View indicates the current view (with a dot before the item) and allows you to quickly move to other views which are also accessed by clicking the icons on the toolbars.

It also allows you to access the Barcode Dialog.

Barcode Dialog

In the Barcode Dialog you can create bar code symbols by directly typing in the text bar code text you want to appear in

Code 128 bar code symbols. This is a very useful tool for creating configuration symbols which allows you to configure your reader by reading the bar code symbols you print out. To configure the size, text and caption parameters, see

"Bar Code Options tab"

on page 2-8.

EZ Button Operation

The MS-860 EZ Button provides a quick and easy way to perform routine tasks such as Read Rate test and

Calibration.

Defaults

In the default positions the following operations occur:

• Single Beep and green flash:

Starts a

Read Rate

test

• Two Beeps and green flashes:

Starts a

Calibration

• Three Beeps and green flashes:

Save for Power-on

Using the EZ Button

EZ

The EZ Button has three positions, selectable by the length of time that the button is held down as indicated by one, two, and three beeps and percentage

LEDs in succession.

For example, for three beeps, press and hold the EZ

Button. You will first hear a single beep and see the

20% LED turn ON. Continue to hold and you will hear two quick beeps and see the 40%

LED turn ON. Do not release until you hear three quick beeps or see the 60% LED turn

ON.

Programmable Beeps

Each beep condition (1, 2 or 3) can be programmed for any of 8 options as presented in

"EZ Button Modes"

on page 3-4.

Programmable Options

The EZ Button can also be programmed for alternative operations including restore factory defaults as well as a quick save feature for calibration results. (See

"EZ Button

Options"

on page 3-6.)

The positions are selected by the length of time the button is held. When you want to select position one, you press and hold the button until one beep along with a single green flash is emitted from the reader and the 20% LED turns ON.

To select position two, you continue to hold until you hear two short beeps and see two green flashes and the 40% LED turn ON.

Finally, to select position three, you continue to hold the button until you hear three short beeps and see three green flashes and the 60% LED turn ON.

For example, if you want to select the function for position three, you will hear one short beep, then two short beeps, and finally three short beeps and the 20%, 40%, and

60% LEDs turn ON in progression.

The following table lists the options for the three positions with the default positions highlighted:

Calibration

Calibration Overview

When a

Calibrate

command is sent, all symbologies are enabled except PDF417

1

and

Pharmacode.

2

The reader looks for readable bar code symbols, and records the highest read rates it encounters while stepping through various settings. Any new symbologies decoded during calibration are enabled at the end of calibration. However, no previously enabled symbologies are disabled.

The settings that the calibration routine uses can be pre-set by the user and include the following:

Calibrates for:

Symbol position in the raster pattern

Video (gain and tracking)

Scan speed (scans per second)

Laser power (attempt minimum power)

Laser framing (shortens scan line to fit symbol)

Default Status

Searches for symbol but does NOT save to NOVRAM

Enabled

Enabled

Enabled

Disabled

The calibration settings can be changed by application requirements. See

"Calibration

Options"

on page 4-6 for details.

Calibration Methods

There are four ways to start calibration:

• The EZ Button.

• ESP

Calibration

menu.

• Serial command

<@CAL>

.

• From embedded calibration menu

<@>

(see


on page A-24).

Configuration Database

When a symbol is calibrated, the resulting settings are automatically loaded into the

Current

index of the configuration database. From here it can be copied into any of the active database indexes and the indexes are compiled in the configuration database are applied in real time operations. See Chapter 5,

"Configuration Database"

.

1. Calibration does not function with PDF417 symbols. However, you can substitute a Code 128 symbol with the same mil size as your PDF417. When you do this, enable Code 128 and after calibration, switch back to PDF417.

2. Note: If using an I 2 of 5 symbol, verify that the number of characters in the symbol being scanned matches the code length enabled for the I 2 of 5 code type (default is 10 and 6). See

"Interleaved 2 of 5"

on page 9-11.


4-3

Calibrating a Symbol

Calibrating a Symbol

1. Position symbol so that the raster scan lines are evenly spread above and below the symbol and will be parallel with the symbol length as shown in the illustration.

2. Enable those settings required for your specific application.

3. Start the calibration procedure.

(See

"Calibration Methods"

on page 4-3.)

If in the default Search mode (

"Raster

Options"

on page 4-6), the raster pattern will change to a single line, move to its topmost position, and sweep slowly down until it

Calibration Options


Before starting the calibration routine, you can make changes to the parameters that will be included in the process. If you make no changes, calibration will use the default parameters as described in this section.

Note: The changes made in this section will only apply to EZ Button,

<@>

, and

<@CAL>

defaults.

Raster Options

As Is

Usage:

Definition:

Useful when the raster pattern has already been aligned to the symbol.

Raster position does not change during calibration. Raster will continue to operate as per the raster command

<K506>

.

Frame

Definition:

Similar to “Search” setting, except at the end of calibration, the raster is swept through its full range of motion again, and the top and bottom location of the first symbol found are used to update the raster's top and bottom offset novram configuration. Also, the resulting configuration parameters are saved to the raster novram.

Search

Definition:

At the beginning of calibration, the raster sweeps through its entire range of motion in an attempt to find a symbol. When found, the scan line is placed in the middle of the symbol and held as a straight line for the remainder of the calibration process. If no symbol is found, the scan line will be placed straight line and centered straight out of the window for the remainder of the calibration process.

Calibration

Straight

Definition:

The scan line is set as a centered straight line during calibration. This is equivalent to Top Position = Bottom Position = 127 in the raster command

<K506,,127,127>

Overview of Configuration Database

Definition:

Usage:

Up to 10 configuration database indexes can be set up either manually or derived in part from calibration results as explained in Chapter 4,

"Calibration".

When enabled, these settings will be applied sequentially and repeatedly during the read cycle.

Useful in applications in which a variety of symbol conditions require different settings that can be applied in real time. For example, a package with a Code 39 and Code 128 symbol appearing consistently in different locations as they move through the scan range during a read cycle can be read by the reader if the proper settings are in the active configuration database.

Operation of Database

Operation of Database

Once Configuration Database is enabled (by setting the Number of Active Indexes to any number other than 0) the reader’s current settings for Gain, AGC Mode, Track-

ing, Raster Top, Raster Bottom, Raster Speed, Laser Framing Status, Laser On

Position, Laser Off Position, Laser Power and Background Color will no longer impact reader operation. For those parameters, only settings that are in the database and enabled will be used during the normal read cycle.

Number of Active Indexes

Definition:

Number of data base records (groups of settings) that will be used automatically during the read cycle. If set to 0, the reader only uses the current settings, not database entry settings.

Serial Cmd:

When set to 0, the reader will repeatedly cycle through all active database indexes until the read cycle ends. When set to any number greater than 0, the reader will only cycle the active database entries the defined number of times before adopting the settings from the last active index for the remainder of the read cycle.

Note: It is possible for the read cycle to end before the reader is able to cycle trough all data base entries.

Note: When the reader is in Continuous Read and Continuous Read 1 and not in

Read Rate, it will only use current settings, not database entry settings. However, the user may still send the

Host Protocol

Usage:

Definition:

In general, the point-to-point protocols will work well in most applications. They require no address and must use RS-232 or RS-422 communications standards.

Protocols define the sequence and format in which information is transferred between the reader and the host, or in the case of Multidrop, between readers and a concentrator.

Serial Cmd:

<

K140,

protocol>

Default:

Point-to-Point

Options:

0 = Point-to-Point

1 = Point-to-Point with RTS/CTS

2 = Point-to-Point with XON/XOFF

3 = Point-to-Point with RTS/CTS &

XON/XOFF

4 = Polling Mode D

5 = Multidrop

6 = User Defined

7 = User Defined Multidrop

If selecting one of the options from 0 to 4 (Point-to-Point, Point-to-

Point with RTS/CTS, Point-to-Point with XON/XOFF, Point-to-

Point with RTS/CTS and XON/XOFF, or Polling Mode D), use the

<

K140,

protocol> format.

Options 5 through 7 are special cases and are discussed later in this section.

Point-to-Point (standard)

Usage:

Used only with RS-232 or RS-422.

Definition:

Standard Point-to-Point requires no address and sends data to the host whenever it is available, without any request or handshake from the host.

Serial Cmd:

<

K140,0

>

6-4


Communications

Point-to-Point with RTS/CTS

Usage:

A reader initiates a data transfer with an RTS (request-to-send) transmission. The host, when ready, responds with a CTS (clear-to-send) and the data is transmitted. CTS and RTS signals are transmitted over two dedicated wires as defined in the RS-232 standard.

Used only with RS-232.

Definition:

Point-to-Point with RTS/CTS (request-to-send/clear-to-send) is a simple hardware handshaking protocol that allows a reader to initiate data transfers to the host.

Serial Cmd:

<

K140,1

>

Point-to-Point with XON/XOFF

Usage:

If an XOFF has been received from the host, data will not be sent to the host until the host sends an XON. During the XOFF phase, the host is free to carry on other chores and accept data from other devices.

Definition:


This option enables the host to send the XON and XOFF command as a single byte transmission command of start (^Q) or stop (^S).

Serial Cmd:

<

K140,2

>

Point-to-Point with RTS/CTS & XON/XOFF

Usage:

Definition:


This option is a combination of Point-to-Point with RTS/CTS and

Point-to-Point with XON/XOFF.

Serial Cmd:

<

K140,3

>

Polling Mode D

Usage:

Definition:

When in Polling Mode D, an address of 1 is automatically displayed on the configuration screen. However, during transmission, a 1C hex poll address (FS) and a 1D hex select address (GS) are substituted for the 1.

Like Point-to-Point, Polling Mode D requires a dedicated connection to the host; but unlike Point-to-Point, it requires an address and must wait for a poll from the host before sending data.

Serial Cmd:

<

K140,4

RS-232/422 Host Port

Multidrop

See also MS-860 Quick Start Help for Multidrop setup.

See also

"Multidrop Communications"

on page A-26.

Usage:

Definition:

The MS-5000 can be used as a concentrator to a single host port connection.

Multidrop allows up to 50 devices to be connected to a single RS-485 host, with the reader assigned an unique address (from 01 to 50). When

Multidrop is selected, the protocol characters for RES, REQ, etc. are assigned automatically.

Multidrop

Addresses:

Each address has its own separate poll and select address (from 1C to 7F hex).

Serial Cmd:

If selecting Multidrop

<K140,5>

an address must be defined and appended to the command string.

Options:

Format: <

K140,5

,address[01 to 50]>

01 through 50

Note: Readers linking up to a Microscan MS-5000 multidrop concentrator must be configured in standard multidrop protocol.

User Defined Point-to-Point

Usage:

Definition:

Used for developing custom protocols in polled or unpolled mode.

User Defined Point-to-Point allows the user to customize the point-topoint protocol.

Serial Cmd:

<

K140,6

,RES,address,REQ,EOT,STX,ETX,ACK,NAK>

User Defined Address

Definition:

User Defined is considered to be in a polled mode only if an address has been assigned.

Serial Cmd:

,REQ,EOT,STX,ETX,ACK,NAK>

Default:

No address

Options:

Any ASCII character except a null.

6-6


Communications

User Defined Example

Example:

An ACK/NAK protocol can be configured using User Defined. The reader will transmit data to the host when an ACK is received. If a NAK or response timeout occurs, the reader will re-send the data to the host up to 3 more times before aborting.

Tip: To use User Defined Point-to-Point, first select Point-to-Point

<K140,0>

and then User Defined

<K140,6>

.

Example: To select an unpolled ACK/NAK User Defined protocol with

LRC disabled, send

<K140,0><K140,6,,,,,,,^F,Û><K145,0>

. ACK and NAK will be displayed in the menu.

Tip: To use User Defined Point-to-Point, first select Point-to-Point

<K140,0>

and then User Defined

<K140,6>

.

Serial Cmd:

<

K140,6

,RES,address,

REQ,EOT,STX,ETX,ACK,NAK

>

Default:

No assignment

Options:

Any ASCII character except a null. Control characters can be used to define RES through NAK in serial commands.

User Defined Multidrop

Note: Any ASCII character except a null (00) and a Â (01) can be assigned as an address. Control characters can be used to define RES through NAK in serial com-

mands. (See

"Communication Protocol Commands"

on page A-15.)

