1. Introduction
2. General Features
This manual contains all the information needed to operate and configure
the Pulsar C Barcode Scanner. It is divided into two parts. The first part of
this manual describes the operation and programmable features of the
scanner. The second part of this manual contains the setup barcodes used
to configure the scanner.
2.1 Buzzer
The buzzer of the scanner beeps differently to indicate various operating
conditions.
• Power On Beep: The Pulsar C scanner will issue a long beep to indicate
a successful power on.
The Pulsar C is one of the most versatile and flexible CCD barcode
scanners in the world. All the features and functions required for up to date
barcode reading are included. Owing to the compact design and extremely
low power consumption, this scanner provides for easy installation and high
product durability. The scanner will not only cater for the requirements
needed today, but also can fulfill your long- term needs. The major
functions and features of the Pulsar C are listed below:
• Good Read Beep: There are four volume levels and four beeping tones
(frequencies) that the user can select from to signify a good read. The
available options are:
Volume: Maximum/Loud/Medium/Minimum
Frequency: 8 / 4 / 2 / 1 kHz
• Error Beep: The scanner will issue a long beep with a low tone to
• Barcode Readability: Most popular barcode symbologies are supported.
• Support for negative barcodes.
indicate errors.
• Enter / Exit Configuration Beep: The scanner will issue 6 beeps upon
entering / exiting the configuration mode.
• Supports eight scan modes.
• Programmable Beeping Tone
• Setup Beep: In configuration mode, the scanner will normally beep twice
when a setup barcode is read. If the particular setup parameter needs
more than one read, the scanner will only issue a short beep to indicate
that there are more setup barcodes needed to complete the current
parameter setting.
• Dual Colour Indicator
• Interfaces Supported : KBD Wedge and RS232
• Programmable Code ID: Code ID can be individually configured for each
symbology.
• Programmable Length Code
• Programmable Prefix Code
• Programmable Postfix Code
• Character Substitution
2.2 Indicator
There is a dual colour indicator on top of the scanner. Normally it is off, and
will turn red when there is a good read. The indicator will be green when the
scanner is in configuration mode.
• Data Editing: Data can be reorganized according to user programmable
formats. Up to three data editing formats are supported.
2.3 Scan Modes
There are eight scan modes supported by the CCD scanner. The user can
choose the desired scan mode depending on the application requirements.
But, if the scanner is a switch-less scanner, only Continuous mode or
Testing mode can be selected (other scan modes involve trigger switch
interaction). The supported scan modes are described below.
• Extremely Low Power Consumption
• Auto Off Mode: The scanner will start scanning once the switch is
triggered. The scanning continues until either a barcode is read or a
preset scanning period (Scanner Time-Out Duration) is expired.
• Continuous Mode: The scanner is always scanning.
• Auto Power Off Mode: The scanner will start scanning once the
switch is triggered. The scanning continues until a preset scanning

