5. Upon successful decode, the scanner beeps, and the LED turns green. For more
information on beeper and LED definitions, see Table 2-1 and Table 2-2.

Scanning

Aiming
Do not hold the scanner directly over the bar code. Laser light reflecting directly back into
the scanner from the bar code is known as specular reflection. This specular reflection can
make decoding difficult.
The scanner can be tilted up to 65° forward or back and achieve a successful decode (Figure
2-3). Simple practice quickly shows what tolerances to work within.

Scanning in Hands-Free Mode
The optional IntelliStand adds greater flexibility to the scanning operation. When the
scanner is seated in the stand’s “cup,” the scanner’s built-in sensor places the scanner in
hands-free mode. When the scanner is removed from the stand it operates in its normal
hand-held mode.

Figure 2-4. Inserting the Scanner in the IntelliStand
To operate the scanner in the IntelliStand:
1. Ensure the scanner is properly connected to the host (see the appropriate host
chapter for information on host connections).
2. Insert the scanner into the IntelliStand by placing the front of the scanner into the
stand’s “cup” (see Figure 2-4).
3. To scan a bar code, present the bar code and ensure the scan line crosses every bar
and space of the symbol.
4. Upon successful decode, the scanner beeps and the LED turns green. For more
information on beeper and LED definitions, see Table 2-1 and Table 2-2.

User Preferences

Introduction
The scanner can be programed to perform various functions, or activate different features.
This chapter describes each user preference feature and provides the programming bar
codes necessary for selecting these features for the scanner.
The scanner ships with the settings shown in the User Preferences Default Table on page
4-4 (also see Chapter A, Standard Default Parameters for all host device and miscellaneous
scanner defaults). If the default values suit the requirements, programming may not be
necessary.
Feature values are set by scanning single bar codes or short bar code sequences. The
settings are stored in non-volatile memory and are preserved even when the scanner is
powered down.
If the USB cable is not being used, select a host type (see each host chapter for specific host
information). After hearing the power-up beeps, select a host type. This only needs to be
done once, upon the first power-up when connected to a new host.
To return all features to their default values, scan the Set All Defaults bar code on page 45. Throughout the programming bar code menus, default values are indicated with asterisks
(*).

* Indicates Default

*High Frequency

Feature/Option

Scanning Sequence Examples
In most cases, only one bar code needs to be scanned to set a specific parameter value. For
example, to set the beeper tone to high, simply scan the High Frequency (beeper tone) bar
code listed under Beeper Tone on page 4-5. The scanner issues a fast warble beep and the
LED turns green, signifying a successful parameter entry.
Other parameters, such as specifying Laser On Time or setting Data Transmission
Formats, require that several bar codes be scanned. See Laser On Time on page 4-7 and
Scan Data Transmission Format on page 9-7 for descriptions of this procedure.

Errors While Scanning
Unless otherwise specified, if an error is made during a scanning sequence, just re-scan the
correct parameter.

User Preferences Default Parameters
Table 4-1 lists the defaults for user preferences parameters. To change any option, scan the
appropriate bar code(s) provided in the User Preferences section beginning on page 4-5.

Laser On Time
This parameter sets the maximum time that decode processing continues during a scan
attempt. It is programmable in 0.1 second increments from 0.5 to 9.9 seconds. The default
Laser On Time is 3.0 seconds.
To set a Laser On Time, scan the bar code below. Next, scan two numeric bar codes
beginning on page D-1 in Chapter D, Numeric Bar Codes that correspond to the desired on
time. Single digit numbers must have a leading zero. For example, to set a Laser On Time
of 0.5 seconds, scan the bar code below, then scan the “0” and “5” bar codes. In case of an
error, or to change the selection, scan Cancel on page D-7.

Trigger Mode
The scanner has three trigger modes that can be used to scan bar codes. The desired trigger
mode can be set by using the bar codes below.

Level Trigger
When the trigger is pulled, an aiming dot appears for a programmable duration of time.
After this time, the aiming dot automatically turns into a standard laser scanning beam for
a full decode session. The laser scanning beam stays on until the laser-on timeout occurs, a
decode occurs, or the trigger is released. If the trigger is released before the aiming duration
expires, the laser shuts off and no decode occurs.

*Level

User Preferences

Trigger Mode (continued)
Two Stage - Option 1
When the trigger is pulled, an aiming dot appears. This aiming dot remains while the trigger
is pulled. When the trigger is released, the aiming dot automatically turns into a standard
laser scanning beam for a full decode session. The laser scanning beam stays on until the
laser-on timeout occurs or a decode occurs. If the trigger is pulled again while in a decode
session, the scanner beam returns to an aiming dot.

Two Stage - Option 1

Two Stage - Option 2
When the trigger is pulled, an aiming dot appears. When the trigger is released, the aiming
dot turns off. Pulling the trigger twice in rapid succession turns on the standard laser
scanning beam for a full decode session. The laser scanning beam, stays on until the laseron timeout occurs, a decode occurs, or the trigger is released.

Two Stage - Option 2

4-9

4-10

WLS 8400 Product Reference Guide

Aim Duration
When the scanner is in Level trigger mode (default mode), Aim Duration sets the amount
of time the aiming dot is seen before turning into a scanning beam. This parameter has no
affect when the scanner is in either of the Two Stage trigger modes. See Trigger Mode on
page 4-8 for a description of each of the trigger modes.
The aim duration is programmable in 0.1 second increments, from 0.0 to 9.9 seconds. The
default Aim Duration is 0.0 seconds. When set to 0.0 seconds, no aiming pattern appears
before a decode session.
To set an aim duration, scan the bar code below. Then scan two numeric bar codes,
available in Appendix D, Numeric Bar Codes, that correspond to the desired aim duration.
Durations less than 1.0 seconds must have a leading zero. For example, to set an aim
duration of 0.5 seconds, scan the bar code below, followed by the ‘0’ and the ‘5’ bar codes.
In case of an error, or to change the selection, scan the ‘Cancel’ bar code on page D-7.

