Page 114 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. Vertical Parity A vertical parity bit is a redundancy bit which is added to every character to be transmitted in order to check that data has been transmitted accurately. The parity bit should be set to "1" or "0" depending upon the parity parameter setting, to make the number of set bits in the character even or odd. The receiver counts the number of set bits in the transmitted character code to make sure that it has the selected number (even or odd) of set bits. The vertical parity bit is positioned immediately following the MSB (Most significant bit) as shown below. ...

Page 145: Charging The Rechargeable Battery Cartridge (Using The Cu-8001/8021)
If a Ni-MH battery undergoes many cycles of imperfect charging and discharging (e.g., one-hour recharge followed by one-hour use), the operating time may become short before the service life is really expired, just as the battery memorizes the use conditions. It is called "Memory Accumulation." The memory accumulation can be avoided by discharging a Ni-MH battery fully before charging (called "refresh"). For refreshing the battery cartridge, use the CU-8001/8021 or C-600. If left unused for a long time, the battery cartridge may have been inactive. Charge and discharge such a battery cartridge several times before use. 5.5.1 Rechargeable Battery Cartridge Loaded in the BHT (1) Turn the CU-8001/8021 on. The POWER LED comes on. (2) Place the BHT loaded with a rechargeable battery cartridge onto the CU-8001/8021. The CU-8001/8021 lights the CHG1 LED and starts charging. The charging time is approx. 8 hours.

Page 165 Appendices 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. ...
Page 166 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, then it sends an EOT to the receiving station after three seconds from the 10th ENQ to terminate the message transmission abnormally. The receiving station's default timeout is 30 seconds. You may modify the timeout length on the SET PROTOCOL screen in System Mode (pp. 58 and 60) or by using the XFILE statement (refer to the "BHT-BASIC Programmer's Manual"). ...
Page 167 Appendices 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. ...
Page 168 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, then 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. If the sending station receives a NAK 10 times in succession or it fails to send a same transmission block, then 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. ...

If the sending station receives an ACK before sending an EOT ten times, it terminates the message transmission normally and releases the data link. Abnormal termination of phase 3 If the sending station receives no ACK from the receiving station within three seconds from the 10th EOT, it terminates the message transmission abnormally and releases the data link. ...
Page 172: [ 2 ] Aborting Data Transmission
[ 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. In the BHT-protocol, every parity bit of BCC is set so that all set bits at the same bit level (including a parity bit) in the characters contained in the transmission block have an even number by binary addition, excluding SOH, STX, and functions SOH$ and STX$. (For details about SOH$ and STX$ which are protocol functions unique to BHT-BASIC, refer to the "BHT-BASIC Programmer's Manual.") Shown below is a data text block indicating the bits to be added for horizontal parity checking. ...
