MENU PAGE

Each menu page represents one section of the programming menu. Use individual menu pages in combination with
the bar code chart on the back page foldout to program the decoder.

USE THIS PAGE – A summary of the programming options (parameters) of each menu page.
ENTER – Each menu page has its own unique ENTER bar code; scan this bar code to activate desired menu page.
DEFAULT – The DEFAULT bar code allows the user to independently default menu pages to asterisked (*) values

without affecting, in any way, the rest of the programming menu. Default values can be easily selected from the
desired menu pages by scanning the bar code sequence ENTER, DEFAULT, EXIT. Individual defaults for a specific
selection can be made by scanning ENTER, ROMAN NUMERAL, DEFAULT, EXIT.

ESCAPE – Use this bar code to cancel current programming sequence. All parameters remain as they were. Scan
ESCAPE to abort changes and exit from programming mode.

EXIT – Scanning this bar code ends programming selection. Go from one menu page to another by scanning a new
ENTER code (no need to scan EXIT between pages). Scan EXIT to save changes and end programming sequence.

SELECTIONS/VARIABLES – Lists all of the options available on each menu page. Following each option are
symbols in shaded areas. These symbols correspond to bar codes on the adjoining bar code chart.

NOTES – are provided to call out any unusual situations and/or refer you to necessary information or examples
elsewhere in the menu or manual.

Programming Note: Programming changes are in effect as soon as you make them! For example: changes to the
beeper volume can be heard instantly. Likewise, changes to the baud rate parameters occur as soon as the “ENTER
RS–232,” Roman Numeral “I,” and number (“0–6”) sequence has been scanned. EXIT will save the changes; ESCAPE
will restore the original settings. Take care that programming parameters match your terminal settings.

MENU PAGE FACING (Not Shown)

The page facing the menu is often used to supplement or clarify the material presented on the front of each menu
page. The information and examples found here are specific to the individual menu page and contain, in some cases,
charts and diagrams that must be used in order to determine the correct programming sequence.

BAR CODE DATA CHART

The bar codes on this chart are assigned to a ROMAN NUMERAL, LETTER, DIGIT, OR YES/NO symbol. These bar
codes correspond to the symbols in shaded areas on the menu pages and are scanned in various combinations to
enter programming sequences to the decoder. Bar codes on this page are meaningless unless an ENTER bar code
from one of the menu pages is first scanned. When an ENTER bar code is scanned, the bar code chart becomes
specific to that menu page and remains so until the EXIT bar code is scanned or another menu page is selected.

BEEPER

SCANTEAM 3000/PDF Information/Examples

Volume

This programming selection provides control of the reader’s beeper volume. The beeper
volume may be set from low to high in four increments. Default = “2,” medium–high.

Beep on Power Up

When enabled, the reader will double beep each time the system is reset. When disabled,
the beeper will not sound whenever the system is reset. Default = enabled (“Yes”).

Beep on Good Read

When enabled, the reader will beep once following a successful decode. When disabled,
the beeper will not sound following the decode. Default = enabled (“Yes”).

Code 16K, Code 49: Click on Row Read

When enabled, the reader will click once after each row of a Code 16K or Code 49 stacked
bar code has been read. When disabled, the beeper will not sound after scanning rows of
Code 16K or Code 49 stacked bar code. Default = disabled (“No”).

PDF417: Ticking Indicates Scanning Progress

When enabled, the reader will emit a ticking sound as it scans a PDF417 symbol. The rate
of ticking is proportional to the rate of data collection. When disabled, the beeper will not
sound while scanning a PDF417 symbol. Default = disabled (“No”).

PDF417: Humming Indicates Decoder Is Busy

When enabled, the reader will emit a humming sound while it is decoding a PDF417
symbol. When disabled, the beeper will not sound while decoding a PDF417 symbol.
Default = enabled (“Yes”).

What the Beeper is Telling you:

As audible feedback, the PDF Capable reader provides six different beeps:

single beep, double beep, triple beep, click, tick, and hum.

Single Beep
Double Beep

Triple Beep

Click

Tick

Hum

One beep signals a successful barcode read.
Two beeps in succession indicate either:

• a hardware reset (as when the unit is first powered on)

• ENTER/EXIT/ESCAPE programming mode (when using the

Three quick beeps in succession indicate an error condition, as when an
illegal menu code is scanned, or when the serial input buffer overflows. Every
character sent to the PDF Capable reader is stored in a buffer. If the
characters arrive faster than the reader can process them, it is possible
(though rare) that the input buffer will completely fill up, and an overflow
occurs. See Technical Manual for more details.
A “Click” has the same pitch as a beep, but has a much shorter duration. The
click signals a successful row read for stacked codes 16K and 49. This
provides useful feedback when the codes are scanned using a wand. Such
feedback may not be as useful when using PDF Capable readers, since they
have been optimized to read stacked codes.

The “Tick” has the shortest duration, and no perceivable pitch. It is used to
indicate scanning progress while reading PDF417. A tick is initiated for every
32 PDF417 codewords read. A high rate of ticking corresponds to a high rate
of data collection, thus good printing and good scanning technique are
indicated by a high ticking rate.

Refer to the PDF Technical manual for printing/scanning suggestions. In general,
keep the scan line of the reader aligned with the rows of the symbol. Printing smaller
X–dimension and larger Y–dimension (row height) aids scanning ability.

