INSTALLATION
QUICK INSTALLATION OUTLINE
The following is a quick preview of the steps required for 1st 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 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/MS242 models have a die-cast housing to dissipate heat allowing the unit to operate without a ventilation fan.
Metrologic recommends that the temperature surrounding the unit does not 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, Metrologic recommends removing the unit completely from the
checkout counter.
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.
Metrologic recommends using a switched AC outlet. 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 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.

13
INSTALLATION
UNPACKING THE UNIT
1. Make sure the shipping box is top-side up before opening.
2. Remove the accessories box and check the box’s content for the following
items.
•Product Manuals
•Power Supply
•Communication Cables
3. Lift the scanner out of the shipping box by gripping the bottom of the
unit on both sides.
Important! Do not lift the unit out of the box by gripping the sides of the
platter.
4. Carefully remove the shipping foam around the unit.
Important! Do not turn the unit upside down or tilt the unit onto its side
while removing the shipping foam. The platter is not attached
to the unit and can fall off!
5. Lift the platter off the unit and store it in a safe location until the unit is
installed in the checkout counter.
Once the unit has been properly installed in the checkout counter,
remove all protective film covering the platter’s horizontal window,
the horizontal window under the platter on the unit base, and the
vertical window. The unit will not function properly if the
protective films are not removed.

INSTALLATION
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.
Configuration bar codes are located in the MetroSelect Configuration Guide (MLPN 00-02407x) and the
MS2xxx Stratos Series Configuration Addendum (MLPN 00-02034x).
1. Turn off the host system.
2. Plug the 10-pin RJ45 end of the RS232 interface cable (MLPN 57-57210x-N-3)
into the 10-pin socket labeled Scanner Host RS232, on the bottom of the scanner. Refer to figure on page 17.
3. Connect the other end of the RS232 cable to the proper communication port on the host device.
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 (MLPN 46-002xx) into the 3-pin Molex socket labeled, DC Power In, on the bottom of the
scanner.
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.
Metrologic recommends using a switched AC outlet. 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. Scan the Recall Defaults bar code.
The Recall Defaults bar code is located in the MetroSelect Configuration Guide (MLPN 00-02407x), under Need to
Start Over.
8. Configure the scanner to match the host system’s RS232 parameters.
Refer to the MetroSelect Configuration Guide (MLPN 00-02407x) under Section G: RS232 for enabling RS232
Mode (scan the recall defaults bar code first).