Keyboard Wedge Interface

Introduction
This chapter provides Keyboard Wedge interface information for setting up the scanner.
This interface type is used to attach the scanner between the keyboard and host computer.
The scanner translates the bar code data into keystrokes. The host computer accepts the
keystrokes as if they originate from the keyboard.
This mode of operation allows adding bar code reading functionality to a system designed
for manual keyboard input. In this mode, the keyboard keystrokes are simply passed
through.
Throughout the programming bar code menus, default values are indicated with asterisks
(*).

To connect the keyboard wedge interface Y-cable:
Interface cables vary depending on configuration. The connectors
illustrated in Figure 5-1 are examples only. The connectors may be
different than those illustrated, but the steps to connect the scanner
remain the same.

1. Turn off the host and unplug the keyboard connector.
2. Attach the modular connector of the Y-cable to the cable interface port on the
scanner. (See Installing the Interface Cable on page 1-5.)
3. Connect the round male DIN host connector of the Y-cable to the keyboard port on
the host.
4. Connect the round female DIN keyboard connector of the Y-cable to the keyboard
connector.
5. If required, attach the optional power supply to the connector in the middle of the
Y-cable.
6. Ensure that all connections are secure.

Ignore Unknown Characters
Unknown characters are characters the host does not recognize. When Send Bar Codes
With Unknown Characters is selected, all bar code data is sent except for unknown
characters, and no error beeps sound on the scanner. When Do Not Send Bar Codes With
Unknown Characters is selected, bar code data is sent up to the first unknown character
and then an error beep sounds on the scanner.

*Send Bar Codes with Unknown Characters

Keystroke Delay
This is the delay in milliseconds between emulated keystrokes. Scan a bar code below to
increase the delay when hosts require a slower transmission of data.

Intra-Keystroke Delay
When enabled, an additional delay is inserted between each emulated key depression and
release. This sets the Keystroke Delay parameter to a minimum of 5 msec, as well.

Caps Lock On
When enabled, the scanner emulates keystrokes as if the Caps Lock key is always pressed.

Enable Caps Lock On

*Disable Caps Lock On

Keyboard Wedge Interface

Caps Lock Override
When enabled, on AT or AT Notebook hosts, the keyboard ignores the state of the Caps
Lock key. Therefore, an ‘A’ in the bar code is sent as an ‘A’ no matter what the state of the
keyboard’s Caps Lock key.

Enable Caps Lock Override

*Disable Caps Lock Override

If both Caps Lock On and Caps Lock Override are enabled, Caps
Lock Override takes precedence.

*Do Not Convert Wedge Data
Function Key Mapping
ASCII values under 32 are normally sent as control key sequences (see Table 5-2 on page
5-19). When this parameter is enabled, the keys in bold are sent in place of the standard key
mapping. Table entries that do not have a bold entry remain the same whether or not this
parameter is enabled.

ASCII Character Set
Code 39 Full ASCII interprets the bar code special character
($ + % /) preceding a Code 39 character and assigns an ASCII
character value to the pair. For example, when Code 39 Full ASCII is
enabled and a +B is scanned, it is interpreted as b, %J as ?, and %V
as @. Scanning ABC%I outputs the keystroke equivalent of ABC >.

Introduction
This chapter provides RS-232 host information for setting up the scanner. The RS-232
interface is used to attach the scanner to point-of-sale devices, host computers, or other
devices with an available RS-232 port (i.e., com port).
If the particular host is not listed in Table 6-2, set the communication parameters to match
the host device. To set communication parameters for hosts not listed, refer to the
documentation for the host device.
This scanner utilizes TTL RS-232 signal levels, which interfaces with
most system architectures. Please contact Wasp Support for more
information.

Throughout the programming bar code menus, default values are indicated with asterisks
(*).

RS-232 Interface

Hardware Handshaking
The data interface consists of an RS-232 port designed to operate either with or without the
hardware handshaking lines, Request to Send (RTS), and Clear to Send (CTS).
If Standard RTS/CTS handshaking is not selected, scan data is transmitted as it becomes
available. If Standard RTS/CTS handshaking is selected, scan data is transmitted according
to the following sequence:
•

•

•
•

The scanner reads the CTS line for activity. If CTS is de-asserted, the scanner waits
up to the Host Serial Response Time-out for the host to de-assert the CTS line. If,
after Host Serial Response Time-out (default), the CTS line is still asserted, the
scanner sounds a transmit error, and any scanned data is lost.
When the CTS line is de-asserted, the scanner asserts the RTS line and waits up to
the Host Serial Response Time-out for the host to assert CTS. When the host asserts
CTS, data is transmitted. If, after Host Serial Response Time-out (default), the CTS
line is still de-asserted, the scanner sounds a transmit error, and discards the data.
When data transmission is complete, the scanner de-asserts RTS 10 msec after
sending the last character.
The host should respond by de-asserting CTS. The scanner checks for a de-asserted
CTS upon the next transmission of data.

During the transmission of data, the CTS line should be asserted. If CTS is de-asserted for
more than 50 ms between characters, the transmission is aborted, the scanner sounds a
transmission error, and the data is discarded.
If the above communications sequence fails, the scanner issues an error indication. In this
case, the data is lost and must be rescanned.
If Hardware Handshaking and Software Handshaking are both enabled, Hardware
Handshaking takes precedence.
The DTR signal is jumped to the active state.

*None
Standard RTS/CTS
Scan the bar code below to select Standard RTS/CTS Hardware Handshaking.

Standard RTS/CTS

RTS/CTS Option 1
When RTS/CTS Option 1 is selected, the scanner asserts RTS before transmitting and
ignores the state of CTS. The scanner de-asserts RTS when the transmission is complete.

RTS/CTS Option 1

RS-232 Interface

Hardware Handshaking (continued)
RTS/CTS Option 2
When Option 2 is selected, RTS is always high or low (user-programmed logic level).
However, the scanner waits for CTS to be asserted before transmitting data. If CTS is not
asserted within Host Serial Response Time-out (default), the scanner issues an error
indication and discards the data.