period (Scanner Time-Out Duration) is expired. Unlike the Auto Off
mode, the scanner will continue to scan and the scanning period is
re-counted each time there is a successful read.
2.6 Reading Redundancy
This parameter is used to specify the levels of reading (decoding) security.
If No Redundancy is selected, only one successful decoding can make the
reading valid. If Three Times Redundancy is selected, it will take 3
successful decodes to make the reading valid. It is obvious that the more
redundancy the user selects, the higher the reading security and thus the
slower the reading speed. The user must compromise between decoding
security and decoding speed if the security feature is needed.
• Alternate Mode: The scanner will start scanning once the switch is
triggered. The scanner will continue scanning until the switch is
triggered again.
• Momentary Mode: The scanner will be scanning as long as the
switch is depressed.
2.7 Supported Symbologies
• Repeat Mode: The scanner is always scanning as per Continuous
Mode. But now the switch acts like a “re-transmit button”. If the
switch is triggered within 1 second after a good read, the same data
will be transmitted again without actually reading the barcode. This
“re-transmit button” can be triggered as many times as user desired,
as long as the time between each triggering does not exceed 1
second. This scan mode is most useful when the same barcode is to
be read many times.
Most of the popular barcode symbologies are supported. Each symbology
can be individually enabled or disabled. The scanner will automatically
discriminate and recognize all the symbologies that are enabled. The
supported barcode symbologies are listed below.
• Code 39 (Standard / Full ASCII)
• Italy Pharmacode
• French Pharmacode
• Industrial 25
• Interleave 25
• Matrix 25
• Codabar (NW-7)
• UPCA (with or without Add-on)
• UPCE (with or without Add-on)
• EAN8 (with or without Add-on)
• EAN13 (with or without Add-on)
• Code 93
• Laser Mode: This is the scan mode most often used on laser
scanners. The scanner will start scanning once the switch is pressed.
The scanning continues until either a barcode is read, the switch is
released or a preset scanning period (Scanner Time-Out Duration) is
expired.
• Test Mode: The scanner is always scanning. The scanner will
decode repeatedly even with the same barcode.
By default, the scan mode is Auto Off mode for scanners with trigger
switch, and is Continuous mode for switch-less scanners.
• Code 128
• EAN 128
• MSI
2.4 Re-read Delay
If the scanner mode is set to Continuous, Auto Power Off, Alternate, or
Momentary mode, the scanner will prevent accidentally reading the same
barcode twice by using a Re-read Delay (Blocking Time). The barcode
must be taken away from the scanning line longer than the Re-read Delay
to allow second reading of the same barcode. The Re-read Delay can be
set by the user.
• Plessey
2.8 Negative Barcodes
The Pulsar C can be configured to read negative barcodes. Normally,
barcodes are printed with the color of the bars darker than that of the
spaces. But for negative barcodes, they are printed in the opposite sense
just like negative films. The spaces of the negative barcodes are printed
with a color darker than that of the bars.
2.5 Scanner Time-out Duration
This parameter is used to limit the maximum scanning period when the
scan mode is either Auto Off Mode or Auto Power Off Mode. This time-out
duration is specified in units of second. The default time-out duration is ten
seconds.

3.1 Keyboard Wedge Interface
3.1.4 Capital Lock Status
3.1.1 Keyboard Type
In order to send alphabets with correct case, the scanner needs to know
the capital lock status of the keyboard. Incorrect settings may result in
reversed case of alphabets being transmitted. There are 3 options to this
parameter : On, Off, or Auto Detection. If this parameter is set to Auto
Detection, the scanner will automatically detect the capital lock status of the
keyboard before it transmits data.
The keyboard wedge interface is enabled by configuring/selecting keyboard
type. The supported keyboard types are listed below.
• PCAT - US, French German, Italian, Swedish, Norwegian, UK,
Belgium, Spanish, and Portuguese KBD
• PS2-30
• IBM 3477 TYPE (Japanese KBD)
• IBM 34XX,319X & Memorex Telex (122Keys)
3.1.5 Alphabets Transmission
User can choose how alphabets are sent by configuring this parameter.
The alphabets can be sent according to their case (the Case Sensitive
option), or the case is ignored (the Ignore Case option) when transmitting.
3.1.2 Keyboard Style - Alphabets
Keyboard layout style can be selected. There are three options to this
setting : default layout (US or English style), AZERTY layout, and QWERTZ
layout. This setting only works when the keyboard type selected is for US
keyboard. The scanner will make necessary adjustment when sending the
‘A’, ‘Q’, ‘W’, ‘Z’, ‘Y’, and ‘M’ character according to this setting.
3.1.6 Digits Transmission
User can choose how the scanner transmits digits by configuring this
parameter. The scanner can transmit digits by using the alphanumeric key
or by using the numeric key pad. The Num Lock status of the keyboard
should be ON if numeric key pad option is selected.
3.1.3 Keyboard Style – Digits
There are two digit layout styles as shown on the following figures. One has
its digit keys on top (upper row), the other has them on bottom (lower row).
Numeric Key Pad
Configuring this setting can change the layout of the digits. There are three
options: Default, Lower Row, and Upper Row. The scanner will make
necessary adjustment when sending digits according to the setting value of
this parameter. This setting is meant to be used with the above setting
(Keyboard Style – Alphabets) and perhaps Character Substitution setting,
when support to languages not available on the scanner is needed.

An inter-character delay of 0 to 255 ms can be configured to match the
computer response time of the keyboard interface. The delay time
configured is inserted between transmitting every character. The longer the
delay time configured, the slower the transmission speed will be. The inter-
character delay is zero by default.

