Installation

Quick Installation Outline

The following is a quick preview of the steps required for first time installations. Each item is discussed in

detail later in this section.

• Determine clearance, ventilation, and service access requirements.

• Determine checkout counter layout taking into account package flow, cable routing, and power

requirements.

• Choose the mounting option which provides the best cable/power access and unit stability.

• Unpack the unit.

• Make the appropriate countertop cutouts and install all support brackets.

• Place the unit in the counter.

• Install the platter.

• Follow the steps under the correct interface to connect the cables and power supply.

• Configure the unit for the correct interface.

Site Requirements

Before installing your MS2421/MS2422/MS2431 bar code scanner, please consider the following items.

Vertical Clearance

A minimum clearance height of 5.25" from the checkout counter surface is needed for the vertical 'hood' on

all of the scanner models.

Ventilation and Spacing

The MS2421/MS2422/MS2431 models have a die-cast housing to dissipate heat allowing the unit to

operate without a ventilation fan. The temperature surrounding the unit is recommended not to exceed

40°C (104°F). There should be adequate convection and minimal heat producing equipment in close

proximity of the unit. A cooling fan with a filter is recommended if there will be a conveyor motor or other

heat producing equipment close to the unit that will create a high temperature environment.

Service Access

When routing and installing the cable(s) and power supply, make sure you leave access so that these

components may be swapped easily without the need to remove the unit from the checkout counter.

When changing the StratosSWAP optics engine modules, removing the unit completely from the checkout

counter is recommended.

Site Requirements

Power Installation

The Power Supply (AC/DC) should be connected to an AC Outlet that is free of electrical noise (clean). A

qualified electrician can determine the amount of electrical noise on the AC line. See additional information

on power installation and restrictions under the Installation: Interface section of this manual.

Note: Using a switched AC outlet is recommended. The switch should be located on the operator’s side

of the checkout counter in close proximity to the scanner to facilitate service of the unit.

Checkout Counter Layout Considerations

When placing a scanner in a checkout counter, the following factors should be considered:

• Items should flow at a distance to the operator that maximizes comfort. The operator should not

need to stretch or strain to reach for and scan packages.

• The MS2421/MS2422/MS2431 can scan a bar code on five sides of a package. The packages

should flow into the scan area that provides the maximum reading performance. No lifting or

orientation of the items is necessary. A properly placed item diverter can maximize the flow of

packages.

• In what direction are the packages flowing? Most checkout counters are designed for left-handed

takeaway. If the operator is facing the vertical window of the scanner, packages flow from the

operator's right to left. The packages are in queue on the conveyor to the right and the bagging is

to the left.

Unpacking the Unit

1. Make sure the shipping box is topside up before

opening.

2. Remove the accessories box and check the box’s

content for the following items.

 Product Manuals

 Power Supply

 Communication Cables

 Remote Scale Display (Optional)

3. Carefully remove the platter and store it in a safe

location until the unit is properly installed into the

checkout counter.

4. Lift the scanner out of the box by carefully grasping

both sides near the center of the unit and lifting

directly up. Refer to Figure 15 for hand placement.

Important! Do not remove the scanner from the

box by grabbing the shipping foam.

This can result in the unit falling!

5. Carefully remove the shipping foam from around

the scanner.

Cable Installation (Interface Specific)

RS232

The following steps describe how to properly install the cables for an RS232 application. The scanner

must then be configured to match the host’s RS232 parameters. Cable installation alone does not

guarantee that the scanner will communicate properly with the host system.

Note: Configuration bar codes are located in the MetroSelect Configuration Guide (PN 00-02407x) and

the MS2xxx Stratos Series Configuration Addendum (PN 00-02034x).

1. Turn off the host system.

2. Plug the 10-pin RJ45 end of the RS232 interface cable (PN 57-57210x-N-3) into the 10-pin socket

labeled ‘Scanner Host RS232’ on the bottom of the scanner. Refer to the figure on page 23.

3. Connect the other end of the RS232 cable to the proper communication port on the host device.

Stop: Before continuing, verify that the RS232 interface cable is connected to the appropriate

interface socket on the scanner. An incorrect cable connection can cause communication

problems or potential damage to the scanner and/or terminal.

4. Plug the external power supply (PN 46-002xx) into the 3-pin Molex socket labeled ‘DC Power In’ on the

bottom of the scanner.

