Miniscan Block Diagram Descriptions

Decoded Scan Engine - The scan engine emits a beam of laser light that reflects off the bar code to be decoded.
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). Timing
information is analyzed by the decoder micro-controller to decode an d transmit the dat a contained in the bar code.
Data transmission is carried out using Motorola’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 (Symbol MS1204FZY/2204/2204VHD/3204 models only) and red/green
LED for audio/visual feedback, and provides for an external trigger and exter nal beeper.

The MiniScan interface board converts TTL level SSI signals to pro per RS-232 levels for connection 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 LS 1220 MiniScan host cables.

Location and Positioning

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

is recommended 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

The MiniScan can be mounted to read symbols that are automatically presented, or that are presented in a
pre-determined location. In these applications, MinScan positioning with respect to the symbol is critical. Failure to
properly position the MiniScan can result in unsatisfactory scanning performance. A thermal analysis is also
recommended.

Two methods of positioning the scanner are provided:

•

Use the Calculating the Usable Scan Length Method on page 2- 8 with consistently good quality symbols (see

page 2-9 for the Symbol MS954). This provides a mathematical solution to find the usable scan length.

•

The Testing the Usable Scan Length Method on page 2-10 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 2-9 on page 2-9):

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

where:

D = Distance (in inches) from the front edge of the host housing to the bar code.
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 Usable scan length is determined by this formula, 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 (Symbol MS954 Only)

Calculate usable scan length as follows (see Figure 2-9 on page 2-9):

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

A = Scan angle in degrees.

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

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

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

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 op tim ize per fo rm a nc e, us e th e Testing The Usable Scan Length positioning method:

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

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

quality problem that can degrade the performance of the system. Motorola 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 a
preliminary spot is determined 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 th e 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 ang les listed in each MiniScan Technical Specifications table.

7. If an additional window is to be placed between the scanner and the symbol, determine the optimum symbol

location using a representative window in the desired window po sitio n .

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 pe rforman ce . Enable the MiniScan before the symbol is presented,
if possible.

Installation 2 - 11

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 2-10 on page 2-11 illustrates
the relationship of the conveyor velocity with respect to a symbol positioned perpendicular to the conveyor direction
and Figure 2-11 on page 2-12 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)

F=Field Width

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 Motorola 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, only optical glass or cell-cast acrylic with an anti-reflection coating is highly
recommended. Following is a description of acrylic, and CR-39, another popular window material. T able 2-3 on

page 2-13 outlines the suggested window properties.

Installation 2 - 13

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 susce pt ible 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.
Typica lly 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.

2 - 14 Symbol MiniScan MSXX04 Series Integration Guide

Window Coatings

Table 2-4 on page 2-14 lists some exit window manufacturers and anti-reflection coaters.

Anti-Reflection Coatings

Apply an anti-reflection coating to the inside and/or out side 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 accept able window
positions and minimize performance degradation due to signal loss as the light pa sses through the window. Using
anti-reflection coatings on both the inside and outside of the window is high ly recommended.

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.

Embedded Window Angle and Position

If a window is placed between the MiniScan and the item to be scanned, 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 that assembly.

•

Window Angle - Angle the window at least 2o more than the tilt of the window on the scanner (see Table

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

window degrading the scanner's performan ce.

•

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 2-14. To understand the difference, test the scanner in the desired

orientation and see if the difference affects scanner performance.

Scan Angle Selection

The Symbol 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 can be set to the alternate angle (181). Se e the Simple
Serial Interface (SSI) Programmer’s Guide (p/n 72-40451-xx) for more information.

Selecting Scan Angle via Parameter Bar Code

.

The scan angle can also be set by scanning a parameter bar code (see Scan Angle on page 10-12). Once the
parameter bar code is scanned, that scan angle setting is retained.

Operation in Blink Mode

The scan angle during Blink Mode is determined by the scan angle system parameter.

Scanning Tips

When scanning, make sure the symbol to be scanned is within the scanning range. See Calculating the Usable

Scan Length Method on page 2-8. Align the bar code with the scan beam. The gr een decode LED light s to indicate

a successful decode.

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. The scanner can be configured to
scan and transmit a bar code, and then not decode the same bar code or any bar code for a set pe riod of time. See

Timeout Between Decodes on page 10-18 to customize the application to the rate at which bar codes are

presented.

Level Trigger

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

Blink

NOTE This option is supported by the Symbol MS1204FZY and MS954 only.

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 the bar code is decoded, the scanner will not decode it again until the bar code is removed.

Blink

Host Trigger

The laser is enabled and decode processing begins in response to an SSI Start Decode message from th e host.
Decode processing continues until a good decode occurs, an SSI Stop Decode message is received, or the Laser

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

3. Working range specifications: Photographic quality symbols, pitch = 10°, skew = 0°, roll = 0°,
ambient light < 150 ft. candles, and temperature = 23 °C.

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 Methodon page 2-8 describes how to calculate the usable scan length. The

scan angle is provided in Table 4-2 on page 4-5.

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 width of decode zone at any given distance when designing a system.

Calculating the Usable Scan Length Methodon page 2-8 describes how to calculate the usable scan length. The

scan angle is provided in Table 7-2 on page 7-5.