3.2 RS232 Interface
The user can select the desired, flow control, baud rate, parity, and data
bits to be used in this output interface.
4. Symbology Parameters
This section describes user configurable parameters which are pertaining
to barcode symbologies.
3.2.1 Baud Rate / Parity / Data Bits
The supported baud rate, parity, and data bit are listed below.
4.1 Code39
• Standard / Full ASCII Code 39: User can choose to read either
Standard Code 39 or Full ASCII Code 39 by configuring this
parameter.
• Baud Rate : 38400 / 19200 / 9600 / 4800 / 2400 / 1200 / 600 / 300
• Parity : None / Even / Odd
• Data bit : 8 / 7
• Start/Stop Transmission: This parameter specifies whether the
start/stop characters of Code 39 are included in the data being
transmitted.
3.2.2 Flow Control
The user can further configure the flow (handshake) control method to be
used. The available options are listed below.
• Checksum Verification: This parameter specifies whether the
scanner will perform checksum verification when decoding barcodes.
If the checksum is incorrect, the barcode will not be read.
• No Flow Control
• Scanner Ready : The scanner will activate the RTS signal after
power on. After each good read the scanner will then wait for the
CTS signal becomes active. The data will not be sent until CTS
signal becomes active.
• Data Ready : The RTS signal will be activated after each good read.
The scanner will then wait for the CTS signal becomes active. The
data will not be sent until CTS signal becomes active.
• Inverted Data Ready : It is like the Data Ready flow control, but the
RTS signal level is inverted.
• Checksum Transmission: This parameter specifies whether the
checksum character are included in the data being transmitted.
4.2 Italy / French Pharmacode
For Italy /French Pharmacode, there is always a checksum character
included in the barcode. So the checksum verification is always performed
when decoding these symbologies. User though can choose whether the
checksum character is to be transmitted or not. The start / stop
transmission of this code shares the same setting of Code 39.
• Checksum Transmission: This parameter specifies whether the
3.2.3 Inter-Character Delay
checksum character is included in the data being transmitted.
An inter-character delay of 0 to 255 ms can be configured to match the
computer response time. The delay time configured is inserted between
transmitting every character. The longer the delay time configured, the
slower the transmission speed will be. The inter-character delay is zero by
default.
4.3 Industrial / Interleave / Matrix 25
• Start / Stop Selection: This parameter provides the readability of all
2 of 5 symbology variants. For example, flight tickets actually use an
Industrial 25 barcode but with Interleave 25 start / stop. In order to
read this barcode, the start / stop selection parameter of Industrial
25 should set to ‘Interleave 25.
• Checksum Verification: This parameter specifies whether the
scanner will perform checksum verification when decoding barcodes.
If the checksum is incorrect, the barcode will not be read.
• Checksum Transmission: This parameter specifies whether the
checksum character is included in the data being transmitted.
• Code Length Qualification: Because of the weak structure of the 2
of 5 codes, a partial scan has a high probability of decoding as a
valid but shorter 2 of 5 codes (known as short scan). To prevent this
8

