PRODUCT OVERVIEW
The HS1250 , a compact high-performance scanner, is designed to
mount horizontally in your counter, leaving valuable checkstand ‘real
estate’ clear for items and workspace. Designed for grocery and
hypermarket applications, the HS1250's cast aluminum construction
and rugged top design makes it ideal for high volume installations as
well as moderate to low volume applications such as variety, drug and
convenience stores.
Slide-through scanning enhances productivity and throughput, while
eliminating the need to lift items being scanned. The HS1250 also
provides a connection for an optional undecoded handheld scanner,
such as the PSC model SP400 , allowing heavy or large items to be
scanned without removal from the shopping cart.
The HS1250's sturdy design allows a couple of different mounting
options. Power to the scanner is supplied via a remote AC/DC power
supply, adding to the ease of installation. Advanced hardware and
software afford the highest levels of scanning performance in the
smallest possible package.
HS1250 features include:
• aggressive scan pattern minimizes the need for label
orientation
• flush horizontal mounting leaves the entire counter work
space clear
• modular design allows easy use within multiple applica-
tions
• programmable features let the user customize scanner
settings, optimizing performance and tailoring advanced
features for each installation
• automatic shutdown activates when the scanner is left
idle, prolonging scanner life and conserving power
• integrated motion sensor "knows" when you are ready to
use it

MANUAL OVERVIEW
International symbols are used throughout this manual to provide a
simple visual indication of the information being discussed. In most
cases, each topic's name is preceded by a simple graphic.
For example is the internationally recognized symbol for a speaker.
Appendix A, Symbol Definitions, shows all the symbols used in this
manual and describes their meaning. These symbols come from the
International Electrotechnical Commission (IEC) Publication 417G,
Graphical Symbols for Use on Equipment.
OPERATIONAL OVERVIEW
The scanner has three operational states: Normal Mode, Sleep Mode
and Programming Mode.
NORMAL MODE
Normal Mode is the scanner state when it reads barcodes and sends
label data to the host. When the scanner is idle in Normal Mode for a
prolonged period of time, it transitions into Sleep Mode to conserve
power and prolong scanner life.
SLEEP MODE
Sleep Mode is the term used to describe the scanner's condition after
the motor and/or laser have automatically switched off due to a
prolonged period of inactivity.
PROGRAMMING MODE
Entering Programing Mode allows you to change scanner features
such as the speaker volume, scanner to host interface parameters,
barcode symbologies, and laser and motor time-outs. When the
scanner is in Programming Mode, you cannot scan normal barcodes
and the scanner will not send data to the host.
A Programming Kit for the
HS1250 is available from PSC or your
dealer or distributor. Ask for part number R44-1340.

R44-1430 5
CONTROLS & INDICATORS
The descriptions on the following pages detail the function of the
controls and indicators for the HS1250. Note that two of these items, the
speaker and volume switch, are located beneath the scanner's top cover.
VOLUME SWITCH
While the scanner is in Normal Mode and the green lamp is on dim,
you can easily change the volume on the HS1250 scanner by pressing
the switch. The scanner has three volume settings available. When
you press the switch, the scanner sounds a tone three times at the
new volume setting. Each time you press the switch, the scanner
sounds the next highest volume until it reaches the highest volume.
After reaching the highest volume, pressing the switch again will
return the volume to the lowest level.
When the scanner is turned off, the volume setting you selected using
the switch will be lost. To change the volume permanently, use the
Volume Selection labels in the Programming Kit (R44-1340).

INDICATORS
INDICATOR LAMP
The indicator lamp has six active modes; off, on dim, flash once,
flashing continually once per second, flashing continually twice per
second and repeating a series of flashes.
Off indicates that either there is no power to the scanner or
the scanner is not operational.
On dim shows that the scanner is on and ready for operation.
This is the normal operating condition.
Flashes once brightly when the scanner has read a barcode
label. This is accompanied by a good read tone from the
speaker unless the speaker has been turned off using
programming labels.
Flashing once per second indicates the scanner has automati-
cally shutdown due to a prolonged period of inactivity.
This condition is referred to as "Sleep Mode" which
extends the life of scanner components by removing
power from the laser diode and motor when the scanner
is not in use. The length of time that the scanner waits
before going into Sleep Mode can be changed using the
programming labels contained in the HS1250/VS1200
Programming Kit (P/N R44-1340).
Flashing twice a second indicates that the scanner is in
Programming Mode. The scanner will not read regular
barcode labels or send data to the host when in this
mode.
Flashes repeatedly accompanied by a repeated series of tones
indicates a scanner failure has occurred.

