Chapter 2. Getting Started the BHT-6000 and System Mode Chapter 2 Getting Started the BHT-6000 and System Mode This chapter summarizes the BHT-6000 system configuration and describes the operation including preparation and System Mode (which is required for the efficient use of application programs). 2.1 BHT-6000 System Configuration ............................................................................................................ 8 2.2 Infrared Communications .................................
2.1 BHT-6000 System Configuration The BHT-6000 barcode data collection system requires the following hardware as well as the BHT-6000 Bar Code Handy Terminal (which reads bar codes and accepts keypad entry) as illustrated below: • Host computer: Allows you to edit, manage and download programs and data, as well as downloading extension programs. For host computers without IrDA interface ports, the optional CU-6000 optical communications unit and RS-232C interface cable are available.
Chapter 2. Getting Started the BHT-6000 and System Mode ■ CU-6000 and RS-232C Interface Cable (option) The CU-6000 is an IrDA-compliant communications unit which is required when your host computer is not equipped with an IrDA interface port. The CU-6000 exchanges data and programs with the BHT-6000 optically, and with the host computer via the RS-232C interface cable.
■ Transfer Utility (option) Running on the host computer, this utility transfers files between the BHT-6000 and the host computer. It uses the BHT-protocol as a file transfer control procedure. (For the details about the BHT-protocol, refer to Chapter 3, Subsection 3.3.1.
Chapter 2. Getting Started the BHT-6000 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). Before the execution of user programs, you need to prepare a data file. The data files will be stored in the user area (of the flash ROM or RAM).
■ JIS Level 1 and Level 2 Font Files These files contain font data required for displaying Kanji characters on the LCD. The BHT-6000 has no Kanji ROM, so it stores Kanji fonts in the flash ROM. The BHT-6000 can display not only the Kanji characters in the conventional standardsize font (16 dots wide by 16 dots high) but also them in the small-size font (12 dots wide by 12 dots high) in application programs.
Chapter 2. Getting Started the BHT-6000 and System Mode 2.2 Infrared Communications The BHT-6000 has an integrated infrared (IR) communications device which enables wireless transfer of programs and data between the BHT-6000 and the host computer and between the BHT-6000s, instead of the conventional wire transfer.
2.3 Components and Functions • Reading confirmation LED Illuminates in green when the BHT has successfully read the bar codes. • M1 and M2 keys Press either of these keys to start bar-code reading. (The trigger switch function is assigned to both these keys by default.) • Connector cover Inside this cover is the direct-connect interface port. • Liquid crystal display (LCD) Shows the characters and graphic patterns.

Chapter 3. Communications Operations of BHT-6000 Chapter 3 Communications Operations of BHT-6000 This chapter describes the communications operations of the BHT-6000--the RS-232C interface specifications, the basic communications specifications, and the communications protocols--for data transmission with the host computer or other devices. 3.1 RS-232C Interface Specifications .........................................................................................................
3.1 RS-232C Interface Specifications [ 1 ] Interface Connector and Pin Assignment The BHT-6000 has a direct-connect interface port which is connectable to the 3-pole mini stereo plug (ø2.5 mm or 0.1") and supports a subset of the RS-232C interface as shown below. Using a direct-connect interface cable having the mini stereo plugs makes it possible to connect the BHT-6000 to a host computer (or another BHT-6000) directly without any routing through the CU-6000. SD RD SG 3-pole Mini Stereo Plug (ø2.
Chapter 3. Communications Operations of BHT-6000 [ 2 ] Interface Cable Connection Connect the BHT-6000 directly to a host computer, a modem, or a printer with a directconnect interface cable as illustrated below.
3.2 Basic Communications Specifications and Parameters 3.2.1 Basic Communications Specifications Listed below are the communications specifications when the BHT-6000 exchanges data with a host computer through the CU-6000 (optical interface) or direct-connect interface cable.
Chapter 3. Communications Operations of BHT-6000 ■ Transmission Code and Bit Order All characters should be coded to 7- or 8-bit code for data transmission. The standard data exchange code of the BHT-6000 is JIS 7- or 8-bit code. The 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.
