RS-232 SERIAL COMMUNICATIONS INTERFACE
This Connection provides a serial transmission data communications link to
the STM-100 / MF. Four standard baud can be selected: 300, 1200, 2400, and
9600. They are selected via the rear panel configuration dip switches. (See
Section 2.5) The serial interface communications protocol is also selectable on
these switches. The choices are SEMI STANDARD SECS-II, or Sycon format.
The electrical specifications correspond to the RS-232 standard.
