Servi ce In forma tion

If you have a problem with your equipment, contact the Symbol Support Center. Before
calling, have the model number , serial number , and several of your bar code symbols at hand.

Call the Support Center from a phone near the scanning equipment so that the service person
can try to talk you through your problem. If the equipment is found to be working properly
and the problem is symbol readability, the Support Center will request samples of your bar
codes for analysis at our plant.

If your problem cannot be solved over the phone, you may need to return your equipment for
servicing. If that is necessary, you will be given specific directions.

Setting Up the LS 2104

Introduction

The LS 2104 hand-held laser scanner off ers excellent pe rfor man ce in retail an d light
industrial applications. Advanced ergonomic design ensures comfortable use for extended
periods of time.

The LS 2100 Series of hand-held scanners are based on the SE 1200 Series scan engine with
Visible Laser Diode (VLD) and mylar
the scanner a wider decode zone, greater depth of field, and a visible scan beam. This model
reads color bar codes and symbols printed on all substrates. See the LS 2104 Decode Zone
on page 2-4.

Here’s what each member of the LS 2100 family offers you:

LS 2106 - The LS 2106 scanner is a keyboard “wedge” interface which adds efficient,
reliable bar code reading to your PS/2 and AT/XT terminal. Since entered scan data
is transmitted as keystrokes, no software changes to the host system are necessary.
The scanner contains on-board discrete keyboard wedge communications for
connecting to asynchronous terminals and host systems. It can also accommodate
any of the Synapse™ “Smart Cables” which allows you to connect to a wide variety
of host systems. Some installations require one cable; others require additional
adapters between the keyboard, the PC, and the y-cable.

All of the LS 2100 series scan automatically at the rate of 36 scans per second. For decode
capability, see Technical Specifications on page 3-4.

Scanning with the LS 2104

Introduction

This chapter covers the proper techniques for scanning bar codes and the decode zone for the
LS 2104 scanner.

Scanning with the LS 2104

Before you can use the scanner, it should have already been installed and programmed. If not,
see Chapter 4, Paramet er Men us for instructions on programming your scanne r. If you need
assistance, contact your local supplier or Symbol Technologies.

1. Before you use the scanner, make sure all cable co nnections 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.
" The orange light turns green.
" The red laser turns off.

2-1

LS 2104 Product Reference Guide

Figure 2-1. Holding the Scanner

Aiming the Scanne r

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. Simple
practice quickly shows wh at tolerances to work within.

2-2

Scanning with the LS 2104

!

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.

When the symbol has been decoded successfully, you will hear a short, high-tone beep, and
the green decode LED will light.

For more specific information on the meanings of the various beeper sounds, refer to Beeper
Indications on page 3-8.

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 mainte nance required. A dirty window may affect
scanning accuracy.

!

Do not allow any abrasive material to touch the window.

!

Remove any dirt particles w ith a da mp cl ot h.

!

Wipe the window using a tissue moistened with ammonia/water.

!

Do not spray water or other cleaning liquids directly into the window.

!

Do not remove the nose of the scanner.

Troubleshooting

If, after following the opera ting instructions, the scanner does not work:

!

Check the system power.

!

Make sure the controller is programmed to decode bar codes of the symbology you
are scanning.

!

Check for loose cable connections.

3-1

LS 2104 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 x for the telephone number.

Introduction

The LS 2104 is shipped with the settings shown in the Default Parameters begin ning on pa ge
4-2. These default values are stored in non-volatile memory and are preserved even when the
scanner is powered down. You can change these default values by scanning the appr opr iat e
bar codes included in this manual. These new values replace the standard default values in
memory . The default parameter values can be recalled by scanning the SET ALL DEFAUL TS
bar code on page 4-5.

The scanner automatically identifies the host type on power-up. It makes this determination
provided the host is powered-up before the scanner is attached to it.

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.

Code 39 Full ASCII interprets the bar code special character ($ + % /) preceding a Code 39
character and assigns an ASCII ch ar acter val ue to the pair. For example, when Code 39 Full
ASCII is enabled and a +B is scanned, it is interpreted as b, %J as ?, and $H emulates the
keystroke BACKSPACE. Scanning ABC$M outputs the keystroke equivalent of ABC
ENTER.

The scanner does not autodiscriminate between Code 39 and Code 39 Full ASCII.

