Description
Hewlett-Packard's Bar Code
Decoder ICs offer flexible bar
code decoding capability that is
designed to give OEMs the ability
to address a growing number of
industry segments and applica-
tions. Flexibility is made possible
through sophisticated firmware
which allows the ICs to accept
data from a wide variety of
scanners and to automatically
recognize and decode the most
popular bar code symbologies.
User implementation of the
decoder ICs is easy since it
requires only a few supporting
components and provides a
standard I/O interface.
Manufacturers of data collection
terminals, point of sale terminals,
keyboards, weighing scales,
medical equipment, test instru-
mentation, material handling
equipment, and other systems
having data collection needs are
finding a growing demand for bar
code reading capability in their
products. The HBCR-2210 series
decode ICs make it easy to add
this capability without the need to

invest in the development of bar
code decoding software.
The bar code decoder ICs are
compatible with most hand held
scanners and some medium
speed machine mounted laser
heads. The HBCR-2210 series is
compatible with fixed beam non-
contact scanners, digital wands,
and slot readers. In addition, the
decoder is optimized for use with
the Symbol Technologies moving
beam laser scanners, but is also
compatible with many other
moving beam non-contact laser
scanners with a similar interface
protocol.
The HBCR-2210 series decoder
ICs are excellent decoding solu
4-48
tions for a number of stationary
scanning applications found in
automated systems. The scan rate
for moving beam applications
should be similar to the scan
rates for hand held laser scanners
(35 to 45 scans per second). The
scan speed for fixed beam
applications should be similar to
the scan speeds typical of wands
and slot readers. For moving
beam applications, it is necessary
for the scanner to utilize the three
laser control lines.
The HBCR-2210 series decodes
the most popular bar code sym-
bologies now in use in applica-
tions in the industrial, retail,
government and medical markets:
Code 39 (Standard or
Extended)
Interleaved 2 of 5
UPC A, E
EAN/JAN 8, 13
Codabar
Code 128
Code 11
MSI Code
When more than one symbology
is enabled, the bar code being
scanned will automatically be
recognized and decoded, except
for Standard versus Extended
Code 39, which are mutually
exclusive. Bi-directional scanning
is allowed for all bar codes
except UPC/EAN/JAN with sup-
plemental digits, which must be
scanned with the supplemental
digits last.
The I/O for the decode IC is full
duplex, 7 bit ASCII. Both serial
and parallel interfacing are
available. The serial interface can
be converted to an RS232C
interface or connected directly to
another microprocessor for data
processing. The parallel interface
can be connected to a 74HC646
octal bus transceiver chip (or an
equivalent part). Feedback to the
operator is accomplished by
signals for an LED and a beeper.
In addition, there are many
programmable functions that
cover such items as code
selection, good read beep tone,
Header and Trailer buffers, laser
scanning control, beeper tone,
etc. See Table 2 for a complete
list.
Performance Features
Bar Codes Supported
Code 39 is an alphanumeric code,
while Extended Code 39 encodes
the full 128 ASCII character set
by pairing Code 39 characters.
Both can be read bi-directionally
with message lengths of up to 32
characters. An optional checksum
character can be used with these
codes, and the ICs can be config-
ured to verify this character prior
to data transmission.
Interleaved 2 of 5 code, a com-
pact numeric only bar code, can
also be read bi-directionally with
message lengths from 4 to 32
characters. To enhance data
accuracy, optional checksum
character verification and/or
message length checking can be
enabled.
The following versions of UPC,
EAN and JAN bar codes can be
read bi-directionally: UPC-A,
UPC-E, EAN-8, EAN-13, JAN-8,
and JAN-13. All versions can be
enabled simultaneously or
decoding can be restricted to
only the UPC codes. UPC, EAN,
and JAN codes printed with
complementary two or five digit
supplemental encodations can be
read in two different ways. If the
codes are enabled without the
supplemental encodations, then
only the main part of symbols
printed with supplemental
encodations will be read. If the
reading of supplemental
encodations is enabled, then only
symbols with these supplements
will be read. When supplemental
encodations are enabled, the bar
code symbols must be read in a
direction which results in the
supplements being scanned last.
Codabar, a numeric only bar code
with special characters, can be
read bi-directionally for message
lengths up to 32 characters. The
decode IC can be configured to
transmit or suppress the Codabar
start/stop characters.
Code 128, a full ASCII
symbology, can be scanned bi-
directionally with message
lengths of up to 32 characters.
Code 11 is a numeric, high
density code with one special
character, the hyphen (-).
Verification of one or two check
characters must be enabled, and
the check character(s) are always
transmitted. This code can be
scanned bi-directionally.
MSI Code is a numeric, continu-
ous code, with message lengths
up to 32 characters. The check
digit, a modulo 10 checksum, is
always verified and transmitted.
This code can be scanned bi-
directionally.
Scanner Input
The HBCR-2210 decode IC is
designed to accept data from
