As a keyboard wedge interface, the PSC scanner can be used with ter-
minals provided by most of the major terminal manufacturers. In
most cases, the PSC scanner is easily connected between the key-
board and display of the terminal. The use of Preamble/Postamble,
embedded keyboard function codes or keyboard function records
allow operation of the terminal without manual entry from the key-
board. In this mode of operations, the PSC scanner draws power from
the terminal.
The PSC scanner can be configured by the user for a serial communi-
cation output. In this mode, the scanner can be connected to any
device that accepts serial ASCII data at TTL voltage levels. RS232
voltage levels can be achieved by the use of an optional RS232 con-
version pod.
®
The PSC scanner may be configured at the factory with PSC’s
AutoSense® feature. AutoSense® operates with a passive stand for
hands-free operation. When the scanner is placed in the stand, it
becomes immediately active for reading any bar code label presented
to it. The user can remove the scanner from the AutoSense® Stand
and use it as a conventional hand-held scanner. When replaced in the
stand, the scanner reverts automatically to AutoSense®.
The PSC scanner can be configured by the user for Wand Emulation.
In this mode, the PSC scanner can be connected to any device that
accepts a wand signal input. Wand Emulation communication pre-
sents bar code data to a host device exactly as a wand does. This pre-
cludes the use of any option which adds information to the bar code
symbol data (preamble, for example). A typical example of this
would be to interface the scanner to a portable data terminal for
remote data collection.
Magnetic stripe reading capabilities are available with appropriate
cabling.
Your package should include a scanner, interface cable, User’s Man-
ual, and a plastic scanner holder.
The unit should be inspected immediately upon receipt to determine
if any damage has occurred during shipment. If damage has
occurred, a claim should be filed with the carrier immediately.
Retain the shipping box, since it should be used to return the scanner
to the factory for service.
In Keyboard Wedge mode the PSC scanner simulates keyboard key-
strokes. Whether a person has pressed a key on the keyboard or data
has been transmitted from the scanner is indistinguishable by the
host device. When the PSC scanner is not transmitting data to the ter-
minal the keyboard operates as if the PSC scanner was not attached.
Installation of the PSC scanner should be completed by a user who is
familiar with installing computer systems and cabling.
1. Turn off power to the terminal to which the PSC scanner will
be connected.
2. Verify that you received the correct cabling. The cable sup-
plied for keyboard wedge installation is referred to as a “Y”
cable.
3. Connect the modular plug to the PSC scanner. Insert plug
into the rectangular opening in the bottom of the scanner
handle.
4. Unplug the keyboard from the terminal and replug the key-
board into the short leg of the “Y” cable that mates with it.
5. Plug the remaining long leg of the “Y” cable into the terminal
where the keyboard was connected.
6. Arrange the fully connected unit so that all cables run freely.
If supplied, plug the connector from the external power supply into
the receptacle located on the housing connector. Then plug the power
supply into a power source.
If a detached Magnetic Stripe Reader (MSR) is to be used, plug the
connector into the MSR receptacle located on the housing connector.
Turn on the power to the terminal to which the PSC scanner is con-
nected. The unit will issue a series of beeps which are intentional and
indicate that the terminal/keyboard power-on reset routines have
been completed.
Proceed as follows:
1. Using the Keyboard Wedge Parameters menu given in the
Keyboard Wedge Parameters Section scan:
WEDGE MODE ENABLE (CE)
This sets the PSC scanner into a Keyboard Wedge interface
mode.
2. Select the terminal type by next scanning the appropriate
symbol for your terminal.
The PSC scanner provides the user with two different serial commu-
nications options: Serial TTL and Serial RS232 communications.
Serial TTL is a serial communications interface that uses TTL/CMOS
voltage levels ranging from 0 to 5 volts. The user can select a nor-
mally high (default setting) or normally low (inverted) voltage levels.
Serial TTL communications mode uses different cables than those
used in keyboard wedge applications. To configure the PSC scanner
in a Serial TTL mode, the user must have the appropriate cable with
the correct signal pinouts in order to interface the scanner to the host
terminal. To program the PSC for Serial TTL communications, the
user must first identify the serial communications parameters sup-
ported by the host terminal. Typical parameters are the baud rate,
parity and number of bits in the data word. These parameters are dis-
cussed in the section on Serial Communication Parameters. The PSC
scanner has the added versatility to enable the user to select the qui-
escent voltage levels for interfacing with terminals that require
inverted signals.
