HOST INTERFACE
118
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, and 38400 Baud.
NOTE: If you select a baud rate that is greater than 19200, you may
need to use RS-422 to prevent data loss. You also may need to
increase the Buffer Size in K parameter from the default (1
Kbyte) 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
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 Terminal 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. 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.
•
False. Never asserts the DTR signal.