RTS/CTS Option 2

RTS/CTS Option 3
When Option 3 is selected, the scanner asserts RTS prior to any data transmission,
regardless of the state of CTS. The scanner waits up to Host Serial Response Time-out
(default) for CTS to be asserted. If CTS is not asserted during this time, the scanner issues
an error indication and discards the data. The scanner de-asserts RTS when transmission is
complete.

RTS/CTS Option 3

Software Handshaking
This parameter offers control of the data transmission process in addition to, or instead of,
that offered by hardware handshaking. There are five options.
If Software Handshaking and Hardware Handshaking are both enabled, Hardware
Handshaking takes precedence.

None
When this option is selected, data is transmitted immediately. No response is expected from
host.

*None
ACK/NAK
When this option is selected, after transmitting data, the scanner expects either an ACK or
NAK response from the host. When a NAK is received, the scanner transmits the same data
again and waits for either an ACK or NAK. After three unsuccessful attempts to send data
when NAKs are received, the scanner issues an error indication and discards the data.
The scanner waits up to the programmable Host Serial Response Time-out to receive an
ACK or NAK. If the scanner does not get a response in this time, it issues an error indication
and discards the data. There are no retries when a time-out occurs.

ACK/NAK

RS-232 Interface

Software Handshaking (continued)
ENQ
When this option is selected, the scanner waits for an ENQ character from the host before
transmitting data. If an ENQ is not received within the Host Serial Response Time-out, the
scanner issues an error indication and discards the data. The host must transmit an ENQ
character at least every Host Serial Response Time-out to prevent transmission errors.

ENQ

ACK/NAK with ENQ
This combines the two previous options. For re-transmissions of data, due to a NAK from
the host, an additional ENQ is not required.

ACK/NAK with ENQ

XON/XOFF
An XOFF character turns the scanner transmission off until the scanner receives an XON
character. There are two situations for XON/XOFF:
•

•

XOFF is received before the scanner has data to send. When the scanner has data
to send, it waits up to Host Serial Response Time-out for an XON character before
transmission. If the XON is not received within this time, the scanner issues an
error indication and discards the data.
XOFF is received during a transmission. Data transmission then stops after sending
the current byte. When the scanner receives an XON character, it sends the rest of
the data message. The scanner waits up to 30 seconds for the XON.

To set up the scanner:
Interface cables vary depending on configuration. The connectors
illustrated in Figure 7-1 are examples only. The connectors may be
different than those illustrated, but the steps to connect the scanner
remain the same.

1. Attach the modular connector of the USB interface cable to the cable interface port
on the scanner. (See Installing the Interface Cable on page 1-5.)
2. Plug the series A connector in the USB host or hub, or plug the Plus Power
connector in an available port of the IBM SurePOS terminal.
3. Ensure that all connections are secure.
4. Select the USB device type by scanning the appropriate bar code from the USB
Device Type section on page 7-7.
5. On first installation when using Windows, the software displays a prompt to select
or install the "Human Interface Device" driver. To install the "Human Interface
Device" driver provided by Windows click "Next" through all the choices and click
"Finished" on the last choice. The scanner powers up during this installation.
6. To modify any other parameter options, scan the appropriate bar codes in this
chapter.
If there are any problems with the system, see Troubleshooting on page 3-4.

Introduction
This chapter describes all symbology features and provides the programming bar codes
necessary for selecting these features for the scanner. Before programming, follow the
instructions in Chapter 1, Getting Started.
The scanner is shipped with the settings shown in the Symbology Default Table on page 86 (also see Chapter A, Standard Default Parameters for all host device and miscellaneous
scanner defaults). If the default values suit the requirements, programming may not be
necessary. Features values are set by scanning single bar codes or short bar code sequences.
To return all features to their default values, scan the Set All Defaults bar code on page 4-5.
If the USB cable is not being used, a host type must be selected. See each host chapter for
specific host information.

Scanning Sequence Examples
In most cases, only one bar code needs to be scanned to set a specific parameter value. For
example, to transmit bar code data without the UPC-A check digit, scan the Do Not Transmit
UPC-A Check Digit bar code listed under Transmit UPC-A/UPC-E/UPC-E1 Check Digit on
page 8-15. The scanner issues a fast warble beep and the LED turns green, signifying a
successful parameter entry.
Other parameters, such as Set Length(s) for D 2 of 5 require that several bar codes be
scanned in the proper sequence. See the individual parameter, like Set Length(s) for D 2
of 5, for this procedure.

Errors While Scanning
Unless otherwise specified, if an error is made during a scanning sequence, just re-scan the
correct parameter.

•

•

If Decode UPC/EAN Only With Supplementals is selected, UPC/EAN symbols
without supplementals are not decoded.
If Ignore Supplementals is selected, and the scanner is presented with a
UPC/EAN with a supplemental, the UPC/EAN is decoded and the supplemental
bar code is ignored.
An Autodiscriminate Option is also available. If this option is selected, choose an
appropriate UPC/EAN/JAN Supplemental Redundancy value from the next page.
A value of 14 or more is recommended.
Enable 378/379 Supplemental Mode to enable only EAN13 bar codes starting
with a ‘378’ or ‘379’ prefix to be delayed by the supplemental search process. All
other UPC/EAN bar codes are exempted from the search and are reported instantly
upon their decode.
Select Enable 978 Supplemental Mode to enable only EAN13 bar codes starting
with a ‘978’ prefix to be delayed by the supplemental search process. All other
UPC/EAN bar codes are exempted from the search and are reported instantly upon
their decode.
Select Enable Smart Supplemental Mode to enable only EAN13 bar codes
starting with a ‘378’, ‘379’, or ‘978’ prefix to be delayed by the supplemental
search process. All other UPC/EAN bar codes are exempted from the search and
are reported instantly upon their decode.
In order to minimize the risk of invalid data transmission, it is
recommended to select either to decode or ignore supplemental
characters.

UPC/EAN/JAN Supplemental Redundancy
With Autodiscriminate UPC/EAN/JAN Supplementals selected, this option adjusts the
number of times a symbol without supplementals is decoded before transmission. The
range is from two to thirty times. 14 or above is recommended when decoding a mix of
UPC/EAN symbols with and without supplementals, and the autodiscriminate option is
selected. The default is set at 14.
Scan the bar code below to set a decode redundancy value. Next, scan two numeric bar
codes beginning on page D-3 in Chapter D, Numeric Bar Codes. Single digit numbers must
have a leading zero. In case of an error, or to change the selection, scan Cancel on page D-7.

