The M-Series Printer, with the RS-232 Serial Interface, uses eight
miniature switches located on the rear of the printer, above the
Signal Interface Cable Connector. The ON/OFF positions of these
switches establish some of the Printer Configuration Parameters.
Bank 1 switches must be
properly positioned to
establish serial data
communications with the host
computer. Thereafter, the
position of these switches
should not be changed.
Note: Parallel-interface
printers do not require
these configuration
parameters, therefore
they have no Bank 1
switches.
If these switches are in the
proper position to match the
communication configuration
of the host computer, and the
printer is not receiving data,
refer to the Interconnections
Section and make sure the
correct interface cable is
being used.
Note: The printer is fixed at
1 stop bit, so make sure
that your host device is
also set at 1 stop bit.