hand held digital scanners or slot
readers with the following logic
state: black = high, white = low.
The same decode IC also accepts
4-49
data from hand held laser
scanners with the opposite logic
states: black = low, white =
high. The scanner type pin (SCT)
on the HBCR-2210 series must be
driven prior to power up or hard
reset to identify the type of
scanner connected.
In the HBCR-2210 series ICs, the
automatic laser shutoff feature
delay time is adjustable as a con-
figuration option. Applications
which require increased accuracy
may need the redundancy check
feature.
Scanner input can be disabled by
software command. This allows
an application program to control
when an operator can enter data,
preventing inadvertent data entry.
It also allows the program to
verify each scan before enabling
subsequent scans. The HBCR-
2210 series also offers two Single
Read Modes which allow the
application program to stop bar
code data entry until a "Next
Read" command is received,
allowing the host computer to
process data transmissions before
enabling subsequent reads.
Configuration Control and
Non-volatile Storage
Configuration of the decoder IC
is done by any of three methods.
A minimal subset of key options
can be "hardwired" controlled
by electrically strapping specified
pins on the decoder IC itself.
Which pins affect configuration
depends on the selection of serial
or parallel interface. Alternatively,
ASCII characters in the form of
HP Escape Sequences (a format
common to HP decoder ICs) can
be sent to the serial or parallel
I/O port; these commands can be
used to control all configurable
options. A third method is optical
configuration, which makes use
of special bar code menus sup-
plied by HP. Menu labels can be
created to modify any configur-
able options. A summary of the
decoder IC features and
applicable configuration methods
for each is presented in Tables 2
and 3.
Once configuration has been set,
it can be stored in an optional
non-volatile memory, if included
in the decoder circuit. When the
EEP pin is tied high, the decoder
IC drives I/O lines compatible
with the widely available 9346/
93C46 family of serial EEPROMS.
The configuration is thereby
saved during power down of the
system and automatically
reloaded at power up. Escape
sequence commands allow
explicit storage and recall of
configuration settings. When
using optical configuration,
storage is automatic. If the EEP
pin is tied low, the EEPROM is
not used, so only hardwired
configuration options are saved
through powerdown; all others
are set to default values at
powerup. Table 2 shows default
values of all features.
Data Communications
The serial port supports a wide
range of baud rates, parities, and
stop bits as described in Table 2.
Software control of data trans-
mission can be accomplished
with a standard Xon/Xoff (DC1/
DC3) handshake. The decode IC
also supports an RTS/CTS
hardware handshake.
The parallel port data has config-
urable parity. When the SMD pin
is tied low, several pins pertain-
ing to the serial port change
function to control a parallel port
instead. Pins 1 through 5 on DIP
packages assume the function of
handshake lines for the parallel
port. The port itself is an external
'646 family octal bus transceiver.
Processor pins 10 and 11 (TXD
and RXD in serial mode) now
control the transceiver chip along
with pins 16 and 17, RD and WR.
Alternative circuits using SSI
latch chips can be substituted for
the '646 implementation to
customize the function of the
parallel port to a particular bus
configuration.
Feedback Features
Both audio and visual feedback
are possible with the HBCR-2210
series. In both cases, the outputs
from the ICs should be buffered
before driving the actual feed-
back transducer. An LED or
beeper connected to the decoder
IC can be controlled directly by
the IC, with signals generated by
successful decodes, or can be
controlled by the host system. In
addition, the tone of the beeper
can be configured to be one of 16
different frequencies, or can be
silenced.
Power Requirements
The decoder IC operates from a
+5 volt DC power supply. The
maximum current draw is 18 mA.
The maximum power supply
ripple voltage should be less than
100 mV, peak-to-peak.
Handling
Precautions
The decoder ICs are extremely
sensitive to electrostatic
discharge (ESD). It is important
that proper anti-static procedures
be observed when handling the
ICs. The package should not be

PLCC Drying
Whenever Vapor Phase or Infra-
red Reflow Technologies are used
to mount the PLCC packages,
there is a possibility that
previously absorbed moisture,
heated very rapidly to the reflow
temperatures, may cause the
package to crack from the
internal stresses. There is a
reliability concern that moisture
may then enter the package over
a period of time, and metal
corrosion may take place,
degrading the IC performance.
To reduce the amount of
absorbed moisture and prevent
cracking, all of the PLCC ICs
should undergo one of the

following baking cycles. The
parts must then be mounted
within 48 hours.
If the parts are not mounted with-
in 48 hours, they must be re-
baked.
The total number of baking cycles
must not exceed two. If the ICs
are baked more than twice,
Hewlett-Packard cannot guaran-
tee the performance and
reliability of the parts.
Neither bake cycle can be per-
formed in the standard shipping
tubes. The ICs must be baked in
an ESD safe, mechanically stable
container, such as an aluminum
tube or pan.