Set Lengths for Code 39
The length of a code refers to the number of characters (i.e., human readable characters),
including check digit(s) the code contains. Lengths for Code 39 may be set for any length,
one or two discrete lengths, or lengths within a specific range. If Code 39 Full ASCII is
enabled, Length Within a Range or Any Length are the preferred options.
When setting lengths for different bar code types by scanning single
digit numbers, single digit numbers must always be preceded by a
leading zero.

One Discrete Length - This option allows the scanner to decode only those Code 39
symbols containing a selected length. Lengths are selected from the numeric bar codes
beginning on page D-1 in Chapter D, Numeric Bar Codes. For example, to decode only
Code 39 symbols with 14 characters, scan Code 39 - One Discrete Length, then scan 1
followed by 4. In case of an error, or to change the selection, scan Cancel on page D-7.

Security Level
The scanner offers four levels of decode security for UPC/EAN bar codes. Increasing levels
of security are provided for decreasing levels of bar code quality. There is an inverse
relationship between security and scanner decode speed, so be sure to choose only that level
of security necessary for any given application.

Security Level 0
This is the default setting which allows the scanner to operate fastest, while providing
sufficient security in decoding “in-spec” UPC/EAN bar codes.

*Security Level 0
Security Level 1
As bar code quality levels diminish, certain characters become prone to misdecodes before
others (i.e., 1, 2, 7, 8). If the scanner is misdecoding poorly printed bar codes, and the
misdecodes are limited to these characters, select this security level.

Security Level 3
If Security Level 2 has been tried, and the scanner is still misdecoding, select this security
level. Be advised, selecting this option is an extreme measure against misdecoding severely
out of spec bar codes. Selection of this level of security may significantly impair the
decoding ability of the scanner. If this level of security is necessary, try to improve the

Introduction
This chapter includes commonly used bar codes to customize how the data is transmitted
to the host device. In addition to these bar codes for data formatting, see each host chapter
for the appropriate host connections and host device features for the scanner. See Chapter
8, Symbologies and Chapter 10, Advanced Data Formatting for customizing data for
transmission to the host device.
Before programming, follow the instructions in Chapter 1, Getting Started.
The scanner is shipped with the settings shown in the Miscellaneous Scanner Options
Default Table on page 9-4 (also see Chapter A, Standard Default Parameters for all host
device and miscellaneous scanner defaults). If the default values suit the requirements,
programming may not be necessary. Features values are set by scanning single bar codes
or short bar code sequences.

Scanning Sequence Examples
In most cases, only one bar code needs to be scanned to set a specific parameter value.
Parameters, such as Prefix Value, require that several bar codes be scanned in the proper
sequence. See each individual parameter for descriptions of this procedure.

Errors While Scanning
Unless otherwise specified, if an error is made during a scanning sequence, re-scan the
correct parameter.

Miscellaneous Default Parameters
Table 9-1 lists the defaults for miscellaneous scanner options parameters. To change any
option, scan the appropriate bar code(s) provided in the Miscellaneous Scanner Parameters
section beginning on page 9-5.
See Chapter A, Standard Default Parameters for all user preferences,
hosts, symbologies, and miscellaneous default parameters.

Advanced Data Formatting

Introduction
Advanced Data Formatting (ADF) is a means of customizing data before transmission to
the host device. Scan data can be edited to suit the particular requirements.
ADF can be implemented through scanning a related series of bar codes, which begin on
page 10-9 which allows the scanner to be setup and programmed with Advanced Data
Formatting (ADF) Rules.

Rules: Criteria Linked to Actions
In ADF, data is customized through rules. These rules perform detailed actions when the
data meets certain criteria. One rule may consist of single or multiple criteria applied to
single or multiple actions.
For instance, a data formatting rule could be the following:
Criteria:When scan data is Code 39, length 12, and data at the start position is
the string “129”,
Actions:pad all sends with zeros to length 8,
send all data up to X,
send a space.
If a Code 39 bar code of 1299X1559828 is scanned, the following is transmitted:
00001299. If a Code 39 bar code of 1299X15598 is scanned, this rule is ignored
because the length criteria has not been met.
The rule specifies the editing conditions and requirements before data transmission occurs.

Using ADF Bar Codes
When a rule is programed, make sure the rule is logically correct. Plan ahead before starting
to scan.
To program each data formatting rule:
•
•

•

Start the Rule. Scan the Begin New Rule bar code on page 10-9.
Criteria. Scan the bar codes for all pertinent criteria. Criteria can include code type
(e.g., Code 128), code length, or data that contains a specific character string (e.g.,
the digits “129”). These options are described in Criteria on page 10-12.
Actions. Scan all actions related to, or affecting, these criteria. The actions of a rule
specify how to format the data for transmission. These options are described in
ADF Bar Code Menu Example on page 10-4.

10-3

10-4

WLS 8400 Product Reference Guide

•

Save the Rule. Scan the Save Rule bar code on page 10-9. This places the rule in
the “top” position in the rule buffer.
• In case of errors made during this process, some special-purpose bar codes may be
useful: Erase Criteria and Start Again, Erase Actions and Start Again, Erase
Previously Saved Rule, etc.
Criteria, actions, and entire rules may be erased by scanning the appropriate bar code (see
page 10-10).
Use the Beeper Definitions on page 2-4 as a guide for the programming steps.