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.
Chapter 3. Communications Operations of BHT-6000 3.3 Communications Protocols The BHT-6000 supports both the BHT-protocol and the BHT-Ir protocol for file transmission. 3.3.1 BHT-protocol [ 1 ] Overview The BHT-protocol is the communications procedure used to transmit files between the BHT-6000 and a host (or between the BHT-6000s). It adopts the response method using ACK/NAK codes.
[ 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).
Chapter 3. Communications Operations of BHT-6000 (2) Text control characters The text control characters are used to format transmission texts. In the BHT-protocol, they include the following headers and a terminator. Symbol Value Meaning Function SOH 01h Start Of Heading Indicates the start of heading text (Phase 2). STX 02h Start Of Text Indicates the start of data text (Phase 2). ETX 03h End Of Text Indicates the end of data text (Phase 2).
[ 3 ] Basic Format of Transmission Messages Basically, the BHT-6000 transmits data as units of a file. First, it transmits a heading text which includes the attribute information of a file (e.g., file name and the number of data texts) to be transmitted. Following the heading text, it transmits the data text in the file. A heading text and data text comprise a text. In actual text transmission, the text is divided into several blocks, then a header and terminator are added to each block.
Chapter 3. Communications Operations of BHT-6000 [ 4 ] Transmission Control Sequences Shown below is a typical message transmission sequence supported by the BHTprotocol. This sequence example does not include transmission errors or negative responses.
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.
Chapter 3. Communications Operations of BHT-6000 ■ 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.
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.
Chapter 3. Communications Operations of BHT-6000 ■ 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.
■ Phase 2 with EOT If the sending station receives an EOT anytime during phase 2, it shifts to phase 3 to terminate the message transmission abnormally. Even if the phase 3 terminates normally, the transmission results in an abnormal end. Receiving station Sending station EOT Occurrence of an error To phase 3.
Chapter 3. Communications Operations of BHT-6000 ■ Abnormal termination of phase 2 (Abort of phase 2) If the sending station receives no ACK from the receiving station after sending an ENQ nine times in succession, it sends an EOT to the receiving station after 3 seconds from the 9th ENQ to terminate this transmission sequence abnormally.
■ Phase 3 with iterated EOT 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 EOT sent, it iterates sending of an EOT at threesecond intervals up to ten times. If the sending station receives an ACK before sending an EOT ten times, it terminates the message transmission normally and releases the data link.
Chapter 3. Communications Operations of BHT-6000 [ 5 ] Aborting Data Transmission Pressing the C key aborts data transmission. If the C key is pressed during downloading, the BHT-6000 transmits an EOT and aborts the file transmission. If it is pressed during uploading, the BHT-6000 transmits the current transmission block followed by EOT and then aborts the file transmission.
[ 6 ] BCC for Horizontal Parity Checking To check whether data has been transmitted accurately, the BHT-6000 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.
Chapter 3. Communications Operations of BHT-6000 [ 7 ] 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 Byte position 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 Number of data texts contained (5 bytes) Program file name (12 bytes) Example of contents P R O G 1 .
■ Data Text Format (1) Heading text Number of fields (2 bytes) Length of data field 1 Length of data field n (2 bytes) (2 bytes) Byte position 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 Number of data texts contained (5 bytes) Data file name (12 bytes) Example of contents M A S T E R . D A T n 0 0 5 9 2 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).
Chapter 3. Communications Operations of BHT-6000 3.3.2 BHT-Ir Protocol [ 1 ] Overview The BHT-Ir protocol is the communications procedure for the serial infrared link, which is used to transmit files between the BHT-6000 and a host (or between the BHT-6000s). It adopts the response method using ACK/NAK codes. The BHT-Ir protocol can be used also for communications through the direct-connect interface.
[ 2 ] Control Characters The control characters are classified into two groups: transmission control characters and text control characters. (1) Transmission control characters The transmission control characters listed below are used to compose transmission control sequences in phases 1 through 3. Symbol Value Meaning Function DLE EOT 1004h End Of Transmission Releases a data link (Phase 3). Requests abort of transmission (Phase 2).