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.

When the scan and transmit option is selected, decoded Code 39 symbols without leading
spaces are transmitted without bei ng stored in the buffer.

Scan and Store affects Code 39 decodes only . If you select scan and store, we recommend that
you configure the scanner to decode Code 39 symbology only.

BUFFER CODE 39

(ENABLE)

DO NOT BUFFER CODE 39

(DISABLE)

While there is data in the transmission buffer, deleting Code 39 buffering capability via
the parameter menu is not allowed. The buffer holds 200 bytes of information.

T o allow disabli ng of Code 39 buffering, first force the buffer transmission (see Transmit
Buffer) or clear the buffer . Both the CLEAR B UFFER and TRANSMIT BUFFER bar codes
are length 1. Be sure Code 39 length is set to include length 1.

Hardwar e Handshaking

The data interface consists of an RS-232C port. The port has been designed to operate either
with or without the hardware handshaking lines, Request to Send (RTS), and Clear to Send
(CTS).

If Standard RTS/CTS handsha king is selected, scan data is transmit t e d according to the
following sequence:

!

The controller reads the CTS line for activity. If CTS is asserted, the controller waits
up to 2 seconds for the host to negate the CTS line. If, after 2 seconds (default), the
CTS line is still asserted, the scanner sounds a transmit error and any scanned data
is lost.

!

When the CTS line is negated, the controller assert s the RTS line and waits up to 2
seconds for the host to assert CTS. When the host asserts CTS, data is transmitted.
If, after 2 seconds (default), the CTS line is not asserted, the scanner sounds a
transmit error and discards the data.

!

When data transmission is complete, the controller negates RTS 10 msec after
sending the last character.

!

The host should respond by negating CTS. The controller checks for a negated CTS

upon the next transmission of data.

During the transmission of data, the CTS line should be asse rted. If CTS is deasserted for
more than 50 ms between characters, the transmission is aborted, the scanner sounds a
transmission error, and the data is discarded.

If the above communications sequence fails, the scanner issues an error indication. In this
case, the data is lost and must be rescanned.

If Hardware Handshaking and Software Handshaking are both enabled, Hardware
Handshaking takes precedence.

The DTR signal is jumpered active.

Note:

4-58

Parameter Menus

Scan the bar code below if no Hardware Handshaking is desired.

NONE

Scan the bar code below to select Standard RTS/CTS Hardware Handshaking.

STANDARD RTS/CTS

When RTS/CTS Option 1 is selected, the scanner asserts RTS before transmitting and ignores
the state of CTS. The scanner deasserts RTS when the transmission is complete.

RTS/CTS OPTION 1

4-59

LS 2104 Product Reference Guide

When Option 2 is selected, RTS is always high or low (user-programmed logic level).
However, the scanner waits for CTS to be asserted before transmitting data. If CTS is not
asserted within 2 seconds (defaul t), the scanner iss ues an erro r indicat ion and dis car ds th e
data.

RTS/CTS OPTION 2

When Option 3 is selected, the scanner asserts RTS prior to any data
transmission, regar dle ss of the state of CTS. The sca nner waits up to 2 seconds
(default) for CTS to be asserted. If CTS is not asserted during this time, the
scanner issues an error indication and discar ds the data. The scanner deasserts
RTS when transmission is complete.

Parameter Menus

Software Handshaking

This parameter offers contro l of the dat a transmis sion process in addition to, or instead of,
that offered by hardware handshaking. Ther e are five options.

If Software Handshaking and Hardware Handshaking are both enabled, Hardware
Handshaking takes precedence.

None

When this option is selected, data is transmitted immed iately.

NONE

ACK/NAK

When this option is selected, after transmitting data, the scanner expects either an ACK or
NAK response from the host. Whenever a NAK is received, the scanner transmits the same
data again and waits for either an ACK or NAK. After three unsuccessful attempts to send
data when NAKs are received, the scanner issues an error indication and discards the data.

The scanner waits up to the programmable Host Serial Response Time-out to receive an ACK
or NAK. If the scanner does not get a response in this time, it issues an error indication and
discards the data. There are no retries when a time-out occurs.

ACK/NAK

ENQ

When this option is selected, the scanner waits for an ENQ character from the host before
transmitting data. If an ENQ is not received within 2 seconds, the scanner issues an error
