Introduction and Getting Started

Product Overview

The NLB-9625/9645 Series Fixed Position Scanners are miniature, 33 or 200 scans per second, laser bar code

readers designed to be easily incorporated into host equipment. Utilizing a solid state laser diode and a

brushless motor results in a minimum of wear on parts and high performance. The scanner is encased in a

rugged steel enclosure to assure durability and reliability.

Advanced 16-bit microprocessor technology coupled with Opticons proven decoding algorithms result in

superior accuracy. The scanners are fully programmable allowing the user to customize parameters including

changing communication settings, selecting symbologies, adding prefixes and appending suffixes.

Programmable settings can be downloaded from the host CPU or computer directly to the scanner.

NLB 9625/9645 Series laser scanners are encased in compact, rugged steel enclosures. The compact size

permits installation in the tightest areas. Scanners are available in both front and side view configurations

allowing great flexibility in mounting and positioning the scanner for optimum performance.

Quick Start-Up Procedure

This section is for those who wish to start using the scanner before reading the complete manual. In only a few

steps the scanner will be operable.

1) Turn off the power to your PC and connect the scanner to an RS232 communications port. Note: You must

provide +5 Volt DC power to the scanner. This can be accomplished using the power supply and patch cable

available from Opticon. Turn on the power to the PC.

2) Using communications software (e.g., Procom), set the communication parameters: 9600 baud, 1 Start /

Stop Bit, 8 Data Bits, No Parity, No Handshaking, No Flow Control.

3) If you are operating in a Microsoft Windows 3.1 environment, skip to Step 5.

4) If you are operating in a Microsoft Windows 95 environment, you can set the communication

parameters using Hyper Terminal as follows:

♦Open Hyper Terminal. This can be done from Start→Programs→Accessories

♦Select Hypertrm.exe to create a New Connection.

♦In the Connection Description dialog screen enter a name for the new file. If desired, select an

Icon. Click OK.

♦In the Phone Number dialog screen, in the box entitled: Connect using. select the communication

port, for example, Direct to Com 1. Click OK.

♦In the Com 1 Properties screen, enter the appropriate Port Settings:

Bits per second = 9600

Data bits = 8

Parity = None

Stop Character = 1

Handshaking = None

Click OK.

♦The HyperTerminal folder you just created will open. From the File pull-down menu, select

Properties, then click on the Setting Tab.

♦In the Properties Settings dialog screen:

Select Terminal keys for the Function, arrow and control key

Select ANSI for Emulation,

The Backscroll buffer line can remain at the default 500

♦Click on the ASCII Setup button. In the ASCII Setup screen, select Echo typed locally so that any key-

board commands you input will appear on your screen. Click OK. This returns you to the Properties

Setting. Click OK.

Your PC and the scanner should now communicate. Skip to Step 6.

5) In a Microsoft Windows 3.1 environment, set the communication parameters using the Terminal func-

tion of Windows.

♦From Windows Program Manager Main Menu, select Terminal

♦From the Terminal menu, select Settings

♦From the Settings menu, select Terminal Emulation

♦Set the emulation to TTY (generic)

♦From the Settings menu, select Terminal Preferences and select the following:

Terminal Modes: Line Wrap / Local Echo / Sound

CR /LF: Inbound, Outbound

Columns: 80

♦From the Settings menu, select Communications.

♦Select the COM port and set communication parameters as shown in Step 2, including no flow

control.

6) To verify that the scanner and the PC are communicating properly, send the following command from

your PC keyboard to activate the scanners buzzer.

Send the command: <Escape> V5 <Carriage Return>

Note: Be sure to use capital letters (e.g. V5, not v5).

The buzzer should sound, indicating that good communications have been established.

7) A red laser light should be visible. Do not stare into the laser light. If the light is not visible, the scanner

may be waiting for a Trigger Command from the host to activate it. Send the following computer com-

mand to place the scanner into the Triggered Disabled mode:

In this Triggered Disabled mode, the red laser light is always illuminated. You are now ready to scan

barcodes.

8) Position the red laser light of the scanner over the bar code symbol to be read. When the bar code

symbol is decoded, the scanner will beep and transmit the data to the screen of your PC. You may have

to move the scanner closer or farther away from the bar code symbol in order to locate the best distance

for reading.

This Quick Start-Up procedure will get you started reading bar code symbols. However, in order to best

understand the full capabilities of this scanner, you should read the complete manual.