Note: Check the AC input requirements of the power supply to make sure the voltage matches the

AC outlet. The outlet should be located near the equipment and be easily accessible.

Using a switched AC outlet is recommended. The switch should be located on the

operator’s side of the checkout counter in close proximity to the scanner to facilitate

calibration and service of the unit.

5. Connect AC power to the transformer. If the AC outlet is equipped with an on/off switch, turn the power

on.

Note: Configuration bar codes are located in the MetroSelect Configuration Guide (PN 00-02407x) and the

MS2xxx Stratos Series Configuration Addendum (PN 00-02034x).

1. Turn off the host system.

2. Plug the 10-pin RJ45 end of the RS485 interface cable (PN 57-57212x-N-3) into the 10-pin socket

labeled ‘Scanner Host 46xx’ on the bottom of the scanner. Refer to the figure on page 27.

3. Connect the other end of the RS485 cable to communication port 9 on the host device.

Stop: Before continuing, verify that the RS485 cable is connected to the appropriate interface

socket on the scanner. An incorrect cable connection can cause communication problems

or potential damage to the scanner and/or terminal.

Note: Plugging the scanner into the serial port of the host device does not guarantee that scanned

information will appear at the host device. A software driver and correct configuration

settings are also required for proper communication to occur.

4. Plug the external power supply (PN 46-002xx) into the 3-pin Molex socket labeled ‘DC Power In’ on the

bottom of the scanner.

Note: Check the AC input requirements of the power supply to make sure the voltage matches the

AC outlet. The outlet should be located near the equipment and be easily accessible.

Using a switched AC outlet is recommended. The switch should be located on the

operator’s side of the checkout counter in close proximity to the scanner to facilitate

calibration and service of the unit.

5. Connect AC power to the transformer. If the AC outlet is equipped with an on/off switch, turn the power

on.

6. Turn on the host system.

7. Configure the scanner to match the host system’s RS485 parameters.

Note: Refer to the MS2xxx Stratos Series Configuration Addendum (PN 00-02034x) under

Scanner Configuration Bar Codes: IBM 3rd Generation Communication Defaults and IBM

3rd Generation Protocols.

Cable Installation (Secondary Honeywell Scanner)

The following steps describe how to properly install the cables between a secondary Honeywell scanner

and the MS2421/MS2422/MS2431 scanner. The MS2421/MS2422/MS2431 and the secondary scanner

must then be configured to communicate properly. Cable installation alone does not guarantee that the

MS2421/MS2422/MS2431 scanner will communicate properly with the host system and secondary

scanner.

Note: Contact a customer service representative before connecting another manufacturer’s scanner to the

MS2421/MS2422 as a secondary scanner.

Configuration bar codes are located in the MS2xxx Stratos Series Configuration Addendum

(PN 00-02034x) under Scanner Configuration Bar Codes: Auxiliary Port, Quick Start for a

Secondary Honeywell Scanner.

1. Refer to pages 22 - 26 for the type of interface (RS232, RS485, etc.) required for your application.

Follow the cable installation steps under the appropriate interface before continuing. Once the

communication and power cables have been installed follow step 2 below for the secondary scanner

installation.

2. Connect the straight end of the RS232 PowerLink AUX cable (PN 57-57099x-3 or PN 57-57099x-3-12)

into the RS232 socket of the secondary scanner (see the figure on page 29).

3. Connect the angled end of the RS232 AUX cable (PN 57-57099x-3 or PN 57-57099x-3-12) into the 10-

pin socket labeled

‘Aux RS232 In’, on the bottom of the MS2421/MS2422/MS2431 scanner.

Note: The MS2421/MS2422/MS2431 series’ aux port requires the signals; transmit, receive, RTS

& CTS from the secondary scanner.

For Rev G Units or later: The MS2420/MS2430’s auxiliary port will support 5VDC devices with a

700mA maximum current.

For Rev F units or earlier: The MS2420/MS2430’s auxiliary port will support 5VDC devices with a

150mA maximum current. If the auxiliary device exceeds this

specification, an external power supply will be required to power the

auxiliary device. The following Honeywell scanners can receive power

from MS2420/MS2430: the MS9520, MS9540, and the MS5145.

4. This step is required for secondary devices that require >5VDC and/or 700mA current to

operate. Skip to step 5 if the secondary device requires ≤ 5VDC.