Chapter 3. Communications Operations of BHT-6000 (2) Text control characters The text control characters are used to format transmission texts. protocol, they include the following headers and a terminator. Symbol Value In the BHT-Ir Meaning Function DLE SOH 1001h Start Of Heading Indicates the start of heading text (Phase 2). DLE STX 1002h Start Of Text Indicates the start of data text (Phase 2). DLE ETX 1003h End Of Text Indicates the end of data text (Phase 2).
[ 3 ] Basic Format of Transmission Messages Basically, the BHT-6000 transmits data as units of a file. First, it transmits a heading text which includes the attribute information of a file (e.g., file name and the number of data texts) to be transmitted. Following the heading text, it transmits the data text in the file. A heading text and data text comprise a text.
Chapter 3. Communications Operations of BHT-6000 [ 4 ] Transmission Control Sequences Shown below is a typical message transmission sequence supported by the BHT-Ir protocol. This sequence example does not include transmission errors or negative responses.
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.
Chapter 3. Communications Operations of BHT-6000 ■ 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. Sending station Receiving station DLE ENQ and IDm (1) 0.
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.
Chapter 3. Communications Operations of BHT-6000 ■ Phase 2 with suspension of data reception for erasure of the flash ROM If the receiving BHT-6000 requires the flash ROM to be erased for receiving downloaded files, it sends a sequence of WACK and IDs to the sending station to suspend the data transmission. Upon receipt of the sequence of WACK and IDs, the sending station stops the data transmission until any response comes from the receiving station for one minute.
■ Phase 2 with a sequence of DLE NAK and IDs If the sending station receives a sequence of DLE NAK and IDs 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 a sequence of DLE ACK and IDs before receiving the sequence of DLE NAK and IDs 10 times in succession, it continues the subsequent message transmission.
Chapter 3. Communications Operations of BHT-6000 ■ Phase 2 with a sequence of DLE EOT and IDs If the sending station receives a sequence of DLE EOT and IDs anytime during phase 2, it shifts to phase 3 to terminate the message transmission abnormally. Even if the phase 3 terminates normally, the transmission results in an abnormal end. Sending station Receiving station DLE EOT and IDs Occurrence of an error To phase 3.
■ Abnormal termination of phase 2 (Abort of phase 2) If the sending station receives no sequence of DLE ACK and IDs from the receiving station after sending a sequence of DLE ENQ and IDs 59 times in succession, it sends a sequence of DLE EOT and IDs to the receiving station after 0.5 second from the 59th sequence of DLE ENQ and IDs and then aborts this transmission abnormally. Sending station 0.5 second 0.5 second Receiving station DLE ENQ and IDs (1) DLE ENQ and IDs (2) DLE ENQ and IDs (59) 0.
Chapter 3. Communications Operations of BHT-6000 ■ Phase 3 with iterated transmission of DLE EOT and IDs 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 EOT and IDs, it iterates sending of the sequence at 0.5-second intervals up to 60 times.
■ Phase 3 with timeout at the receiving station If the receiving station receives no subsequent text or normal sequence of DLE EOT and IDs within 30 seconds after sending a sequence of DLE ACK and IDs, it sends a sequence of DLE EOT and IDs and aborts the transmission abnormally. Sending station Data text #n Receiving station DLE ACK and IDs 30 seconds DLE EOT and IDs Abnormal termination [ 5 ] Aborting Data Transmission Pressing the C key aborts data transmission.
Chapter 3. Communications Operations of BHT-6000 [ 6 ] CRC To check whether data has been transmitted accurately, the BHT-Ir protocol supports CRC (Cyclic Redundancy Check) which employs the CRC-16 generating system. In CRC, a CRC character is suffixed to a sequence of DLE ETX of every transmission block.
[ 8 ] Text Format Text should be formatted according to the standard of the BHT-Ir 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 Byte position 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 Number of data texts contained (5 bytes) Program file name (12 bytes) Example of contents P R O G 1 .
