Powering the SR31T

SR31T Tethered Scanner User’s Guide 3

The SR31T is powered through the accessory cable that connects it to
the host computer. Depending on the interface type you are using,
power for the SR31T is supplied either directly by the host computer
or comes from an external power supply connected to the interface
cable.

Chapter 1 — Introducing the SR31T Tethered Scanner

Connecting the Interface Cable

The cable you use depends on your host device and interface. See the
cable list in the Required Accessories section on page 6 for a list of
common cables and Chapter 3, SR31T Interfaces, for full details on
how to connect your product to the different interfaces supported.

All cables are connected to the scanner in the same way - insert the
SR31T cable connector into your product’s cable socket and push
firmly until you hear or feel a click.

If your cable is electrically supplied by the host or an external power
supply, the SR31T will beep and vibrate and the blue Intermec-Ready­to-Work indicator™ LED will come on (default settings).

Chapter 2 — Scanning with the SR31T Tethered Scanner

Understanding the Lights

The SR31T uses the Intermec Ready-to-Work™ light and Status light
to communicate information about your scanner.

Blue Intermec Ready-to-Work Indicator

The blue Intermec-Ready-to-Work indicator™ 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).

For example, while the blue Intermec-Ready-to-Work LED is on, the
scanner will flash green when you have successfully scanned and
transmitted a bar code.

Using Vibrate Alert

You can configure the SR31T to vibrate when it successfully decodes a
bar code. This feature can be useful in these situations:

• You are in a noisy environment, such as a busy warehouse, where it

can be difficult to hear the beeps.

• You are working in a quiet environment, such as a library, where

Scanning Bar Codes

For the SR31THP 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.

Chapter 2 — Scanning with the SR31T Tethered Scanner

Use the appropriate SR31T scanner model for your scanning
requirements:

• the SR31T1D model contains a 1D imager to scan 1D bar code

symbologies

• the SR31T2D models contain a 2D imager which can read both

1D and 2D bar code symbologies

• the SR31THP model contains a high performance 2D imager

which can also read both 1D and 2D bar code symbologies

The scanner model you are using and the type of bar code you are
decoding determine the way you scan the bar code.

SR31T Tethered Scanner User’s Guide 13

Chapter 2 — Scanning with the SR31T Tethered Scanner

When you unpack the SR31T, the following bar code symbologies are
enabled by default:

All models (1D and 2D)

Hands-Free Scanning

The SR31T 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 in Chapter 4).

Autostand Triggering Mode

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

• Autostand for the SR31T1D

16 SR31T Tethered Scanner User’s Guide

• Autostand for 2D models (SR31T2D, SR31THP)

Chapter 2 — Scanning with the SR31T Tethered Scanner

Autostand for the SR31T1D

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.

Autostand for 2D Models (SR31T2D, SR31THP)

When using 2D and HP models, Autostand is a mix of Level and
Presentation 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 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.