Usage:

Definition:

Used when connecting to a concentrator or other device that does not match standard multidrop protocol.

User Defined Multidrop allows the user to customize the polling protocol.

If selecting User Defined Multidrop (7), complete the format by either choosing new parameters or place commas where unchanged data fields occur.

Serial Cmd:

<

K140,7

,RES,address,REQ,EOT,STX,ETX,ACK,NAK>

For User Defined Multidrop, first select Multidrop

<K140,F140,5>

, then User Defined Multidrop

<K140,140,F7...>

.

Address:

Any single character (02 hex to 7E hex) in the ASCII table can be assigned as the address character. The character chosen is used as the poll character and the subsequent ASCII character becomes the select character. For example, if a ^B (02 hex) is selected as the address, ^C

(03 hex) becomes the select address that the host will use in sending host select commands.

Note: Definitions of commands in User Defined and User Defined Multidrop must be duplicated in host applications to enable poll and select sequences to execute correctly during transmission.

Note: Typically, parameters in User Defined Multidrop are defined by first enabling

Multidrop, then enabling User Defined Multidrop. This pre-loads multidrop characters into the parameters. Then changes are made to individual characters to match the host or other requirements.

RS-232 Auxiliary Port

RS-232 Auxiliary Port

Note: The aux port cannot be used with RTS/CTS.

As with the host port parameters, the auxiliary terminal’s settings (baud rate, parity, stop bits, and data bits) must be identical with those of the auxiliary device.

Usage:

Definition:

These commands set the communication parameters with the auxiliary port which can be used to configure menus, send data to the host, display data transmissions originating from the host of the reader, and relay data from other readers set in tandem (daisy chained). If the reader’s host port needs to be dedicated to the host, but configuration must be done on the fly, the auxiliary port can be set to accept configuration changes by Command Processing Mode (see

"Command Processing

Mode"

on page 6-14).

An auxiliary port connects the reader to a remote display or to other readers that can display or transfer data.

Transparent Mode

Usage:

Definition:

Often used in conjunction with handheld readers. Employs an auxiliary readout to detect mis-applied bar code symbols.

In Transparent mode data is passed between the auxiliary port and the host. The reader buffers data from the auxiliary port and echoes the keyed data on the auxiliary port. I

Data initiated from the Auxiliary Port

• Auxiliary port data is passed through to the host whenever a return key is pressed at the auxiliary port or symbol data is sent.

• Whenever aux port data is sent with symbol data, the aux port data will appear between the preamble and the symbol data.

Host

Daisy Chain Mode

Usage:

Definition:

Used in applications where:

• A symbol might be scanned in both ladder and picket fence directions.

• A bar code symbol may be present on multiple sides of a package.

• Bar code symbols are presented at different depths.

In a daisy chain application, readers are connected in tandem or “daisy chain” and decoded data is relayed from one reader to another on up to the host.

A master reader has its host port linked to the host computer and its auxiliary port linked to the host port of the first secondary reader in the chain. Thereafter, each secondary’s auxiliary port is linked to the host port of the secondary that is further from the host in the daisy chain.

Each reader in the daisy chain can be assigned an ID that accompanies any data that it sends.

Serial Cmd:

<


,baud rate,parity,stop bits,data bits,daisy chain


Options:

Function:

4 = Daisy chain

Before the master reader times out, it checks its auxiliary port for data. It should be set to wait at least

20

mS for each secondary in the daisy

chain. (See

"Read Cycle Timeout"

on page 7-15.) If no data is received within the read cycle timeout, the master sends a noread message to the host. Otherwise the complete data is sent.

If for example the master reader is set to timeout in 120mS, the first secondary reader downstream might be set to 100mS, the next to 80mS, and so forth, thus assuring that at least 20mS elapses between transmissions.

a

Daisy-chained readers can send a series of symbols by enabling Multi-

symbol and a common multisymbol separator. If the master reader does not receive the expected number of symbols, noread messages are appended to the data string to make up the difference between the number of symbols enabled in Multisymbol and the number of symbols read.

For example, a master and two secondary readers have Number of

Symbols set to 3 and Multisymbol Separator defined as %. If the master and the first secondary reader do not find symbols, but the next secondary reader registers a good read, the transmitted results would be: symbol data % noread % noread.

a. The above example is based on the best case. Other factors such as baud rate, dynamic focus timing, number of characters in a given symbol, and the number of secondaries in the daisy chain can affect timing and may need to be included in your calculations for complete accuracy.


6-13


Conditions:

The conditions for a daisy chain application are as follows:

Host Secondary

1. The master reader’s trigger must be Serial or

External; the secondary readers’ triggers are configured for Serial.

2. All readers are enabled to Daisy Chain mode.

Master

3. Each reader’s auxiliary port must be connected to the Host port of its secondary reader.

4. Each secondary reader in the daisy chain must be set to send its data no less than

20

mS before its preceding reader.

5. All but the master reader must have Postamble enabled and set to

CR (^M) only.

6. All but the master reader must have their noread messages disabled.

7. If Multisymbol is enabled, Multisymbol Separator characters must match in all readers and Number of Symbols must be set to number large enough to include all the symbols it may itself read plus the number of symbols that it will be expected to relay to the host or the next reader up the line.

8. Symbology ID enable/disable must be the same in all readers.

9. All but the master reader must have their diagnostic warning messages disabled.

10. Daisy Chain ID Status enable/disable and the number of characters in Daisy Chain ID must be the same in all readers.

Daisy Chain Autoconfigure

Note: Not in ESP.

Usage:

Definition:

For quick setup and configuration of the daisy chain network.

Daisy Chain Autoconfigure is issued to the master reader in the daisy chain and the software responds as follows:

• Counts the number of secondary readers in the daisy chain.

• Assigns an internal ID number (1...n) to each secondary reader, where the first secondary reader is number 1 (and it’s own ID being a 0).

• Propagates the communications settings and the relevant operating modes of the master reader to the host and auxiliary ports of each secondary reader.

• Resets each secondary reader.

• Verifies that each secondary reader has acquired the new settings.

Serial Cmd:

<

K150DAISY

>

Note: All secondary readers must be set to Serial for Daisy Chain to function.

See

"Trigger"

on page 7-6.

When setting up a daisy chain operation, do the following:

1. Set the master (the reader connected to the host) reader to Serial.

This sets all the readers in the daisy chain to Serial when the command is carried out.

Before Autoconfigure you must set the master reader to Serial (

S

):

Communications

LRC Status

(Longitudinal Redundancy Check)

Usage:

Definition:

Used when extra data integrity is required.

An error-checking routine that verifies the accuracy of transmissions. It is the exclusive OR of all characters following the STX (start of text) up to and including the ETX (end of text). What this means is that the binary representation of all the characters in a transmissions are cumulatively added in a column and each resulting odd integer is assigned a 1 and each even integer a 0 (two 1s = 0, two 0s = 0, a 1 and a 0 = 1). The extra LRC character is then appended to the transmission and the receiver connected to the host port performs the same addition and compares the results.

Response Timeout

Response Timeout

Usage:

Definition:

Used only when a response is required from the host. While in Multi-

drop, if the reader does not receive an ACK or NAK from the host after sending polled data, it will act on a fault. The reader can be set to wait indefinitely by setting Response Timeout to zero.

Time the reader will wait before timing out if ACK, NAK, and ETX are enabled, and a host response is expected.

Serial Cmd:

<

K143,response timeout

Default:

2

(x 10 = 20 mS)

Options:

0 to 255 in 10mS increments (0 to 2.55 seconds)

(A zero (0) setting causes an indefinite wait.)

After you’ve established communications and completed basic read rate testing, you will need to address the spatial and timing parameters associated with your application.

In a typical operation a bar coded item moves along a line past a reader. A trigger or timer activates a read cycle during which the reader actively searches for symbols. You will need to decide how to initiate the read cycle and how and when to end it.

Note: When assigning characters in user-defined fields, the characters

Multisymbol

Multisymbol

Usage:

Definition:

Conditions

Commonly used in shipping applications where a shipping symbol contains individual bar codes for part number, quantity, etc. This feature allows one trigger to pick up all the symbols. AIAG and UCC/EAN-128 are two application standards that address this need.

Allows the user to set up conditions that will allow more than one symbol to be decoded and output.

The following conditions apply:

1. All noread messages are posted at the end of the data string.

2. If more than one symbol is within the scan beam at the same time, symbol data may not be displayed in the order of appearance.

3. If Matchcode Type is set to Sequential or if Trigger is set to

Continuous Read 1 Output, Number of Symbols will default to

1 (if set to any number greater than 1).

4. The maximum number of characters in any one linear symbol is

128

.

5. The maximum number of output characters for all symbols is

3072

, including separators, and optimal formatting.

Number of Symbols

Usage:

Definition:

Commonly used where a shipping symbol contains individual symbols for part number, quantity, etc. UCC/EAN-128 is an example of a symbology that address this need.

Number of Symbols allows the user to define up to 12 bar code symbols that can be read in a single read cycle.

Conditions:

The following conditions apply:

1. When Number of Symbols is set to Single, the read cycle ends when one symbol is decoded and output.

2. When Number of Symbols is set to Multiple, all decoded symbol data (for both the same and different symbols) are output while the read cycle is active and/or no timeout has occurred.

Trigger

Trigger

Trigger Mode

Definition:

The type of trigger event that will initiate the read cycle.

Serial Cmd:

Default:

Continuous Read

Options:

0 = Continuous Read

1 = Continuous Read 1 Output

2 = External Level

3 = External Edge

4 = Serial Data

5 = Serial Data & External Edge

Continuous Read

Usage:

Definition:

Continuous Read is useful in testing symbol readability or reader functions. It is not recommended for normal operations.

In Continuous Read, trigger input options are disabled, the reader is always in the read cycle, and it will attempt to decode and output every scan crossing a symbol. When To Output and Noread options have no effect on Continuous Read.

Serial Cmd:

<

K200,0

>

7-6


Read Cycle

Continuous Read 1 Output

Usage:

Definition:

Continuous Read 1 Output can be useful in applications where it is not feasible to use a trigger and all succeeding symbols contain different information. It is also effective in applications where the objects are hand-presented.

In Continuous Read 1 Output the reader self-triggers whenever it decodes a new symbol or a timeout occurs.

If End Of Read Cycle is set to Timeout and the symbol doesn't change, the reader will repeat the output at the end of each timeout period. For example, if Timeout is set to one second, the reader sends the symbol data immediately and repeats the output at intervals of one second for as long as the symbol continues to be scanned.

If End Of Read Cycle is set to New Trigger, the reader will send the current symbol data immediately, but send it only once. A new symbol appearing in the reader’s range will be read and sent immediately provided it is not identical to the previous symbol read.

Serial Cmd:

<

K200,1

>

Caution: In automated environments, Continuous Read 1 Output is not recommended because there is no one to verify that a symbol was missed.

Note: If Trigger is set to Continuous Read 1 Output, Number of Symbols will default back to 1 (if set to any number greater than 1).


7-7

Trigger

External Level

Usage:

This mode is effective in an application where the speeds of the conveying apparatus are variable and the time the reader spends scanning each object is not predictable. It also allows the user to determine if a noread has occurred.

1

Object detector

1

Initiate Read Cycle:

Object # 1, moving in front of the detector beam, causes a change in the trigger state, initiating the read cycle.

End Read Cycle:

The same object, moving out of the detector beam, causes another change in the trigger state, ending the read cycle.

Active

External Level Trigger

Definition:

External Level allows the read cycle to begin when a trigger (change of state) from an external sensing device is received. The read cycle endures until the object moves out of the sensor range and the active trigger state changes again.

Serial Cmd:

<

K200,2

>

Important: Level and Edge apply to the active logic state (Open or Closed) that exists while the object is in a read cycle, between the rising edge and falling edge. Ris-

ing edge is the trigger signal associated with the appearance of an object. Falling edge is the trigger signal associated with the subsequent disappearance of the object.

7-8


Read Cycle

External Edge

Usage:

Definition:

This mode is highly recommended in any application where conveying speed is constant or if spacing, object size, or timeouts are consistent.

