81 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 communica- tions protocols--for data transmission with the host computer or other devices.
82 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.
83 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 direct- connect interface cable as illustrated below.
84 3.2 Basic Communications Specifica- tions 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.
85 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 transmis- sion bit order is LSB (Least significant bit) first.
86 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. Transmission Speed 2400, 9600, 19200, 38400, 57600.
87 Chapter 3. Communications Operations of BHT-6000 3.3 Communications Pr otocols The BHT-6000 supports both the BHT-protocol and the BHT-Ir protocol for file trans- mission. 3.3.1 BHT -pr otocol [ 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).
88 [ 2 ] Contr ol Characters The control characters are classified into two groups: transmission control characters and text control characters. (1) T ransmission control characters The transmission control characters listed below are used to compose transmission control sequences in phases 1 through 3.
89 Chapter 3. Communications Operations of BHT-6000 (2) T ext 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).
90 S O H E T X B C C S T X E T X B C C S T X E T X B C C [ 3 ] Basic Format of T ransmission 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.
91 Chapter 3. Communications Operations of BHT-6000 ENQ S O H ACK ACK ACK ACK ACK EOT ACK E T X B C C S T X E T X B C C S T X E T X B C C S T X E T X B C C [ 4 ] T ransmission Contr ol Sequences Shown below is a typical message transmission sequence supported by the BHT- protocol.
92 ACK ENQ 3 seconds 3 seconds ENQ ENQ ENQ ACK 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.
93 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.
94 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.
95 Chapter 3. Communications Operations of BHT-6000 NAK NAK NAK NAK NAK ACK ■ 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.
96 EOT 3 seconds 3 seconds ENQ ENQ ACK ■ 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.
97 Chapter 3. Communications Operations of BHT-6000 EOT ACK 3 seconds 3 seconds ENQ (1) ENQ (2) EOT ENQ (9) 3 seconds ■ Abnormal termination of phase 2 (Abort of phase 2) If the sending station rece.

103 Chapter 3. Communications Operations of BHT-6000 3.3.2 BHT -Ir Pr otocol [ 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).
104 [ 2 ] Contr ol Characters The control characters are classified into two groups: transmission control characters and text control characters. (1) T ransmission control characters The transmission control characters listed below are used to compose transmission control sequences in phases 1 through 3.
105 Chapter 3. Communications Operations of BHT-6000 (2) T ext contr ol characters The text control characters are used to format transmission texts. In the BHT-Ir protocol, they include the following headers and a terminator. Symbol Value Meaning Function DLE SOH 1001h Start Of Heading Indicates the start of heading text (Phase 2).

107 Chapter 3. Communications Operations of BHT-6000 [ 4 ] T ransmission Contr ol 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.
108 Data transmission may accidentally involve various types of errors. The BHT-Ir proto- col is designed to recover from those errors as frequently as possible.
109 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.
110 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.
111 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.
112 ■ 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.
113 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.
114 ■ 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.
115 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.
116 ■ 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.
117 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.
