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.

All Reading Devices (except 6K/8K)

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.

OFF ON

Figure 10 – ID-NET™ Termination Resistance Switch

The ID-NET™ termination resistance switch enables or disables the insertion of the bus termination resistor for

ID-NET™ network applications.

CAUTION

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).
