Interface Type
This parameter configures the electrical interface for the serial port, as
follows:
•
RS-232 (the default)
•
RS-422
Data Protocol
You may select one of the following serial interface protocols to meet the host
interface requirements.
•
XON / XOFF (the default) — Transmit On / Transmit Off. The printer
controls the flow of communication from the host by telling the host to turn
the transmission on and off. This is the factory default serial protocol.
•
ETX / ACK — End of Text / Acknowledge. The host controls the flow of
communication to the printer by sending a block of data and ending the
block with an End of Text (ETX) signal. When the printer receives the
ETX signal, it will acknowledge it has received the entire block of data.
•
ACK / NAK — Acknowledge / Negative Acknowledge. ACK means
acknowledge; the device acknowledges it has accepted a transmission.
NAK means a negative acknowledge; the device did not receive the
transmission.
•
DTR — (DTE Ready). The printer controls the data flow by asserting or
de-asserting this hardware signal to the host. If there is enough room in
the printer buffer, the printer will send a high signal; if the buffer is full the
printer will send a low signal. DTR tells the host if it is safe to send more
data. (If the host sends data during an unsafe condition, data will be lost.)
Baud Rate
This parameter sets the baud rate of the serial interface in the printer. Baud
rate is the speed at which serial data is transferred between the host
computer and the printer.
•
600 BAUD
•
1200 BAUD
•
2400 BAUD
•
4800 BAUD
•
9600 BAUD (the default)
•
19200 BAUD
•
38400 BAUD
•
57600 BAUD
•
115200 BAUD
