Page 23: Bht-5000 System Configuration
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.
Page 24 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.
Page 25 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.
Page 26 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.
Page 27 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.

Page 91 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 transmis- sion bit order is LSB (Least significant bit) first.
Page 92 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.

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...
Page 95: Control Characters
(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.
Page 96 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."...
Page 97: Basic Format Of Transmission Messages
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.
Page 98: Transmission Control Sequences

This sequence example does not include transmission errors or negative responses. Sending Receiving Station Station Establishment of...
Page 99 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.
Page 100 Chapter 3. Communications Operations of BHT-5000 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.
Page 101 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.
Page 102 Chapter 3. Communications Operations of BHT-5000 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.
Page 103 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. Sending Receiving station...
Page 104 Chapter 3. Communications Operations of BHT-5000 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.
Page 105 Phase 3 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 EOT sent, it iterates sending of an EOT at three- second intervals up to ten times. If the sending station receives an ACK before sending an EOT ten times, it termi- nates the message transmission normally and releases the data link.

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...
Page 107: Bcc For Horizontal Parity Checking
3.3.6 BCC for Horizontal Parity Checking To check whether data has been transmitted accurately, the BHT-5000 supports hori- zontal 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.
