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.