ADF Bar Code Menu Example
This section provides an example of how ADF rules are entered and used for scan data.
An auto parts distribution center wants to encode manufacturer ID, part number, and
destination code into their own Code 128 bar codes. The distribution center also has
products that carry UPC bar codes, placed there by the manufacturer. The Code 128 bar
codes have the following format:
MMMMMPPPPPDD
Where:
M = Manufacturer ID
P = Part Number
D = Destination Code
The distribution center uses a PC with dedicated control characters for manufacturer ID
, part number , and destination code . At this center the
UPC data is treated as manufacturer ID code.
The following rules need to be entered:
When scanning data of code type Code 128, send the next 5 characters, send the
manufacturer ID key , send the next 5 characters, send the part number key
, send the next 2 characters, send the destination code key .
When scanning data of code type UPC/EAN, send all data, send the manufacturer ID
key .
To enter these rules, follow the steps below:

In case of errors while entering this rule, scan the Quit Entering Rules bar code on page
10-10. If the rule is already saved, scan the Erase Previously Saved Rule bar code on page
10-10.

Alternate Rule Sets
ADF rules may be grouped into one of four alternate sets which can be turned on and off
when needed. This is useful to format the same message in different ways. For example, a
Code 128 bar code contains the following information:
Class (2 digits), Stock Number (8) digits, Price (5 digits)
This bar code might look like this:
245671243701500

10-5

10-6

WLS 8400 Product Reference Guide

where:
Class = 24
Stock Number = 56712437
Price = 01500
Ordinarily, data is sent as follows:
24 (class key)
56712437 (stock key)
01500 (enter key)
But, when there is a sale, send only the following:
24 (class key)
56712437 (stock key)
and the cashier keys the price manually.
To implement this, first enter an ADF rule that applies to the normal situation. This rule
may look like this:
When scanning a bar code of length 15, send the next 2 characters, send the class key,
send the next 8 characters, send the stock key, send the data that remains, send the Enter
key.
The “sale” rule may look like this:
When scanning a bar code of length 15, send the next 2 characters, send the class key,
send the next 8 characters, send the stock key.
To switch between the two sets of rules, a “switching rule” must be programmed. This rule
specifies what type of bar code must be scanned to switch between the rule sets. For
example, in the case of the “sale” rule above, the rule programmer wants the cashier to scan
the bar code “M” before a sale. To do this, a rule can be entered as follows:
When scanning a bar code of length 1 that begins with “M”, select rule set number 1.
Another rule could be programmed to switch back.
When scanning a bar code of length 1 that begins with “N”, turn off rule set number 1.

Advanced Data Formatting

The switching back to normal rules can also be done in the “sale” rule. For example, the
rule may look like this:
When scanning a bar code of length 15, send the next 2 characters, send the class key,
send the next 8 characters, send the stock key, turn off rule set 1.
It is recommended that the Disable All Rule Sets bar code on page 10-11 be scanned after
programming a rule belonging to an alternate rule set.
In addition to enabling and disabling rule sets within the rules, it is possible to enable or
disable them by scanning the appropriate bar codes on 10-11.

Rules Hierarchy (in Bar Codes)
The order of programming individual rules is important.The most general rule should be
programmed last.
All programmed rules are stored in a buffer. As they are programmed, they are stored at the
“top” of a rules list. If three rules have been created, the list would be configured as follows:
Third Rule
Second Rule
First Rule
When data is scanned, the rules list is checked from top to bottom to determine if the criteria
matches (and therefore, if the actions should occur). Input is modified into the data format
specified by the first matching set of criteria it finds. Be sure that the most general rule is
the last one programmed.
For example, if the THIRD rule states:
When scanning a bar code of any length, send all data, then send the ENTER key.
And the SECOND rule states:
When scanning a Code 128 bar code of length 12, send the first four characters, then
send the ENTER key, then send all remaining data.
If a Code 128 bar code of length 12 were scanned, the THIRD rule would be in effect. The
SECOND rule would appear to not function.
Note also that ADF rules are actually created when the standard data editing functions are
used. Scan options are entered as ADF rules, and the hierarchy mentioned above also
applies to them. For the scanner, this applies to prefix/suffix programming in the parameter
Scan Data Transmission Format.

10-7

10-8

WLS 8400 Product Reference Guide

These rules reside in the same “rule list” as ADF Rules, so the order of their creation is also
important.

Default Rules
Every unit has a default rule to send all scan data. Units with custom software may have
one or more default rules burned in. The rules hierarchy checks user programmable rules
first, then the default rules. Default rules can be disabled by entering the following general
rule in the user programmable buffer:
When receiving scan data, send all data.
Since this rule always applies, ADF never goes into the default rules.

Advanced Data Formatting

Special Commands
Pause Duration
This parameter along with the Send Pause parameter on page 10-33 allows a pause to be
inserted in the data transmission. Pauses are set by scanning a two-digit number (i.e., two
bar codes), and are measured in 0.1 second intervals. For example, scanning bar codes “0”
and “1” inserts a 0.1 second pause; “0” and “5” gives a 0.5 second delay. Numeric bar
codes begin on page D-1 in Chapter D, Numeric Bar Codes. In case of an error, or to
change the selection, scan Numeric Cancel on page D-6.

Move Cursor
Move Cursor To a Character

Scan the Move Cursor To Character bar code on page
10-33, then any printable ASCII character from the

cursor moves to the position after the matching
character. If the character is not there, the rule fails
and ADF tries the next rule.
Move Cursor to Start of Data

Scan this bar code to move cursor to the beginning of the
data.

10-33

Move Cursor Past a Character

This parameter moves the cursor past all sequential
10-33
occurrences of a selected character. For example, if the
selected character is ‘A’, then the cursor moves past ‘A’,
‘AA’, ‘AAA’, etc. Scan the Move Cursor Past Character
bar code on page 10-33, then select a character from the
Alphanumeric Keyboard. If the character is not there, the
cursor does not move (i.e., has no effect).

Skip Ahead “N” Characters

Scan one of these bar codes to select the desired number of 10-34
positions to move the cursor ahead.

Skip Back “N” Characters

Scan one of these bar codes to select the desired number of 10-36

numerals, punctuation marks, and control characters.
It is a standard data transmission code in the U.S.

Aspect Ratio

The ratio of symbol height to symbol length in a 2dimensional symbol.

Autodiscrimination

The ability of an interface controller to determine the
code type of a scanned bar code. After this
determination is made, the information content is
decoded.