The PSC scanner can also be used in an RS232 environment by con-
verting the serial TTL voltage levels to RS232 voltage levels. For this
installation, the user needs an optional cable, an adapter pod, and a
power supply.
When the PSC scanner is operated with the RS232 adapter pod, the
same serial communications parameters apply as those used in a
serial TTL environment. The only difference is that the RS232 adapter
pod inverts the polarity of all the signals passing through it. There-
fore, the user needs to program the scanner for serial communication,
normal polarity (symbol CA). RS232 levels are available only in full
continuous power mode.
®
AutoSense® is a factory installed feature requested at time of order. It
provides for hands-free or handheld operation. AutoSense® is acti-
vated by scanning the Enable AutoSense® symbol. The scanner will
respond by emitting a continuous, low level red beam of light known
as the trigger beam. AutoSense® is deactivated by scanning the Dis-
able AutoSense® symbol.
When the AutoSense® feature is used with PSC’s AutoSense® stand
(specifically designed for standard and HP scanners), the user must
first attach the plastic scanner holder to the bracket of the stand as
shown in Figure 1, next page. The scanner is then mounted into the
holder. Insure that the trigger beam is aimed at the reflective tape
affixed to the stand. AutoSense® is now ready to automatically scan
bar code labels presented to it. When the trigger beam is broken by
the bar code label, the scan beam will automatically engage and
decode the bar code symbol. Any time the scan beam disappears,
whether by a decode or by a scan beam timeout, the automatic trigger
must be re-enabled by allowing the trigger beam to sense the reflec-
tive tape.
While AutoSense® is activated, the user is able to remove the scanner
from its holder and use it for handheld scanning operation. When the
scanner is removed from the AutoSense® holder, the trigger beam
will be broken and the scan beam will automatically be engaged. If
the scanner does not decode a bar code symbol, the scanning beam
will turn off after two to six seconds. Scanning is re-initiated by man-
ually pulling the trigger. When the scanner is replaced into the holder
AutoSense® will be automatically re-engaged when the trigger beam
senses the reflective tape.
®
®

®
To use this mode of operation properly, the user must first attach the
plastic scanner holder to the bracket of the stand as shown in
Figure 1. The (NO) Enable AutoSense® programming symbol is
scanned until the green “Good Decode” light blinks. This will acti-
vate the trigger screen. The scanner is then placed into the holder and
the user must check that the red laser beam is aimed at the reflective
label affixed to the stand. The AutoSense® is now ready to read labels
presented to it.
Figure 1. The PSC AutoSense® Stand
To operate the PSC scanner in Wand Emulation the user must first
turn off the powerto the host device and then detach the scanner from
the host device by removing the cable from the scanner.
The proper Wand Emulation cable must be connected between the
scanner and the portable data terminal for remote data collection. If
using an optional Smart Cable, the scanner automatically switches to
Wand Emulation. Specific Wand Emulation parameters may still
need to be set. If using a cable without Smart Cable switching, the
user must then configure the scanner to its Wand Emulation mode by
scanning the symbol CC.
This symbol activates the following default parameters:
Code type, bar code polarity, and transmission rate can each be set for
Wand Emulation. Menu symbols for these parameters are found in
the section on Wand Emulation Parameters.
When the user with a Smart Cable again connects to the host device,
the scanner will automatically revert to the original communication
mode. Without Smart Cable, scan the appropriate programming
symbol.
General setup parameters are divided into Keyboard Wedge options
(communication to host through the terminal keyboard), Wand Emu-
lation options (communication between the scanner and the host sys-
tem’s decoder), and Serial Communication options (communications
direct to the host system).

The following communication options are used to define how your
PSC scanner communicates with the host system through its serial
interface or its keyboard wedge interface.
