Chapter 3. Communications Operations of the BHT Chapter 3 Communications Operations of the BHT This chapter describes the communications operations of the BHT-7500/7500S/7500W— the spread-spectrum communication (for BHT-7500S/7500W only), IR communication, RS-232C interface specifications, the basic communications specifications, and the communications protocols—for data transfer with the host computer or other devices. 3.1 3.2 3.3 3.4 3.5 Spread-Spectrum Communication (BHT-7500S/7500W only) ..........
3.1 Spread-Spectrum Communication (BHT-7500S/7500W only) 3.1.1 Notes for Wireless Operations • If there are too many communications errors, first make sure that the BHT points directly at an access point because the 2.4-GHz band requires a more or less straight line path. Note also that the low-power radio waves have trouble passing through human bodies and other obstacles along that path.
Chapter 3. Communications Operations of the BHT ■ Security IDs For assuring higher security, set security IDs to the BHTs. Those IDs should match those of the access points. Usually, use a same security ID for a company or a department (or section). For the setting procedure of security IDs, refer to Subsection 2.5.3, [ 8 ] RF Menu. BHT-7500W For the setting procedure of RF-related parameters, refer to Subsection 2.5.3, "[ 8 ] RF Menu BHT-7500W.
3.2 Infrared Communication The BHT has an integrated infrared (IR) communications device which enables wireless transfer of programs and data between the BHT and the host computer and between the BHTs, instead of the conventional wire transfer.
Chapter 3. Communications Operations of the BHT 3.3 RS-232C Interface Specifications [ 1 ] Interface Connector and Pin Assignment The BHT 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 to a host computer (or another BHT) directly without any routing through the CU-7000.
[ 2 ] Interface Cable Connection Connect the BHT directly to a host computer, a modem, or a printer with a directconnect interface cable as illustrated below.
Chapter 3. Communications Operations of the BHT 3.4 Basic Communications Specifications and Parameters 3.4.1 Basic Communications Specifications Listed below are the communications specifications when the BHT exchanges data with a host computer through the CU-7000 (optical interface) or direct-connect interface cable.
■ 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 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.

3.5 Communications Protocols The BHT supports both the BHT-protocol and the BHT-Ir protocol for file transmission. 3.5.1 BHT-protocol [ 1 ] Overview The BHT-protocol is the communications procedure used to transmit files between the BHT and a host (or between the BHTs). It adopts the response method using ACK/NAK codes.
Chapter 3. Communications Operations of the BHT [ 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).
(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). You may designate values of headers and a terminator with the protocol functions in BHT-BASIC.
Chapter 3. Communications Operations of the BHT [ 3 ] Basic Format of Transmission Messages Basically, the BHT 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.
[ 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 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 .

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 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 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 transmits an EOT and aborts the file transmission. If it is pressed during uploading, the BHT 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 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 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 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.
