Setting Up the Scanner

Power Options

Depending on the peripherals used, the scanner receives power from one of two sources:
• Via the host through the host cable: If the host can supply 500mA of power, the host cable is less than 8.5' long, and there
are no peripheral devices in the configuration.
• Via an external power supply: When the host cannot provide sufficient power, the host cable length is more than 8.5' long,
or a peripheral device is connected to the hand-held and/or scanner ports. The external supply connects directly into the DC
port or through a host cable with an adapter or Y-connection.
When the scanner receives power, the green LED lights and three short high beeps sound, indicating that the scanner is operational.