A message transmitted from the scanner upon a successful decode
has the following format:
Some of these attributes, e.g., prefix, preamble, etc., may not be
required or may vary from one host system to another. The parameter
selection process allows you to tailor these elements for the particular
requirements of your host system. You may also program an inter-
character delay to prevent data overrun problems with your host ter-
minal.
Options specific to serial communications are:
Each of these options is discussed in greater detail in the section on
Serial Communication Parameters.
Three basic steps must be followed when selecting parameters for
your scanner.
1. Review this manual to be sure you understand the
terminology.
2. Review the requirements of your host system, with a techni-
cal expert from your company, if necessary. This will enable
you to determine if any of the factory default settings must
be altered.
3. Enable or disable the relevant parameters by scanning the
appropriate menus. This operation is described in more
detail in the following example.
Assume that the beeper volume is too loud at its default setting. To
change the beeper volume from its default value of loud to a setting
of low, locate the beeper volume bar code menu in the General
Parameters section. Then scan the label to the left of Beeper On, Vol-
ume Low. The correct label is reproduced below.
A successful scan is indicated by two short-high beeps. An unsuc-
cessful scan produces no beeps and requires you to rescan the Beeper
On; Volume Low bar code.
Most parameters are modified in this way, and you may resume nor-
mal bar code scanning when no further modifications are desired.
Some parameters require multiple scans to modify a setting; for
example, Intercharacter Delay. If you wish to set this parameter to 5
milliseconds (msec.):
1. Scan the bar code beside Intercharacter Delay = XX and lis-
ten for one short-high beep.
2. After the beep, scan the bar code beside 0 on the Digit Selec-
tion page and listen for one short-high beep.
3. Still at the Digit Selection page, scan the bar code for 5 (the
last argument in the command) and listen for two short
beeps.
Your PSC scanner does not have a distinct programming mode.
Instead, it automatically recognizes and reacts to the labels you scan.
If, for example, you scan INTERCHARACTER DELAY = XX and
then scan a normal data label, a normal tone is emitted in response to
the data label, and the programming command is ignored. No special
exit code is required to resume normal operations.
Serial transmission data is composed of three of four different ele-
ments, depending upon host system requirements. These elements
are the START bit, DATA bits (7 or 8 bits), OPTIONAL PARITY bits,
and STOP bit (s) (1 or 2 bits).
The PARITY bit is used for error detection (e.g., data altered in trans-
mission), but is not required by all systems. A parity bit, if required,
will be in one of the following four formats:
If your system requires a WORD length of 7 bits, one or two STOP
bits, and a PARITY check, select the appropriate option from Table 1.
If your system requires a WORD length of 8 bits, 1 or 2 STOP bits, and
PARITY check, select the appropriate option from the table below:
If your system requires a WORD length of 8 bits and 1 or 2 STOP bits,
but no PARITY, select the option below:
PARITY check is not possible with this combination of STOP bits and
WORD length.
Some receiving equipment requires inverted serial communication
signals.
Protocol controls data flow between your PSC scanner and a serial
host computer. If Protocol = XON/XOFF is selected, the scanner rec-
ognizes the ASCII XON/XOFF characters. The host may then stop
transmission with XOFF and resume with XON.
Controlled data flow is achieved between devices when the receiving
device sends ASCII XON/XOFF codes to the transmitting device. In
other words, when the receiving device is unable to accept data, it
sends on XOFF code to inform the host to temporarily suspend data
transmission.
When the receiving device “catches up,” it sends an XON code to
inform the host that it is again ready to accept data. An advantage of
this protocol is that additional hardware is not required for imple-
mentation; only transmit, receive, and signal ground are required.
Like XON/XOFF protocol, CTS protocol is a mechanism used to con-
trol data flow out. The CTS input is used to inform the scanner that
the host terminal is ready to accept scanned data. When CTS (+) pro-
tocol is selected, the scanner waits for a low level on its CTS input
before transmitting data. When CTS (-) is selected, the signal polari-
ties are reversed and a high level indicates data may be transmitted.
The CTS protocol may be programmed independently of the RTS pro-
tocol; however, the signal polarities must be the same. You may not
select CTS (+) and RTS (-).