kind of undesired reading, the Code Length settings can help to
insure that the correct code is read by qualifying the allowable code
length. Code length parameters can be configured in two ways:
Fixed Code Length or Max / Min code length. If the fixed code
length is selected, up to 2 fixed lengths can be specified. And if max /
min code length is selected, the max length and the min length must
be specified, and the scanner will only accept those codes with
lengths fall between max / min length specified.
4.6 EAN8
• Convert to EAN13: If this parameter is enabled, the EAN8 read will
be expanded into EAN13, and the following processing will follow the
parameters configured for EAN13.
• Checksum Transmission: If this parameter is enabled, the
checksum character will be included in the data being transmitted.
4.7 UPCA
4.4 Codabar
• Convert to EAN13: If this parameter is enabled, the UPCA read will
be expanded into EAN13, and the following processing will follow the
parameters configured for EAN13.
• Start/Stop Transmission: This parameter specifies whether the
start/stop characters of Codabar are included in the data being
transmitted.
• System Number Transmission: If this parameter is enabled, the
system number will be included in the data being transmitted.
• Start / Stop Selection: Four different start / stop pairs can be
selected as start / stop characters as listed below.
• Checksum Transmission: If this parameter is enabled, the
checksum character will be included in the data being transmitted.
abcd / abcd
abcd / tn*e
ABCD / ABCD
ABCD / TN*E
4.8 EAN13
• ISBN / ISSN Conversion: If these parameters are enabled, the
scanner will convert the code read into ISBN or ISSN code if the
formats are correct (EAN13 codes start with 978 or 979 for ISBN,
and 977 for ISSN).
4.5 UPCE
• System Number Selection: The UPCE comes with 2 options:
System Number 0 and System Number 1. These two differ in the
way data are encoded. The system number 1 is the new UPCE
extension to the ordinary UPCE (system number 0). User can have
the choice of enabling both system numbers, or just system number
0.
• Checksum Transmission: If this parameter is enabled, the
checksum character will be included in the data being transmitted.
4.9 MSI
• Checksum Verification: Three kinds of checksum calculations can
be implemented into MSI code: Single Modulo 10, Double Modulo
10, or Modulo 11 & 10 checksum. If the checksum character is
incorrect, the barcode will not be read.
Warning: Because of the way system number 1 is encoded, if both
system numbers are enabled, user might suffer from short scanning
UPCA or EAN13 into UPCE system number 1 barcodes.
• Convert to UPCA: If this parameter is enabled, the UPCE read will
be expanded into UPCA, and the following processing will follow the
parameters configured for UPCA.
• Checksum Transmission: User can control how the checksum is
transmitted by configuring this parameters.
1) Transmitted
2) Last digit not transmitted
3) Last 2 digits not transmitted
• System Number Transmission: If this parameter is enabled, the
system number will be included in the data being transmitted.
• Checksum Transmission: If this parameter is enabled, the
checksum character will be included in the data being transmitted.
• Code Length Qualification: Because of the weak structure of the
MSI code, a partial scan has a high probability of decoding as a valid
but shorter MSI codes (known as short scan). To prevent this kind of
undesired readings, the Code Length settings can help to ensure
that the correct code is read by qualifying the allowable code length.
Code length limitations can be set in 2 ways: Fixed Code Length

and Max/Min code length. If the fixed code length is selected, up to
2 fixed lengths can be specified. And if max / min code length is
selected, the max length and the min length must be specified, and
the scanner will only accept those codes with lengths fall between
max / min length specified.
5. Data Output Format
Data read by the scanner will be processed in the following sequence (RS-
232 and Keyboard Wedge).
1) The character substitution is performed on the barcode data.
2) The Code ID and the Length Code are inserted at the beginning of the
data as shown below.
[Code ID] [Length Code] [Data]
3) The resulting data of step 1 will be processed by the editing formats. For
details, please refer to the section “Data Editing”.
4.10 Plessey
• Convert to UK Plessey: If this parameter is enabled, the scanner
will change each occurrence of the character ‘A’ into character ‘X’ in
the code.
4) And finally the Prefix Code and the Postfix Code will be added before
transmission.
[Prefix Code] [Resulting Data of Step 3] [Postfix Code]
• Checksum Transmission: If this parameter is enabled, the
checksum characters (two characters) will be transmitted together
with data.
5.1 Character Substitution
There are three character substitution settings on the scanner. These
settings are configured on a character base, i.e, a specific character is to
be substituted by an another character. The character substitution is
performed on every occurrence of the characters specified in these
settings. Be aware, the substitution is performed only on the barcode itself
(exclude Prefix Code, Postfix Code, Code ID, Length Code or any
Additional Field) and is performed before editing mode processing.
If only the character to be replaced is specified, every occurrence of that
character in the barcode will be taken away.
5.2 Prefix / Postfix Code
Up to four characters of prefix / postfix code can be configured for the
scanner.

6. Data Editing
5.3 Code ID
The Pulsar C provides advanced data editing functions for data formatting.
Data editing is performed according to user configured editing formats. Up
to three editing formats can be configured.
Up to two characters of Code ID can be configured for each symbology. To
minimize the Code ID configuration efforts, the scanner provides five
predefined Code ID Sets that user can select from. User can first select one
of the Code ID Sets and then make desired modifications. The pre-defined
Code ID Sets are shown below.
Data is divided into fields by user specified rules. These fields together with
user configurable additional fields constitute the data actually sent to the
host computer. The detailed descriptions and the configuration procedures
of the editing format are described in this section.