Automatic Identification System

The application of various technologies, such as bar
code recognition, image recognition, voice
recognition and RF/MW transponders, for the
purpose of data entry into a data processing system
and bypassing the key-entry component of traditional
data entry.

Background

The area surrounding a printed symbol including the
spaces and quiet zones.

Bar

The dark element in a printed bar code symbol.

Bar Code

An array of parallel rectangular bars and spaces
arranged according to the encodation rules of a
particular symbol specification in order to represent
data in machine-readable form (i.e., Code 39).

Bar Code Character

A single group of bars and spaces which represent an
individual number, letter, punctuation mark or other
symbol.

Bar Code Density

The number of characters represented per unit of
measurement (e.g., characters per inch).

Bar Code Reader

A device used to read or decode a bar code symbol.

Bar Code Symbol

The combination of symbol characters and features
required by a particular symbology, including quiet
zones, start and stop characters, data characters,
check characters and other auxiliary patterns, that
together form a complete scannable entity (see
Symbol).

Bar Height

The dimension of a bar measured perpendicular to the
bar width (see Y Dimension).

Glossary

Bar Width

Thickness of a bar measured from the edge closest to
the symbol start character to the trailing edge of the
same bar (see X Dimension).

Baud Rate

A measure of the data flow or number of signaling
events occurring per second. When one bit is the
standard "event," this is a measure of bits per second
(bps). For example, a baud rate of 50 means
transmission of 50 bits of data per second.

Bi-directional

Denotes that a machine-readable symbol can be read
successfully in two directions – either backwards or
forwards. Also identifies a scanner that can operate or
a bar code that can be read independent of scanning
direction.

Binary

Denotes a numbering system to base 2 in which
numbers are expressed as combinations of the digits
0 and 1 with positional weighting based on powers of
2. In computing, these can be represented electrically
by 'off' and 'on' respectively or in machine-readable
symbols by narrow and wide elements or by the
absence or presence of a bar module.

Bit

Binary digit. One bit is the basic unit of binary
information. Generally, eight consecutive bits
compose one byte of data. The pattern of 0 and 1
values within the byte determines its meaning.

Byte

A sequential series of bits comprising one character
and handled as one unit. Usually encoded in the
ASCII format, a byte usually consists of eight bits and
represents one alphabetic or special character, two
decimal digits or eight binary bits.

CDRH

Center for Devices and Radiological Health. A
federal agency responsible for regulating laser
product safety. This agency specifies various laser
operation classes based on power output during
operation.

This is the lowest power CDRH laser classification.
This class is considered intrinsically safe, even if all
laser output were directed into the eye's pupil. There
are no special operating procedures for this class.

GL-3

GL-4

WLS 8400 Product Reference Guide

CDRH Class 2

A pattern of bars and spaces which either directly
represents data or indicates a control function, such as
a number, letter, punctuation mark, or
communications control contained in a message.

Character Set

Those characters available for encoding in a
particular bar code symbology.

Check Digit

A digit used to verify a correct symbol decode. The
scanner inserts the decoded data into an arithmetic
formula and checks that the resulting number
matches the encoded check digit. Check digits are
required for UPC but are optional for other
symbologies. Using check digits decreases the
chance of substitution errors when a symbol is
decoded.

Codabar

A discrete self-checking code with a character set
consisting of digits 0 to 9 and six additional
characters: ( - $ : / , +).

Code

A set of unambiguous rules specifying the way in
which data may be represented as numbers and letters

controller to encode all 128 ASCII characters without
adding extra symbol elements.

Code 3 of 9 (Code 39)

A versatile and widely used alphanumeric bar code
symbology with a set of 43 character types, including
all uppercase letters, numerals from 0 to 9, and 7
special characters (- . / + % $ and space). The code
name is derived from the fact that 3 of 9 elements
representing a character are wide, while the
remaining 6 are narrow.

Code 49

This symbol is a stack of 2 to 8 rows. Each row
encodes row count information plus data characters.
For more information, go to the AIM web site or the
ANSI web site (see Stacked Symbol (2D Symbols)).

Glossary

strings by appending each string in succession. The
linking or chaining together of separate items of data
in a bar code symbol or of the data contained in two
or more separate bar code symbols (also referred to as
message append and structured append).

Continuous Code

A bar code or symbol in which all spaces within the
symbol are parts of characters. There are no
intercharacter gaps in a continuous code. The absence
of gaps allows for greater information density.

Contrast

The difference in reflectance between the black and
white (or bar and space) areas of a symbol.

Data Identifier

A specified character or string of characters that
defines the intended use of the data element that
follows. For the purposes of automatic data capture

Data Matrix

This error correcting, 2-dimensional matrix
symbology is capable of encoding various character
sets including strictly numeric data, alphanumeric
data and all ISO 646 (ASCII) characters, as well as
special character sets. The symbology has both error
detection and error correction features. Each Data
Matrix symbol consists of data regions, which
contain nominally square modules set out in a regular
array. A dark module is a binary 1 and a light module
is a binary 0. There is no specified minimum or
maximum for the X or Y dimension. The data region
is surrounded by a finder pattern, a perimeter to the
data region that is 1 module wide, which is
surrounded by a quiet zone on all four sides of the
symbol. Two adjacent sides are solid dark lines used
primarily to define physical size, orientation and
symbol distortion. The two opposite sides consist of
alternating dark and light modules. These are used
primarily to define the cell structure but also assist in
determining physical size and distortion.
There are 2 types of Data Matrix symbologies: ECC
000 - 140 with several available levels of
convolutional error correction, and ECC 200, which
uses Reed-Solomon error correction. For ISO/IEC
JTC 1/SC 31 purposes, only ECC 200 is
recommended. The intellectual property rights
associated with Data Matrix have been committed to
the public domain.

Data Structure

The stipulation of the type of information that is
included in a bar code, such as its order and format.

Dead Zone

An area within a scanner's field of view, in which
specular reflection may prevent a successful decode.

Decode

To recognize a bar code symbology (e.g., UPC/EAN)
and then analyze the content of the specific bar code
scanned.

Decode Algorithm

A decoding scheme that converts pulse widths into
data representation of the letters or numbers encoded
within a bar code symbol.