External Trigger Edge, as with Level, allows the read cycle to begin when a trigger (change of state) from an external sensing device is received. However, the passing of an object out of sensor range does not end the read cycle. The read cycle ends with a good read output or, depending on End of Read Cycle setting, a timeout or new trigger occurs.External Trigger Edge, as with Level, allows the read cycle to begin when a trigger (change of state) from an external sensing device is received. However, the passing of an object out of sensor range does not end the read cycle. The read cycle ends with a good read or with a noread when a No Decode Timeout occurs.

Serial Data

Usage:

Definition:

Highly recommended in any application where conveying speed is constant or if spacing, object size, or timeouts are consistent.

In Serial Data, the reader accepts an ASCII character from the host or controlling device as a trigger to start a read cycle. A Serial Data trigger behaves the same as an External Edge trigger.

Serial Cmd:

<

K200,4

>


7-9

Trigger

Serial Data or External Edge

Usage:

Serial Data or External Edge is seldom used but can be useful in an application that primarily uses an external sensing device but occasionally needs to be manually triggered. An auxiliary terminal can be connected to the aux port so the user can send the serial trigger character through the reader to the host.

Definition:

In this mode the reader accepts either a serial ASCII character or an external trigger pulse to start the read cycle.

Serial Cmd:

<

K200,5

>

7-10


Read Cycle

Trigger Filter Duration

Usage:

Definition:

Trigger Filter Duration is useful where trigger bounce or noise pulses could cause false triggers.

Trigger Filter Duration is the minimum time that must elapse before a trigger pulse is considered valid.

Serial Cmd:

Usage:

Definition:

Users can select the trigger state that will operate with their systems. (If using the Microscan object detector, use Active Closed.)

Determines whether a positive or negative transition will initiate the read cycle.

Serial Cmd:

<

Serial Trigger

Serial Trigger

Usage:

Definition:

Defines the trigger character that initiates the read cycle.

An on-line host command composed of a single ASCII host serial trigger character that initiates or ends the read cycle.

Trigger characters are of two types: delimited and non-delimited. A delimited character is enclosed within angle bracket delimiters

< >

.

A non-delimited trigger character is one that either starts or ends the read cycle and is NOT enclosed by delimiters such as

< >

.

Serial Trigger Character

Usage:

Definition:

Useful in applications where a single serial character enclosed in angle brackets initiates the read cycle.

A trigger character is one that starts the read cycle, is enclosed by delimiters

< >

and can only be sent when the trigger mode is set to Serial

Data or Serial Data & Edge.

Serial Cmd:

<

K201,serial trigger character

>

Default:

^]

(corresponds to

<GS>

)

Options:

Any single 7-bit ASCII character, including control characters, except NUL

(00H), an existing host command character, or an on-line protocol character.

Note: Serial Data or Serial Data & Edge triggering mode must be enabled for Serial

Trigger Character to take effect.

7-12


Read Cycle

Non-delimited Start and Stop Characters

Note: If the serial trigger character that you assign is already assigned as an operational command—for example a “Z” character that is used in the

<Z>

command—the command will no longer function as intended.

Both Start and Stop non-delimited characters can be defined and will function according to the trigger event, as follows:

When defining Start and Stop trigger characters, the following rules apply:

• In External Edge the reader looks only for the start trigger character and ignores any stop trigger character that may be defined.

• In External Level, the start trigger character begins the read cycle and stop trigger character ends it. Note that even after a symbol has been decoded and the symbol data transmitted, the reader remains in External Level trigger read cycle until a

Stop character is received.

• In Serial Data & Edge trigger mode, command, either a Start Trigger Character or a hardware trigger can start an Edge trigger read cycle.

Start Character (non-delimited)

Usage:

Definition:

Useful in applications where different characters are required to start and end a read cycle.

A single ASCII host serial trigger character that starts the read cycle and is not enclosed by delimiters such as

<

7-13

End of Read Cycle

End of Read Cycle

Note: When to Output must be set to End of Read Cycle before this command can be active.

Definition:

The read cycle is the time during which the reader will attempt to read and decode a symbol. At the end of a read cycle the reader stops reading symbols and sends the symbol data or noread message to the host.

End of Read Cycle Mode

Definition:

A read cycle can be terminated by a new trigger, a timeout, or a combination of both.

Serial Cmd:

<

K220,end of read cycle

,read cycle timeout>

Default:

Timeout

Options:

0 = Timeout 1 = New Trigger 2 = Timeout & New Trigger

Note: When operating in Continuous Read or Continuous Read 1 Output, the reader is always in the read cycle.

Timeout

Usage:

Definition:

Typically used with Serial or Edge and Continuous One.

It is effective in highly controlled applications when the maximum length of time between objects can be predicted. It assures that a read cycle ends before the next bar coded object appears, giving the system extra time to decode and transmit the data to the host.

Timeout ends the read cycle when the time set in Read Cycle Timeout elapses or “times out.”

If in Continuous Read 1 Output, a timeout initiates a new read cycle and allows the same symbol to be read again.

With either External Edge, Serial Data, or Serial Data & Edge enabled, a timeout ends the read cycle and symbol data or a noread message is sent to the host.

With External Level enabled, the read cycle does not end until the falling edge trigger or a timeout occurs. The next read cycle does not begin until the next rising edge trigger.

7-14


Read Cycle

New Trigger

Usage:

Definition:

New Trigger is an effective way to end a read cycle when objects move past the reader at irregular intervals (not timing dependent).

New Trigger ends the current read cycle and initiates a new one when a new trigger occurs. New Trigger refers only to a “rising edge” trigger.

With either External Edge, Serial, or Serial or Edge enabled, an edge or serial trigger ends a read cycle and initiates the next read cycle.

In the case of External Level, a falling edge trigger ends the read cycle but the next read cycle does not begin until the occurrence of the next rising edge trigger.

Note: When New Trigger is enabled and if not in External Level mode, Laser On/

Off will have no effect. When noreads occur, the laser will remain on.

Timeout or New Trigger

Usage:

Definition:

Useful in applications that require an alternative way to end the read cycle. For example, if an assembly line should stop completely or the intervals between objects are highly irregular.

Timeout or New Trigger

is identical to Timeout, except that a timeout

or a new trigger (whichever occurs first) ends the read cycle.

Read Cycle Timeout

Usage:

Definition:

Useful in many tightly controlled applications which require a read cycle to end before the next object appears and therefore need the flexibility of a timeout adjustment.

Read Cycle Timeout is the time span of the read cycle and is represented in 10 mS increments. It is used in conjunction with External

Edge or Serial Trigger.

Serial Cmd:

<

K220,

end of read cycle,

read cycle timeout

>

Default:

100

(Corresponds to one second or 1000 mS.)

Options:

1 to 65535. (Divide any positive number entered by 100 to determine the time in seconds.)

Timeout does not function when in Continuous or Level read cycle modes.

Continuous 1: The reader will only read a given symbol once until a timeout occurs or a different symbol is presented.

Note: A minimum setting of 2 is recommended.

Note: Timeout or Timeout or New Trigger under End of Read Cycle must be enabled for Read Cycle Timeout to take effect.


7-15

Decodes Before Output

Decodes Before Output

Note

:

When setting up, determine if the reader’s scan speed is capable of scanning your longest symbol the required number of times.

Decodes Before Output Mode

Usage:

Definition:

Useful when the highest level of reliability is required.

When consecutive is enabled, the number set in Decodes Before Out-

put must be achieved consecutively before decoded data is sent. For example, if Number Before Output is set to 5, then the data will be output whenever five decodes occur in succession.

When the default non-consecutive is set, whenever a cumulative number of decodes is achieved, decoded data is sent. For example, if non-consecutive is enabled and Decodes Before Output is set to 10, then data will be sent when the total number of decodes reaches 10 regardless of the number of bad reads between decodes.

Serial Cmd:

<

K221,

number before output,

decodes before output mode

>

Default:

Non-consecutive

Options:

0 = Non-consecutive 1 = Consecutive

Number Before Output

Usage:

Definition:

This is a very useful feature to increase reliability of reads for symbologies that do not have internal error checking such as Pharmacode.

The number of decodes required per symbol before a symbol’s decoded data is sent. It requires the reader to successfully decode a symbol a designated number of times before it is sent. If it doesn’t achieve the number of good reads during the read cycle, then a noread will be sent.

Note: Higher settings will decrease throughput speed.

Automatic Gain Control (AGC)

AGC Sampling Mode

Usage:

Definition:

AGC Sampling allows you to specify how automatic gain control sampling will be done.

AGC is the acronym for Automatic Gain Control. AGC increases the depth of field by attempting to maintain signal strength at a constant level regardless of the range of the bar code symbol.

Serial Cmd:

<

Disabled

Usage:

Definition:

Leading Edge

Disabled is not recommended, but can be useful in certain applications in which symbols do not require a large depth of field.

When AGC Sampling is set to Disabled, gain levels can only be manually controlled by the Gain command.

Usage:

Definition:

Leading Edge is rarely used, but in some cases can improve scan rates when symbols are skewed and the leading edge of a symbol is difficult to locate.

Finds the leading edge of a symbol by looking for a 40µS quiet zone followed by the number of transitions set in

"Transition Counter"

on page

7-21, stores the highest value of the samples, and adjusts the AGC accordingly at the end of the scan.

Continuous

Usage:

Definition:

Continuous is the default and the preferred mode for sampling analog signal amplitude.

Samples AGC throughout the scan at the rate set in

"Transition

Counter"

on page 7-21, averages the sample values, and adjusts the

AGC value at the end of the scan.

Raster scanning is useful when symbols vary in placement and a single scan line cannot be counted on to cross the symbol, and for reading stacked symbologies such as PDF417.

The user can enable raster scanning and adjust the raster sweep limits and the sweep rate.

Raster Status

Definition:

When disabled, the raster mirror will park at the top of the raster sweep.

Serial Cmd:

<

K506,raster status

,top offset,bottom offset,raster sweep rate,read cycle on/off>

Default:

Enabled

Options:


Note: Raster sweeps are only counted during a read cycle (continuous, triggered, and read rate). Raster sweeps are NOT counted when the raster motor is parked, disabled, set to straight line operation (top and bottom are equal), or when performing a self-calibration.

Raster/Laser

Raster Sweep Rate

Usage:

Definition:

If your application allows it, a slower sweep rate can produce more scans per second and higher read rates. To determine the minimum

read rate for your application, see

"Raster Picket Fence Calculation"

on page A-21.

The raster sweep rate is the number of sweeps per second the raster mirror completes. A sweep is one pass of the raster, up or down. The maximum sweep rate is limited by the size of the arc the raster must move through.

Serial Cmd:

<

K506,

raster status,top offset,bottom offset,

raster sweep rate

,read cycle on/off>

Default:

Options:

0 to 80.

To maximize the number of scans per symbol, use the lowest effective sweep rate required for the application.

Important

: The MS-860 is physically different from the MS-850 in trigger polarity and the calculation of raster sweeps.

Read Cycle On/Off

Usage:

Definition:

This feature should only be used when the raster sweep rate is at least twice the required trigger rate (decoded outputs per second).

When Read Cycle On/Off is enabled and Laser On/Off is also enabled, the raster mirror stops at top offset at the end of triggered read cycle.

Usage:

Must be enabled when reading characters outside the standard character set (0-9, A-Z, etc.)

Definition:

User must know in advance whether or not to use Full ASCII Set option.

Since Full ASCII Set requires two symbol words to encode one character, it is less efficient.

Standard Code 39 encodes 43 characters; zero through nine, capital “A” through capital “Z”, minus symbol, plus symbol, forward slash, space, decimal point, dollar sign and percent symbol. When Full ASCII Set is enabled, the reader can read the full ASCII character set, from 0 to 255.

Interleaved 2 of 5

Usage:

Definition:

It is has been popular because it is the most dense symbol for printing numeric characters less than 10 characters in length; however, we do not recommend this symbology for any new applications because of inherent problems such as truncation.

A dense, continuous, self-checking, numeric symbology. Characters are paired together so that each character has five elements, two wide and three narrow, representing numbers 0 through 9, with the bars representing the first character and the interleaved spaces representing the second character. (A check digit is highly recommended.)

Important

: You must set Symbol Length in order to decode I–2/5 symbols.