6.2 Restore Default Format
UPCA
After the editing format to be configured is selected, user can read the
“Restore Default Format” label to put the editing format back to default
setting. The default settings of the editing format are listed below.
5.4 Length Code
Two digits Length Code representing the length of data (character count)
can be inserted in front of data being transmitted. This Length Code
parameter can be individually enabled or disabled for each barcode
symbology.
• Applicable Code Type: All
• Applicable Length: Both max and min length are zero.
• Matching string: Empty
• Matching String Location: 0
• Total number of field: 1
• Field Setting: Not Configured
• Additional Fields: Empty
• Field Transmission Sequence: F1
6.3 Applicable Conditions
Three applicable conditions can be configured to qualify whether the data
read by the scanner can be processed by the particular editing format. Data
editing will not be performed unless all three applicable conditions are met.
The configurable applicable conditions are described below.
14
13
Download from Www.Somanuals.com. All Manuals Search And Download.
• Code Type: This parameter specifies the code type of the data
eligible for data editing. Multiple code types can be specified for this
parameter.
6.6 Additional Fields
User can create up to five additional fields for each editing format. Each
additional field can have at most four characters. The additional fields are
numbered AF1 to AF5 accordingly.
• Data Length: This parameter specifies the length (character count)
of the data eligible for data editing. It is specified in the range format.
The length of the data must fall between max and min length limits. If
the max length and the min length configured is both zero, the
scanner will not perform this length qualification.
6.7 Field Transmission Sequence
After the data fields and the additional fields are configured, user can now
program the transmission sequence of these fields that comprise the final
data. The “Start” label must be read before assigning the field transmission
sequence. And then the desired field transmission sequence can be
specified. The scanner will transmit the fields in the order (sequence) user
programmed when sending data. The field transmission sequence can be
assigned in any desired order and fields can also be assigned multiple
times. The maximum number of fields can be assigned is twelve. After the
sequence has been assigned, the “End” label must be read to complete the
setting.
• Matching String and its Location: User can specify a particular
character string (up to four characters) that must appear in the data
that is eligible for data editing. User can also specify where
(character position, starts from one) this string should appear in the
data by configuring the matching string location. If the location
specified is zero, the scanner only checks for the existence of the
matching string in the data. To disable the matching string
qualification, just leave the matching string empty.
6.4 Total Number of Fields
6.8 End of Format Programming
Data can be divided into at most 6 fields. The total number of fields
configured must be correctly specified. The fields are numbered from F1 to
F6 accordingly, but only F1 to F5 can be configured. Please note that, the
number of fields can be configured is always one less than total number of
fields specified. The extra data characters beyond the last field configured
will be automatically assigned to the next field. That is, if three fields are
configured for the editing format, the data characters after F3 will be
assigned to F4 automatically. This feature is quite useful especially
when data of variable length is processed by editing formats.
After all the desired parameters are configured, the “End of Format
Programming” label must be read to conclude the programming of the
editing format. This label is located at the bottom of every even page in the
“Editing Format Parameters” section of the configuration manual.
6.9 Activate Data Editing Formats
Before data can be processed by a particular editing format, that format
must be enabled. The editing formats can be enabled or disabled
individually.
6.5 Dividing Data into Fields
6.10 Exclusive Data Editing
Data eligible for editing format is divided into fields according to user
specified rules. The rule for each field can be configured in two ways.
If this parameter is enabled, all data read by the scanner must be
processed by the editing format. If the data is not eligible for all enabled
editing formats, the scanner will not accept the reading and the data will not
be transmitted.
• Field Terminating String: The field dividing rule can be configured
by specifying the field terminating string. The field terminating string
configured can be up to two characters. The scanner will search for
the occurrence of this particular string in the data for the field. The
field terminating string is always included in the field. User though,
has the option of discarding this terminating string.
6.11 Programming Examples
Example 1: Extracts data from the 10th character to the 19th character.
Total Number of Fields: 3
• Field Length: The field dividing rule can be configured by simply
specifying the field length. The scanner will assign the next specified
number of characters into the field.
Field 1: Divide field by field length, set field length to 9
Field 2: Divide field by field length, set field length to 10
Field Transmission Sequence: F2

