The settings described should only be

Patton printed circiut boards (PCBs or cards) that include optional circuit configu-
rations have built in strapping features.
In this manual, strap options for the card are described under separate headings
with numbered paragraphs for each strap function. Additionally, a strapping
instruction figure is provided for the card. Each figure contains the following
strapping aids:
A nonscale drawing showing the relative location of each wire
strap and each miniature switch.
A nonscale drawing of each miniature switch showing the
standard and mandatory setting for each switch segment.
Tables summarizing the strapping, the standard setting and the
paragraph reference for each strap function.
The features set at the factory are implemented through miniature switches. The
miniature switch occupies a dual inline package (DIP) component location on the
card. The switch location can be referenced by the switch number silkscreened on
the PCB. Switch 1 (SW1) is currently not used on this version of the 2031
Turbo
and the switch segment positions make no difference.
Hardware (Berg) strapping is accomplished through the use of pins that protrude
from the PCB and can be connected by an insulated shorting bar. The arrange-
ments of the Berg straps are