Symbol Length #1

Usage:

Definition:

With I–2/5, two symbol lengths can be defined. When using only one symbol length in an application, setting Symbol Length #2 to 0 (zero) to ensure data integrity is recommended.

Allows user to define the symbol length. Because I–2/5 is a continuous symbology, it is prone to substitution errors. Hence, a symbol length must be defined and a symbol must contain an even number of digits.

Note: If start, stop or check digits are used, they are not included in the symbol length count.

Since I–2/5 characters are paired, symbol length must be set to an even number. If Check Digit is enabled, add 2 to your symbol length. For example, if your symbol is 10 characters plus a check digit, then enable

Symbol Length for 12.

Note: Typically, when printing an I–2/5 symbol with an odd number of digits, a 0 will be added as the first character.

Options:

0 to 128

Important: When setting Symbol Length to any number other than 0, add 1 to account for a reserved space. For example, if your symbol has 3 characters, set Symbol Length to 4.

A supplemental is a 2 or 5 digit symbol appended to the main symbol.

When set to Enabled or Required, the reader reads supplemental symbol data that has been appended to the standard UPC or EAN codes.

Serial Cmd: <

K473,

UPC status,EAN status,

supplementals status

,separator status,separator character,supplementals type,UPC-E output as UPC-A>

Default:

Disabled

Options:


Disabled

UPC Supplementals will not be decoded.

Enabled

When enabled, the reader will try to decode a main and a supplemental. However, if a supplemental is not decoded, at the end of the read cycle, the main will be sent by itself. The UPC main and supplemental symbols are considered to be one symbol and will be treated as such.

Required

When set to Required and either the main or supplemental symbol is not read, a single noread condition results. The UPC main and supplemental symbols are treated as one symbol.

For example, if Supplementals is set to Required, Separator is enabled, and an asterisk is defined as the UPC separator character, then the data will be displayed as:

MAIN * SUPPLEMENTAL.Note: Under no circumstances will supplemental symbol data be sent without a main symbol.

Note: If additional symbols—other than the main or supplemental—will be read in the same read cycle, Number of symbols should be set accordingly.

Separator Status

Note: UPC must be enabled for EAN to take effect.

Serial Cmd:

<

K705,symbol output status

,when to output>

Default:

Good Read

Options:

0 = Disabled

1 = Match

2 = Mismatch

3 = Good Read

Note: If set to Match or Mismatch, Symbol Output Status will not take effect unless

Matchcode Type is enabled and a master symbol is loaded into memory.

Disabled

Usage:

Definition:

Useful when an application only needs to use the discrete outputs and can allow the reader to do the decision-making. When Disabled, the host does not need the symbol data and the communication lines are used only for setup and status checks.

When set to

Disabled

, the reader will not transmit any data that is generated during a read cycle (symbols, noreads, etc.).

Match

Usage:

Definition:

Match is used in an application that requires specific symbol information and needs to sort, route or verify based on matching the specific symbol data.

When set to

Match

, the reader transmits symbol data whenever a symbol matches a master symbol. However, if Matchcode Type is Disabled, it transmits on any good read.

Note: A noread can still be transmitted if Enabled.

Mismatch

Usage:

Definition:

Mismatch is typically used as a flag within the host system to prevent an item from being routed in the wrong container.

With

Mismatch

enabled, the reader transmits symbol data whenever the symbol data information does NOT match the master symbol.

Note: A noread can still be transmitted if enabled.

10-4


I/O Parameters

Good Read

Usage:

Definition:

Good Read is used when an application requires all symbol data to be transmitted. It’s typically used in tracking applications in which each object is uniquely identified.

With

Good Read

enabled, the reader transmits symbol data on any good read regardless of Matchcode Type setting.

Note: A noread can still be transmitted if enabled.

>

Default:

As Soon As Possible

Options:

0 = As Soon As Possible 1 = End of Read Cycle


Usage:

Definition:

As Soon As Possible is useful in applications in which symbol data needs to be moved quickly to the host, typically when the host is making decisions based on symbol data.

Enabling


causes symbol data to be sent to the host immediately after a symbol has been successfully decoded.

Note: More than one decode might in fact be required to qualify as a good decode, depending on how Decodes Before Output is set.


Note: See

"End of Read Cycle"

on page 7-14 for options to end the read cycle.

Usage:

Definition:

End of Read Cycle is useful in timing-based systems in which the host is not ready to accept data at the time it is decoded.

Enabling


means that symbol data does not get sent to the host until the read cycle ends with a timeout or new trigger.

Host activates trigger

Read Cycle

This is when host expects output

10-6


I/O Parameters

Noread Message

Usage:

Definition:

Used in applications where the host needs serial verification that a symbol has not been read and especially useful in new print verification.

Good Read (Green Flash)

Green flash LEDs will flash for less than one second when a good read condition is meet or when matchcode is enabled and a match occurs.

Static Presentation (Green Flash)

Static Presentation is used in conjunction with Continuous Read mode.

When operating in Static Presentation mode, whenever the EZ trigger is pressed, the reader will search for a symbol in Continuous Read mode. When a symbol is placed in the FOV and a good read occurs, the green LED will illuminate and stay on for the duration of time set in Green Flash Duration.Only one read will occur during that time unless more than one symbol is enabled in Number of Symbols.

Note: If Static Presentation mode is selected but the reader is not in Continuous

Read, Green Flash Mode will revert to the default Good Read.

To use Static Presentation:

1. Enable Continuous Read (see

"Trigger"

on page 3-6).

2. Select the number of symbols (see

"Multisymbol"

on page 7-4).

3. Enable Static Presentation in Green Flash Mode.

4. Select the read time in Green Flash Duration (see

"Green Flash Duration"

on page 10-11).

Serial Verification

Serial Verification

Usage:

These commands are useful in removing any doubt about the reader’s acceptance and response to host configuration commands.

For example, if the current preamble is “SOM” and

<Kd1, START>

is entered, the reader will echo back

<Kd1, SOM>

since the attempted entry “START” exceeds the four character limit for that command. Therefore it is rejected and the existing “SOM” message is echoed back and remains the preamble message.

Allows the user to verify configuration command status.

Definition:

Serial Command Echo Status

Important Note:

ESP will not function whenever this command is enabled.

Definition:

When enabled, a configuration command received from the host is echoed back to the host with the resultant settings.

Host

Reader

Function:

If a command with multiple fields is processed, some of the fields may have been processed properly while others were not. The changes will appear in the string echoed back so that the user will know which fields did or did not change.

I/O Parameters

Serial Command Beep Status

Important:

ESP will not function whenever this command is enabled.

Usage:

Definition:

Function:

Used to audibly verify the acceptance and validity of a command.

Causes the reader to beep once whenever a K command is entered to indicate that the command was accepted and processed.

If an invalid command is entered, the reader beeps 5 times to indicate an invalid entry. However, this does not necessarily mean that all data fields have been entered incorrectly. Only one bad field needs to be found in order to activate the 5 beep response.

When set to Disabled there is no effect on operation.

Reset Counts

Usage:

Definition:

Primarily used in test mode. Can also be used to reset counters daily.

When set to Reset Counts, a transition to the active state of the input will cause the reader to reset the internal counters (See

"Read Rate"

on page 15-3).

Unlatch Output

Definition:

This setting is used in combination with any of the three discrete outputs

that are in Unlatch Mode 1 (see

"Latch Mode 1 (Unlatch on Input

#1)"

on page 10-18). A transition to the active state will clear any of the three outputs that were previously latched.

I/O Parameters

Trend Analysis

Tracks the occurrences and frequency of mismatches, noreads, and the number of decodes per trigger and output the results to output 1.

Disabled

No output.

Diagnostic Warning

Activates output 1 when a diagnostic warning condition is met. When enabled the Out-

put State and Pulse Width settings (

<K810>

pulse, latch...) have no affect on output. The output will remain active as long as one of the diagnostic warning conditions persists. The output will go inactive whenever the warning condition no longer exists.

The output remains active as long as one of the diagnostic conditions is met.

Definition:

This is the default mode of operation in which the programmable output is activated when the Output On condition has been met and held active for the duration of the selected pulse width.

Latch Mode 1 (Unlatch on Input #1)

Definition:

The programmable output goes active when the Output On condition is met and will remain active until the state of input #1 changes from inactive to active.

Important

: To unlatch using the EZ Button the button’s status must be set to unlatch mode. (See

"Unlatch Outputs"

on page 3-6.)

Latch Mode 2 (Unlatch Opposite Condition)

Definition:

The programmable output goes active when the Output On condition is met and will remain active until the opposite condition selected under

Output On occurs.

For example, if Noread is enabled under Output On, the programmable output will go active upon a noread and remain active until the opposite condition, a good read, occurs.

Latch Mode 3 (Unlatch Enter Read Cycle)

Definition:

The programmable output goes active when the Output On condition has been met and is held active until a new read cycle begins.

NOTE: All of the Output On modes are suppressed when any Output on Warning is active for Output 1 (see

<K780>

command).

I/O Parameters

Trend Analysis (Output 1)

Usage:

Definition:

Example:

Useful in cases in which the user doesn’t want to shut down for a single condition but wants to monitor quality and read conditions.

Applies trend analysis settings to Output 1.

With Trend Analysis, the user can track the occurrences and frequency of mismatches, noreads, and the number of decodes per trigger and output the results to any of three outputs.

Trend analysis mode = Noread

Number to Output On = 4

Number of Triggers = 25

In this example, the reader will activate an output whenever 4 noreads occur within 25 triggers (read cycles).

With the exception of “Service threshold”, diagnostic outputs remain active as long as the diagnostic condition is detected.

I/O Parameters

Quality Output

Usage:

Definition:

Host system can monitor scanning performance (printing process, scanning environment changes, etc.) by setting thresholds in their processing or displaying the outputs for visual verification.

Allows the host to track the number of good reads per trigger by appending a five digit numeric field to the end of symbol data.

When enabled, symbol data is followed by a separator, followed by the five digits in the form of 00000. For example, a certain symbol that has been averaging 00100 decodes per read cycle suddenly drops to 00012, this would be a good indication that a problem has arisen even though good reads are still occurring.

Example

Assume a symbol with the data “HELLO” is read using database number 3 and the separator is set to space. The data output would be “HELLO DB03” assuming no other outputs or formatting were enabled. It is important to note that if the symbol is read with more than one database setting, the database number output will be associated with the first time the symbol is read.

10-26


I/O Parameters

Symbol Position Output

The location and in some cases the size of a decoded symbol can be determined dynamically. When enabled, raster height and scan locations relative to the reader are calculated and appended to the symbol data output. In most linear symbologies, the actual width of the symbol is added to the scan line location.

Raster Status

Usage:

Definition:

Locates the decoded symbol in the raster position.

Locates the decoded symbol in the raster position (RP).

The raster position is a 3-digit number from 0 to 255 indicating the height of the raster line with 0 at the top when the reader is in the upright position as shown here.

Serial Cmd: <

K758,raster status

,scan status,separator>

Default:

Disabled

Options:


When enabled the location of the symbol within the raster pattern is appended to the symbol data output, with a separator. The raster position is formatted with a leading identifier of “

RP

” and the number is a zero padded 3 digit number in the form of

RPXXX

.

The raster location value corresponds to the configurable raster offsets in the

<K506>

command in

"Raster Setup"

on page 8-3.

Example

For example, assume a symbol with the data “HELLO” is read when the raster is at an offset of 053, and the separator is set as a space.

The data output would be “HELLO RP053” assuming no other outputs or formatting is enabled.


10-27

Symbol Position Output

Scan Status

Usage:

Definition:

Locates the decoded symbol in the scan position.

Locates the decoded symbol in the scan position

(SP).

The scan position is a 3-digit number from 0 to

100 indicating the nearest point from the upper or lower extremity of the symbol to the nearest edge of the entire scan width.

Serial Cmd: <

K758,

raster status,

scan position

,separator>

Default:

Disabled

Options:


When enabled the location of the symbol within the scan line is appended to the symbol data output, with a separator. The scan position is formatted with a leading identifier of

“

SP

” plus two zero-padded three digit numbers (corresponding to the first and last bar of the symbol for most symbologies), separated by a colon in the form of:

SPXXX:YYY

The scan position values correspond to the configurable laser on/off position values in the

<K700>

command.