7. Configuring your Pulsar C
Configuring the Pulsar C is done by reading the setup labels contained in
the Configuration Manual (the second part of this manual). This section
describes the procedure of configuring the scanner. Some configuration
examples are also given in this section for illustration.
Example 2: Extract the date code, item number, and quantity information
from barcodes. Data is encoded in the barcode like this: From the first
character to the 6th character is the date code. From the 7th character is
the item number, its length is not fixed but is delimited by a ‘-’ character.
After the ‘-’ character is the quantity information.
7.1 Enter Configuration Mode
To start the configuration, the “Enter Setup” label must be read. This will
put the scanner in the configuration mode. The scanner will respond with 6
beeps and the indicator will turn green after the label is read. This “Enter
Setup” label is located at the bottom of almost every even page of the
Configuration Manual.
Data should be transmitted like this: Item number goes first, then a TAB
character, and then the date code, and then another TAB character and
finally the quantity.
Total Number of Fields: 3
7.2 Default
All the parameters of the scanner will return to their default values by
reading the “Default” label. The scanner will beep twice when the “Default”
label is read.
Field 1: Divide field by field length, set the field length to 6.
Field 2: Divide field by field terminating string. Set terminating string to
‘-’, and discard the terminating string.
Additional Field 1: Set to one TAB character.
Field Transmission Sequence:
7.3 List Setting
The current setting of all scanner parameters can be sent to the host
computer for user inspection. The listing is separated into ten pages. User
can select the page of interest by reading the “Page x” label. The scanner
cannot list setting, if Wand Emulation interface is configured.

7.4 Setting Parameter Values
For most of the parameters, only one read is required to set them to new
values. The scanner will respond with two beeps when these parameters
are configured. But for some special parameters, multiple reads are
required to complete the setting. The scanner will respond with a short
beep if the configuration of the parameter is still not complete. These
parameters usually refer to a numeric value or a string of characters, such
as keyboard type, inter-character delay, prefix / postfix code, etc..

For these kinds of parameters, the label of the parameter to be configured
must be read first. Then the labels comprising the numeric value or
character string are read. Finally, the “Validate” label must be read to
complete the setting. The scanner will respond with two beeps when the
“Validate” label is read.

Parameter Label
Decimal Label
Two Hexadecimal Labels
"Validate" Label
For example, to configure the Prefix Code to be “AB”, the “Prefix Code”
label is first read, and then the hexadecimal digit labels “4”, “1”, “4”, and “2”
are read, and finally, the “Validate” label to complete the setting.
"Validate" Label
For example, to configure the Inter-Character Delay to be 15 ms, the “Inter-
Character Delay” label is first read, and then the decimal digit labels “1” and
“5”, and finally, the “Validate” label to complete the setting.
7.4.3 Key Type/Status Setting
The key type/status is specified in character basis. Each character
programmed is by default of Normal key type. A character of normal key
type can have associate status settings (add Shift/Control/Alternate).
7.4.2 Character String Parameters
Each character programmed for the character string parameters is
represented by two hexadecimal digits. The two hexadecimal digits usually
comprise a value which is the ASCII code equivalence of the character
being programmed.
Whereas a character of Scan Code type may not have any associate key
status settings.
• Normal Key Type: When this label is read, the scanner will assume
the following hexadecimal digits are the ASCII code of the character
being programmed. And it will also clear all the associate key status
settings made to the current character.
Beside the two hexadecimal digits, there is an optional key type/status can
also be specified for each character of the string parameters. This optional
key type/status can only be specified for some particular parameters when
keyboard interface is used. These parameters are: Prefix Code, Postfix
Code, Code ID, and Additional Fields of Editing Formats.
• Scan Code: When this label is read, the scanner will assume the
following hexadecimal digits are the scan code value of the character
being programmed.
The available key type/status settings can be selected will be described
briefly. The configuration procedures for character string parameters are
shown below.
• Add Shift: The Shift key will be sent together with the character
programmed.
• Add Control (L): The left Control key will be sent together with the
character programmed.
• Add Alternate (L): The left Alternate key will be sent together with
the character programmed.

character programmed.
• Add Alternate (R): The right Alternate key will be sent together with
the character programmed.
For example, to program the Prefix Code to be “Ctrl-Shift-B”, “C”, the
programming sequence should be:
France
1) “Prefix Code” label
2) “Add Control (L)” label
3) “Add Shift” label
4) “4” of the hexadecimal digit
5) “2” of the hexadecimal digit
6) “4” of the hexadecimal digit
7) “3” of the hexadecimal digit
8) “Validate”

Note: In internal representation of the characters that are specified with
either scan code or associate key status, occupy two normal character
space each. So the maximum number of characters can be configured for a
string parameter will decrease, if these character specifications are used.

7.5 Exit Configuration Mode
Both the “Update”, and the “Exit Setup without Changes” labels will exit the
scanner from configuration mode when they are read. These two labels
differ in whether to keep the new settings on the scanner or not, as their
names suggest. The scanner will respond with 6 beeps and restart itself, if
either label is read.
