Description
Hewlett-Packard’s Industrial
Digital Slot Reader is designed to
provide excellent scanning
performance on a wide variety of
bar coded cards and badges. It
contains a unique optical/
electrical system that integrates
over a large vertical area of the
bar/space pattern, providing a
greatly improved first read rate
even on poorly printed bar codes.
The HBCS-7100 Series uses an
infrared (880 nm) light with 0.19
mm (0.0075 in.) resolution.
The extra large depth of field
allows the slot reader to have a
slot width of 3.2 mm (0.125 in.),
thus making it possible to read
even thickly laminated cards and
badges. When used as a stand
alone optics module, the
maximum depth of field is
dependent upon resolution.
The optics and electronics are
housed in a rugged metal case.
The case is fully gasketed and
sealed, making it suitable for use
in outdoor or wet environments.
The black epoxy coating adds a
durable, finished look to the
Digital Slot Reader. When
installed using the rear screw
holes, the units become tamper
proof, making an excellent choice
for security access control.
The optical system is centered in
the slot track, allowing the user to
easily scan from either direction.
The wide slot width makes it easy
to insert and slide the cards. The
optical system is covered with a
recessed window to prevent
contamination and reduce the
wear on the cards.
The standard slot reader comes
with the optics module mounted
on a base plate with an opposite
rail and 122 cm (48 in.) straight
cord. Two standard connectors
are available: a male 5 pin, 240°,
locking DIN (HBCS-7100); or a
female, 9 pin D-sub squeeze to
release, (HBCS-7108).
The optics module (HBCS-7150)
is available which can be
integrated into other equipment
or used as a stand alone sensor
assembly.

scanning is faster and more
accurate than key entry and
provides far greater throughput.
In addition, bar code scanning
typically has a higher first read
rate and greater data accuracy
than optical character recognition. When compared to magnetic
stripe encoding, bar code offers
significant advantages in flexibility of media, symbol placement
and immunity to electromagnetic
fields.
Hewlett-Packard’s Industrial
Digital Slot Reader is designed for
applications where high first read
rate and durability are important
factors. The epoxy coated metal
case with its tamper proof
mounting system, makes these
slot readers ideal choices for
security access control, time and
attendance recording and other
bar coded badge and card reading
applications.
Electrical Operation
The HBCS-71XX family of digital
slot readers consists of a precision optical system, an analog
amplifier, a digitizing circuit, and
an output transistor. These
elements provide a TTL compatible output from a single 4.5 V to
5.5 V DC power supply. The open
collector transistor requires a
pull-up resistor for proper
operation.
A non-reflecting black bar results
in a logic high (1) level output,
while a reflecting white space will
cause a logic low (0) level output.
After power up, the slot reader
will be fully operational after
approximately 6 seconds. During
operation, the slot reader will
4-76
assume a logic low state after a
short period (typically 1 second)
if no bar code is scanned. This
feature allows multiple scanners
(slot readers and wands) to be
connected together with a simple
OR gate.
The slot reader connector provides a shield which is connected
to signal ground. The shield is
connected either to the metal
housing of the 5 pin DIN
connector, or to pin 8 of the 9 pin
D-sub connector. A good
connection to earth ground is
recommended.
The maximum recommended
cable length is 7.6 m (25 ft.).
WARNING:
OBSERVING THE INFRARED
LIGHT SOURCE IN THE HBCS7150 AT CLOSE DISTANCES
FOR PROLONGED PERIODS OF
TIME MAY CAUSE INJURY TO
THE EYE. When mounted with
the rail in place, the infrared
output flux is radiologically safe.
With the rail removed, precautions should be taken to avoid
prolonged visual observation.
Mounting Considerations
Slot Reader
The slot reader (HBCS-7100/
7108) is designed to be virtually
tamper proof when mounted
using the two rear mounting
holes. In this case, the cable must
be routed from the rear of the slot
reader through the mounting
surface (wall, door, etc.).
When mounting the slot reader,
the cable may be routed through
the mounting surface (see above),
or it may be routed along grooves
in the base and exit the side of the
slot reader at any of four points.
This allows flexibility in the
mounting orientation.
Optics Module
The optics/electronics module
(HBCS-7150) is designed for
applications which require a
different slot width, integration
into a larger housing, or a fixed
beam stationary scanner. When
using the optics module, the
operating distance from the front
surface of the module to the
symbol will vary depending on the
symbol resolution. Figure 1 shows
the relationship between operating range and minimum symbol
resolution for a typical optics
module.
This relationship was applied in
the design of the slot reader,
where a slot width of 3.2 mm
(0.125 in.) insures excellent
performance reading bar code
symbols which have a nominal
resolution of 0.19 mm (0.0075
in.) and include normal printing
errors.