XXX

is the position of the first bar of the symbol

YYY

is the position of the last bar, the ranges being 0 to 100.

Note: the scan width data is calculated from the beginning of the full scan width, not the partial or auto-framed width.

Example

Assume a symbol with the data “HELLO” is read when its first bar is at 20% of the scan width. The width of the symbol is 13% of the scan line

The data output would be “HELLO SP020:033” assuming no other outputs or formatting is enabled.

Timing

Position information is from the first decode of the symbol.

Symbol position from subsequent decodes of the same symbol is ignored.

Raster position

Location of raster when symbol was decoded the first time.

Location of symbol within the scan line of the first decode.

Scan position

Position values may come from different scans and symbols:

Main symbol: First decode.

Supplemental: The scan in which both the main and supplemental are decoded.

When both symbols decode in the same scan line.

Position values are averaged over several scan lines in which a codeword is decoded.

Position values are for the last scan which allows the symbol to fully decode.

Position values may be mixed from either the linear or 2D component, and may come from different scans.

The most extreme position (closest to the top or bottom of the raster pattern) of either the main or supplemental.

Location of the raster when the symbols were decoded.

The average raster position will correspond to the approximate

“middle” of the symbol.

The position of the raster when the symbol fully decodes.

The most extreme position (closest to the top or bottom of the raster pattern) of either the linear component or 2D component.

The most extreme position (closest to the edge of scan) from either the main or supplemental.

First bar and last bar position values may come from different symbols and scans.

Note: At least one position value is from the first decode of the main symbol. The other two values may be from the supplemental. There is no indication as to which position value corresponds to which symbol, but some assumptions can be made if the symbols are moving in a ladder orientation.

The most extreme position (closest to the edge of scan) from either the main or supplemental.

First bar and last bar position come from different symbols but the SAME scan.

Average first and last bar position.

Note: If the symbol is moving “fast”, position information may tend to “converge” toward the middle of the raster pattern and scan line. First and last bar positions will not correlate to row width.

These symbologies can sometimes be decoded even when the scan line does not cross all elements in one sweep. Therefore, the position information corresponds to the position of the last scanned element that allows the symbol to fully decode.

This is a single point, and therefore, the scan position data is the same for both the first and last bar. Example: SP043:043.

The most extreme position (closest to the edge of scan) from either the linear component or 2D component. First bar and last bar position values may come from different symbols and scans.

If both the linear and 2D component are both single-point scan positions (example: RSS+

MicroPDF), then the net scan position will also be a single point.


10-29

Read Duration Output

Read Duration Output

Definition:

When enabled the duration (in milliseconds) from when the read cycle started until the symbol data is output is appended to the data with a separator. It is important to note that when in level mode if the user wishes to measure the entire length of the trigger pulse the user needs to set the When to Output Symbol Data to End of Read Cycle. This will prevent the read duration from being shorter than the entire read cycle in the event you qualify the symbol requirements for output before the trigger becomes inactive. This output has the capability of measuring over

49 days worth of duration, if exceeded the message “OVERFLOW” will be output in place of the duration.

Matchcode

Overview of Matchcode

Usage:

Definition:

Matchcode is used in applications to sort, route, or verify data based on matching the specific symbol in a variety of ways as defined in this section. For example, a manufacturer might sort a product based on dates that are embedded in the symbol.

With Matchcode you can store master symbol data in the reader’s memory, compare this data against the scanned symbols, and define how symbol data and/or discrete signal output will be directed. A master sym-

bol database can be set up for up to 10 master symbols. See

"Master

Symbol Database"

on page 15-8.

Using Master Symbols

1. Set Triggering Mode to

External

or

Serial

(see

"Trigger Mode"

on page 7-6).

2. Chose the method of symbol comparison that fits your application (see

"Matchcode

Type"

on page 11-4).

3. Define the output you want with your matchcode setup:

a) Symbol output (

"Symbol Data Output Status"

on page 10-4).

b) Discrete output (see Chapter 10,

"I/O Parameters"

).

4. Select the number of master symbols you want to create, if more than one (see

"Number of Master Symbols"

on page 15-9).

5. Enter master symbol data in one of the following ways: a) Use ESP to type in master symbol data directly into the Utilities menu.

b) Send a serial command with symbol data in the form of

<Mmaster sym-

bol#,data>

(or

<)data)>

for single master symbol only). c) Send a

<Gmaster symbol number>

command to scan next symbol in as the master symbol.

d) Enable the

New Master Pin

command and activate a discrete input to store

the next symbol scanned as the master symbol (see

"Sequence Step"

on

page 11-11).

See also


on page 15-9 for more information details on entering, requesting, and deleting master symbols.

Matchcode

Sequential Matching

Usage:

Definition:

Useful in tracking product serial numbers that increment or decrement sequentially.

With Sequential enabled, Sequential Matching determines if a count is in ascending (incremental) or descending (decremental) order.

Serial Cmd:

<

K223,

Default:

Increment

Options:

0 = Increment 1 = Decrement


11-5

Match Start Position

Match Start Position

Usage:

Definition:

Match Start Position is useful in defining specific portions of a symbol for comparisons. For example, if a symbol contains a part number, manufacturing date, and lot code info but the user is only interested in the part number information, Match Start Position can be set to only sort on the part number and ignore the rest of the characters.

Match Start Position determines the portions of symbols that will be matched by defining the first character in the symbol (from left to right) that will be compared with those of the master symbol, when Matchcode

Type is set to Enabled or Sequential.

Function:

For example, if Match Start Position is set to 3, the first 2 characters read in the symbol will be ignored and only the 3rd and subsequent characters to the right will be compared, up to the number of characters specified by Match Length.

Wild Card Character

Wild Card Character

Usage:

For example, with Wild Card Character defined as the default asterisk, defining

CR*34

as the master symbol will result in matches for CR134,

CR234, but not CR2345. Entering the wild card at the end of the master symbol as in

CR***

will result in matches for variable symbol lengths such as CR1, CR23, CR358, etc. provided that the number of wild card characters matches or exceeds the number of characters present.

Definition:

Wild Card Character allows a user to define a wild card character as part of the master symbol.

Sequence On Noread

Usage:

Definition:

Sequence On Noread is useful when the reader needs to stay in sequence even if no decode occurs.

When Sequence On Noread is Enabled and Matchcode is set to

Sequential, the reader sequences the master symbol on every match or noread. When disabled, it does not sequence on a noread.

Matchcode

Sequence Step

Usage:

Definition:

Useful in applications in which it is desirable to count by intervals other than 1.

Sequencing in Matchcode operations can occur in steps from 1 to

32,768.

Sequencing performs like a mechanical counter by displaying positive integers and a specific number of digits after roll-overs. For example, 000

– 3 = 997 (not –3) and 999 + 3 = 002 (not 1002).

Serial Cmd:

<

K228,sequence step

>

Default:

1

Options:

0 - 32768

New Master Pin

Usage:

Definition:

Some applications require the line worker to change the master symbol.

This can be done by installing a switch at the location of the reader. It is very common to have a keyed switch so that accidental switching does not occur.

After New Master Pin is enabled, a pulse can be received on the new master pin which will cause the reader to record the next decoded symbol(s) as the new master symbol(s).

It is important to note that the enabling New Master Pin does not in itself cause a master symbol to be recorded. The master pin must then be activated momentarily (for a minimum of 10 mS) before a master

symbol can be scanned into memory. (See

"Electrical Specifications"

on page A-4.)

Serial Cmd:

<

K225,status

>

Default:

Disabled

Options:


After New Master Pin has been enabled and the pin activated, decodes will be saved in the master database beginning with master symbol #1. If the reader is configured for a multisymbol read cycle (Number of Symbols is greater than 1), the remaining decodes will be saved in each consecutive master symbol location. For example, if

Number of Symbols is set to 3 and New Master Pin is then activated, at the end of the next read cycle, the decoded symbols will be saved as master symbols 1, 2, and 3.

Diagnostic Messages Overview

Usage:

Definition:

These messages serve as a flag to service a scanner or as an early warning that potential problems could arise. They are particularly useful in factories that run 24/7 and can’t afford down time.

Warning messages that relate to the environment and condition of the scanner can be defined and set to activate specific outputs.

Note: When enabled, the error condition will override all other operational modes configured for the output.

When enabled, laser current and NOVRAM warning messages will be transmitted to the host or any active port whenever the pre-defined conditions are met.

Output Format

Output Format Overview

Output Format consists of a set of criteria expressed in Extraction and Insertion serial or ESP menu commands that can be chained together to control the presentation of data that is transmitted from decoded symbols. If a symbol does not meet the defined criteria, it is treated as a noread.

Note that Extraction and Insertion functions are independent of Ordered Output criteria. The output format control can also work with all standard read modes such as

Matchcode, Multisymbol etc.

Commands can be chained together in an array of as many as 100 steps and applied to any symbol.

Output Format Status

Definition:

ESP:

Output Format Status is a “master switch” that controls Output For-

mat. Extraction and/or Insertion commands must be defined before an output occurs.

When you set up Output Format in the ESP Output Format menu and click on Apply in the same menu, Output Format Status will be changed to Enable in the reader and displayed as such in the Outputs configuration menu after you send a Retrieve Reader Settings command.

You can also enable/disable Output Format from the Outputs menu by double-clicking on Output Format.

Serial Cmd:

<

>

Default:

Disabled

Options:


Note: Output Format Status must be enabled in order for any Output Format commands to function.

Inserts up to four characters at a time into a data output string. You can add additional characters by repeating the procedure.

Insertion by ESP

Up to 4 ASCII characters can be inserted at any point in symbol input and added to the output. After scanning a symbol and selecting the original characters for extraction, as

shown in

"Extraction by ESP"

on page 13-4, do the following:

1. Click

Insert.

2. Type in text to be inserted or select ASCII character from the ASCII selector and click

OK

.

(A zero disables Length or can mark the end of a format cell array.)

0 to 4 (0 is disabled)

Hex String

Definition:

A pair of hex digits represent an ASCII character. Each pair of hex digits ranges from 00 to FF. Each hex string has a maximum of 4 pairs.

For example, hex 65 = ‘e’, 6e = ‘n’, 64 = ‘d’, thus 656e64 = “end”

Serial Cmd:

<

K741,

output #,length,

hex string

>

Default:

00

Options:

00 to FF

Output Format Examples by Serial Command

A symbol with the data

ABCDEFGH

needs to be manipulated to output:

DEFGH@$ABCend

.

The following commands are sent to achieve this setup:

<K740,1,4,5>

for extraction mode, output# =1, start position = 4, length = 5.

<K741,2,2,4024>

for insertion mode, output# = 2, length = 2, hex string = 4024.

Note that the hex pairs 40 and 24 = @$ in ASCII.

<K740,3,1,3>

for extraction mode, output# = 3, start position = 1, length = 3.

<K741,4,3,656e64>

for insertion mode, output # = 4, length = 3, hex string =

656e64

Note that 656e64 = “end”.

<K741,0>

This ends the sequence and could have been done with a 740 command, as well.

Special Rules for Using Multisymbol with Output Format

1. Unless you want to assign output formatting to more than one symbol at a time in your multisymbol sequence, disable all symbols except the one to which you are applying the output formatting.

2. The 12 symbols in Multisymbol Output Format Status correspond to multisymbols; the 12 filters in Ordered Output apply only to the order of output and have no relationship to Multisymbol or Symbol Output Format Status.


13-9

Ordered Output

Ordered Output

Usage:

Definition:

Useful in sorting several symbols into multiple categories with specific fields and a defined order of output.

Ordered Output involves filtering and ordering.

In the filtering stage, each symbol in a read cycle is read and matched against a user-defined database of up to 12 filters which search on symbology type, symbol length and data contents. A given symbol must meet all three criteria in any one of the filters in order to be included.

In the ordering stage, symbols are transmitted in the order that they match up with the filters. A symbol matching filter #1 will transmit first, another matching filter #2 will transmit next, and so forth.

Rule #1

Each symbol decoded must match one of the filters before it can be saved to a read cycle record. However, an exception exists whenever the number of symbols required for a read cycle exceeds the number of active filters. In this case, unfiltered symbols can be placed into unfiltered output positions. For example, if the number of symbols required is 6 but there are only 4 active filters, the last 2 positions can be filled by any

(un-filtered) qualified symbol.

