installed. (When the
SAA PCB
is installed, the rear panel
is internally connected to it, and the and other
functions are passed to the hybrid from the SAA
as
required.
When the SAA is not installed, the rear panel DB15 goes directly
to the hybrid.
Without the SAA installed,
OFF
and
ON
control requires a
momentary closure
to
ground. It
is
a standard input pulled-up
with a 2.2 resistor. Thus, it may be connected directly to
switches or
may
be driven by an open collector or
logic output as desired.
If
the “Super” Auto-answer board is installed, refer to
its
manual
section for details on remote control operation.
