Miniscan Block Diagram Descriptions

Decoded Scan Engine - The scan engine emits a beam of laser light that reflects off the bar code to decode.
Black bars absorb light, white spaces reflect light. The scan engine collects the reflected light and processes the
signal through several analog filters. The filtered signal is digitized into a Digitized Barcode Pattern (DBP). The
decoder micro-controller analyzes timing information to decode and transmit the bar code data. Data transmission
occurs using Zebra’s proprietary SSI Interface.

Interface Board - The interface board adapts the scan engine's interface into usable signals and data for the
intended host. It also contains a beeper (MS1204FZY/2204/2204VHD/3204 models only) and red/green LED for
audio/visual feedback, and provides for an external trigger and external beeper.

The MiniScan interface board converts TTL level SSI signals to proper RS-232 levels for connecting to any RS-232
compliant host.

DB9 - The DB9 connector provides an outlet for the various interface signals used between a MiniScan scanner
and the host. It also maintains pin compatibility with the previous generation LS1220 MiniScan host cables.

Connecting the MSXX04 via RS-232

Because Zebra scan engines use SSI communication protocol that requires hardware handshaking, you cannot
use HyperTerminal in Microsoft Windows with the MSXX04. As an alternative, Zebra offers the SSI Demo program

as a part of the SSISDK, available at no charge from the Zebra website. See Simple Serial Interface Software

Developer's Kit (SSISDK) on page 2-18. Use the SSI Demo program to quickly and easily trigger the MSXX04,

scan a bar code, and view the data on the host screen.

After connecting the MSXX04 to the host, set up the SSI Demo:

1. Insert the SSI Demo CD into the host’s CD drive and double-click on setup.exe to install the program.

Location and Positioning

CAUTION The following location and positioning guidelines do not consider unique application characteristics.

Zebra recommends that an opto-mechanical engineer perform an opto-mechanical analysis prior to
integration.

NOTE Integrate the scanner in an environment no more extreme than the product’s specification, where the

scanner will not exceed its temperature range. For instance, do not mount the scanner onto or next to a
large heat source. When placing the scanner with another device, ensure there is proper convection or
venting for heat. Follow these suggestions to ensure product longevity, warranty, and overall satisfaction
with the scanner.

Using the MiniScan as an Embedded Scanner

You can mount the MiniScan to read symbols automatically presented, or presented in a pre-determined location.
In these applications, MiniScan positioning with respect to the symbol is critical. Failure to properly position the
MiniScan can result in unsatisfactory scanning performance. Zebra also recommends a thermal analysis.

Installation 2 - 9

There are two methods of positioning the scanner:

•

Use the Calculating the Usable Scan Length Method on page 2-9 with consistently good quality symbols (see

page 2-10 for the MS954). This provides a mathematical solution to find the usable scan length.

•

The Testing the Usable Scan Length Method on page 2-11 uses real situation testing to adjust the usable

scan length to fit the application conditions.

Calculating the Usable Scan Length Method

Calculate usable scan length as follows (see Figure 2-11 on page 2-10):

L = 1.8 x (D+d+B) x Tan (A/2)

A = Scan angle in degrees.

NOTE This formula determines usable scan length, or 90% of scan line at any working distance. This formula is

based on good quality symbols in the center of the working range and length of bar code.

Calculating the Usable Scan Length Method (MS954 Only)

Calculate the usable scan length as follows (see Figure 2-11):

L = 2.0 x (D+d+B) x Tan (A/2)

d = The host housing’s internal optical path from the edge of the housing to the front of the MiniScan scanner.

B = Internal optical path from the scan mirror to the front edge of the MiniScan scanner.

A = Scan angle in degrees.

NOTE The MS954 does not require a margin on either side of the bar code to decode. The 47° scan line

provides identical scanning performance to older MiniScan devices (e.g., MS923) with a scan line of 53°.

Consider the width of the scan line at any given distance when designing a system.

Figure 2-11

Usable Scan Length Diagram

Installation 2 - 11

Testing the Usable Scan Length Method

Due to the variety of symbol sizes, densities, print quality, etc., there is no simple way to calculate the ideal symbol

distance. To optimize performance, use the Testing The Usable Scan Length positioning method:

1. Measure the maximum and minimum distances at which the MiniScan can read the symbols.

2. Check the near and far range on several symbols. If they are not reasonably consistent there may be a printing

quality problem that can degrade the performance of the system. Zebra can provide advice on how to improve
the installation.

