GUIDE
USE THIS PAGE
As a general overview of the programming menu. The programming menu consists of two basic components as
shown below.
MENU PAGE FACING (Not Shown)
MENU PAGE
BAR CODE DATA CHART
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.
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.
USE THIS PAGE – A summary of the programming options (parameters) of each 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.
ENTER – Each menu page has its own unique ENTER bar code; scan this bar code to activate desired menu page.
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.
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.

BEEPER
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
Whenenabled,thereader willdoublebeep eachtimethe systemisreset. 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
Whenenabled,thereader willclickonce aftereachrow ofaCode 16KorCode49stacked
barcode has been read. When disabled, thebeeper will not sound afterscanning rows of
Code 16K or Code 49 stacked bar code. Default = disabled (“No”).
PDF417: Ticking Indicates Scanning Progress
Whenenabled,thereader willemita tickingsoundas it scansaPDF417 symbol. Therate
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 One beep signals a successful barcode read.
Double Beep 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
programming menu pages).
Triple Beep Three quick beeps in succession indicate an error condition, as when an
illegalmenucodeisscanned,orwhentheserialinputbufferoverflows. 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.
Click A“Click” hasthe samepitch as a beep, buthas amuch shorterduration. 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, sincethey
have been optimized to read stacked codes.

Baud Rate
Thisprogramming selection sets the baudratefrom600 bits per second to38,400bitsper
second. Programmingbaudratecausesthedatatobesentatthespecifiedrate. Default=
9600 bits per second.

Character Format
This programming selection allows you to set the character format for number of data and
paritybits. PDFcapableproductssupportsevenoreightbitsofdataandzerooroneparity
bit per character. The number of start and stop bits is fixed at one each. If an application
requiresonlyASCIIcharacters0through127decimal(text,digits,andpunctuation),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.
Data Flow Control
Note: PDF417 data is checked for accuracy before it is transmitted. This doesn’t
guaranteethat errors won’tbe introduced during datacommunication. A parity bit maybe
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.
Flow control may be necessary to handle the larger PDF417 messages. The PDF417
readerwill 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.
Forexample: supposethereceiverstorestransmittedcharactersina512–bytebuffer,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
processesthe message,space becomesavailablein the512–bytebufferand thereceiver
can tell the reader to START 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
Thisoptionwillusetwowiresconnectedtoboththereaderandthereceiver. Thereaderwill
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. (IfthereaderhasnomessagestosenditwillgroundtheRTSline.) 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
accepta messagefrom thereader itshould raise(the voltageon) theClearTo 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
19decimal)tothereader. Whenthereceiverwantstoresumetransmission,itwillsendthe
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.

Manual Trigger Enable
Note:ManualTriggermodeisnotavailableinhand–heldscannershavingnotriggerswitch
(such as the 3000–0XC).
Inautotrigger mode, the reader scans continuously. Itdoesnot,however,output decoded
messages continuously. Internal logic determines when to output a decoded message.
Thisdecision is based on several factors, includingthestateofTRIGGER ON/OFF. Inthe
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.
Thereader’snewautotriggerlogicisaggressive,resultinginfastreads. Itis
not necessary
to TRIGGER OFF in order to read a
new code, but in order to reread the same code, one
needs to TRIGGER OFF for about a quarter of a second.
Inmanualtriggermode, aTRIGGER ONisrequiredtoactivate scanningand decoding. In
the context of manual trigger mode, TRIGGER ON/OFF are defined as:
TRIGGER ON – (A) The trigger switch is pressed
or (B) The serial TRIGGER ON
command (ASCII 18 decimal) is sent to the reader.
TRIGGER OFF – (A) The trigger switch is released
or (B) The serial TRIGGER OFF
command (ASCII 20 decimal) is sent to the reader.
In manual trigger mode it is necessary to TRIGGER OFF following a successful decode
beforeanother codecanbe read. The scanning stops immediatelyfollowinga successful
decode,butthereaderisnotTRIGGEREDOFFuntiloneoftheconditionsabovehasbeen
satisfied.
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)untilthetriggerispulled. Refertothescanner’sTechnicalManualforspecifics.
Generally, a TRIGGER ON causes the reader to begin decoding, and a TRIGGER OFF
haltsdecoding. ThemeaningofTRIGGERONandTRIGGEROFFdependsonthetrigger
mode.
Note: If the scanner is triggered serially, it isn’t necessary to send the TRIGGER OFF
command.

