ERIAL ORT APPLIES TO THE
One way to set up the RS-422 serial port for communication between the Elite 12
Series and the PC is to type the following MS-DOS command before printing:
The above MODE command configures the PC serial port for a baud rate of
9600, no parity, 8 data bits, 1 stop bit, and for XON/XOFF flow control. These
settings match the Elite 12 Series's RS-422 front panel factory default settings.
XON/XOFF flow control is widely used, but check your application's documenta-
tion to see if that handles this protocol. It is important that the application
support XON/XOFF because standard DOS commands such as PRINT and COPY
cannot.
However, we recommend that instead of XON/XOFF flow control, you use DTR
flow control. DTR flow control is preferred because DOS has better support for
it, as it matches the flow control preferred by Windows and thus provides more
reliable communication when sending PCL jobs to the printer. To use DTR flow
control, type the following MS-DOS command before printing:
Note: You will need to change the Elite 12 Series' RS422 Flow Control submenu
setting to DTR if you use this MODE command.
Note: In both the parallel and serial MODE command examples shown in this section, the
P switch at the end of the command may be replaced by the B switch. The B switch is
available with MS-DOS version 4.0 and later.
R DOS
EDIRECTING TO A SERIAL PORT
DOS and some DOS applications only print through a parallel port. If you set up
the Elite 12 Series to print through the RS-422 serial port, you will need an
additional MODE command to redirect your output to the serial port. The
following command should be typed after the previous serial port MODE
command:
This command redirects to serial port COM1 the output that DOS or your DOS
application would normally send to the parallel port. If you use a different serial
port (i.e., COM 2, 3, or 4) substitute that number.
Note: A more efficient way of using the MODE commands is to add them to
your AUTOEXEC.BAT file. Refer to your PC documentation for information about
editing the AUTOEXEC.BAT file.