Plug the power supply into the secondary scanner’s PowerLink cable (PN 57-57099x-3 or

PN 57-57099x-3-12)) and connect AC power to the secondary scanner.

Note: Check the AC input requirements of the power supply to make sure the voltage matches the

AC outlet. The outlet should be located near the equipment and be easily accessible.

5. Configure the MS2421/MS2422/MS2431 scanner and the secondary scanner. The auxiliary input

port’s data format must match the main output format of the secondary scanner.

Note: Refer to the MS2xxx Stratos Series Configuration Addendum (PN 00-02034x) under

Wake Activation Area (Photocell LED Output)

The MS2421/MS2422/MS2431 scanner’s default power save mode†

is Dual Action Power Save Mode #2

(see page ). This power save mode turns the laser OFF after a configured period of non-use then turns

the motor OFF after thirty-minute intervals. Any movement detected by the photocell in the activation area,

shown below in grey, will cause the scanner to exit the power save mode. The motor will restart

automatically and the laser will turn back on preparing the scanner for bar code recognition, decoding, and

transmission.

Audible Indicators

When in operation, the MS2421/MS2422/MS2431 scanner provides audible feedback that indicates the

status of the unit and the current scan. Eight settings are available for the tone of the beep (normal, six

alternate tones and no tone) plus three volume settings. To change the tone or volume, refer to the

Changing the Beeper Tone and Volume section of this manual.

One Beep

When the scanner first receives power, the blue LED will turn on and the scanner will beep once. The

scanner is now ready to scan.

When the scanner successfully reads a bar code, the blue LED will flash and the scanner beeps once (if

configured to do so). If the scanner does not beep once and the blue light does not flash, then the bar

code has not been successfully read.

Razzberry Tone

This is a failure indicator. Refer to failure modes on page 37.

Three Beeps - during operation

When placing the scanner in configuration mode, the blue LED will flash while the scanner simultaneously

beeps three times. The blue LED will continue to flash until the unit exits configuration mode. Upon exiting

configuration mode, the scanner will beep three times and the blue LED will stop flashing.

When configured, three beeps can also indicate a communications timeout during normal scanning mode.

When using one-code-configuring, the scanner will beep three times (the current selected tone), followed

by a short pause, a high tone, and a low tone. This tells the user that the single configuration bar code has

successfully configured the scanner.

Three Beeps - on power up

This is a failure indicator. Refer to failure modes on page 37.

Descending Tone

The scanner will emit a descending tone when the microprocessor is about to Flash upgrade.

Ascending Tone

The scanner will emit an ascending tone when the interface coprocessor is about to Flash upgrade.

Figure 32. Blue LED

Visual Indicators

Blue LED is located near the bottom corner of the

vertical output window. When the scanner is ON, the

flashing or constant illumination of the LED indicates

the status of the scanner and the current scan.

No Blue LED

The blue LED will not be illuminated if the scanner is

not receiving power from the host or transformer.

They are also not illuminated when all lasers are turned

off.

Steady Blue

When all lasers are active, the blue LED is illuminated.

The blue LED will remain illuminated until all lasers are

deactivated.

Steady Blue and Single blue Flash

When the scanner successfully reads a bar code, the blue LED will flash and the scanner will beep once. If

the blue LED does not flash or the scanner does not beep once, then the bar code has not been

successfully read.

Blue LED Off

After a successful scan, the scanner transmits the data to the host device. Some communication modes

require that the host inform the scanner when data is ready to be received. If the host is not ready to

accept the information, the scanner’s blue LED will remain off until the data can be transmitted.

This indicates the scanner may be waiting for communication from the host.

Flashing Blue

This indicates the scanner is in program mode. A razzberry tone indicates that an invalid bar code has

been scanned in this mode.

If the unit is in sleep mode, the blue LED will flash once every 15 seconds.

This indicates there is an error active on the diagnostic indicator display (see Error Codes on page 38).

The scanner may continue to operate depending on the type of error.

Failure Modes

Flashing Blue and One Razzberry Tone

This indicates that the scanner has experienced a laser subsystem failure. The scanner will try up to three

times to correct the failure condition. If the laser subsystem continues to fail, that subsystem (horizontal or

vertical) will be shut down and an error indication will be shown on the Diagnostic Indicator Display. This

error stays on the display until corrected. If the remaining subsystem is still operational, scanning will

continue using the operational components.