Rule #2

The user can use the same filter setup multiple times. For example, if filters 1, 2, & 3 are setup to filter on Data Matrix symbol type and in the order that they are decoded, qualified Data Matrix symbols will be output in filters 1,2 & 3 positions.

Rule #3

All qualified symbols will be sorted and output in the filter position they match. If a symbol matches filter 3, it will be output as the 3rd symbol. If a filter does not have a symbol qualified for it, a NOREAD message will be output in place of the symbol (if

Noread message is enabled). For example, if filter 3 does not have a symbol that meets it's requirements, a NOREAD message will be output in the 3rd output position.

Wildcard/Placeholder Matches


You can regard wildcard marks as the end of matching, whereas a placeholder requires identical data both before and after the placeholder.

For example:

Filter data “

123*

” matches “123”, “123456”, “123ABC” but not “12”.

Filter data “

123*AB?C

” will be interpreted as “123*”

Filter data “

123?A?

” matches “1234AB”, “123BAT”, but not “1234A” or “123BATS”.

Filter data “

12??*

” matches “1234”, “123456”, “123ABC”, but not “12”, “123”.

Filter data “

123?A*

” matches “1234A”, “123BA”, “123BATS”, but not “1234”, “1234C”.

<K745,3>

enables Output Filters #1 to filter #3’s setting.

<K745,0>

disables all output filters. The reader will not perform any filtered output.

Examples to enable and setup filters 1 and 2:

Filter #1

Symbology type = Code 39, Length = disabled, Wildcard = ‘*’, placeholder = ‘?’, data = “AB*” = 41422A

<K744,1,3,0,2A,3F,41422a>

Filter #2

Symbology type = Code 128, Length = 8, Wildcard = ‘*’, placeholder = ‘?’, data = “NBC??FGH” = 4e42433f3f464748.

<K744,2,4,8,2A,3F,4e42433f3f464748>

<K745,2>

enables Ordered Output. It also enables filter index1 and filter index2.

Let’s say we have four symbols, “NBCXYFGH”, “NBDXYFGH”, “123XYZ”, “ABCDE”. The reader will registered two good reads only and transmit the following:“ABCDE”, “NBCX-

YFGH”.

Utility commands are generally commands that are performed during reader operations to check read rates, determine read rates or perform miscellaneous operations on reader hardware. Serial utility commands are not prefaced with a “K” and a numeric code, nor do they require an initialization command (

<A>

and

<Z>

). They can be entered from within any terminal program or from within ESP in the Terminal window.

Note on Serial Commands: To preserve continuity with other Microscan products, some serial configuration commands may include 0s (zeros) or 1s as placeholders. In order for a these commands to be implemented, the placeholder values or commas must be included.

Utilities

Read Rate

When in a read rate mode, the reader will output a number preceding the symbol data. This number will represent either the number of decoded scans per second or the percentage of successful decoder per total number of scans.

Make a note of the decode rate. It will be a useful reference when calculating the number

of decodes. (See

"Formulas for Number of Decodes"

on page A-20.)

Read Rate by ESP

You can access Read Rate from the Utilities menu. To start or end a read rate test, right-click

Read Rate

and select

Start

or

Stop

.

To change from percent read rate to decodes per second, first end the read rate by selecting

Stop

, then right-click and select

Decodes/Sec

.

Read Rate by Serial Command

Enter Single Symbol Decodes/Second Test

Sending

<C>

instructs the reader to transmit the decodes per second and symbol data

(if any). The decode rate can vary dramatically due to the angle and location of the symbol in relation to the scan line. This test is very useful in aligning and positioning the scanning device during installation.

Enter Single Symbol Percent Test

Sending

<Cp>

instructs the reader to transmit the percentage of decodes and any scanned symbol data.

Extended Read Rate

Sending

<Ce>

instructs the reader to transmit the decodes per second along with the transitions, scan position, and raster position.

Note: The

<Ce>

command has no immediate effect if not preceded by

<C>

or

<Cs>

.

End Read Rate Test

Sending

<J>

ends both the Percent test and the Decodes/Second test for both single and multi-symbol. Sending a

<J>

will end the read cycle.

Counters

Counters

Counter commands can be a numeric value from 00000 to 65,535. After reaching the maximum numeric limit of 65,535, the counter will automatically roll-over and start counting again at 00000 and report any errors. To obtain the cumulative total of counts after the roll-over has occurred, add 65,536 per each roll-over (the reader does not keep track of the number of roll-overs) to the current count.

Note:

All counter values will be lost if power is re-cycled to the reader or the reader receives a reset or save command.

Counters by ESP

You can access Counters from the Utilities menu.

Right-click

the appropriate counter option and select

Request

to display count or

Clear

to set counter to zero. Or, right-click on

Digital Bar Code

Digital Bar Code

When you click the

Digital Bar Code

tab and the

Start

button, a digitized representation of the symbol in front of the reader will appear.

This routine is useful for conveying a sense of the symbol’s readability and graphically indicating bad or unreadable portions of symbols, extraneous “noise,” etc. A green waveform indicates a decoded symbol; a red waveform indicates an undecoded symbol or other object.

The read triangles represent the width of the scan beam relative to the symbol. The upward pointing arrows indicated the symbol’s margin.

Zoom In, Zoom Out

You can zoom in by sliding the

Zoom

lever to the right. You may have to scroll right or left to locate your symbol, but the results will be striking.

Optoisolator Outputs

Optoisolator circuits can transfer pulses between the reader and peripherals with no direct connection with the reader’s internal circuitry. However, not every optoisolator configuration provides complete isolation. The following diagrams show both fully optoisolated and non-optoisolated circuits. They are only examples and do not represent all the possible wiring configurations.

Serial Command Format

Appendix D — Serial Command Format

Serial commands are of two types: utility and configuration.

Rules that apply to both utility and configuration commands

• A less than

<

and greater than

>

characters enclose the commands unless non-

delimited commands are used. (See

"Trigger Mode"

on page 7-6.)

• Commands and data are “case sensitive.” That is, characters must be entered as upper or lower case, as specified.

Serial Utility Commands

These are sent during operations and are not followed by

<A>

or

<Z>

.

Serial Configuration “K” Commands

These begin with a single K character followed by a three digit numeric, a comma, data fields separated by commas, and typically, an initializing command, as follows:

<

K

three digit numeric,data,data,...etc.><initializing command>

1

An initializing command of type “

A

” (not saved to non-volatile memory) or type “

Z

”

(saved to non-volatile memory) may follow the command.

For example, to enable UPC and save the change for power-on, send:

<K473,1><Z>

.

To change Baud Rate and reset without saving changes for power-on, send

<K100,3><A>

.

Serial Configuration Command Conventions:

• All data fields (except the last) must be followed by a comma (without a space).

• The following characters cannot be used:

,

<

,

>

, and

NULL

.

• All fields preceding a modified field must be included.

• If there is no change in preceding fields, then commas alone can be entered in these fields. For example, if only the last field in the following command is changing,

<K100,4,1,0,0>

can be entered as

<K100,,,0>

.

• All fields following a modified field can be omitted. For example, to change Baud

Rate, send

<K100,3>

.

1. In many commands a K command will automatically be saved for power-on with the MS-860.

A-12


Appendices

Concatenating Configuration Commands

Commands can be concatenated (added together) in a single string or data block.

Serial Command Status Request

To ensure that any command was received and accepted, you can send the Show

Reader Status command:

<?>

.

The status of a specific serial command can be requested by entering the command followed by a question mark, for example

<K101?>

. To see all K commands, send a

<K?>

command.

With the MS-860, each K command is framed with a preamble and postamble and may be mixed with bar code symbol data. To prevent this, send an



command to disable scanning before sending the K request. Follow the K request with an

<H>

command to restore scanning.

Entering Special Characters in Serial Commands


Entering Special Characters in Embedded Menus

Control Characters


<CR><LF><NUL><NUL>

.

Press

SP

(the space bar) once, then enter the control character by holding down the control key and simultaneously pressing the desired character. For example to define a line feed, press

SP

, then

Control

and

J

simultaneously. It is displayed as

^J

on the command line and as

<LF>

in the menu when the screen is refreshed.

To Define a Carriage Return as a Character

Press

SP

, then

CR

. It is displayed as

^M

on the command line and as

<CR>


To Define a Space as a Character

Press

SP

twice. It is displayed as a blank space in the menu when the screen is refreshed. While it appears that nothing has been assigned, the hex value 20 will be sent during data transmission.

To Select NUL as the Character

Press

SP

, then a

0

(zero). It is displayed as

<NUL>

Defaulting/Saving/Resetting

Appendix F — Defaulting/Saving/Resetting

Understanding and controlling your reader’s active, saved, and default settings is critical to the operation of your reader.

Software Reset/Save/Recall Commands

<A>

Reset (does not save for power-on)

<Ard>

Reset and recall Microscan defaults

<Arp>

Reset and recall power-on parameters

<Arc>

Reset and recall customer default parameters

<Z>

<Zc>

Save current settings for power-on

Save current settings as customer default parameters

<Zrd>

Recall Microscan default parameters and save for power-on

<Zrc>

Recall customer default parameters and save for power-on

Power-on Parameters

Power-on parameters (saved by the

<Z>

command) are saved to NOVRAM and recalled and loaded into current parameters when power is cycled or the

<Arp>

command is issued.

Customer Default Parameters

Customer default parameters (saved by

<Zc>

command) are the same set of parameters as power-on but are saved in a different, isolated section of NOVRAM. This can allow a user to essentially create a backup set of parameters that can be recalled in the event that the current parameters or power-on parameters have been changed and no longer desired. It is important to note that a hardware default does not affect these parameters. For example, a user that inadvertently changed communication settings in power-on parameters in such a way that they either don't know the settings or don't have the capability to communicate at those settings. By using the hardware default to default the power-on settings to the known Microscan default, the user can then recall their previously customer saved settings with the

<Arc>

or

<Zrc>

commands.

Default on Power-On

You can also use the EZ button to default the reader to customer defaults and save for power-on by holding down the EZ button while applying power to the reader, provided

that this feature is enabled in

"Default on Power-on"

on page 3-7. This is the same as the

<Zrc>

command.

A-16


Appendices

Microscan Default Parameters

Microscan defaults parameters are contained in the firmware that cannot be changed.

Software Default

Microscan default parameters can be recalled (loaded into current settings) with

<Ard>

command or recalled and saved for power-on with the

<Zrd>

command.

Hardware Default

If a software default reset is not possible, it may be necessary to reset the reader by shorting (connecting) specific pins. This procedure has the same effect as the

<Zrd>

software command.

Important: For this reset to occur, this command must be executed within 60 seconds after a power-on or a reset.

1. Apply power to the reader.

2. Locate pins 7 and 11 on the host connector.

Caution: Be certain that the correct pins are located. Connecting the wrong pins could cause serious damage to the unit.

3. Momentarily connect these wires (or pins) and listen for a series of short beeps.

4. Within 3 seconds, connect them again. A longer beep should be heard. If not, repeat the process.

Default/Reset Definitions

Defaults are original or saved customer settings that can be recalled, either by software reset

<Zrd>

or hardware reset.

Also when in multidrop, defaulting might be required if the reader has been assigned a polling address and you wish to access the reader’s menu.

Defaulting the reader by

<Zrd>

resets the configuration parameters to Microscan default values. Defaulting might be necessary if you have make temporary changes, communications between the reader and another device are lost or interrupted, or you are using incompatible equipment (for example, a terminal that is set at 38.4K baud communicating with a reader that is set at 115.2K baud).

1

Resets (“

A

” commands) affect only the current settings (active memory) and are not saved for power on or recall.

Active Memory is where the reader’s active settings are stored during use. These are not available on power-on unless saved by a “

Z

” command.

1. There are no menu options or host commands for resetting the configuration program.


A-17

Symbol Configuration

Appendix G — Symbol Configuration

You can configure your reader by presenting Code 128 symbols that the MS-860 reader responds to as serial commands.

Note: Your reader does not need to be enabled for Code 128 in order to enter symbol configuration.

Entering Symbol Configuration

The symbol used to enter configuration is the 7-character code 128 symbol shown below. It is not required that the reader be configured to read code 128 symbols to read this start symbol or the following configuration symbols.