The RTS output from the scanner may be programmed to operate in
one of three different modes. In the default mode RTS signals when
the scanner is ready to receive commands or data. In the second
mode, RTS is in a fixed state. In the third mode, RTS signals when the
scanner has data to transmit. The RTS modes are independent of the
CTS protocol. However, you must select the same active state for RTS
as for CTS. You may not select CTS (-) and RTS fixed low. If CTS (-) is
selected, then the active state for RTS will be high.
Another flow control option is available. If enabled, the stop/go pro-
tocol disables the trigger after every successful scan. The trigger is
then re-enabled with a serial ‘BG’ command in format
<STX><ESC>BG<ETX>.
The user may select one of three levels of serial buffering. With Full
Buffering (the default) selected, the scanner will place all scanned
labels into a buffer for transmission. This allows the operator to con-
tinue scanning even though the previous label may not have been
transmitted yet. Scanning will continue normally until the buffer is
full, then scanning will stop. Scanning will continue when enough
space is available for the current label.
When No Buffering is selected then scanning will be stopped until
the current label is completely transmitted.
When One Label Buffering is selected the scanner will allow the oper-
ator to scan one more label in addition to the label already in the
transmit buffer. In other words, one label may be scanned beyond the
label being transmitted.
The scanner can be programmed to send a no read message (‘NR’)
upon a scan that does not result in a good read.
In serial mode, most menu commands when scanned will provide a
confirmation message to the host along with the ACK. This feature
can be enabled or disabled.
External trigger operation enables an external device to control scan-
ning. External trigger is controlled by applying an external trigger
signal to the CTS input (with external triggering enabled). When
active, this signal causes scanning to begin just as if the scanner’s trig-
ger were depressed. Scanning continue until a label is decoded or the
external trigger signal is deactivated.
In the event of a decode, the trigger signal must be deactivated for a
minimum of 50 milliseconds before another scan can be attempted
(“tying” the trigger signal active does not cause continuous scanning
and decoding).
When EXTERNAL TRIGGER(+) is scanned, scanning begins when a
high level input is applied to the CTS input. Conversely, when
EXTERNAL TRIGGER(-) is scanned, scanning begins when a low
level is applied to CTS. When CTS is not connected, it is treated as if a
high level is applied. The voltage levels given are at the modular con-
nector. If an RS232 converter pod is used, then the levels are inverted.
Certain terminals and computers require an intercharacter delay to
simulate the effects of keystroke delays. Choosing an intercharacter
delay causes the characters to be sent at the slower speed required by
the device to which you are interfacing.
Interlabel delay allows user to program a delay between transmitted
labels.
Transmission mode selects either full or half duplex operation regard-
less of interface. In the half duplex mode, the decoded message is sent
simultaneously to the display and to the host computer. In the full
duplex mode, the message is sent to the host computer. In send mode,
the host always has the capability to send a message directly to the
LCD.
The advantage of the full duplex mode is that the display shows the
message received by the host. In the half duplex mode you can see
that the message has been sent but there is no confirmation that it was
received. The disadvantage of the full duplex mode is simply that the
host computer must be programmed to relay the message back to the
scanner.
To examine the configuration of your system, scan the appropriate
option.
When Option ZB is scanned, a list of currently programmed parame-
ters is sent to the display device. Scanning ZB may interfere with your
terminal software, depending on your application.
When Option ZC is scanned, the program version followed by car-
riage return-line feed characters (CR-LF) is sent in the format
<software name>SP<###> (WDHB 3.86, for example).
You may choose one of two Power Consumption modes. Option @A
supplies full power to the scanner at all times; Option @B allows the
unit to revert to a standby mode after a successful read. This mode is
a power conservation feature.
For a successful decode to occur when Laser Redundancy is enabled,
two laser scans of the bar code must match. Because the laser scans a
label many times a second, you will notice little or no change in the
speed of the decode. Laser redundancy can be used to enhance the
security of the bar code reader.
The scan beam will activate in response to a trigger pull. The beam
will automatically deactivate after a label is decoded. If a label is not
decoded., the scan beam will timeout and deactivate after several sec-
onds. Scan the following labels to control the length of the timeout.
Scan one of the options below to modify beeper operation.
Message formatting describes how to format the data (decoded
string) that is sent from the scanner to the host.