Flashing Blue and Two Razzberry Tones

This indicates that the scanner has experienced a motor subsystem failure. The scanner will try up to three

times to correct the failure condition. If the motor subsystem continues to fail, that subsystem (horizontal or

vertical) will be shut down and an error indication will be shown on the Diagnostic Indicator Display. This

error stays on the display until corrected. If the remaining subsystem is still operational, scanning will

continue using the still operational components.

Continuous Razzberry Tone with Blue LED Off

If, upon power up, the scanner emits a continuous razzberry tone, then the scanner has an electronic

failure. Return the unit for repair at an authorized service center.

Three Beeps - On Power Up

If the scanner beeps three times on power up then, the nonvolatile memory that holds the scanner

configuration has failed. Return the unit for repair at an authorized service center.

Diagnostic Indicator Display

There is a two-digit error code display located under horizontal output window near the top of the platter

(see figure below).

Figure 33. Error Code Display

The following is a list of possible error codes and their meanings. Some errors will require immediate

scanner maintenance.

Error

Code

Description

01 Reserved

02 RAM ERROR – The scanner’s Random Access Memory (RAM) is tested as faulty. Return the

unit for repair at an authorized service center.

03 PROGRAM ERROR – The scanner’s software program is failing. Return the unit for repair.

INTERFACE ERROR – After power up and any application exit (e.g. MetroSet, etc.), the

scanner checks the interface hardware with that chosen in configuration. If they do not agree,

an interface error exists. Correct this problem by getting the proper hardware interface OR

programming MS2421/MS2422/MS2431 configuration for the proper interface hardware

attached.

CONFIGURATION ERROR – The non-volatile configuration memory did not agree with the

data last saved. Default configuration data is then used and the scanner continues operating.

This error is also accompanied by three beeps. This error will remain during operation as a

reminder that this power cycle is scanning against a default-generated configuration.

COMMUNICATION ERROR – The RS232 data line is being held active. This causes the

scanner to read a “break” signal constantly and continuous attempts are made to enter

MetroSet configuration mode. A short on the RX Data line can cause this condition. It can

also be the result of a laptop in power save mode. The scanner will abort attempts to enter

configuration mode after a short timeout. The scanner can automatically recover from this

condition once the short in the RX Data line is corrected.

Error

Code

Description

COPROCESSOR COMMUNICATION ERROR – The main microprocessor is not

communicating with the interface coprocessor. The interface coprocessor may be in a fault

condition with the host or just not able to respond. This error may appear when the scanner is

configured for USB or RS485 interface applications or during an attempt to update the

interface software through the flash utility. The unit should be repaired at an authorized

service center.

SWITCH ERROR – The switch used for volume selection or sleep mode is detected in error

(always closed). The condition is self-correcting if possible. If the error persists, return the unit

for repair at an authorized service center. The scanning operation can continue with this error

active.

LASER #1 (VERTICAL) ERROR – The laser in the vertical scanning subsystem denotes a

failure. The scanner will try three times to correct the laser operation. If the laser error

persists, the vertical scanning subsystem will be shut down and this error code will remain on

the Diagnostic Indicators.

LASER #2 (RIGHT HORIZONTAL) ERROR – The right laser in the horizontal scanning

subsystem denotes a failure. The scanner will try three times to correct the laser operation. If

the laser error persists, and the left horizontal laser (#3) is also in error, the horizontal scanning

subsystem will be shut down and this error code will remain on the Diagnostic Indicators.

LASER #3 (LEFT HORIZONTAL) ERROR – The left laser in the horizontal scanning

subsystem denotes a failure. The scanner will try three times to correct the laser operation. If

the laser error persists, and the right horizontal laser (#2) is also in error, the horizontal

scanning subsystem will be shut down and this error code will remain on the Diagnostic

Indicators.

LASER #1 (VERTICAL) HIGH CURRENT WARNING – The laser in the vertical scanning

subsystem is drawing excessive current. This could be a warning for a future total failure.

Have the unit checked at an authorized service center when convenient.

LASER #2 (RIGHT HORIZONTAL) HIGH CURRENT WARNING – The laser in the vertical

scanning subsystem is drawing excessive current. This could be a warning for a future total

failure. Have the unit checked at an authorized service center when convenient.

