Chapter 1 Setting Up the LS 2100 Introduction The LS 2100 Series of hand-held laser scanners 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 with Visible Laser Diode (VLD) and mylar ® scan element. This state of the art technology gives the scanner a wider decode zone, greater depth of field, and a visible scan beam.
LS 2100 Product Reference Guide ! complete line of Symbol Technologies portable terminals and the full range of SYMBOL and OmniLinkTM interface controllers. LS 2104 - With a simple cable change, this scanner is compatible with: " RS 232C asynchronous terminals " SynapseTM “Smart Cables”, which allow you to connect to: " IBM 4683/4, 4693/4 series of terminals " All leading OCIA terminals, including NCR, Nixdorf, and ICL terminals " Popular OCR terminals, such as Fujitsu and ICL.
Setting Up the LS 2100 Setting Up the LS 2100 Installing the Cable Insert the cable into the receptacle on the bottom of the scanner, as shown below: Figure 1-2. Installing the Cable Switching Cables Different cables are required for different hosts. To change the scanner cable: 1. Press the tab on the cable with a small screwdriver. 2. Pull the cable out of the receptacle on the bottom of the scanner.
LS 2100 Product Reference Guide 3. Insert a new cable in the receptacle. Press the cable firmly into the receptacle until you hear a click. Connecting to a Host Plug the connector at the end of the LS 2100 cable into the appropriate port on the Symbol interface controller or portable terminal. Refer to the controller user documentation for full details. LS 2100 Interface Controller Portable Data Terminal LS 2100 Figure 1-3.
Chapter 2 Scanning with the LS 2100 Introduction This chapter covers the proper techniques for scanning bar codes and the decode zone for the LS 2100 scanner. Scanning with the LS 2100 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: " You hear a beep.
LS 2100 Product Reference Guide Figure 2-1. Holding the Scanner Aiming the Scanner Hold the scanner at an angle. Do not hold the scanner directly over the bar code. Laser light reflecting directly back into the scanner from the bar code is known as specular reflection. This strong light can “blind” the scanner and make decoding difficult. The area where specular reflection occurs is known as a “dead zone”. You can tilt the scanner up to 55 ° forward or back and achieve a successful decode.
Scanning with the LS 2100 ! Scan the Entire Symbol " The scan beam must cross every bar and space on the symbol (as in the left bar code below). " The larger the symbol, the farther away you should hold the scanner. " Hold the scanner closer for symbols with bars that are close together. Right Wrong What Does The Beep Mean? When you hear 1 beep (short high tone) it means data has been decoded successfully. If any other beeps are heard, contact the technical person in charge of scanning.

Chapter 3 Maintenance and Specifications Introduction This chapter covers the appropriate methods for maintaining and the technical specifications for the scanner. Maintenance Cleaning the exit window is the only maintenance required. A dirty window may affect scanning accuracy. ! ! ! ! ! Do not allow any abrasive material to touch the window. Remove any dirt particles with a damp cloth. Wipe the window using a tissue moistened with ammonia/water.
LS 2100 Product Reference Guide ! ! Make sure the symbol is not defaced. Try scanning test symbols of the same code type. If after performing these checks the symbol still does not scan, contact your distributor or call the Symbol Support Center. See page vi for the telephone number.
Maintenance and Specifications Optional Accessories Optional accessories, supplied at extra cost, include additional units of any item listed above and the following items: Description Part Number Hands-free Stand-Free Standing 21-33324-01 Desk-mount Stand 21-33323-01 Technical Specifications Item Description Power Requirements 4.75 to 14 VDC; 99 mA @ 5 VDC Typical Decode Capability Determined by interface controller Decode Depth of Field Maximum typical working distance is 11 in.
LS 2100 Product Reference Guide Item Weight (without cable) Description 5.5 oz. (170 gm) Dimensions: 3-4 Height 6.7 in (167 mm) Width 2.8 in (70 mm) Depth 3.
Maintenance and Specifications LS 2100 Signal Descriptions The following signal descriptions apply to the connection between the scanner and the cable, and are for reference only. Pin Signal Name Function 2 Power This pin is to be connected to the 4.75 to 14 V (4.75 to 14 VDC) power supply. When pin 4 is high, current to operate the scanner is supplied by pin 1,2 (99 mA @ 5 VDC). When pin 4 is at ground potential, current into pin 1 and 2 is less than 50 µA.
LS 2100 Product Reference Guide Pin 8 Signal Name Digitized Bar Pattern Function Output from the scanner is electrically identical to pin 5, providing a series of pulses with widths proportional to the widths of the bar code elements being scanned. A low output represents a bar, and a high output represents a space. The frequency of the pulses depends on the density of the symbol being scanned. . PIN 10 PIN 1 Figure 3-1.
Glossary Aperture The opening in an optical system defined by a lens or baffle that establishes the field of view. ASCII American Standard Code for Information Interchange. A 7 bit-plusparity code representing 128 letters, numerals, punctuation marks, and control characters. It is a standard data transmission code in the U.S. Autodiscrimination The ability of an interface controller to determine the code type of a scanned bar code.
LS 2100 Product Reference Guide Byte On an addressable boundary, eight adjacent binary digits (0 and 1) combined in a pattern to represent a specific character or numeric value. Bits are numbered from the right, 0 through 7, with bit 0 the low-order bit. One byte in memory can be used to store one ASCII character. CDRH Center for Devices and Radiological Health. A federal agency responsible for regulating laser product safety.
Glossary Code Length Number of data characters in a bar code between the start and stop characters, not including those characters. Continuous Code A bar code or symbol in which all spaces within the symbol are parts of characters. There are no intercharacter gaps in a continuous code. The absence of gaps allows for greater information density. Dead Zone An area within a scanner's field of view, in which specular reflection may prevent a successful decode.
LS 2100 Product Reference Guide IEC (825) Class 1 This is the lowest power IEC laser classification. Conformity is ensured through a software restriction of 120 seconds of laser operation within any 1000 second window and an automatic laser shutdown if the scanner's oscillating mirror fails. Intercharacter Gap The space between two adjacent bar code characters in a discrete code.
Glossary Percent Decode The average probability that a single scan of a bar code would result in a successful decode. In a well-designed bar code scanning system, that probability should approach near 100%. Print Contrast Signal Measurement of the contrast (brightness difference) between the bars (PCS) and spaces of a symbol. A minimum PCS value is needed for a bar code symbol to be scannable.
LS 2100 Product Reference Guide Start/Stop Character A pattern of bars and spaces that provides the scanner with start and stop reading instructions and scanning direction. The start and stop characters are normally to the left and right margins of a horizontal code. Substrate A foundation material on which a substance or image is placed.
