2. Configuration

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.