R44-1430 7
SPEAKER
The speaker produces an audible indication of scanner operation. It
sounds a normal tone, an alternate tone, or an error tone (a repeating
series of tones).
NORMAL TONE
The normal tone sounds when a barcode label is recognized, its
content is decoded and the data is transmitted to the host.
ALTERNATE TONE
The alternate tone has a lower pitch than the normal tone. It is
sounded in four different situations:
• In Normal Mode when the barcode has been read but the
scanner is not programmed to transmit that symbology to
the host.
• In Normal Mode when the
HS1250 cannot successfully decode
a barcode label.
• When in Programming Mode, any programming label that
your scanner cannot use (e.g. Baud Rate for any interface
other than RS-232) is rejected and the alternate tone is
sounded.
ERROR TONE
The error tone alerts the operator of possible system or component
failure and only sounds when a problem is detected.
Number of Tones Failed Components
1 Digital Board
2 VLD (Visible Laser Diode) Module
3 Motor
4 Digital Board
7 VLD (End of life)

CONNECTORS
Three cable connections are located on the scanner as shown below, with
the DC power and Handheld connections in a niche near the serial number
label and the Interface connection in a recessed area of an adjacent side of
the scanner.
INTERFACE CONNECTOR
This connector provides the link between the scanner and the host. It
transmits label data and communication signals between the scanner and
the host.
UNDECODED HANDHELD CONNECTOR
The HS1250 model has a port that allows you to connect an undecoded
(HHLC) scanner. Connecting a handheld scanner to this port allows you to
scan heavy or large items without removing them from the shopping cart.

R44-1430 9
D.C. POWER CONNECTOR
The DC power connector is for attaching the AC/DC power supply to
the scanner. This connector supplies +12VDC, -12VDC and +5VDC to
the scanner.
NOTE
Use ONLY approved AC/DC power supplies
ordered from PSC.
ADDITIONAL FEATURE
MOTION SENSOR
The scanner includes a motion sensor that detects activity in front of
the scan window. Waving your hand or merchandise in front of the
window wakes the scanner up when it is in Sleep Mode. In certain
low level lighting conditions it may be necessary to press the volume
switch to wake-up the scanner. Simply remove the top cover by
using a coin in the coin slot to loosen and lift it, then press the
volume switch to wake the scanner up.

UNPACKING
Before you open the HS1250 shipping carton, inspect the carton for
damage. If the carton is torn or crushed, carefully inspect the con-
tents to ensure that no damage has occurred. Notify your carrier
immediately if you think that there has been any damage to the
contents.
When you open the shipping carton, you should find:
• User's Guide (in your hand)
• HS1250 scanner
• AC/DC Power Supply
• IEC power cord
• Interface cable (if ordered)
If anything is missing or the wrong power cord or interface cable has
been included with your scanner, contact your dealer, distributor or
call your local PSC office. In the U.S. and Canada call PSC Customer
Support Services at [phone]. Otherwise, refer to the list on
the back cover for the subsidiary most convenient to you.

R44-1430 11
VERIFYING SCANNER OPERATION
Prior to installation, we recommend that you connect the scanner and
power supply to AC power to ensure that the scanner is fully
functional.
1. Plug the DC power connector from the AC/DC power
supply into the scanner.
2. Connect the IEC end of the AC power cord into the
AC/DC power supply.
3. Plug the AC power cord into an AC power outlet.
The scanner should emit a tone
indicating that it has passed the Power-
Up Self-Test routine, and the green
lamp will light continuously indicating
that the scanner is ready for operation.
Since the scanner is not connected to a
host terminal, it may only read one or
two labels before it must be reset.
This is normal because some terminal
interfaces require the scanner to store
label data until the POS terminal
signals that it is ready to receive the
data.
If the scanner powers-up, but the
green lamp begins flashing and the
speaker repeats a series of tones, go to
the section titled, Problem Isolation.

POWER-UPPROCEDURE
The system power-up procedure may vary depending on the require-
ments of your Point-of-Sale (POS) system. It is always a good idea to
power-down (switch off) all equipment prior to connecting cables. Check
with your system supervisor and/or refer to the terminal operator's
manual for proper power-down and power-up procedures for your
system.
Before beginning this procedure, disconnect power from the scanner (if
connected).
1. Power-down your terminal.
2. Connect the scanner interface cable to the POS terminal.
3. Connect the IEC power cord to the AC/DC Power
Supply and then to an AC outlet. It is recommended
that the IEC power cord of the AC/DC power supply
be connected to the same AC outlet as used by the POS
terminal.
4. Power-up the terminal.
5. Power-up the scanner.
6. Verify that data is being properly communicated
between the scanner and your POS terminal by scan-
ning a few items.
You have completed the scanner installation and power-up procedures. If
problems occur, follow the procedures titled Problem Isolation on the
next page.
If you want to modify the scanner's interface parameters or change the
user interface (e.g. volume), order the HS1250/VS1200 Programming Kit
