CHASSIS GROUNDING JUMPER SETTINGS
The reading device chassis grounding method can be selected by positioning a jumper (see
Figure 8). In this way the reading device chassis can be connected to earth ground (only if
pin Earth is connected to a good earth ground). For all reading devices except 6K/8K, the
chassis can alternatively be connected to the power supply ground signal (GND) or it can be
left floating but, in this case, the jumper must be removed. For 6K or 8K scanners the chassis
is internally connected to GND.
