Setting Up the LS 2106
Introduction
The LS 2106 hand-held laser scanner offers excellent performance in retail and light
industrial applications. Advanced ergonomic design ensures comfortable use for extended
periods of time.
The LS 2100 Series hand-held scanner is based on the SE 1200 Series scan engine, mylar
®
scan element and the Visible Laser Diode (VLD). This state of the art technology gives the
scannera wider decodezone,greater depth offield,and a visiblescan beam. Thismodelreads
color bar codes and symbols printed on all substrates. See the LS 2106 Decode Zone on page
2-4.

All leading OCIA terminals, including NCR, Nixdorf, and ICL terminals.
s Dual RS-232 Hosts
s Popular OCR terminals, such as Fujitsu and ICL.

LS2106-TheLS2106scannerisakeyboard“wedge”interfacewhich adds efficient,
reliable bar code reading to your PS/2 or AT/XT terminal. Since entered scan data is
transmitted as keystrokes, no software changes to the host system are necessary. The
scanner contains on-board discrete keyboard wedge communications for connecting
to asynchronous terminals and host systems. It can also accommodate any of the
Synapse™ “Smart Cables” which allows you to connect to a wide variety of host
systems. Some installations require one cable; others require additional adapters
between the keyboard, the PC, and the y-cable.
All of the LS 2100 series scan automatically at the rate of 36 scans per second. For decode
capability, see Technical Specifications on page 3-3.
Audience
The intended audience for this manual is personnel performing installation/setup and
programming of LS 2106 scanners.

Scanning with the LS 2106
Introduction
This chapter covers the proper techniques for scanning bar codes and the decode zone for the
LS 2106 scanner.
Scanning with the LS 2106
Before you can use the scanner, it should have already been installed and programmed. If not,
refer to Chapter 4, Parameter Menus for instructions on programming your scanner. If you
need assistance, contact your local supplier or Symbol Techologies.
1. Before you use the scanner, make sure all cable connections are secure.
2. Make sure the bar code is in the correct scanning range. Aim and press the trigger;
the scan beam lights and an orange light illuminates at the rear of the scanner. The
scanner has read the symbol when:
s You hear a beep.
s The orange light turns green.
s The laser turns off.
