3.3.3 BHT-Ir
Specifications
The printer also supports BHT-Ir communication specified by DENSO CORPORATION.
The printer can receive data from the 'BHT-6500' made by DENSO CORPORATION when Data Input Mode
SWDIP2-1 and SWDIP2-2 is selected to BHT-Ir.
The inherent processing of the printer for BHT-Ir communication is shown below:
See BHT-Ir protocol specification for details of the protocol.
(1) ID
Printer ID: 3445H (fixed)
(2) Text
format
Only text is valid.
Files with 'PD3', 'FN3' or 'EX3' extension can not be processed.
(3) Input buffer full processing when receiving header.
Upon receiving the header, the printer inhibits connection with the host device when the remaining
amount of the input buffer becomes 512 bytes or less after subtracting the field number of the data text
indicated in heading text.
(4) Input buffer full processing when receiving data
Upon receiving data, the printer sends WACK supervisory sequence to a host device for requiring
temporarily delay of the data output from the host device as the input buffer full state when the
remaining amount of the input buffer is 255 bytes or less.
Then, the printer sends the ACK supervisory sequence to the host device to restart data transmission
when the remaining amount of the input buffer is 512 bytes or more.
The printer transfers the EOT supervisory sequence and stops when the input buffer full status
continues more than 1 minute.
(5) Command response processing during BHT-Ir transmission
No response command is transferred in BHT-Ir transmission mode.
Although response data is generated, it is discarded.
