Chapter 4 HOST INTERFACE Menu
Baud Rate
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.
The choices for the RS-232 and RS-422 interfaces are 600, 1200, 2400,
4800, 9600, 19200, 38400, 57600, and 115200 Baud. The default is 9600
Baud.
NOTE: If you select a baud rate that is greater than 19200, you may need to
use RS-422 or select a lower baud rate to prevent data loss. You also
may need to increase the Buffer Size in K parameter to improve
performance.
Word Length
Sets the length of the serial data word. The length of the data word can be set
to 7 or 8 bits, and must match the corresponding data bits setting in the host
computer.
Stop Bits 1
Sets the number of stop bits in the serial data word. Either one or two stop bits
can be selected. The setting must match the corresponding stop bit setting in
the host computer.
Parity
Set for odd parity, even parity, mark, sense, or no parity. The setting must
match the corresponding parity setting in the host computer.
Data Term Ready
This configuration is part of hardware flow control and determines when the
Data Terminal Ready (DTR) signal is generated. This signal indicates if the
printer is ready to receive data.
• True (default). Continuously asserts the DTR signal.
• On Line and BNF (buffer not full) . Asserts the DTR signal when the
printer is online and the internal serial buffer is not full.
• Off Line or BF (buffer full) . Asserts the DTR signal when the printer is
offline or the internal serial buffer is full.
• On Line . Asserts the DTR signal when the printer is online.
• False . Never asserts the DTR signal.