Glossary

Decoder

An electronic package that receives the signals from
the scanning function, performs the algorithm to
interpret the signals into meaningful data and
provides the interface to other devices.

Density

Describes the relative amount of memory contained
in a radio frequency identification tag (see Bar Code
Density).

Depth of Field

The range between minimum and maximum
distances at which a scanner can read a symbol with
a certain minimum element width.

Diffuse Reflection

The component of reflected light that emanates in all
directions from the reflecting surface.

Discrete 2 of 5

A binary bar code symbology representing each
character by a group of five bars, two of which are
wide. The location of wide bars in the group
determines which character is encoded; spaces are
insignificant. Only numeric characters (0 to 9) and
START/STOP characters may be encoded.

Discrete Code

A bar code or symbol in which the spaces between
characters (intercharacter gaps) are not part of the
code.

EAN

European Article Number. This European/
international version of the UPC provides its own
coding format and symbology standards. Element
dimensions are specified metrically. EAN is used
primarily in retail.

EAN/U.P.C.

A fixed-length, numeric 13-digit bar code symbol
consisting of 30 dark elements and 29 intervening
light elements. Each character is represented by 2
bars and 2 spaces over 7 modules. A bar may be
comprised of 1, 2, 3 or 4 modules. Each EAN/U.P.C.
symbol consists of a leading quiet zone, a start
pattern, 7 left-hand data characters, a center bar
pattern, 5 right-hand data characters, a Modulo 10
check character, a stop pattern and a trailing quiet
zone. U.P.C. is often considered a 12-digit code. The
13th digit of EAN/U.P.C. symbol is a derived
character in the left-most position. In the case of
U.P.C., this derived left-most character is a 0.

Element

Generic term for a bar or space.

GL-7

GL-8

WLS 8400 Product Reference Guide

Encoded Area

Total linear dimension occupied by all characters of a
code pattern, including start/stop characters and data.

Error Correction

A reader or decoder's use of mathematical schemes to
reconstruct or replace damaged or missing symbol
characters to enable the reading of the symbol data.

Error Detection

This occurs when error-correction characters detect
that the presence of errors in the symbol exceeds the
error correction capacity, and keeps the symbol from
being decoded as erroneous data.

Error-Correction Characters

Symbol characters used for error correction and
detection, calculated automatically from the other
symbol characters.

Error-Correction Level

An indicator of the number of characters used in a
symbology for error correction. A higher level of
error correction allows for correcting greater
potential symbol damage.

Error-Detection Characters

Symbol characters reserved for error detection that
are calculated automatically from the other symbol
characters.

Fixed Beam Bar Code Reader

A scanning device where scanning motion is
achieved by moving the object relative to the reader;
as opposed to a moving beam reader.

Guard Bars

Bars located at both ends and the center of a UPC and
EAN symbol to provide reference points for
scanning.

Glossary

IEC (825) Class 1

This is the lowest power IEC laser classification.
Conformity is ensured through a software restriction
of 120 seconds of laser operation within any 1000
second window and an automatic laser shutdown if
the scanner's oscillating mirror fails.

Intercharacter Gap

The space between two adjacent bar code characters
in a discrete code.

Interleaved 2 of 5

A binary bar code symbology representing character
pairs in groups of five bars and five interleaved
spaces. Interleaving provides for greater information
density. The location of wide elements (bar/spaces)
within each group determines which characters are
encoded. This continuous code type uses no
intercharacter spaces. Only numeric (0 to 9) and
START/STOP characters may be encoded.

Interleaved Bar Code

A bar code in which characters are paired together,
using bars to represent the first character and the
intervening spaces to represent the second.

The laser is an intense light source. Light from a laser
is all the same frequency, unlike the output of an
incandescent bulb. Laser light is typically coherent
and has a high energy density.

Laser Diode

A gallium-arsenide semiconductor type of laser
connected to a power source to generate a laser beam.
This laser type is a compact source of coherent light.

Laser Scanner

An optical bar code reading device using a coherent
laser light beam as its source of illumination.

LED Indicator

Diode) used as an indicator, often in digital displays.
The semiconductor uses applied voltage to produce
light of a certain frequency determined by the
semiconductor's particular chemical composition.

Matrix Symbols

A 2-dimensional array of regular polygon shaped
cells where the center-to-center distance of adjacent
elements is uniform. The arrangement of the cells
represents data and/or symbology functions. Matrix
symbols may include recognition patterns that do not
follow the same rule as the other elements within the
symbol (i.e., Data Matrix and MaxiCode).

Misread (Misdecode)

A condition which occurs when the data output of a
reader or interface controller does not agree with the
data encoded within a bar code symbol.

Module

(1) The narrowest nominal width unit of measure in a
symbol. In certain symbologies, element widths are
specified as multiples of 1 module. Equivalent to X
dimension; or (2) a single cell in a matrix symbology
used to encode 1 bit of data. In MaxiCode, the module
shape is a regular hexagon. In Data Matrix, the
module shape is nominally square. In PDF417, the
module shape is a regular rectangle. In bar code
symbologies, the module shape is a regular rectangle.

Standard size for a bar code symbol. Most UPC/EAN
codes are used over a range of magnifications (e.g.,
from 0.80 to 2.00 of nominal).

Non-Contact Reader/Scanner

Bar code readers requiring no physical contact with
the printed symbol.

Non-read

The absence of data at the scanner output after an
attempted scan, which is due to no code, defective
code, scanner failure or operator error.

Glossary

Omnidirectional

Bar codes read in any orientation relative to the
scanner.

Optical Throw

The distance from the scanner face to the closest
point at which symbol can be read; also, optical throw
is the difference between range and depth of field.

Orientation

The alignment of the symbol's scan path. Two
possible orientations are horizontal with vertical bars
and spaces (picket fence) and vertical with horizontal
bars and spaces (ladder).

Overhead

The fixed number of characters required for start,
stop and checking in a given symbol. For example, a
symbol requiring a start, stop and 2 check characters
contains 4 characters of overhead.

Parameter

A variable that can have different values assigned to
it.

