Description
The Hewlett-Packard Single Chip
Bar Code Decoder IC offers
flexible bar code decoding that is
designed to give OEMs the ability
to address a growing number of
industry segments and applica-
tions. Flexibility is made possible
through firmware that allows the
IC to automatically recognize and
decode the most popular bar
code symbologies. User imple-
mentation is easy since only a few
supporting components are
required.
The HBCR-1610 series decodes
the most popular bar code
symbologies used in applications
in government, retail, industrial
and medical markets. The IC
automatically discriminates and
decodes the following
symbologies:
Code 39 (Standard or
Extended)
Interleaved 2 of 5
UPC A, E0, E1
EAN/JAN 8, 13
Codabar
Code 128
All bar codes may be scanned
bidirectionally except for UPC/
EAN/JAN bar codes with supple-
mental digits, which must be
scanned so that the supplemental
digits are scanned last.
Scanner Input
The HBCR-1610 decode ICs are
designed to accept input from
hand held digital scanners and
slot readers. The maximum scan
speed is 30 ips (73 cm/s).
Data Communications
The serial port supports a variety
of baud rates, parity, and stop
bits as described in Table 5. The
IC has a "Single Read Mode"
which allows the application
program to stop data input until a
"Next Read" command has been
received. This allows the host
computer to process data
transmissions before enabling
subsequent reads. Control of data
transmission is available using
the standard XON/XOFF (
D1/ D3
)
handshake.
The parallel port is accomplished
via an external 74HCT646 (octal
bus transceiver) or two
74HCT574s (octal latches).
There are handshake lines for
both data and commands.
Feedback Features
Both audible and visual feedback
are possible with the HBCR-1610
series. In both cases, the
feedback outputs from the IC
should be buffered before driving
the transducer. An LED or beeper
connected to the IC is either
controlled directly by the IC, with
signals generated by successful
decodes, or controlled by the
host system. The tone of the
beeper can be configured to one
of 16 tones, or can be silenced.

Power Requirements
The decoder IC is operated from
a +5 volt DC power supply. The
maximum current draw is 24 mA.
The maximum power supply
ripple voltage should be less than
100 mV, peak-to-peak.
Idle Mode
The IC automatically reduces
power consumption whenever
there is no scanning or decoding
activity, or when there is no
activity on the I/O port. See
Table 4.
Manual
The HBCR-1610 Series Users
Manual (HBCR-1697) covers the
following topics:
Specifications and Timing
Diagrams
Pin Definitions and Schematics
General Scanning Tips
Configuration and Operation
Escape Sequence Programming
Data Output Formats
Sample Bar Codes
I/O and Pacing Characteristics
IC Configuration
The default configuration is set
when the IC powers up or when a
Hard Reset command is received.
Default configuration of many of
the options is dependent on the
logic states of IC pins, as shown
in Table 5. A complete descrip-
tion of the pins and all possible
configurations is in the Users
Manual. More complete and
flexible configuration is achieved
using escape sequence
commands.
There are two pins that cause
significant changes in the IC
operation.

FRQ Pin
The
FRQ
pin is used to tell the IC
what frequency oscillator is
attached to the IC. Using the
higher frequency allows greater
maximum scan speeds, but
causes the IC to draw slightly
more supply current. If the state
of the
FRQ
pin does not match
the actual oscillator, beeper
tones, LED flash length, parallel
port timing, and serial port baud
rates are adversely affected.

Escape Sequences
The following set of escape
sequences is used to control the
IC and change its default configu-
ration. Note that all configuration
changes will be lost after a Hard
Reset, or after power up. Detailed
information on how to formulate
and use escape sequences is
given in the Users Manual.