Prefixes, Suffixes, Preambles and Postambles are programmable
attributes that are transmitted along with the decoded label data to
the host device. These attributes are handled differently whether the
scanner is configured for serial mode or wedge mode. When config-
ured for wedge mode these attributes are sent as keystrokes. The
scanner automatically translates the ASCII characters into keystrokes
before sending data to the host. Refer to the keystroke translation
tables for non-printable ASCII characters.
A prefix is a subset of the preamble normally formatted to some
industry standard, i.e., it is represented by a specific ASCII code. An
example of a prefix is the STX (Start of Transmission) code.
A suffix is a subset of the Postamble. Like the prefix, it is normally
assigned a specific ASCII code. Examples of suffixes are CR (Carriage
Return) and LF (Line Feed).
Users also have the ability to select any ASCII character for use as a
suffix.
Scan the MJ label, then scan two labels from the Hexadecimal Con-
version Table representing the character needed for the suffix.
Certain specialized applications require a two character suffix of ETB
NUL. Scanning MI provides this.
Terminal ID characters are used to identify individual scanners when
more than one scanner is interfaced with the host system. Options
available are none (DISABLED) or digits 01 through 99.
A code identifier may optionally be transmitted with the message.
This option is provided so a host computer can identify the type of
bar code scanned, as well as the encoded information.
Scan Option FA to disable the code identifier.
Scan Option FB to enable the code identifier.
The table below shows the default code-identifier character assign-
ments. These can be changed using the procedure found in the Sym-
bology Identifier Section.
Preambles and Postambles are composed of up to four ASCII charac-
ters. Each ASCII character is encoded as two hexadecimal numbers.
Use the Hexadecimal Conversion Table in Appendix A to look up the
hexadecimal equivalent.
A Preamble is a string of characters that prefixes a message that is
transmitted to the host. The sequence and number of characters in a
Preamble is determined by the type of host system. Although not all
systems require a Preamble, those which do will only receive mes-
sages with the correct Preamble. The maximum preamble length is
four characters.
A Postamble is similar to a Preamble, except that it appended to the
message which is transmitted to the host. Its maximum length is also
four characters.
Serial Commands are only accepted by the PSC scanner when in
serial communications mode.
Serial commands take the form: STX ESC LT1 LT2 <optional param-
eters>ETX (Note: STX = ^B; ETX = ^C)
STX, ESC, and ETX are ASCII codes whose values are 02H, 1BH, and
03H, respectively. LT1 and LT2 are uppercase ASCII letters (commer-
cial A and @ are the same as those printed in earlier sections of this
manual under their corresponding menu bar code labels). The ESC
code that follows the STX code identifies this as a command. Some
commands require parameters such as minimum and maximum code
lengths, and strings of hexadecimal characters. When parameters are
required by the command, they immediately follow LT2. There are
never spaces within serial commands.
The scanner provides ACK/NAK protocol during serial program-
ming in order to provide feedback to the host computer which is pro-
gramming the scanner.
ACK/NAK protocol provides two vital functions. First, it provides
the host with positive acknowledgment that its commands are being
accepted and acted upon. Second, and perhaps more important, it
ensures that the host will not issue commands to the scanner more
quickly than the scanner can process them. For example, every time
the scanner receives a correct command, it modifies its internal
EEPROM, a function that takes about one second. At 9600 baud, the
host can easily issue commands to the scanner faster than they can be
processed. If after issuing each command the host waits to receive an
ACK or NAK code before issuing the next command, the scanner
cannot be overrun. If XON/XOFF or CTS/RTS Protocol is being used,
the scanner cannot be overrun by programming commands. How-
ever, the host is not provided with feedback as to the outcome of its
commands.
The ACK/NAK protocol is quite simple. Whenever the scanner
receives a correctly formatted command, it sends a confirmation mes-
sage followed by an ACK (06H) code.
If the scanner receives an unknown or improperly formatted code, or
if the required parameters are missing or out-of-range, it sends a
NAK (15H) Code.
Some of the commands in this manual should not be used as serial
commands because of the consequences they produce. All PSC scan-
ners use the same hardware components to implement both serial
communication and wand emulation. This means that all serial com-
munication functions are disabled during wand emulation, and vice
versa. Because of this, issuing any of the commands in Table 5 causes
the scanner to enter its Wand Emulation mode, thereby disabling
serial communication.
