NOTE: To avoid electromagnetic interference:

- Connect CBX500 Protection Earth (Earth) to a good earth ground.

- Connect the reading device chassis to earth ground through the jumper,

(default setting, see Figure 8).

- Connect the Network Cable Shield (Shield) to Filtered Earth through the

jumper (default setting, see Figure 7).

CAUTION: Do not connect to the Main Interface spring clamp terminals if

using Host Interface Modules (Fieldbus or non-Fieldbus).

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.
