Duet

™ Scanner

Speaker

The speaker produces an audible indication of scanner operation.

The tones are:

• Normal Tone – A single tone when the scanner reads a

bar code indicates a good read.

• Passed Selftest – A series of four tones are emitted when

power is first applied to the scanner. This indicates the

scanner passed the Selftest and is operating properly.

• Error Tone – The speaker sounds a series of tones

alerting the operator of a possible system or component

failure. If your scanner exhibits this behavior or behaves

erratically, contact your service personnel.

Connectors

Interface Connector

This connector provides the link between the scanner and the host

terminal. It transmits bar code data and, depending on your system

configuration, can also, supply power to the scanner from the host

terminal.

D.C. Power Connector

The DC power connector is for connecting the optional AC/DC

power supply to the scanner. This power supply is not required if

the scanner uses the Power-Off Terminal (P.O.T.) feature.

WARNING

Use only AC/DC Power Supplies approved for the

Duet

scanner

and ordered from PSC. Use of other power supplies may cause

damage to the product which is not covered by the factory

warranty.