Furthermore, because the scanner acts upon a command and then
sends ACK or NAK, neither or these codes will be transmitted in
response to any of the above commands. In Table 5 only the com-
mand letters are listed; the complete command is prefixed with STX
ESC, and suffixed with ETX. Because it is not possible to set (via serial
command) two Wand Emulation parameters (emulation speed and
polarity, for example), scanners to be used in Wand Emulation envi-
ronments must be programmed by scanning labels from this manual.
When the scanner is programmed for standby power operation (@B),
the first character of the command is used to “wake-up” the scanner;
it is not properly received by the scanner’s CPU. Therefore, when
there is any possibility that the scanner is in standby mode, an extra
space code should be transmitted before STX to ensure the scanner is
“awake” before sending commands to it. If the scanner is not being
operated in standby mode, the space has no effect on commands
(space prefixed commands are properly decoded). Having sent the
space code to “wake-up” the scanner, a 150 to 200 millisecond pause
must be observed to allow the scanner’s CPU to complete its initial-
ization tasks, during which time it is unable to accept serial com-
mands before issuing the programming command. Failure to observe
this delay causes the scanner to ignore the incoming command.
All commands which affect serial communication are acted upon
immediately. Therefore, when changing communication parameters
(baud rate, word length, parity, etc.), the scanner will send the ACK
Code, using the newly implemented communication parameters.
There should be enough of a delay from the issuance of a communi-
cation parameter setup command for the properly programmed host
computer to modify its internal parameters and correctly receive the
ACK code sent by the scanner. This is due to the internal, one second
delay required for the scanner to update its internal EEPROM.
The decoder firmware makes no attempt to resolve conflicts between
serial programming commands and manually scanned menu labels.
If you plan to scan menu labels from the PSC Operator’s Manual, do
not attempt serial programming, and vice versa. Serial commands are
given priority over pending menu labels. For example, if you scan the
menu label SET I 2 of 5 MINIMUM LENGTH and the scanner is wait-
ing for a two-digit, minimum length code when a serial command is
issued, the serial command is acted upon and the pending manual
command SET I 2 of 5 MINIMUM LENGTH is ignored.
In normal Wedge Mode, the scanner emulates the keyboard exactly.
Should a scanned bar code label have alphabetic characters, they will
be presented to the computer as if they had been typed at the key-
board. They will be affected by the Caps Lock key. If the scanned
label has lower case alphabetic characters AND the Caps Lock key in
ON, then the alphabetics will be presented as upper case.
With the Caps Lock key ON, the user may required that the scanned
alphabetics are presented to the computer exactly as they are encoded
in the label. This is accomplished by scanning EO – Shift Alphabetic
Characters.
The PSC scanner is configured with Code 39, Code 128, UPC-A and
UPC-E not expanded symbologies. The user has the ability to enable
or disable any of the symbologies given below as well as UPC or
EAN supplements, I 2 of 5 with check digit, and Code 39 modulo 43
check digit.
The bar codes that can be read by PSC’s bar code scanners include:
The minimum label lengths are set to 1 character, except Code I 2 of
5, which is set to 14 characters; andCode S 2 of 5, which is set to 4
characters. The maximum label length for all symbologies is set to 32
characters. The user has the ability to set the minimum and maxi-
mum label lengths.
The symbol * indicates Default Parameter for serial mode. The sym-
bol # indicates Default Parameters for Wand Emulation. The symbol
@ indicates default parameters for Wedge Mode.
Scan Option QA to disable all UPC labels.
Option QB or Option QC enable both UPC-A and UPC-E. If UPC is
enabled, any UPC label, with or without supplement, is read. The
supplement is read if Option QB is selected, and it is ignored if
Option QC is selected.
Expanded UPC-E is disabled by scanning Option QH, or is enabled
by scanning Option QI.
Transmission of the first character in a UPC symbol (the number sys-
tem character) is disabled by scanning Option QD or enabled by
scanning Option QE.
Transmission of the last character in a UPC symbol (the check digit) is
disabled by scanning Option QF, or is enabled by scanning Option
QG.
