Chapter 3 A–B Using the Scanner Chapter Objectives This chapter covers some basic topics on the operation and use of the scanner including: • • • • • • • • Physical Description Physical Description LED Indicators Safety Labels Scanning Ranges Operating Scanner Beep Operating Tips Troubleshooting The scanners use a low power visible laser diode light source for non-contact scanning applications. The trigger in the handle of the scanner turns on the light beam.
Chapter 3 Using the Scanner Light, reflected off the bar code symbols, passes back through the window and is detected by light sensors. When a label is read, the laser is automatically turned off until the next pull of the trigger. The laser beam looks like a narrow red line of light. It is actually a tiny spot of light traveling very fast. The laser spot moves across the bar code symbol at approximately 35 scans/second. The bar code is scanned many times in a short period of time.
Chapter 3 Using the Scanner Safety Labels The scanners use a low power visible laser diode. As with any bright light source, such as the sun, you should avoid staring directly into the beam. Momentary exposure to a CDRH Class II laser is not known to be harmful. The following figure shows the location of all safety labels as they appear on the scanner. CAUTION: ! Use of controls, adjustments, or performance of procedures other than those specified herein may result in hazardous visible light exposure.
Chapter 3 Using the Scanner Scanning Ranges The scanners can read bar code labels at various distances depending on the bar code width (width of narrowest element in bar code, either bar or space). Table 3.B defines the scanning ranges for both the standard and long range scanner. Scanning ranges are listed for symbols with bar code widths from 6.0 mil to 55.0 mil (.15 mm to 1.40 mm). Table 3.B Scanning Ranges: Standard and Long Range Scanners Bar Code Width 6.0 mil (.15 mm) 7.5 mil (.19 mm) 10.0 mil (.

To remove the interface cable, follow these steps. 1. Turn power to computer/terminal off. 2. Disconnect optional power supply from AC power source. 3. Disconnect scanner from wedge interface cable. 4.
Chapter 4 Setup Instructions Connecting Wedge Interface Cable The wedge interface cable connects the scanner to the terminal keyboard and the terminal. You select a wedge interface cable based on the the terminal you are using. The available cables are listed in Table 2.A. The wedge interface cable has a connector housing and a ”Y” cable. The housing contains 1 or 2 plug-in sockets for the scanner and an optional power supply. The two legs of the ”Y” cable connect to the terminal keyboard and the terminal.
Chapter 4 Setup Instructions Connecting Optional Power Supply Some terminal interfaces require an external power supply. One end connects to a standard AC receptacle supplying the appropriate voltage level. The other end plugs into a receptacle located on the housing connector of the wedge interface cable. CAUTION: ! The Catalog No. 2755-PW1 Power Supply has the following polarity: +5 V + Ground If using another power supply, the polarity must be the same. To install the power supply: 1.
Chapter 4 Setup Instructions Enabling Wedge Mode After installing the keyboard wedge interface you need to enable the scanner to operate in wedge mode. If this is a first time installation you must enable the scanner to operate in wedge mode. To enable wedge mode, scan label CE and listen for two short beeps. CE Selecting a Terminal Type Enable Wedge Mode * You now need to identify the type of terminal that the wedge interface is connected to.
Chapter 4 Setup Instructions CH CI IBM 3151, 3472 DEC VT220 VT240, VT320, VT340, VT420, VT1000 You have now completed the process of installing and configuring the scanner to operate in wedge mode. The rest of the manual covers additional parameters that can be set for the scanner and your application. Review the configuration guidelines and factory default settings in the following sections to determine if changes are required.
Chapter 4 Setup Instructions Scanner Configuration Guidelines Configuration is the process of enabling or disabling certain scanner operating parameters. The host computer/terminal and the types of bar codes that will be encountered will determine which parameters should be enabled or disabled. Follow three basic steps to configure your scanner: 1. Review the rest of the manual to familiarize yourself with each group of scanner parameters. 2.
Chapter 4 Setup Instructions Note: When enabling or disabling a parameter, be sure the scanner beam illuminates only one symbol at a time. The layout of this manual minimizes the accidental scanning of multiple labels. Some parameters require that you scan multiple labels to modify a setting. An example is the Intercharacter Delay parameter. To set the intercharacter delay to 5 milliseconds (msec): 1. Scan the Intercharacter Delay (GB) label and listen for one short beep.

Chapter 5 General Setup Parameters Power Consumption You can select one of two power consumption modes for the scanner. Option @A supplies full power to the scanner at all times. Option @B allows the scanner to revert to standby mode after a successful read. This mode is a power conservation feature whereby the scanner uses extremely low power (microwatts) from the host terminal. To supply full power to the scanner at all times, scan label @A.
Chapter 5 General Setup Parameters Beeper Operation To disable or set the volume of the beeper, scan the appropriate option below.
Chapter 5 General Setup Parameters Capture Count Capture Count determines the number of successful, identical decodes that must occur for a valid read. You can use the capture count to enhance the security of the bar code reader. Option BC sets the capture count to 1 which requires one successful decode. BC Capture Count = 1 * Scan option BD to set the capture count to 2. Two identical decodes must occur for a valid read.
Chapter 5 General Setup Parameters Spotter Beam You can enable the scanner to use a spotter beam which helps when aiming the scanner. Each time you press the trigger, the scanner generates a bright laser spot for a fixed duration, after which the scanner beam is activated. The spotter beam is recommended for long range applications. Scanning label NP disables the spotter beam. Hold the trigger for two seconds after scanning.
Chapter 5 General Setup Parameters Autosense Mode In Autosense mode, the scanner has an internal object sensor allowing you to operate the scanner in an optional Autostand (Catalog No. 2755-NS2) for hands-free operation. When the scanner is placed in the Autostand it becomes immediately active for reading any bar code label presented to it. The scanner is triggered when a bar code label breaks the scan beam path between the reflective label on the stand and the scanner.
Chapter 6 A–B Message Format Parameters Chapter Objectives This chapter defines parameters that control the format of transmitted bar code messages including: • • • • Prefix and Suffix Scanner Identifier Code Identifier Preamble and Postamble In addition to these parameters, you can program an intercharacter delay to prevent data overruns with your host computer/terminal or wedge.
Chapter 6 Message Format Parameters Prefix A prefix is a subset of the preamble normally formatted to some industry standard. It is represented by a specific ASCII code. An example of a prefix is the STX (Start of Transmission) code. Scan the appropriate prefix label.
Chapter 6 Message Format Parameters Suffix A suffix is a subset of the postamble. Like the prefix, it is normally assigned to a specific ASCII code. Examples of suffixes are CR (Carriage Return) and LF (Line Feed). Scan the suffix appropriate for your application.
Chapter 6 Message Format Parameters Scanner Identifier Scanner ID characters are used to identify individual scanners when more than one scanner is interfaced with the host system. Options available are none (Disabled) or digits 01 through 99. Scanning label JA disables the scanner identifier.
