Chapter 2 — Scanning with the SG20T

Understanding the Lights

The SG20T uses the Intermec Ready-to-Work™ light and Status light to communicate information about your scanner.

Intermec Ready-to-Work Indicator

The Intermec-Ready-to-Work indicator™ (blue LED) indicates that the scanner is ready to scan bar codes. This light stays on all the time when the scanner is ready to work however your scanner will also flash status information using green and red lights. See the Status Light information in the next section.

Blue Intermec Ready-to-Work Indicator

Light State

Off

What it Means

Scanner is not ready to scan bar codes.

The SG20T is ready to scan bar codes.

Note: By default the Intermec Ready-to-Work light is enabled however you can disable the light if desired. You can also change the color. See

EasySet version 5. 6. 5. 1. for more information.



Status Light

The status light on the SG20T flashes red or green depending on the status of the scanner.

Default Status Light Description

Light State What it Means

Series of green flashes (USB interface only)

Green light on for 2 seconds

Scanning Bar Codes

For the SG20THP and SG20THPHC do not look directly into the window area or at a reflection of the laser framing beam while scanning. Long-term exposure to the laser framing beam can damage your vision.

The SG20T contains either a 1D linear imager (SG20T1D) or 2D area imager (SG20THP or SG20THC) to scan bar code data. The type of scan engine you are using and the type of bar code you are decoding determines the way you scan the bar code.

When you unpack the SG20T, these bar code symbologies are enabled:

•

Code 39

•

Code 128 / GS1-128

•

EAN/UPC

•

PDF417 (SG20THP and SG20THPHC only)

•

DataMatrix (SG20THP and SG20THPHC only)



If you are using bar code labels that are encoded in a different symbology, you need to enable the symbology on your SG20T. Use

EasySet version 5.6.5.1 or later to enable and disable symbologies for your scanner.

To scan a bar code label with a 1D linear imager

1

Point the SG20T at the bar code label and hold the SG20T at a slight angle 15 to 25 cm (6 to 10 in) from the label.

2

Pull the trigger, and direct the red beam so that it falls across all bars in the bar code label.

Use this test bar code:

Code 39 Test Bar Code

*123456*

*123456*

Tip: Depending on your screen resolution, you can scan bar codes displayed on your computer screen.

By default, when the SG20T successfully reads a bar code label, the

SG20T beeps one time, the status light briefly turns green, and the scanner beam turns off.

3

Release the trigger.



14

Scanning Bar Codes: The aiming and scanner beams that you see depend on which SG20T model you are using.

To scan omni-directionally with the 2D high performance area imager

1

Point the scanner window at the bar code label and hold the

SG20T steady a few inches from the label.

2

Pull the trigger and use the laser framing to position the imager over the bar code or area to capture.

30°

20°

SG20THP Laser Framing

When bar code labels are printed close to each other, try to frame only the bar code you want to read, to avoid reading the wrong bar code.



By default, when the SG20T successfully reads a bar code label, the

SG20T beeps one time, the status light briefly turns green, and the scanner lighting turns off.

3

Release the trigger.

Hands-Free Scanning

The SG20T is a handheld scanner however you can scan items without having to hold your scanner in your hand. To do hands-free scanning, you will need to change the triggering mode to Autostand.

To activate, see

“Hands-Free Scanning” on page 29

.

Autostand Triggering Mode

Autostand mode is different depending on the scanner model. This section explains the difference between:

•

Autostand for SG20THP/SG20THPHC and

•

Autostand for SG20T1D

Autostand For SG20THP or SG20THPHC

Autostand is a mix of Level and Presentation triggering modes. When in Level mode you simply pull the trigger to scan a bar code (hand held scanning). After a period of inactivity the scanner switches to

Presentation mode (configurable timeout). In this mode the scanner turns on automatically when it detects movement in front of the scanner window. This allows you to use your scanner for hands-free scanning. To return to Level mode pull the trigger.

Autostand For SG20T1D

When using the 1D model Autostand is a mix of Level and Flashing triggering modes. When in Level mode you simply pull the trigger to scan a bar code (handheld scanning). After a period of inactivity the scanner switches to Flashing mode (configurable timeout). When the scanner is flashing you can present a bar code in front of the scanner window and it will be scanned. To return to Level mode pull the trigger.
