or another BHT-7000) 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-7000.

JIS 7- or 8-bit codes

LSB (Least significant bit) first

Even, odd, or 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.

88


■

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-7000 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

■

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

7 or 8 bits

Odd, even, or none

1 or 2 bits

In System Mode

Refer to Chapter 2, Subsection 2.6.3, [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: ... "

OPEN "COM1: ... "

Opens the interface port selected in System Mode.

Opens the optical interface port for data transmission routing through the CU-7000, 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.

90


3.3 Communications Protocols

The BHT-7000 supports both the BHT-protocol and the BHT-Ir protocol for file transmission.

3.3.1 BHT-protocol

[ 1 ] Overview

The BHT-protocol is the communications procedure used to transmit files between the

BHT-7000 and a host (or between the BHT-7000s). 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."

91

[ 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-7000 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.

92


(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.


SOH 01h Start Of Heading

STX

ETX

02h

03h

Start Of Text

End Of Text

Function

Indicates the start of heading text (Phase

2).

Indicates the start of data text (Phase 2).

Indicates the end of data text (Phase 2).

You may designate headers and a terminator with the protocol functions in BHT-

BASIC. If you designate none of them in a user program, the BHT-7000 may apply those as listed above. Refer to the "BHT-BASIC Programmer's Manual."

93

[ 3 ] Basic Format of Transmission Messages

Basically, the BHT-7000 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.

94


[ 4 ] Text Format

Text should be formatted according to the standard of the BHT-protocol before transmission. Shown below are two types of the standard text formats for program files and data files.

■

Program Text Format

(1) Heading text

P R O G 1 .

P D 3 0 0 3 5 2

The program file name should be a maximum of 12 characters in length and it consists of FILE

NAME and .EXTENSION. The

FILE NAME should be 1 to 8 characters. The EXTENSION should be .PD3 (.FN3 and .EX3

may be available for future functional expansion).

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

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).

.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).

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 254 digits in length. If it is less than 2 digits, the upper blank byte will be filled with zero (0).

If a data field is 100 to 199 digits in length, @0 to I9 will be given; if it is 200 to

254 digits, P0 to U4 will be given.

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).

To transfer a data file containing a data field(s) of 100 digits or more, use the

Windows-based Transfer Utility. The MS-DOS–based Transfer Utility does not support transmission of data fields exceeding 99 digits.

(2) Data text

1 to 99 digits in length.

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

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.

96


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-7000 and a host (or between the BHT-7000s).

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."

97

Transparency

The BHT-7000 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.

98


(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.

In the BHT-Ir protocol, you cannot change the values of the headers and terminator with the protocol functions in BHT-BASIC.

99

[ 3 ] Basic Format of Transmission Messages

Basically, the BHT-7000 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.

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

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.

5.5 Charging the Lithium-ion Battery

Cartridge (using the CU-7001)

You may charge lithium-ion battery cartridges loaded in the BHT-7000.

Service Life of Lithium-ion Battery Cartridge:

Lithium-ion 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. 300 cycles of charging and discharging operation.

(1) Plug the AC adapter of the CU-7001 into the wall socket.

The POWER LED on the CU-7001 comes on.

(2) Place the BHT-7000 loaded with a battery cartridge onto the CU-7001.

The BHT-7000 turns on the indicator LED in red and starts charging. The charging time is approx. 4 hours.

Upon completion of charging, the indicator LED turns green.

(3) Take the BHT-7000 off the CU-7001.

BHT-7000

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.

Sending station

■

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.

134

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.

Manual").

135

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.

[ 2 ] Aborting Data Transmission

Pressing the C key aborts data transmission.

If the C key is pressed during downloading, the BHT-7000 transmits an EOT and aborts the file transmission.

If it is pressed during uploading, the BHT-7000 transmits the current transmission block followed by EOT and then aborts the file transmission.

141

[ 3 ] BCC for Horizontal Parity Checking

To check whether data has been transmitted accurately, the BHT-7000 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 response 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.

Manual").

145

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-7000 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.

[ 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 X

16

. Next, divide the polynomial by the generative polynomial X

16

+ X

15

+ X

2

+ 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-

7000 as follows.

• The system sets an ID when the BHT-7000 is initialized.

• You may set an arbitrary ID in System Mode or by using the OUT statement in

BHT-BASIC.