The “Hum” is a steady tone with a lower pitch and volume than the beep, and a
variable duration. The PDF417 reader can’t scan while decoding PDF417.
When a great deal of error correction is required, the reader may appear to be
“locked up.” Humming indicates that the reader is busy decoding. Use the
ticking option for PDF417 to learn how to scan for optimum performance.
Careful scanning greatly decreases PDF417 decoding time.

RS–232

SCANTEAM 3000/PDF Information/Examples

Baud Rate

This programming selection sets the baud rate from 600 bits per second to 38,400 bits per
second. Programming baud rate causes the data to be sent at the specified rate. Default =
9600 bits per second.

Character Format

This programming selection allows you to set the character format for number of data and
parity bits. PDF capable products support seven or eight bits of data and zero or one parity
bit per character. The number of start and stop bits is fixed at one each. If an application
requires only ASCII characters 0 through 127 decimal (text, digits, and punctuation), select
7 data bits. For applications requiring use of the full ASCII set, select 8 data bits per
character. Default = eight data bits, no parity, and one stop bit.

Note: PDF417 data is checked for accuracy before it is transmitted. This doesn’t
guarantee that errors won’t be introduced during data communication. A parity bit may be
added to each transmitted character as a means of character validation. A checksum
character may also added to the message as a postamble (suffix), for even stronger
security (see Preamble/Postamble menu page). The receiving device must be set up for
precisely the same character format as the reader, to ensure reliable communication.

Data Flow Control

Flow control may be necessary to handle the larger PDF417 messages. The PDF417
reader will normally transmit a message immediately following a successful decode. With
flow control selected, the receiver can enable/disable the reader’s transmitter. Default =
“None,” no data flow control option selected.

For example: suppose the receiver stores transmitted characters in a 512–byte buffer , yet
the PDF417 reader has a 1400–byte message to transmit. The receiver might take 510
characters into its buffer, then tell the reader to STOP transmitting. As the receiver
processes the message, space becomes available in the 512–byte buffer and the receiver
can tell the reader to STAR T transmitting again.

Two methods of flow control have been implemented in the PDF capable products:
RTS/CTS hardware handshaking, and an XON/XOFF protocol.

RTS/CTS Handshaking

This option will use two wires connected to both the reader and the receiver. The reader will
have control of the RTS line, the receiver controls the CTS line.

Whenever the reader has a message to send, it will raise (the voltage on) the Ready To
Send (RTS) line. (If the reader has no messages to send it will ground the RTS line.) When
the receiver wants to suspend transmission it should ground the CTS line. The reader
looks at the state of CTS prior to sending each character. When the receiver is willing to
accept a message from the reader it should raise (the voltage on) the Clear T o Send (CTS)
line. The reader will resume sending messages, continuing where it left off when the CTS
line was grounded.

XON/XOFF Protocol

This option uses only the transmit/receive lines between the reader and the receiver.
When the receiver wants to suspend transmission, it will send the XOFF character (ASCII

19 decimal) to the reader. When the receiver wants to resume transmission, it will send the
XON character (ASCII 17 decimal) to the reader. The reader will resume sending
messages, continuing where it left off when the XOFF character was sent.

TRIGGER

Generally, a TRIGGER ON causes the reader to begin decoding, and a TRIGGER OFF
halts decoding. The meaning of TRIGGER ON and TRIGGER OFF depends on the trigger
mode.

SCANTEAM 3000/PDF Information/Examples

Autotrigger Enable

In autotrigger mode, the reader scans continuously. It does not, however , output decoded
messages continuously. Internal logic determines when to output a decoded message.
This decision is based on several factors, including the state of TRIGGER ON/OFF . In the
context of autotrigger mode, TRIGGER ON/OFF are defined as:

TRIGGER ON – The scanner senses the presence of several black/white elements
(does not yet know if pattern is decodable).

TRIGGER OFF – The scanner senses the lack of black/white elements.

The reader’s new autotrigger logic is aggressive, resulting in fast reads. It is

Manual Trigger Enable

In manual trigger mode, a TRIGGER ON is required to activate scanning and decoding. In
the context of manual trigger mode, TRIGGER ON/OFF are defined as:

TRIGGER ON – (A) The trigger switch is pressed
command (ASCII 18 decimal) is sent to the reader.

TRIGGER OFF – (A) The trigger switch is released
command (ASCII 20 decimal) is sent to the reader.

In manual trigger mode it is necessary to TRIGGER OFF following a successful decode
before another code can be read. The scanning stops immediately following a successful
decode, but the reader is not TRIGGERED OFF until one of the conditions above has been
satisfied.

Note: If the scanner is triggered serially, it isn’t necessary to send the TRIGGER OFF
command.

A power–saving mode is available for hand–held readers having a hardware trigger in
manual trigger mode. All that is required is the proper cable. (Contact your sales

representative or refer to the IPWC Cable Matrix for hand–held CCD
constant/switched–power cable information.) On power–up, the reader senses if the

unit is using the switched–power cable, and goes immediately into a low–power mode.
Only the trigger–sensing circuitry is powered (current draw is  0.23 mA @ 5V for
3000–12C) until the trigger is pulled. Refer to the scanner’s T echnical Manual for specifics.

Note: Manual Trigger mode is not available in hand–held scanners having no trigger switch
(such as the 3000–0XC).