PDF417

An error correcting 2-dimensional multi-row symbol
developed in 1992 by Symbol Technologies, PDF417
symbols are constructed from 4 bars and 4 spaces
over 17 modules. The symbol size is from 3 to 90
rows. There is no specified minimum or maximum
for X or Y dimension. With at least the recommended
minimum level of error correction, the recommended
Y dimension is 3X. With less than the minimum
recommended level of error correction, the
recommended Y dimension is 4X. A quiet zone of 2X
is specified on each side of a symbol. Because of
delta decode techniques, the symbology is immune
from uniform bar width growth. PDF417 supports
cross-row scanning. The intellectual property rights
associated with PDF417 have been committed to the
public domain.

Percent Decode

The average probability that a single scan of a bar
code would result in a successful decode. In a welldesigned bar code scanning system, that probability
should approach near 100%.

Pitch

Rotation of a bar code symbol in an axis parallel to
the direction of the bars.

Plessey Code

A pulse-width, modulated bar code commonly used
for shelf marking in grocery stores.

GL-11

Postnet Code

Code developed by the U.S. Postal Service to assist in
the automatic sorting of mail.

Print Contrast Signal (PCS)

Measurement of the contrast (brightness difference)
between the bars and spaces of a symbol. A minimum
PCS value is needed for a bar code symbol to be
scannable.
PCS = (RL - RD) / RL, where RL is the reflectance
factor of the background and RD the reflectance
factor of the dark bars.

Programming Mode

The state in which a scanner is configured for
parameter values (see Scanning Mode).

Quiet Zone

A clear space, containing no dark marks, which
precedes the start character of a bar code symbol and
follows the stop character.

Radio Frequency

Non-optical automatic identification devices that use
radio waves to transmit data.

Radio Frequency Data Communication
(RFDC)

Handheld or vehicle mounted units that send and
receive messages by radio frequency. Information
from the units is displayed on a screen for workers
and allows real-time, two-way exchange of data
between terminals when one terminal is mobile and
the other is a host computer at a remote location.

Radio Frequency Identification (RFID)

The use of small radio transponders that are activated
by a reading transmitter. The transponder carries a
unique ID code or other information in its memory
and can be read at a distance without line of sight.

Radio Frequency Tag

An electronic tag capable of receiving, storing and/or
transmitting digital information.

Reflectance

Amount of light returned from an illuminated surface.

Resolution

The narrowest element dimension which is
distinguished by a particular reading device or
printed with a particular device or method.

RSS

Reduced Space Symbology: A family of space
efficient symbologies developed by UCC.EAN.

Scan Area

Area intended to contain a symbol.

Glossary

Scanner

An electronic device used to scan bar code symbols
and produce a digitized pattern that corresponds to
the bars and spaces of the symbol. Its three main
components are:
1. Light source (laser or photoelectric cell) illuminates a bar code.
2. Photodetector - registers the difference in reflected
light (more light reflected from spaces).
3. Signal conditioning circuit - transforms optical
detector output into a digitized bar pattern.

Scanning Mode

The scanner is energized, programmed, and ready to
read a bar code.

Scanning Sequence

A method of programming or configuring parameters
for a bar code reading system by scanning bar code
menus.

Self-Checking Code

A symbology that uses a checking algorithm to detect
encoding errors within the characters of a bar code
symbol.

Skew

Rotation of a bar code symbol on an axis parallel to
the symbol's length.

Space

The lighter element of a bar code formed by the
background between bars.

Space Width

The thickness of a space measured from the edge
closest to the symbol start character to the trailing
edge of the same space.

Specular Reflection

The mirror-like direct reflection of light from a
surface, which can cause difficulty decoding a bar
code.

Stacked Symbol (2D Symbols)

A 2-dimensional (2D) symbol with sequences of
linear (width-coded) data that are stacked one upon
another (i.e., PDF417).

Start/Stop Character

A pattern of bars and spaces that provides the scanner
with start and stop reading instructions and scanning
direction. The start and stop characters are normally
to the left and right margins of a horizontal code.

Substrate

A foundation material on which a substance or image
is placed.

GL-13

Symbol

A scannable unit that encodes data within the
conventions of a certain symbology, usually
including start/stop characters, quiet zones, data
characters, and check characters.

Symbol Aspect Ratio

The ratio of symbol height to symbol width.

Symbol Density

The number of data characters per unit length; usually
expressed as characters per inch (CPI).

Symbol Height

The distance between the outside edges of the quiet
zones of the first row and the last row.

Symbol Length

Length of symbol measured from the beginning of
the quiet zone (margin) adjacent to the start character
to the end of the quiet zone (margin) adjacent to a stop
character.

Symbology

The structural rules and conventions for representing
data within a particular bar code type (e.g. UPC/
EAN, Code 39).

Tilt

Rotation of a bar code symbol on an axis
perpendicular to the substrate.

Tolerance

Allowable deviation from the nominal bar or space
width.

2-dimensional (2D) symbology

A machine-readable symbol which must be examined
both vertically and horizontally to read the entire
message. A 2D symbol may be one of two types of
machine-readable symbols: a Matrix Symbol or a
stacked symbol. 2D symbols differ from linear bar
codes with the ability for high data content, small
size, data efficiency and error correction capability.

UCC

Uniform Code Council: the organization that
administers the U.P.C and other retail standards.

UCC.EAN-128

Code 128 with a Function 1 character in the first
position that is the symbology used with the
UCC.EAN format for a universal product number
(UPN).

UPC

Universal Product Code. A relatively complex
numeric symbology. Each character consists of two
bars and two spaces, each of which is any of four
widths. The standard symbology for retail food
packages in the United States.

Glossary

Variable Length Code

A code with a number of encoded characters within a
range, as opposed to a code with a fixed number of
encoded characters.

Vertical Bar Code

A bar code pattern presented in such orientation that
the symbol from start to stop is perpendicular to the
horizon. The individual bars are in an array appearing
as rungs of a ladder.

Visible Laser Diode (VLD)

A solid state device which produces visible laser
light.

Wedge

A device that plugs in between a keyboard and a
terminal and allows data to be entered by a keyboard