NOTE Poor quality symbols (from bad printing, wear, or damage) may not decode well when placed in the center

of the depth of field (especially higher density codes). The scan beam has a minimum width in the central
area, and when the scanner tries to read all symbol imperfections in this area it may not decode. After
determining a preliminary spot using good quality symbols, test several reduced quality symbols and
adjust the spot for the best overall symbol position.

3. Locate the scanner so the symbol is near the middle of the near/far range.

4. Center the symbol (left to right) in the scan line whenever possible.

5. Position the symbol so that the scan line is as near as possible to perpendicular to the bars and spaces in the

symbol.

6. Avoid specular reflection (glare) off the symbol by tilting the top or bottom of the symbol away from the scanner.

The exact angle is not critical, but it must be large enough so that if a mirror were inserted in the symbol
location, the reflected scan line would miss the front surface of the scanner. For the maximum allowable angles

refer to the Skew, Pitch and Roll angles listed in each MiniScan Technical Specifications table.

7. If placing an additional window between the scanner and the symbol, determine the optimum symbol location

using a representative window in the desired window position.

8. Give the scanner time to dwell on the symbol for several scans. When first enabled, the MiniScan may take two

or three scans before it reaches maximum performance. Enable the MiniScan before presenting the symbol, if
possible.

Scan Beam

Direction of Conveyor Perpendicular to Symbol

W=Symbol Width

F=Field Width

Conveyor Applications

Conveyor applications require setting the conveyor velocity to optimize the scanner’s ability to read symbols. Also

consider the orientation of the symbol with respect to the conveyor direction. Figure 2-12 on page 2-12 illustrates

the relationship of the conveyor velocity with respect to a symbol positioned perpendicular to the conveyor direction

and Figure 2-13 on page 2-13 illustrates the relationship of the conveyor velocity with respect to a symbol

positioned parallel to the conveyor direction.

Symbol is Perpendicular to Conveyor Movement

With the symbol bars perpendicular to the conveyor belt direction (Picket Fence presentation) the relationship is:

V = (R x (F-W)) / N

where: V = Velocity of the conveyor (inches/second)

R = Scan Rate (see technical specifications)

F = 80% of width of scan beam

W = Symbol Width (inches)

N = Number of scans over symbol (minimum of 10 scans)

Figure 2-12

R = 640 scans per second

F = 80% of 6 in.

W = 4 in.

N = 10

R = Scan Rate of scanner (see technical specifications)

H = Symbol height

N = Number of scans over symbol (minimum of 10 scans)

Figure 2-13

Symbol Parallel To Conveyor Movement

Example

Use the previous formula to calculate the number of scans for a specific bar code, scanner, and conveyor speed; a
minimum of 10 scans per symbol is recommended.

R = 640 scans/sec

H = 60 mil

N = 10 scans

V = (640 x .060) / 10 = 3.84 in./sec

Embedded Applications Requiring a Window

Use the following guidelines for applications that require a window in front of the MiniScan.

NOTE Zebra does not recommend placing an exit window in front of the MiniScan; however, the following

information is provided for applications that require such a window.

Window Material

Many window materials that look perfectly clear can contain stresses and distortions that can reduce scanner
performance. For this reason, Zebra highly recommends using only optical glass or cell-cast acrylic with an
anti-reflection coating. Following is a description of acrylic, and CR-39, another popular window material.

Table 2-3 on page 2-14 outlines the suggested window properties.

2 - 14 MiniScan MSXX04 Series Integration Guide

CAUTION Consult an opto-mechanical engineer to recommend an appropriate window material and to

determine if coatings are appropriate for the specific application.

NOTE Do not use polycarbonate material.

Acrylic

When fabricated by cell-casting, acrylic has very good optical quality and low initial cost. However, protect the
surface from the environment as acrylic is susceptible to attack by chemicals, mechanical stresses, and UV light.
Acrylic has reasonably good impact resistance and can be ultrasonically welded.

CR-39

CR-39 is a thermal-setting plastic produced by the cell-casting process, and is commonly used in plastic eye
glasses lenses. CR-39 has excellent chemical and environmental resistance, including good surface hardness.
Typically it does not require hard-coating, but can be hard coated for severe environments. CR-39 has reasonably
good impact resistance and cannot be ultrasonically welded.