Scanning QJ causes UPC-A labels to be transmitted as EAN-13
labels. Scanning QK disables this feature.
Scan Option RA to disable EAN/JAN (8 or 13 digit).
Option RB or RC enables both EAN 8 digit and EAN 13 digit. If
EAN/JAN is enabled, any EAN/JAN label, with or without supple-
ment, is read. The supplement is read if Option RB is selected and is
ignored if Option RC is selected.
Transmission of the first character in an EAN/JAN symbol (the num-
ber system character) is disabled by scanning Option RD, or is
enabled by scanning Option RE.
Transmission of the last character in an EAN/JAN symbol (the check
digit) is disabled by scanning Option RF, or is enabled by scanning
Option RG.
The minimum length of Code 39 messages is set by scanning Option
OH, followed by scanning two digits (01-32) from the Digit Selection
page.
The maximum length of Code 39 messages is set by scanning Option
OI, followed by scanning two digits (01-32) from the Digit Selection
page. If the minimum and maximum values are set equal, only codes
of that exact length are read.
The START and STOP characters in code 39 may either be transmitted
or suppressed. Scan Option OF to suppress transmission of the
START and STOP characters. Scan Option OG to enable transmission.
The following are only valid if CHK CHAR is enabled.
Scan Option PA to disable Interleaved Code 2 of 5.
Scan Option PB or PC to enable Interleaved Code 2 of 5.
The minimum length of Interleaved 2 of 5 messages is set by scanning
Option PD, followed by scanning two digits (02-32) from the Digit
Selection page. The value of the number you scan must be even.
The maximum length of Interleaved Code 2 of 5 is set by scanning
Option PE, followed by scanning two digits (02-32) from the Digit
Selection page. If the minimum and maximum values are set equal,
only codes of that exact length are read. The minimum and maximum
lengths must be even numbers.
Scan Option PF to disable Standard Code 2 of 5.
Scan Option PG to enable Standard Code 2 of 5.
The minimum length of Standard 2 of 5 messages is set by scanning
Option PH, followed by scanning two digits (01-32) from the Digit
Selection page.
The maximum length is set by scanning Option PI, followed by scan-
ning two digits (01-32) from the Digit Selection page. If the minimum
and maximum values are set equal, only codes of that exact length are
read. The minimum and maximum lengths must be even numbers.
Scan Option TA to disable Code 128.
Scan Option TB to enable Code 128.
The minimum length of Code 128 messages is set by scanning Option
TC, followed by scanning two digits (01-32) from the Digit Selection
page.
The maximum length of Code 128 messages is set by scanning Option

ning Option VD, or is suppressed by scanning Option VC.
Previous customization of other scanner features may have made
MSI/Plessey unavailable in some scanners. Consult Customer Ser-
vice for current capabilities or if you require a specific symbology.

Your PSC scanner can be programmed to add and/or change symbol-
ogy identifiers which might be required to be transmitted with mes-
sages. This feature is provided to allow a host computer to recognize
the type of bar code scanned, as well as the uncoded information. The
symbology identifiers are selected by scanning the desired program-
ming bar code symbol as defined below.
To change any single symbology identifier, scan the appropriate sym-
bology identifier bar code symbol and then scan the four hexadecimal
characters that represent the two bytes of the identifier. If you select a
one character identifier, then scan zero (null) twice for the second
character.
To find the hexadecimal values for the characters turn to the Hexa-
decimal Conversion Table. The procedure for selecting a symbology
identifier is identical to the procedure for selecting Preambles and
Postambles. The similar difference is that symbology identifiers are a
maximum of two characters, not four.
The FC programming symbol selects the symbology identifiers for
use with ICL 9518/9520 cash registers.
The FD programming symbol selects the symbology identifiers for
use with ICL 9518/9520 cash registers as given in Table 5.
Scan Option CC if you intend to operate the scanner in Same Code
Wand Emulation mode. If you want the label to be transmitted in
Code 39 scan Option CB.
Selected Option WA or WB.
Select the fastest speed your decoder will accept for best overall per-
formance by scanning one of the following labels.
