2.1 RS-232 serial interface
2.1.1 Specifications
Data transmission: Serial
Synchronization: Asynchronous
Handshaking: DTR/DSR or XON/XOFF control
Signal levels: MARK= -3 to –15V: Logic “1”
SPACE= +3 to +15V: Logic “0”
Baud rage: 4800, 9600, 19200, 38400,57600,115200 bps
Data word length: 7 or 8 bits
Parity Settings: None, even, odd
Stop bits: 1 or more
Connector (printer side): Female DSUB-25 pin connector
☞NOTE: The data word length, baud rate, and parity depend on the
Software-Tool settings.
2.1.2 Switching between on-line and off-line
The printer does not have an on-line/off-line switch.
The printer goes off-line:
•Between when the power is turned on (including reset using the interface)
•During the self-test.
•When the cover is open.
•During paper feeding using the paper feed button.
•During macro executing stand by status.
•When a temporary abnormality occurs in the power supply voltage.
•When an error has occurred.