Chemically Tempered Float Glass

Glass is a hard material which provides excellent scratch and abrasion resistance. However, unannealed glass is
brittle. Increasing flexibility strength with minimal optical distortion requires chemical tempering. Glass cannot be
ultrasonically welded and is difficult to cut into odd shapes.

Installation 2 - 15

Window Coatings

Table 2-4 lists some exit window manufacturers and anti-reflection coaters.

Anti-Reflection Coatings

Apply an anti-reflection coating to the inside and/or outside of the window to significantly reduce the amount of light
reflected off the window, back into the scan engine. The coating can also improve the range of acceptable window
positions and minimize performance degradation due to signal loss as the light passes through the window. Zebra
highly recommends using anti-reflection coatings on both the inside and outside of the window.

Polysiloxane Coating

Polysiloxane type coatings are applied to plastic surfaces to improve the surface resistance to both scratch and
abrasion. They are usually applied by dipping, then air-drying in an oven with filtered hot air.

2 - 16 MiniScan MSXX04 Series Integration Guide

Embedded Window Angle and Position

If placing a window between the MiniScan and the item to scan, observe the following guidelines:

•

Window Clear Opening - Make the clear opening of the window large enough so that the entire scan beam

passes through the window. Cutting off any part of the beam can result in internal reflections and degrade
decode range performance. Ensure that window placement relative to the MiniScan accounts for tolerances
on all parts involved in the assembly.

•

Window Angle - Angle the window at least 2

2-5). Further tilting the window is acceptable and decreases the possibility of a secondary reflection from that

window degrading the scanner's performance.

•

Optical Working Range - Adding a window can reduce the working range of the scanner since there is a

signal loss when passing through window material. To minimize this reduction, use a special coating

described in Window Coatings on page 2-15. To understand the difference, test the scanner in the desired

orientation and see if the difference affects scanner performance.

MiniScan Scan Patterns

MS1204FZY / MS954 Scan Pattern

MS1204FZY and MS954 scanners emit a single scan line to quickly decode 1D bar codes.

Figure 3-1

Single Scan Line Scan Pattern

3 - 2 MiniScan MSXX04 Series Integration Guide

Stage 1: “Slab” Raster Pattern

Stage 2: Open Raster Pattern

MS2204 and MS2204VHD Scan Patterns

The MS2204 and MS2204VHD generate different scan patterns (Smart Raster and High Density Single Scan Line)
based on the software command received at the interface. You can use the raster pattern to read 1D bar codes and
PDF417 symbols.

NOTE The MS2204 and MS2204VHD also support omnidirectional and semi-omnidirectional scan patterns, but

are not optimized for these patterns.

Smart Raster Scan Pattern

The MS2204 and MS2204VHD can create a single line which opens vertically to read PDF417 symbols using the
Smart Raster feature. This feature autodetects the type of bar code being scanned and adjusts its pattern
accordingly, providing optimal performance on 1D, PDF417, GS1 DataBar, and Composite codes.

Figure 3-2

Raster Scan Pattern

High Density Single Scan Line Scan Pattern

The High Density single scan line appears as a "mini" raster and scans multiple areas of 1D codes to swiftly and
accurately capture data on poorly printed and damaged bar codes.

The MS3204 generates four scan patterns based on the software command received at the interface. These
patterns are Smart Raster, Semi-omnidirectional, Omnidirectional, and High Density Single Scan Line. You can use
the raster pattern to read 1D bar codes and PDF417 symbols. The omnidirectional pattern reads 1D bar codes in
an omnidirectional manner.

Smart Raster Scan Pattern

The MS3204 can create a single line which opens vertically to read PDF417 symbols using the Smart Raster
feature. This feature autodetects the type of bar code being scanned and adjusts its pattern accordingly, providing
optimal performance on 1D, PDF417, GS1 DataBar, and Composite codes.

Figure 3-4

Raster Scan Pattern

Semi-omnidirectional Scan Pattern

The semi-omnidirectional pattern is an alternative to the full omnidirectional pattern that scans highly truncated 1D
and GS1 DataBar bar codes. Present bar codes horizontally with no more than a 20

tilt.

3 - 4 MiniScan MSXX04 Series Integration Guide

Omnidirectional Scan Pattern

The high-speed rotating omnidirectional scan pattern provides aggressive performance on 1D bar codes because
there are no “holes” in the pattern. This ensures fast throughput at the point of activity and the ability to read 1D
symbols in 360

o

of rotation, eliminating the need to orient the bar code in the field of view.

