change the strap setting, lift the jumper strap connector off and
reinsert it in the new position. Figure 3-2 shows a typical strap

Caution: Only personnel familiar with DIP switch selection
should change switch positions or the ground strap from
factory settings. Changes should be made only during setup.

Signal Ground

Signal ground is normally isolated from frame ground
(factory). If interference exists, connect signal ground to frame
ground by moving the strap.
