POWER SOURCE JUMPER SETTINGS
For most applications input power is provided through the dedicated spring clamp connectors inside the CBX500.
However CBX500 may accept power from the connected reading device through the 25-pin connector. This is
useful, for example, to pass power to connected accessories such as Encoder and Presence Sensor from DX8200A
VAC models or 6K/8K scanners powered directly through the network. See the relative reading device Reference
Manual for details.
To power CBX500 from the reading device, the power source jumper must be placed in the "power from device"
position as indicated in Figure 6.

SHIELD TO PROTECTION EARTH 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.

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.
