Appendices Appendix B. Communications Protocol Details B.1 BHT-protocol [ 1 ] 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.
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. Sending station Receiving station ENQ(1) 3 seconds ENQ(2) 3 seconds ENQ(3) ENQ(10) 3 seconds EOT Abnormal termination TIP The receiving station's default timeout is 30 seconds.
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.
Appendices ■ 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.
Appendices ■ 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.
Appendices [ 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.
[ 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.
Appendices B.2 BHT-Ir protocol [ 1 ] 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.
Appendices ■ 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) 0.5 second DLE ENQ and IDm (2) 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.
Appendices ■ 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.
■ 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.
Appendices ■ 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.
Appendices ■ 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 [ 2 ] Aborting Data Transmission Pressing the C key aborts data transmission.
Appendices [ 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.
