Introduction

The Symbol LS4278 scanner combines excellent scanning performance and

advanced ergonomics to provide the best value in a lightweight laser scanner.

Whether used as a hand-held scanner or in hands-free mode in a stand, the

scanner ensures comfort and ease of use for extended periods of time. Before

programming the scanner, scan the appropriate bar code(s), beginning on page 8,

to communicate with the host.

Scanning

Beeper Definitions

The scanner issues different beep sequences and patterns to indicate status. The

table below defines beep sequences that occur during both normal scanning and

while programming the scanner.

Beeper Sequence Indication

Standard Use

Low/medium/high beeps Power up.

High beep A bar code symbol was decoded (if decode beeper is

enabled).

Four long low beeps A transmission error was detected in a scanned symbol.

The data is ignored. This occurs if a unit is not properly

configured. Check option setting.

Five low long beeps Conversion or format error.

Low/high/low beeps ADF transmit error.

High/high/high/low beeps RS-232 receive error.

Parameter Menu Scanning

Long low/long high beeps Input error, incorrect bar code or “Cancel” scanned, wrong

entry, incorrect bar code programming sequence; remain

in program mode.

High/low beeps Keyboard parameter selected. Enter value using bar code

keypad.

High/low/high/low beeps Successful program exit with change in the parameter

setting.

Long low/long high/long low/long

high beeps

Out of host parameter storage space. Scan Set Defaults

on page 8.

Wireless Operation

High/low/high/low beeps Pairing bar code scanned.

Low/high beeps Bluetooth connection established.

LED Definitions

In addition to beeper sequences, the scanner communicates with the user using a

two-color LED display. The table below defines LED colors that display during

scanning and charging.

High/low beeps Bluetooth disconnection event.

Long low/long high beeps Page timeout; remote device is out of range/not powered.

Long low/long high/long low/long

high beeps

Connection attempt was rejected by remote device.

Code 39 Buffering

High/low beeps New Code 39 data was entered into the buffer.

Three long high beep Code 39 buffer is full.

Low/high/low beeps The Code 39 buffer was erased or there was an attempt to

clear or transmit an empty buffer.

Low/high beeps A successful transmission of buffered data.

Host Specific

USB only

Four high beeps Scanner has not completed initialization. Wait several

seconds and scan again.

Scanner gives a power-up beep

after scanning a USB Device Type.

Communication with the bus must be established before

the scanner can operate at the highest power level.

This power-up beep occurs more

than once.

The USB bus may put the scanner in a state where power

to the scanner is cycled on and off more than once. This is

normal and usually happens when the host PC cold boots.

RS-232 only

High beep A <BEL> character is received and Beep on <BEL> is

enabled.

Scanning LED Indication

Green Flash A bar code was successfully decoded.

Charging LED Indication

Green - Slow Continuous Flash Non-critical battery temperature fault.

Green - Fast Continuous Flash Scanner is charging.

Green - Solid Scanner is fully charged.

Amber - Continuous Flash Critical battery temperature fault.

Troubleshooting

Problem Possible Cause Possible Solutions

LED indicates a

battery temperature

fault.

Battery is above or

below normal

operating

temperature.

Do not use the scanner. Move the scanner to a

location within normal operating temperature.

The scanner can remain in the cradle while the

battery warms or cools to normal operating

temperature. Refer to the Product Reference

Guide for more information.

Nothing happens

when the trigger is

pulled.

No power to the

scanner.

Battery may be discharged; charge scanner in

cradle.

Check that battery door is closed

Ensure that end cap to battery chamber is

secured.

Scanner is disabled. Some host interfaces (e.g., Synapse, IBM-468x)

can disable the scanner. If this applies, enable

the scanner via the host interface.

Laser comes on,

but symbol does not

decode.

Scanner is not

programmed for the

correct bar code

type.

Ensure the scanner is programmed to read the

type of bar code scanned.

Refer to the Product Reference Guide for more

information.

Bar code symbol is

unreadable.

Check the symbol to ensure it is not defaced. Try

scanning test symbols of the same bar code type.

Distance between

scanner and bar

code is incorrect.

Move the scanner closer to or further from the bar

code.

Symbol is decoded

but not transmitted

to the host.

Cradle is not

programmed for the

correct host

interface.

Check scanner host parameters or edit options.

Scanner not paired

to host-connected

interface.

Pair the scanner to the cradle (using PAIR bar

code on the cradle).

Interface cable is

loose.

Ensure all cable connections are secure.

Cradle has lost

connection to host. In this exact order: disconnect power supply;

disconnect host cable; wait three seconds;

reconnect host cable; reconnect power supply;

reestablish pairing.

Scanned data is

incorrectly

displayed on the

host.

Scanner is not

programmed to work

with the host.

Ensure proper host is selected.

Check the scanner’s host type parameters or

editing options.

For RS-232, ensure the scanner’s

communication parameters match the host’s

settings.

For a keyboard wedge configuration, ensure the

system is programmed for the correct keyboard

type, and the CAPS LOCK key is off.

Ensure editing options (e.g., UPC-E to UPC-A

conversion) are properly programmed.

Refer to the Product Reference Guide for more

information.

Programming Bar Codes

Following are some frequently used programming bar codes.

Set Defaults

Scan SET DEFAULTS to set all parameters to their default values.

SET DEFAULTS

Scanning Modes

Scan the appropriate bar code below to determine the scanning pattern.

•SINGLE LINE ONLY - No up and down scan line movement (no raster).

•MULTI-LINE SMART RASTER - The scan line begins as a single line and

moves up and down (rasters) when a partial scan of a bar code is detected, or

no bar code is decoded 500 ms after the trigger is pulled.

•MULTI-LINE ALWAYS RASTER (default) - Rastering (up and down scan line

movement) begins immediately.

SINGLE LINE ONLY

MULTI-LINE SMART RASTER

MULTI-LINE ALWAYS RASTER (Default)

NOTE For additional host types, refer to the Symbol LS4278 Product

Reference Guide, p/n 72E-69834-xx, available on the

Symbol LS4278 CD, or on the website:

http://www.motorola.com/enterprisemobility/manuals.

Quick Reference Guide 9

Host Types

If a Synapse cable is used (i.e., part number STIxx-xxxx), the scanner autodetects

the Synapse cable and there is no need to scan bar codes to enable the Synapse

host.

If a USB interface is used, the scanner autodetects the USB and defaults to the

HID keyboard interface. See page 12 to select the IBM hand-held host type.

If a Keyboard Wedge, RS-232, Wand Emulation, Scanner Emulation, or IBM

46XX is used, the appropriate host type must be scanned. Select the appropriate

host type from the bar codes that follow.