To setup for symbol configuration:

1. Put the reader in a read cycle mode.

2. Place a special Code 128 configuration start symbol in the readers field of view.

Use this symbol or one that you have created yourself.

If the reader is able to read the start symbol, it will begin to beep and the performance LEDs will be activated.

3. When the reader starts to beep, remove the configuration symbol from the reader’s field of view.

The beeping will end and the reader will be in the configuration mode.

During the configuration mode the LEDs will emit a side to side “Knight Rider” pattern to let you know you are currently ready to configure.

You can create your own start symbol by encoding the following in Code 128:

FNC4 <_CFG>

.

A-18


Appendices

Using Configuration Symbols

Once in symbol configuration mode, serial command data encoded in Code 128 symbols is read by the reader as serial input.

Configuration symbols must meet the following conditions:

1. The only valid configuration symbols are Code 128.

2. Symbol data may contain more than one command, but individual symbols must be presented one at a time. This is because only the first symbol in a read cycle record will be used as a possible configuration symbol.A symbol that is presented to the reader must be read 25 times consecutively to be used as a valid symbol.

Once this is done the reader will interpret the symbol data in the same fashion as it interprets serial data.

3. Any valid command may be entered via symbols including operational commands.

Because the data is treated like serial input multiple symbols may be used to represent one command as long as the symbols are presented individually and in the correct order.

4. Read rate command may also be used to enter read rate from symbol configuration mode.

5. When in read rate, the reader will read the symbologies that were enabled prior to entering the configuration mode. However it will read a “

<J>

” in code 128 regardless of current enable/disable state of code 128.

Once the

<J>

is issued the reader exit both read rate and symbol configuration.

To exit read rate and remain in symbol configuration, you present the start symbol once again. Symbols read in read rate will not configure the reader.

To start a read rate test, scan this symbol:

Exiting Symbol Configuration

There are multiple ways of exiting symbol configuration. The first way is to simply read or serially enter the “

<J>

” command. Other ways include any command that executes a software reset. These commands include the save family as well as the reset family e.g.

<Z>

,

<Zc>

,

<Zrd>

,

<Zrc>

,

<A>

,

<Arc>

and

<Ard>

. When exiting symbol configuration with the symbol “

<J>

,” the reader will beep in response.

To end the read rate test and the symbol configuration program, scan this symbol:

This will terminate symbol configuration mode. Changes made in configuration will remain in effect just as would changes made in the menus or by serial commands.


A-19

Formulas for Number of Decodes

Appendix H — Formulas for Number of Decodes

To ensure reliable scanning, apply a minimum of five decodes to each symbol. Use the formulas below to calculate the number of decodes that your symbol will receive.

If the number of decodes you derive from one of these calculations is less than the minimum for your application, plug in the minimum number of decodes (5) and solve for another parameter that might be changed, such as scan speed or scans per second.

Note: While the formulas given here solve for the predicted number of decodes, you may also use the formulas to solve for other parameters that might be changed, such as scan speed, symbol length, etc.

Single Line Ladder Calculation

For single scan line ladder scanning, use the following formula:

⎛

⎝

SS

⎠

= ND (number of decodes)

1

SH (Symbol Height) (ladder formula only) is a measurement of the height of individual bars.

SS (Scan Speed) is the distance per second that a symbol moves through the scan.

DR (Decode Rate) is the number of decodes per second that a given symbol receives (as derived from a stationary scan test).

Single Scan Line Picket Fence Calculation

Direction of label travel

Ladder

Scan Line

For single scan line picket fence scanning use the following formula:

⎛

⎝

(

SS

)

⎠

= number of complete decodes

Picket Fence

A-20

1. The -3 component in the formula is included to allow for AGC acquisition, an incomplete first scan, and an incomplete last scan. This applies only if the number inside the parentheses equals

4 or more. If the number equals 3, then only subtract 2 to derive 1 good scan.


Appendices

Raster Picket Fence Calculation

For raster picket fence scanning, the number of decodes (ND) that can be applied to a given symbol can be calculated once the sweep rate (SR) is known.

Sweep Rate (SR)

Sweep rate is the number of raster sweeps (up or down) that occur per second and can be set in ESP.

Since the sweep rate cannot exceed 30 you first need to ensure that your application can achieve this by solving for sweep rate. The sweep rate should generally be set as low as possible in order to maximize the number of scans on a given symbol.

The formula for determining Sweep Rate (SR) is as follows:

1

Direction of symbol travel

Raster pattern

Raster

Picket Fence

SR

=

( )

SR = Sweep Rate, the number of passes, up or down, that are described by the arc of the raster mirror.

SS = Scan Speed, the distance per second that a symbol moves through the scan.

SW = Scan Width, the width across the scan beam, at a given distance from the reader, in which a symbol can be read (picket fence formula only).

SL = Symbol Length, the length of the longest printed symbol to be read plus the length of the quiet zones (picket fence formula only).

Example:

SW = 5

SS = 2 inches per second

SR

=

(

2 2

)

= 1

SL = 1

Important: The maximum sweep rate that your can set the reader to is 80. If your solution is greater than 80, you must change another parameter such as scan speed, etc. and recalculate.

Since SR can only be entered into the software as whole numbers, round off fractions of

SR to the next higher number, for example enter 0.4 as 1 and 3.5 as 4.

In setting up the reader, raster height depends on the raster arc and the symbol distance (range) from the reader. Both the top offset and bottom offsets can be adjusted independently in 255 increments and the resulting arc can vary from 0° to 30°. (See

Chapter 8,

"Raster/Laser"

.)

1. The number 2 in the SR formula ensures that each symbol receives two full raster sweeps.


A-21

Formulas for Number of Decodes

Angled Picket Fence Calculation

The number of complete scans for angled picket fence is calculated the same as that for picket fence, with the exception that the scan width is shortened in proportion to scan tilt.

Direction of symbol travel

Scan Line

Angled Picket Fence

Improving the Number of Decodes

After changing any of the parameters described in this section, recalculate the number of decodes.

Scan Speed

Scan speed is a function of motor speed and is adjustable. A slower scan speed may allow greater symbol range and/or higher decode rates, but at the cost of fewer scans per symbol. Applies to both picket fence and ladder oriented symbols. If your application allows it, slowing scan speed (the time in seconds that a symbol is fully within the scan width of the reader) is an effective way to increase the number of decodes.

Range

Adjusting the symbol’s range, if possible, is one of the quickest and most effective ways to improve decode rates. However, in some applications you may need to select a less than optimum range, or one that is beyond the fringes of the ranges.

Scan Width

Increasing scan width will increase the number of scans in a picket fence oriented application. Scan width is linked with scan range and changing one will usually require a change in the other.

Symbol Dimensions, Symbol Density, and Symbol Ratio

Not usually an option in most applications, but changes to symbol parameters can affect number of decodes calculations and possibly decode rates.

If your application allows it, shortening the length of a picket fence symbol means the symbol will be in the scan range longer and hence receive a greater number of scans.

Increasing the height of a ladder symbol means it will receive more scans. Changing symbol density and/or symbol ratio is another way ranges, decode rates, etc. can be altered.

A-22


Appendices

Appendix I — Operational Tips

Do:

• Check inputs (scan speed, length, height, etc.) to ensure the desired number of decodes per symbol.

• Connect reader to host before connecting power to the reader; disconnect power before disconnecting the host from the reader.

• For optimum decodes, mount reader so that your symbols pass through the center of the depth-of-field (minimum/maximum range). You find the center by moving your symbol in and out during a read rate test.

• Avoid excessive tilt, pitch, and skew of the symbol.

• Check the symbol for readability by doing a decode rate test. If there is any question about the symbol's readability, contact your Omron representative.

• After changing any parameter that might affect decode rate, repeat decode rate test.

• Clean the reader window with a clean, dry Q-tip or cotton cloth on a regular basis.

Do Not:

• Aim the reader into direct light or sunlight.

• Aim the reader into an external object detector or other light-emitting device.

• Obstruct the reader window with mounting hardware or other objects.

• Connect chassis of reader and host to different ground potentials.

• Operate the reader in excessive temperature environments.


A-23

Embedded Menus

Appendix J — Embedded Menus

In addition to ESP, you can also use a communications menu such as Microsoft’s Hyper-

Terminal

™

to establish communication with Microscan’s embedded menus.

1

Because of size/space limitations of embedded menus, their structures and terms may not precisely match those of ESP or this manual.

1. With your host connected to MS-860, set your host communications settings as follows:

9600

baud,

7

Data Bits,

1

Stop Bits, and

None

Parity.

2. Set Flow Control to

None

.

3. Make the communications port selection. (Usually

COM 1

for Windows.)

Upon connection, send a

<D>

command to bring up the main menu.

Menu navigation commands are case sensitive. Use the space bar or

N

to advance to the next item,

CR

(return key) to select a highlighted item,

B

to return to the previous item,

M

to return to the previous menu, and

ESC

to return to the Main menu or to exit the program. When exiting the program, you will be prompted to save your active settings for power up (

Y

or

N

). Typing Y will be equivalent to saving with a

<Z>

command.

A-24

1. If you are using Microsoft’s HyperTerminal program, you may find that the initial screen is not visible when you call up the program with the

<D>

command. If this occurs, exit the embedded menu with a

ESC

,

E

, and

N

sequence and repeat the

<D>

command.


Appendices

Appendix K — Interface Standards

Interface Standards, established by the Electronic Industries Association (EIA), specify such things as the signaling voltage levels, maximum cable lengths, and number of drivers. With Microscan devices, selection of interface is made by pin assignment and, in the case of the host communications, by software switching between RS232 and

RS422. Microscan devices use RS232, RS422, and RS485 multidrop.

RS232

RS232 defines an interface between two devices, such as the reader and host. It differs from the other interfaces by dedicating individual pins to specific functions and by requiring both devices to share a common ground line. Since both device chassis are connected to a common ground, a ground loop potential and the possibility of noise interference exists; therefore, cable lengths are limited to a maximum of 50 feet

(19.7m). Despite being the most limited, this interface is used frequently because of the large installed base of RS232 equipment.

RS422

RS422, unlike RS232, measures signals deferentially; that is, the receiver looks at the potentials between the two receive (or transmit) wires rather than the potential between signal and ground. As a result, cables, if shielded, can be up to 4000 feet

(1219m) in length. Like RS232, RS422 communication is designed for only two devices on a single line and must have a common ground. It can be used wherever RS232 is used.

RS485

RS485, like RS422, can transmit up to 4000 feet (1219 m) using differential voltages, but unlike RS422, its transmitters are turned off until a request for data is received from the host. RS485 is used exclusively in multidrop protocol.

USB

The Universal Serial Bus can connect up to 127 devices to a host at a maximum of 6 megabits per second (Mbps) of bandwidth.


A-25

Multidrop Communications

Appendix L — Multidrop Communications

This appendix describes the rules for setting up a concentrator or controller to communicate with a reader in standard Multidrop protocol.

The diagram to the right shows a typical Multidrop network in which 1 to 50 readers can communicate with a host via an intermediary device, a concentrator or a controller.

8. Follow the same procedure for connecting other readers to your multidrop network.

Note: For more information, see your reader user’s manual or Microscan’s MS-5000

Multidrop Concentrator User’s Manual, 83-005000.


A-27


Polling Sequence

Data that is transmitted to the host (symbol data, noread messages, counters, etc.) via concentrators is solicited by poll requests from the host.

The polling sequence example is by poll address 1E (ASCII hex value for Reader 02) and a REQ (request). The reader responds by first transmitting its own address, 1E, followed by a STX (start of text) character, and then the data. Next it transmits an

ETX (end of text) character and an LRC (longitudinal redundancy check) character.

If the concentrator (or controller) receives the data from the reader and is able to validate it with an LRC calculation, it responds with an ACK (acknowledgment). If the reader in turn receives the ACK, the reader ends this exchange with a RES (reset).

Start of Sequence End of Sequence

Concentrator

Reader 02

RES 1E REQ

Polling Sequence

Polling Reset

• If the reader has no information, it responds to a poll request by transmitting a RES

(reset).