LASER #3 (LEFT HORIZONTAL) HIGH CURRENT WARNING – The laser in the vertical

scanning subsystem is drawing excessive current. This could be a warning for a future total

failure. Have the unit checked at an authorized service center when convenient.

LASER #1 (VERTICAL) UNDERCURRENT WARNING – The laser in the vertical scanning

subsystem is drawing too little current. The laser is probably not on. This could be the result

of a loss of the required set point in memory. Have the unit checked at an authorized service

center.

Error

Description

LASER #2 (RIGHT HORIZONTAL) UNDERCURRENT WARNING – The laser in the right

horizontal scanning subsystem is drawing too little current. The laser is probably not on. This

could be the result of a loss of the required set point in memory. Have the unit checked at an

authorized service center.

LASER #3 (LEFT HORIZONTAL) UNDERCURRENT WARNING – The laser in the left vertical

scanning subsystem is drawing too little current. The laser is probably not on. This could be

the result of a loss of the required set point in memory. Have the unit checked at an

authorized service center.

MOTOR #1 (VERTICAL) ERROR – The motor in the vertical scanning subsystem denotes a

failure. The scanner will try three times to correct the motor operation. If the motor error

persists, the vertical scanning subsystem will be shut down and this error code will remain on

the Diagnostic Indicators.

MOTOR #2 (HORIZONTAL) ERROR – The motor in the horizontal scanning subsystem

denotes a failure. The scanner will try three times to correct the motor operation. If the motor

error persists, the horizontal scanning subsystem will be shut down and this error code will

remain on the Diagnostic Indicators.

34 MOTOR #1 (VERTICAL) SPEED ERROR – The motor in the vertical section cannot be speed

controlled as desired. Have the unit checked at an authorized service center.

35 MOTOR #2 (HORIZONTAL) SPEED ERROR – The motor in the horizontal section cannot be

Power Save Modes

The MS2421/MS2422/MS2431 bar code scanners have five configurable power save modes. Refer to the

MetroSelect Configuration Guide for additional information on Power Save Modes.

1. Blink Power Save Mode:

Blinks the laser OFF & ON after a configured period of non-use.

When the scanner recognizes a bar code it will exit the Blink mode.

2. Laser Off Power Save Mode:

Turns the laser OFF after a configured period of non-use. The motor continues to spin allowing for a

faster “wake” up time.

Any movement detected by the photocell will “wake” the scanner from the Laser Off power save mode

(see Figure 31 on page 33).

3. Laser & Motor Off Power Save Mode:

Turns the laser and motor OFF after a configured period of non-use.

Any movement detected by the photocell will “wake” the scanner from the power save mode (see

Figure 31 on page 33). This mode’s “wake” time is slightly longer due to the motor’s need to restart.

4. Dual Action Power Save Mode #1:

“Blinks” the laser OFF & ON after a configured period of non-use turns the laser and motor OFF at

thirty-minute intervals.

Example:

If the power save timeout is set to 15 minutes.

Any movement detected by the photocell will “wake” the scanner from the power save mode (see

Figure 31 on page 33).

5. Dual Action Power Save Mode #2 (Default):

Turns the laser OFF after a configured period of non-use then turns the motor OFF after thirty-minute

intervals.

Example:

If the power save timeout is set to 15 minutes.

Any movement detected by the photocell will “wake” the scanner from the power save mode (see

Figure 31 on page 33).

Beeper Options and Button Functions

Power-Up Test Mode

When a MS2421/MS2422/MS2431 scanner is first powered up, it cycles through a number of self-tests

before starting normal operation. If there are any initial failures during this sequence of tests the scanner

will beep or razz to indicate the error and an error code will appear in the diagnostic indicator display.

The following are examples of the types of tests performed at power-up.

1. Memory tests

2. Hardware setup tests

3. Motor tests

4. Laser tests

5. Configuration tests

6. Interface tests

These tests are also performed on a periodic basis with the operator alerted to any failures.

Configuration Mode

All MS2421/MS2422/MS2431 bar code scanners have been configured at the factory with a set of default

communication protocols. Since many host systems have unique formats and protocol requirements, a

wide range of configurable features that may be selected with the use of the MetroSelect Configuration

Guide

(PN 00-02407x), the MS2xxx Stratos Series Configuration Addendum (PN 00-02034x) and MetroSet.
