Introduction
Keyboard Wedge Mode
As a keyboard wedge interface, the PSC scanner can be used with terminals 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.
Serial Communications Mode
The PSC scanner can be configured by the user for a serial communication 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.
AutoSense® Mode
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
®
.
Wand Emulation Mode
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 precludes 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 Reader
Magnetic stripe reading capabilities are available with appropriate
cabling.
2 User’s / Programming Guide
Unpacking
Your package should include a scanner, interface cable, User’s Manual, 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.
Installation
Keyboard Wedge
In Keyboard Wedge mode the PSC scanner simulates keyboard keystrokes. 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.
Cable Installation
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.
06656 3
Connecting the Power Supply
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.
Connecting a Magnetic Stripe Reader
If a detached Magnetic Stripe Reader (MSR) is to be used, plug the
connector into the MSR receptacle located on the housing connector.
Terminal Power-Up Sequence
Turn on the power to the terminal to which the PSC scanner is connected. The unit will issue a series of beeps which are intentional and
indicate that the terminal/keyboard power-on reset routines have
been completed.
Programming for Terminal Type
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.
NOTE
If this is a first-time installation, it is NECESSARY to program the PSC scanner for use with the connected terminal.
NOTE
Scanning Reset to Default (ZA) will cause the PSC scanner to revert to Keyboard Wedge mode with a PC-AT terminal type.
4 User’s / Programming Guide
Serial Communications
The PSC scanner provides the user with two different serial communications options: Serial TTL and Serial RS232 communications.
Serial TTL Mode
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.
Serial RS232 Mode
The PSC scanner can also be used in an RS232 environment by converting 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.
06656 5
AutoSense® Operation
AutoSense® is a factory installed feature requested at time of order. It
provides for hands-free or handheld operation. AutoSense
®
is activated 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.
NOTE
When the scanner is powered from a battery, such as in a
hand-held terminal, AutoSense
®
should be disabled. In a
battery powered application, the user is strongly recom
mended to use the power conservation feature of scanner operation. Power conservation reduces power draw
from the battery between scans to extremely low levels.
AutoSense
®
will function only in full power mode.
6 User’s / Programming Guide
NO Enable AutoSense
®
NN Disable AutoSense
®
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 activate 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.

Wand Emulation Operation
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.
CC Same Code Wand Emulation
This symbol activates the following default parameters:
Code Type = Same Code Wand Emulation
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.

Serial Communication and Wedge Options
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 terminal.
Options specific to serial communications are:
Baud Rate Protocol

Parameters Selection Guidelines
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 technical 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.
Examples
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.
AB Beeper On; Volume Low
A successful scan is indicated by two short-high beeps. An unsuccessful 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 normal 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.):
NOTE
When enabling or disabling a parameter, be sure the scanner
beam illuminates only one bar code symbol at a time. The
layout of this manual minimizes accidental multiple-label
scanning.
12 User’s / Programming Guide
1. Scan the bar code beside Intercharacter Delay = XX and listen for one short-high beep.
2. After the beep, scan the bar code beside 0 on the Digit Selection 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.
06656 13
Serial Communication
Reset Default
To program the communication mode for serial asynchronous communication, scan the following label:
CA Select Serial Output
Baud Rate
There are seven standard serial communication baud rates to select
from. Your scanner and the serial host computer must be set to the
same baud rate. Select the correct rate.
DA Baud Rate = 300 Baud
DB Baud Rate = 600 Baud
DC Baud Rate = 1200 Baud
DD Baud Rate = 2400 Baud
DE Baud Rate = 4800 Baud
DF Baud Rate = 9600 Baud *
DG Baud Rate = 19200 Baud

Data Transmission
Serial transmission data is composed of three of four different elements, 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 transmission), 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.

Some receiving equipment requires inverted serial communication
signals.
CD Inverted Serial Communications
Communications Protocol
XON/XOFF
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.
Table 3. 8 Bit, No Parity
8 1 None
EM

EN
06656 17
CTS
Like XON/XOFF protocol, CTS protocol is a mechanism used to control 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 (-).
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.
NOTE
The specified levels are at the modular connector and are
inverted when using an RS232 converter pod.
HA
CTS Protocol = None*
RTS low indicates scanner ready to
receive data
HB Protocol = XON/XOFF
HC Protocol = CTS (-)
18 User’s / Programming Guide
Another flow control option is available. If enabled, the stop/go protocol disables the trigger after every successful scan. The trigger is
then re-enabled with a serial ‘BG’ command in format
<STX><ESC>BG<ETX>.