• If the reader receives a NAK instead of the ACK after transmitting its data string, it will re-attempt to send the data string up to three times. If the reader still does not receive an ACK, it will send a RES (reset) and discard the data in its buffers.

• If the reader transmits data to the concentrator and the concentrator responds with an ACK or NAK, but the reader doesn’t receive the concentrator’s response, the reader will timeout and send a REQ to the concentrator and request another response. If after three retries (the number of times it transmits a REQ to the concentrator) the reader receives no response, it ends the transmission with a RES

(reset).

A-28


Appendices

Select Sequence

Unlike poll requests, select commands always originate from the host and consist of serial configuration or operation commands to devices that are configured in Multidrop.

The reader complies with the command when it is polled during the cycle.

Start of Sequence

End of Sequence

Concentrator RES 1F REQ

Reader 02 1F ACK

STX <T>ETX LRC

1F ACK

RES

Polling Sequence

A RES (reset) is the first command in the select sequence. The 1F hex is the select address associated with Reader 02 address. It is followed by a REQ (request). The reader responds with its own select address, 1F hex, and an ACK (acknowledge). The concentrator then transmits an STX (start of text), the data (in this case a

<T>

), an

ETX (end of text), and an LRC character.

The reader replies by transmitting its own address, followed by an ACK, acknowledging receipt of the command. Upon receipt of an ACK, the concentrator concludes the successful exchange with a RES.

In the example above, the reader only acknowledges a trigger counter request from the concentrator. It does not respond to the trigger counter request until a subsequent poll.

For example, if the reader’s trigger count was 12 at the time the trigger counter request was received, on a subsequent poll it would send 02T/00012. (The 02 at the beginning of the string is the reader’s address.)

Select Reset

If the reader receives bad data from the concentrator, it transmits a SEL (its select address) and a NAK to the concentrator. The concentrator re-transmits the data up to three times. The concentrator will end the sequence with a RES (reset) if no ACK is received.

Terms and Conditions of Sale

1.

Offer; Acceptance. These terms and conditions (these "Terms") are deemed part of all quotes, agreements, purchase orders, acknowledgments, price lists, catalogs, manuals, brochures and other documents, whether electronic or in writing, relating to the sale of products or services (collectively, the "Products") by Omron Electronics LLC and its subsidiary companies (“Omron”). Omron objects to any terms or conditions proposed in Buyer’s purchase order or other documents which are inconsistent with, or in addition to, these Terms.

2.

Prices; Payment Terms. All prices stated are current, subject to change without notice by Omron. Omron reserves the right to increase or decrease prices on any unshipped portions of outstanding orders. Payments for Products are due net 30 days unless otherwise stated in the invoice.

3.

Discounts. Cash discounts, if any, will apply only on the net amount of invoices sent to Buyer after deducting transportation charges, taxes and duties, and will be allowed only if (i) the invoice is paid according to Omron’s payment terms and (ii) Buyer has no past due amounts.

4.

Interest. Omron, at its option, may charge Buyer 1-1/2% interest per month or the maximum legal rate, whichever is less, on any balance not paid within the stated terms.

5.

Orders. Omron will accept no order less than $200 net billing.

6.

Governmental Approvals. Buyer shall be responsible for, and shall bear all costs involved in, obtaining any government approvals required for the importation or sale of the Products.

7.

Taxes. All taxes, duties and other governmental charges (other than general real property and income taxes), including any interest or penalties thereon, imposed directly or indirectly on Omron or required to be collected directly or indirectly by Omron for the manufacture, production, sale, delivery, importation, consumption or use of the Products sold hereunder (including customs duties and sales, excise, use, turnover and license taxes) shall be charged to and remitted by Buyer to Omron.

8.

Financial. If the financial position of Buyer at any time becomes unsatisfactory to Omron, Omron reserves the right to stop shipments or require satisfactory security or payment in advance. If Buyer fails to make payment or otherwise comply with these Terms or any related agreement, Omron may (without liability and in addition to other remedies) cancel any unshipped portion of Products sold hereunder and stop any Products in transit until Buyer pays all amounts, including amounts payable hereunder, whether or not then due, which are owing to it by Buyer. Buyer shall in any event remain liable for all unpaid accounts.

9.

Cancellation; Etc. Orders are not subject to rescheduling or cancellation unless Buyer indemnifies Omron against all related costs or expenses.

10. Force Majeure. Omron shall not be liable for any delay or failure in delivery resulting from causes beyond its control, including earthquakes, fires, floods, strikes or other labor disputes, shortage of labor or materials, accidents to machinery, acts of sabotage, riots, delay in or lack of transportation or the requirements of any government authority.

11. Shipping; Delivery. Unless otherwise expressly agreed in writing by Omron: a. Shipments shall be by a carrier selected by Omron; Omron will not drop ship except in “break down” situations.

b. Such carrier shall act as the agent of Buyer and delivery to such carrier shall constitute delivery to Buyer; c. All sales and shipments of Products shall be FOB shipping point (unless otherwise stated in writing by Omron), at which point title and risk of loss shall pass from Omron to Buyer; provided that Omron shall retain a security interest in the Products until the full purchase price is paid; d. Delivery and shipping dates are estimates only; and e. Omron will package Products as it deems proper for protection against normal handling and extra charges apply to special conditions.

12. Claims. Any claim by Buyer against Omron for shortage or damage to the

Products occurring before delivery to the carrier must be presented in writing to Omron within 30 days of receipt of shipment and include the original transportation bill signed by the carrier noting that the carrier received the Products from Omron in the condition claimed.

13. Warranties. (a) Exclusive Warranty. Omron’s exclusive warranty is that the

Products will be free from defects in materials and workmanship for a period of twelve months from the date of sale by Omron (or such other period expressed in writing by Omron). Omron disclaims all other warranties, express or implied.

(b) Limitations. OMRON MAKES NO WARRANTY OR REPRESENTATION,

EXPRESS OR IMPLIED, ABOUT NON-INFRINGEMENT, MERCHANTABIL-

ITY OR FITNESS FOR A PARTICULAR PURPOSE OF THE PRODUCTS.

BUYER ACKNOWLEDGES THAT IT ALONE HAS DETERMINED THAT THE

PRODUCTS WILL SUITABLY MEET THE REQUIREMENTS OF THEIR

INTENDED USE. Omron further disclaims all warranties and responsibility of any type for claims or expenses based on infringement by the Products or otherwise of any intellectual property right. (c) Buyer Remedy. Omron’s sole obligation hereunder shall be, at Omron’s election, to (i) replace (in the form originally shipped with Buyer responsible for labor charges for removal or replacement thereof) the non-complying Product, (ii) repair the non-complying

Product, or (iii) repay or credit Buyer an amount equal to the purchase price of the non-complying Product; provided that in no event shall Omron be responsible for warranty, repair, indemnity or any other claims or expenses regarding the Products unless Omron’s analysis confirms that the Products were properly handled, stored, installed and maintained and not subject to contamination, abuse, misuse or inappropriate modification. Return of any Products by

Buyer must be approved in writing by Omron before shipment. Omron Companies shall not be liable for the suitability or unsuitability or the results from the use of Products in combination with any electrical or electronic components, circuits, system assemblies or any other materials or substances or environments. Any advice, recommendations or information given orally or in writing, are not to be construed as an amendment or addition to the above warranty.

See http://oeweb.omron.com or contact your Omron representative for published information.

14. Limitation on Liability; Etc. OMRON COMPANIES SHALL NOT BE LIABLE

FOR SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES,

LOSS OF PROFITS OR PRODUCTION OR COMMERCIAL LOSS IN ANY

WAY CONNECTED WITH THE PRODUCTS, WHETHER SUCH CLAIM IS

BASED IN CONTRACT, WARRANTY, NEGLIGENCE OR STRICT LIABILITY.

Further, in no event shall liability of Omron Companies exceed the individual price of the Product on which liability is asserted.

15. Indemnities. Buyer shall indemnify and hold harmless Omron Companies and their employees from and against all liabilities, losses, claims, costs and expenses (including attorney's fees and expenses) related to any claim, investigation, litigation or proceeding (whether or not Omron is a party) which arises or is alleged to arise from Buyer's acts or omissions under these Terms or in any way with respect to the Products. Without limiting the foregoing, Buyer (at its own expense) shall indemnify and hold harmless Omron and defend or settle any action brought against such Companies to the extent based on a claim that any Product made to Buyer specifications infringed intellectual property rights of another party.

16. Property; Confidentiality. Any intellectual property in the Products is the exclusive property of Omron Companies and Buyer shall not attempt to duplicate it in any way without the written permission of Omron. Notwithstanding any charges to Buyer for engineering or tooling, all engineering and tooling shall remain the exclusive property of Omron. All information and materials supplied by Omron to Buyer relating to the Products are confidential and proprietary, and Buyer shall limit distribution thereof to its trusted employees and strictly prevent disclosure to any third party.

17. Export Controls. Buyer shall comply with all applicable laws, regulations and licenses regarding (i) export of products or information; (iii) sale of products to

“forbidden” or other proscribed persons; and (ii) disclosure to non-citizens of regulated technology or information.

18. Miscellaneous. (a) Waiver. No failure or delay by Omron in exercising any right and no course of dealing between Buyer and Omron shall operate as a waiver of rights by Omron. (b) Assignment. Buyer may not assign its rights hereunder without Omron's written consent. (c) Law. These Terms are governed by the law of the jurisdiction of the home office of the Omron company from which

Buyer is purchasing the Products (without regard to conflict of law principles). (d) Amendment. These Terms constitute the entire agreement between

Buyer and Omron relating to the Products, and no provision may be changed or waived unless in writing signed by the parties. (e) Severability. If any provision hereof is rendered ineffective or invalid, such provision shall not invalidate any other provision. (f) Setoff. Buyer shall have no right to set off any amounts against the amount owing in respect of this invoice. (g) Definitions. As used herein, “including” means “including without limitation”; and “Omron Companies” (or similar words) mean Omron Corporation and any direct or indirect subsidiary or affiliate thereof.

Certain Precautions on Specifications and Use

1.

Suitability of Use. Omron Companies shall not be responsible for conformity with any standards, codes or regulations which apply to the combination of the

Product in the Buyer’s application or use of the Product. At Buyer’s request,

Omron will provide applicable third party certification documents identifying ratings and limitations of use which apply to the Product. This information by itself is not sufficient for a complete determination of the suitability of the Product in combination with the end product, machine, system, or other application or use. Buyer shall be solely responsible for determining appropriateness of the particular Product with respect to Buyer’s application, product or system.

Buyer shall take application responsibility in all cases but the following is a non-exhaustive list of applications for which particular attention must be given:

(i) Outdoor use, uses involving potential chemical contamination or electrical interference, or conditions or uses not described in this document.

(ii) Use in consumer products or any use in significant quantities.

(iii) Energy control systems, combustion systems, railroad systems, aviation systems, medical equipment, amusement machines, vehicles, safety equipment, and installations subject to separate industry or government regulations.

(iv) Systems, machines and equipment that could present a risk to life or property. Please know and observe all prohibitions of use applicable to this Product.

NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS

RISK TO LIFE OR PROPERTY OR IN LARGE QUANTITIES WITHOUT

ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TO

ADDRESS THE RISKS, AND THAT THE OMRON’S PRODUCT IS PROP-

ERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE

OVERALL EQUIPMENT OR SYSTEM.

2.

Programmable Products. Omron Companies shall not be responsible for the user’s programming of a programmable Product, or any consequence thereof.

3.

Performance Data. Data presented in Omron Company websites, catalogs and other materials is provided as a guide for the user in determining suitability and does not constitute a warranty. It may represent the result of Omron’s test conditions, and the user must correlate it to actual application requirements. Actual performance is subject to the Omron’s Warranty and Limitations of Liability.

4.

Change in Specifications. Product specifications and accessories may be changed at any time based on improvements and other reasons. It is our practice to change part numbers when published ratings or features are changed, or when significant construction changes are made. However, some specifications of the Product may be changed without any notice. When in doubt, special part numbers may be assigned to fix or establish key specifications for your application. Please consult with your Omron’s representative at any time to confirm actual specifications of purchased Product.

5.

Errors and Omissions. Information presented by Omron Companies has been checked and is believed to be accurate; however, no responsibility is assumed for clerical, typographical or proofreading errors or omissions.
