SOURCE 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.

ID-NET/HOST SHIELD JUMPER SETTINGS
The Network shield (Shield) can be connected to Earth Ground (Earth) either directly or through a filter circuit. If
the jumper is left open, the network cable shield (Shield) is floating.
NETWORK BUS TERMINATION
The ID-NET™ termination resistance switch enables or disables the insertion of the bus termination resistor for
ID-NET™ network applications.
In ID-NET™ network applications the termination resistor must be enabled ONLY on the first
and last devices of the chain. On all the other devices this resistor MUST NOT be enabled
(OFF).