Your PSC scanner can be prepared to synchronize the transmission of
scanned data to the timing sequence some terminals require to prop-
erly receive the data. This relationship is diagrammed in Figure 2.

Polarity may be selected as either active high or low by scanning XE
(high) or XF (low).
The Memory Module option is a factory installed feature that is
requested at time of order. The Memory Module option allows the
5300 series scanner to store decoded labels in an internal battery
backed up RAM. The stored buffered labels can then be transmitted
some time later. The user may also choose an interlabel transmission
delay in cases where the transmission rate of the buffered decoded
label is faster than the receiving equipment.
Switching to the Memory Module mode is achieved by scanning the
Enable Memory Module symbol. The Memory Module is cleared
every time Memory Module is enabled. While in Memory Module
mode, the scanner will store in its internal memory all scanned bar
code labels.
The user can transmit the stored labels by scanning the Send Memory
Module symbol. When the transmission rate is faster than the receiv-
ing equipment, the user can program a delay that will occur after
each label. The delay is programmed by scanning the Interlabel Delay
symbol (see the Intercharacter Delay page of the Setup Parameters
section), followed by two digits (see Digit Selection page) to set the
delay duration. The allowable range of values is 00 to 99, where 99
corresponds to a delay of 9.9 seconds.
In order to restore the scanner to normal operation, the user needs to
scan the Disable Memory Module label. Also the user may clear the
contents of the Memory Module by scanning the Clear Memory Mod-
ule symbol or by disabling and enabling Memory Module. Stored
labels are cleared whenever Memory Module is enabled.
The Marker Beam feature provides the user with a spotter beam for
improved aiming at distant bar code labels and/or in extremely
bright environments. You may also find a Marker Beam useful when
scanning through showcase glass or bar code menus with labels in
close proximity. This feature is available in all scanners without fac-
tory authorization.
To activate the Marker Beam, the user must also program the dura-
tion of the Marker Beam. First, the symbol Enable Marker Beam is
scanned and then followed by scanning one digit symbol from the
Digit Selections table. Each digit symbol represents the desired time
duration of the Marker Beam in milliseconds.
To deactivate the Marker Beam, the user must scan the Disable
Marker Beam symbol. For successful programming, the user must
hold the trigger down for two seconds after scanning.
The PSC Laser Scanners use a low-power, visible laser diode. As with
any bright light source, such as the sun, the user should avoid staring
directly into the light beam.

PSC Scanners are designed to provide trouble-free operation
throughout their lives. They contain no components that require peri-
odic maintenance. Optimum performance may be ensured by follow-
ing the preventive maintenance procedures suggested below. If
scanning performance declines, please follow these procedures.
A dirty scan window can impair scanning performance. When the
window appears to be dirty or smeared, clean it by wiping with a
slightly damp cloth or facial tissue. Water or a suitable cleaning solu-
tion such as Windex™ may be used on the cloth. The plastic case of
your scanner can also be cleaned in this manner.
Periodically inspect scanner cords and cables for wear and other
signs of damage which may interfere with the proper operation of the
unit. A badly worn cord or cable should be replaced immediately.
Replacement cords and cables can be obtained by contacting your
PSC Customer Service Representative.
Routinely examine scanners for signs of damage. A badly dented
enclosure may cause interference with internal components resulting
in damage to, or malfunction of the unit. Units with damage to the
enclosure should be returned to the factory for repair. Please refer to
Service and Warranty Section.
To use the conversion table:
1. Find each ASCII character in the tables on the following
pages and locate the corresponding bold hexadecimal-equiv-
alent character in the top row and in the left column of the
table. Notice, for example, that the ASCII character “Q” is
represented by the hexadecimal numbers 5 (top) and 1 (left).
2. Scan the bar code symbols that correspond to the hexadeci-
mal-equivalent characters. First scan the bar code symbol
that corresponds to the bold hex character at the top. Then
scan the bar code symbol that corresponds to the bold hex character
at the left.
For example, for the ASCII character “Q,” first scan the bar
code symbol labeled 5; then scan the bar code symbol labeled
1. If your preamble or postamble contains an “N”, first scan 4
and then E.
3. Repeat this procedure for each ASCII character you wish to
enter.
