Anadex DP-9000 - Serial Interface Connector J2 Pin

GROUr-1DS
- Two grounding systems are used in the printer:
SIGNAL CO}MON and CHASSIS GROUND. These two
systems are DC isolated from each other, and
are capacitively coupled for filtering. Nor-
mally these grounds should not be shorted
together either in the interface cable or at
the data source. Ground loops and communi-
cations interference may occur~

*NOTE: If RTS, DSR, CTS,
and CD are not actively
used by the data source
there should be no connec-
tion to these pins to
prevent the introduction
of noise and 'conflicting
logic levels to the printer.
If they are to be used,
then straps A, B, and C
should be cut (See
Figure 2-9).
