Section 1

Introduction and Getting Started

Product Overview

The NFT 2100 Fixed Position Scanner is a miniature, 200 scan per second, CCD barcode reader designed

to be easily incorporated into host equipment. The small physical size makes the scanner easy to

integrate into any hardware design. Durability and reliability are assured.

Advanced microprocessor technology coupled with Opticon’s proven decoding algorithms result in high

speed operation with superior accuracy. The scanner is 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.

The scanner is encased in a compact, rugged, yet lightweight steel enclosure. The compact size permits

installation in the tightest areas 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.

Turn off the power to your PC and connect the scanner to a RS232 communications port. Note: You

must provide +5 Volt DC power to the scanner. If you are using our standard LHA2107RR1S-054, you

can utilize power supply, P/N 32-00907-01, by plugging its connector directly into the power jack on the

DB9 connector. If the power supply is obtained from another source verify that it is identified with the

mark. Turn on the power to the PC.

1) If you are operating in a Microsoft Windows 95/98/ 2000/ XP environment, you can set the

communication parameters using Hyper Terminal as follows:

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

Communications

♦Select Hypertrm.exe to create a New Connection

♦In the Connection Description dialog screen enter a name for the new file, like "Opticon". If

desired, select an Icon. Click OK

♦In the

Connect To

(

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 hyper-terminal 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; then Select

ANSI

for Emulation; the

Back scroll

buffer line can remain at the

default 500

♦Click on the ASCII Setup button. In the ASCII Setup Sending screen, select Line ends with

line feeds and Echo typed locally so that any keyboard commands you input will appear on

your screen. In the ASCII Setup Receiving screen, select Append line feeds to incoming line

ends and Wrap lines that exceed terminal width. Click OK. This returns you to the

Properties Setting. Click OK

2) Your PC and the scanner should now communicate. To verify that the scanner and the PC are

communicating properly, send the following command from your PC keyboard which will request

software settings to be displayed.

Send the command in four keystrokes: <Esc> Z3 <Enter>

Note: Be sure to use capital letters, e.g. “Z3”, not “z3”.

A series of software setting should be displayed, indicating that good communications have

been established

3) A red LED light should be visible. If it is not visible, the scanner may be in a mode that requires

a “Trigger” Command from the PC to activate it. You can exit that mode by sending the

following command from your PC keyboard:

4) The “Trigger” mode will now be deactivated and the red LED light will be continuously

illuminated.

This Quick Start-Up procedure will get you started. However, to best understand the full capabilities of

this scanner, you should read the complete manual.
