Chapter 2 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.
LS 2106 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 2106 t Scan the Entire Symbol s The scan beam must cross every bar and space on the symbol (as in the left bar code below). s The larger the symbol, the farther away you should hold the scanner. s Hold the scanner closer for symbols with bars that are close together. Right 012345 Wrong 012345 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.

Parameter Menus Set Default Parameter Scanning this bar code returns all parameters to the default values listed in Table 4-1. beginning on page 4-2.
LS 2106 Product Reference Guide Beeper Volume To select a beeper volume, scan the LOW VOLUME or HIGH VOLUME bar code.
Parameter Menus Laser On Time This parameter sets the maximum time decode processing continues during a scan attempt. It is programmable in 0.1 second increments from 0.5 to 9.9 seconds. To set a Laser On Time, scan the bar code below. Next scan two numeric bar codes beginning on page 4-57 that correspond to the desired time on. Single digit numbers must have a leading zero. For example, to set a Time On of .5 seconds, scan the bar code below, then scan the “0” and “5” bar codes.
LS 2106 Product Reference Guide Power Mode This parameter determines whether or not power remains on after a decode attempt. When in low power mode, the scanner enters into a low power consumption mode to preserve battery life after each decode attempt. When in continuous power mode, power remains on after each decode attempt.
Parameter Menus Beep After Good Decode Scan this symbol if you want the unit to beep after a good decode. BEEP AFTER GOOD DECODE Do Not Beep After Good Decode Scan this symbol if you do not want the unit to beep after a good decode. The beeper still operates during parameter menu scanning and indicates error conditions.
LS 2106 Product Reference Guide Transmit “No Read” Message When enabled, if a symbol does not decode, “NR” is transmitted. Any prefixes or suffixes which have been enabled are appended around this message. ENABLE NO READ Do Not Transmit “No Read” Message When disabled, if a symbol does not read, nothing is sent to the host.
Parameter Menus Decode Redundancy Use this parameter to indicate whether the scanner must read a bar code one time (Level 0), two times (Level 1) or three times (Level 2) before decoding it. A higher level of redundancy ensures the accuracy of a decode in, for example, poor quality symbols.
LS 2106 Product Reference Guide Autodiscriminate Response Time This parameter extends the length of time during which the scanner tries to detect which host it is connected to on power up. Note: When connected to an LS 5700/5800, the 5-second option must be used.

LS 2106 Product Reference Guide Decode UPC/EAN Supplementals Supplementals are additionally appended characters (2 or 5) according to specific code format conventions (e.g., UPC A+2, UPC E+2, EAN 8+2). Three options are available. If UPC/EAN with supplemental characters is selected, UPC/EAN symbols without supplemental characters are not decoded.
Parameter Menus Transmit UPC-A/UPC-E Check Digit Scan the appropriate bar code below to transmit the symbol with or without the UPC-A or UPC-E check digit.
LS 2106 Product Reference Guide UPC-A Preamble Three options are given for lead-in characters for UPC-A symbols transmitted to the host device: transmit system character only, transmit system character and country code (“0” for USA), and no preamble transmitted. The lead-in characters are considered part of the symbol.
Parameter Menus UPC-E Preamble Three options are given for lead-in characters for UPC-E symbols transmitted to the host device: transmit system character only, transmit system character and country code (“0” for USA), and no preamble transmitted. The lead-in characters are considered part of the symbol.
LS 2106 Product Reference Guide Convert UPC-E to UPC-A This parameter converts UPC-E (zero suppressed) decoded data to UPC-A format before transmission. After conversion, data follows UPC-A format and be affected by UPC-A programming selections (e.g., Preamble, Check Digit). Scanning DO NOT CONVERT UPC-E TO UPC-A allows you to transmit UPC-E (zero suppressed) decoded data.
Parameter Menus EAN Zero Extend If this parameter is enabled, five leading zeros are added to decoded EAN-8 symbols to make them compatible in format to EAN-13 symbols. Disabling this parameter returns EAN-8 symbols to their normal format.
LS 2106 Product Reference Guide EAN Zero Extend Code Type This parameter allows a decoded EAN-8 symbol that has been converted to EAN-13 to be transmitted with either an EAN-13 code type or an EAN-8 code type.

LS 2106 Product Reference Guide Enable/Disable Code 39 Full ASCII To enable or disable Code 39 Full ASCII, scan the appropriate bar code below. When enabled, the ASCII character set assigns a code to letters, punctuation marks, numerals, and most control keystrokes on the keyboard. The first 32 codes are non-printable and are assigned to keyboard control characters such as BACKSPACE and RETURN. The other 96 are called printable codes because all but SPACE and DELETE produce visible characters.
Parameter Menus Code 39 Buffering (Scan & Store) When you select the scan and store option, all Code 39 symbols having a leading space as a first character are temporarily buffered in the unit to be transmitted later. The leading space is not buffered. Decode of a valid Code 39 symbol with no leading space causes transmission in sequence of all buffered data in a first-in first-out format, plus transmission of the “triggering” symbol. See the following pages for further details.
LS 2106 Product Reference Guide Buffer Data To buffer data, Code 39 buffering must be enabled, and a symbol must be read with a space immediately following the start pattern. t t t Unless symbol overflows the transmission buffer, the unit gives a lo/hi beep to indicate successful decode and buffering. See Overfilling Transmission Buffer. Unit adds the message, excluding the leading space to the transmission buffer. No transmission occurs.
Parameter Menus Transmit Buffer To transmit the buffer, read a symbol containing either the first or second condition: 1. Only a start character, a plus (+), and a stop character. s The unit signals that the transmission buffer has been sent (a lo/hi beep). s Unit sends the buffer. s Unit clears the buffer. TRANSMIT BUFFER 2. A Code 39 bar code with leading character other than a space. s The unit signals a good decode and buffering of that decode has occurred by giving a hi/lo beep.
