Scanner Features

This chapter describes the features of the standard and extended range,

undecoded scanners. Included are descriptions of:

• major features

• LEDs

• scanning ranges

• safety labels

• accessories

1–2

Publication 2755-6.1

Scanner Features

The scanners use a low power visible (red) laser diode for scanning. The

trigger turns on the laser which scans a label at approximately 36 scans

per second.

Trigger

Cable Connector

LEDs

The laser beam:

-exits through the scan window

-reflects off the label back through the window

-is detected by a sensor in the scanner

When a label is read, the laser beam is automatically turned off until the

trigger is pressed again. If no label is read, the laser beam automatically

turns off after approximately 3 seconds and remains off until the trigger

is released and pressed again.

Note: The Extended Range Scanner (Catalog No. 2755-HUG-9) has a

two position trigger. The first detent provides a spotter beam and the

second position provides a scan line.

Publication 2755-6.1

LED Indicators

On the back of the scanner there is a clear window through which two

LEDs are visible.

Green

Red

Green LED = Good Read, indicating that a bar code symbol has been

scanned and decoded. LED remains on until the next scan

(trigger pressed).

Red LED = Scanning, indicating that the laser light is on.

1–4

Publication 2755-6.1

Safety Labels

The scanners use a low power visible laser diode. As with any bright

light source, you should avoid staring directly into the beam.

Momentary exposure to a CDRH Class II laser is not known to be

harmful.

The following figure shows the location of all safety labels as they

appear on the scanner.

!

ATTENTION: Do not install or remove the scanner

cables or connectors until the power to the scanner and

decoder is turned off. Failure to follow this caution may

result in damage to the scanner or decoder.

!

ATTENTION: Make sure you use the Series B Gun

Adapter (Catalog No. 2755-NC16, Series B). If you are

ugrading from an earlier version Allen-Bradley hand-held

scanner (such as the 2755-G2 or -G3) which used the

Series A gun adapter, you will need to purchase the series

B gun adapter.

The 2755-NC16 Gun Adapter connects to the decoder input port as

shown below for the Enhanced Decoder, the High Speed Decoder is

similar.

Publication 2755-6.1

Operating the Scanner

1. Check your connections.

• Is the scanner cable securely attached?

• If connecting to a High Speed or Enhanced

decoder, is the Gun Adapter present?

• Is power applied to the decoder?

2. Test the scanner

Aim the scanner at the work

surface and press the trigger.

You should see the red beam

on the work surface, and the

red LED on the back of the

scanner should be on.

3. Scan a label.

Scan a bar code. Adjust the

scanner position so that the scan

beam is centered on the bar

code and overlaps both sides.

When the scanner has read a

symbol:

• You will hear a beep from the

decoder (if enabled).

• The green LED will turn on

and remain on until the next

scan.