HH RTS always high
HI
RTS high indicates scanner ready

06656 19
Label Buffering
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 operator 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.
NE Full Buffering
NF No Buffering
NG One Label Buffering
No Read Option
The scanner can be programmed to send a no read message (‘NR’)
upon a scan that does not result in a good read.
NX Enable No Read
NY Disable No Read *
20 User’s / Programming Guide
Menu Commands Parameter Messages
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.
BA Enable Parameter Messages *
BB Disable Parameter Messages
External Trigger Operation
External trigger operation enables an external device to control scanning. 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.

General Parameters
Intercharacter Delay
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.
GA No Intercharacter Delay
GB Intercharacter Delay = XXMEC
Interlabel delay allows user to program a delay between transmitted
labels.
GC No interlabel delay *@
GD Set interlabel delay 0-9.9 seconds
NOTE
To set Intercharacter Delay to other then zero, scan the
label below and then scan two separate digits from the
Digit Selection page (99 maximum).
NOTE
Intercharacter delay cannot exceed 99 milliseconds.

Transmission Mode
Full Duplex or Half Duplex
Transmission mode selects either full or half duplex operation regardless 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.
NA Transmission Mode = Full Duplex
NB Transmission Mode = Half Duplex *#
System Status
To examine the configuration of your system, scan the appropriate
option.
When Option ZB is scanned, a list of currently programmed parameters is sent to the display device. Scanning ZB may interfere with your
terminal software, depending on your application.
NOTE
This section pertains only to models with a Liquid Crystal Display (LCD)
NOTE
For models which do not have an LCD, parameter selections NA and NB have no effect.
06656 23
ZB Display Configuration
When Option ZC is scanned, the program version followed by carriage return-line feed characters (CR-LF) is sent in the format
<software name>SP<###> (WDHB 3.86, for example).
ZC Transmit Version Number
Power Consumption
You may choose one of two Power Consumption modes. Option @A
supplies full power to the scanner at all times; Option @B allows the

Laser Redundancy
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

Message Formatting
Message formatting describes how to format the data (decoded
string) that is sent from the scanner to the host.
Prefixes and Suffixes
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.
NOTE
The programmable options DO NOT apply in Wand Emulation.

Prefix
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.
IA Prefix = None*#
IB Prefix = STX
IC Prefix = SOH
Suffix
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).
MA Suffix = None #
MB Suffix = ETX
MC Suffix = CR
MD Suffix = LF
ME Suffix = HT
06656 27
MF Suffix = CR and LF *
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 Conversion Table representing the character needed for the suffix.
Certain specialized applications require a two character suffix of ETB
NUL. Scanning MI provides this.
MI Select Suffix = ETB NUL

Preamble or Postamble Selection
Preambles and Postambles are composed of up to four ASCII characters. Each ASCII character is encoded as two hexadecimal numbers.
Use the Hexadecimal Conversion Table in Appendix A to look up the
hexadecimal equivalent.
Preamble
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.
KA Preamble = None*#
KB Enter Preamble
IMPORTANT
Scan Enter Preamble to enter a Preamble, then refer to the Hexadecimal
Table in Appendix A.
Postamble
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.
NOTE
If you select a Preamble or a Postamble you must scan
four ASCII characters, even if the Preamble or Postamble
is less than four characters in length. This is done by
scanning in null (NUL) characters for the additional char
acters. For example, if your Preamble is “AB” (in ASCII
code), scan A, then B, then two null characters, or 4,1, 4,2
0,0 0,0 hexadecimal.

Serial Commands
General Serial Command Format
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.
ACK/NAK
The scanner provides ACK/NAK protocol during serial programming in order to provide feedback to the host computer which is programming 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.
32 User’s / Programming Guide
Beeper Off CR-LF Ack
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.
Serial Commands to Use with Caution
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.

STX ESC PC ETX Enable I 2 of 5 with check digit
STX ESC PD12 ETX Set I 2 of 5 minimum length to 12
STX ESC PE14 ETX Set I 2 of 5 maximum length to 12

STX ESC LB61626364 Set Postamble to ‘abcd’
CB Wand Emulation, Code 39 Output
CC Wand Emulation, Same Code Output
06656 33
Power Standby and Serial Commands
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 commands before issuing the programming command. Failure to observe
this delay causes the scanner to ignore the incoming command.
Communication Parameter Changes
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.
Manual Scanning Interaction
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.

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

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.
NOTE
The stored data in the Memory Module cannot be transmitted through the Wand Emulation output.
CAUTION
The Memory Module feature is to be used only with the
Memory Module mode. When used with scanners without
this optional mode, programmed instructions will be
damaged.

Marker Beam
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 duration 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.

Scanner Labeling
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.

Maintenance
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 following the preventive maintenance procedures suggested below. If
scanning performance declines, please follow these procedures.
Cleaning
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.
Inspection
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.
NOTE
Never use solvents (e.g., alcohol) on the enclosure; they
may damage the finish of the scanner.

Appendix A
Hexadecimal Conversion Table
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 hexadecimal-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.