Figure 3-6

Omnidirectional Scan Pattern

High Density Single Scan Line Scan Pattern

The high density single scan line appears as a "mini" raster and scans multiple areas of 1D codes to swiftly and
accurately capture data on poorly printed and damaged bar codes.

High Density Single Scan Line Scan Pattern

Scan Angle Selection

The MS1204FZY and MS954 scanners support two pre-set scan angles (see each scanner’s technical
specifications)

Selecting Scan Angle via SSI

To use SSI to select the scan angle, issue the SSI PARAM_SEND command with the NUM_SCAN_ANGLE (191)
parameter number. This is set to the default angle (182), or you can select the alternate angle (181). See the

Simple Serial Interface (SSI) Programmer’s Guide (p/n 72-40451-xx) for more information.

Selecting Scan Angle via Parameter Bar Code

.

You can also set the scan angle by scanning a parameter bar code (see Scan Angle on pa ge 10-18 ). Scanning the

parameter bar code retains that scan angle setting.

Operation in Blink Mode

The scan angle system parameter determines the scan angle during Blink Mode.

Scanning Tips

RIGHT

WRONG

012345

012345

When scanning, make sure the symbol to scan is within the scanning range. See Calculating the Usable Scan

Length Method on page 2-9. Align the bar code with the scan beam. The green decode LED lights to indicate a

successful decode.

Scan the Entire Symbol

•

The scan beam must cross every bar and space on the symbol.

•

The larger the symbol, the farther away the scanner should be positioned.

•

Position the scanner closer for symbols with bars that are close together.

Scanning 3 - 5

Position at an Angle

Do not position the scanner exactly perpendicular to the bar code. In this position, light can bounce back into the
scanner's exit window and prevent a successful decode.

Trigger Options

Continuous

The laser is enabled continuously and decode processing is continuously active. You can configure the scanner to
scan and transmit a bar code, and then not decode the same bar code or any bar code for a set period of time. See

Timeout Between Decodes on page 10-25 to customize the application to the rate at which bar codes are

presented.

NOTE This option is not recommended during scanner programming via bar code menus.

Continuous

3 - 6 MiniScan MSXX04 Series Integration Guide

Level Trigger

The laser is enabled and decode processing begins when the trigger line activates. Decode processing continues
until a good decode occurs, the trigger is released, or the Laser On Time expires. The laser is disabled once
decode processing completes. The next decode attempt does not occur until the trigger line is released and then
reactivated.

Pulse Trigger

The laser is enabled and decode processing begins when the trigger line activates. Decode processing continues
regardless of the trigger line until a good decode occurs, or until the Laser On Time expires. The laser is disabled
once decode processing completes. The next decode attempt does not occur until the trigger line is released and
then reactivated.

Level

Pulse

Blink

NOTE Only the MS1204FZY and MS954 support this option.

The laser blinks at a 25% duty cycle (reduced to 10% after 30 seconds of inactivity), until a bar code is presented.
When a bar code is presented, the laser remains on until either the bar code is decoded or removed, or the session
timeout expires. Once it decodes the bar code, the scanner does not decode it again until the bar code is removed.

Blink

Host Trigger

An SSI Start Decode message from the host enables the laser and begins decode processing. Decode processing
continues until a good decode occurs, an SSI Stop Decode message is received, or the Laser On Time expires.
The laser is disabled once decode processing completes. The next decode attempt does not occur until the host
sends the next Start Decode message.

Usable Scan Length

The decode zone is a function of various symbol characteristics including density, print contrast, wide-to-narrow
ratio, and edge accuracy. Consider the width of the scan line at any given distance when designing a system.

Calculating the Usable Scan Length Method on page 2-9 describes how to calculate the usable scan length. Table

Notes:

1. Contrast measured as Mean Reflective Difference (MRD) at 650 nm.

2. Near ranges on largely depend on the width of the bar code and the scan angle.

3. Working range specifications: Photographic quality symbols, pitch = 15°, skew = 0°, roll = 0°,
ambient light < 150 ft. candles, and temperature = 23 °C, Vcc = 5V.

4. Measured from the front of the scanner.

Usable Scan Length

The decode zone is a function of various symbol characteristics including density, print contrast, wide-to-narrow
ratio, and edge acuity. Consider the width of the decode zone at any given distance when designing a system.

Calculating the Usable Scan Length Method on page 2-9 describes how to calculate the usable scan length. Table
7-2 on page 7-5 provides the scan angle.