Preamble PostambleBar Code Message
Characters for the preamble and postamble are selected by their hexadecimal ASCII
value, up to 8 characters each. In addition, special characters are available for code
identification and for error detection. Programming preamble/postambles is flexible,
allowing creative framing possibilities.
These preamble/postambles apply to all messages regardless of the symbology, and
cannot be assigned for a specific symbology. The special characters for Code ID
will
change to indicate the decoded symbology.
Preamble/Postamble Examples:
1. The postamble defaults to a carriage return plus line feed:

If this option is enabled, any partial PDF417 scan will be
cleared from memory upon a TRIGGER OFF. Normally
PDFscansaresavedinmemoryuntileitheraDECODEor
a new PDF417 label is scanned. It is not always possible
for the reader to know when a new label is introduced.
If this option is enabled, the reader sends out a message
(ASCII decimal 23) to notify the host system that a
successfulPDF417decodeiscertain;nomorescanningis
required.
For Example: in a machine–mount system, a host
computer moves a PDF417 label back and forth in front of
the PDF Capable reader until the ASCII decimal 23 is
received. At that point scanning is completed, and the
decoded message will follow.
The PDF Capable reader must temporarily halt scanning
inorderto performPDF417decoding. A refinedalgorithm
automaticallypredictswhenenough informationhasbeen
scanned to insure a successful decode. If the scanned
data contains many errors, though, decoding cannot
succeed and more scanning is required.
In a machine–mount system with a predetermined scan
cycle, it may be an advantage to use
Trigger–Off

. Whenthisoption isenabledthe reader willnot

the predetermined scanning time, the reader is sure to be

Using the Serial Menu

SERIAL MENU SCANTEAM 3000/PDF Programming Menu
The serial menu may be used any time in place of the bar code menuing. The
serial menu is particularly useful for programming PDF capable machine–mount
readers that don’t have a hardware trigger.
Every programming menu code can be replaced by a two–character serial
command. Aserial device programs the readerbysending the proper sequence
of serial commands. Use the menu pages to select the programming variables
your application requires.
For every menu code, the equivalent two–character serial command (and its
correspondingASCIIdecimalvalue)aregivenintheSERIALMENUCHARTSon
the following pages.
Example 1
For instance, if you want PDF417 enabled and all other bar code symbologies
disabled, use the CODES (STACKED) menu page. The correct sequence of
serial commands would be:
The above serial commands correspond to the selections and variables on the
programming menu page:
F <Ctrl–X> T <Ctrl–Y> 0 <Ctrl–Y> K <Ctrl–Y> 0 <Ctrl–Y> <SPC> <Ctrl–Y>
•ENTER code for that menu page
•“Disable All Codes” selection (Roman Numeral X)
•“Yes” (Digit 0) to disable all codes
•PDF417 selection (Roman Numeral I)
•“Yes” (Digit 0) to enable PDF417 decoding
•“EXIT” code for that menu page.
Example 2
If you wish to enable ticking to show PDF417 scanning progress, use the
BEEPER menu page. The correct sequence of serial commands would be:
The above serial commands correspond to the selections and variables on the
programming menu page:
A <Ctrl–X> O <Ctrl–Y> 0 <Ctrl–Y> <SPC> <Ctrl–Y>
•ENTER code for that menu page
•“Ticking Indicates Scanning Progress
(PDF417) ” selection (Roman Numeral V)
•“Yes” (Digit 0) to enable this selection
•“EXIT” code for that menu page.
Special Notes:
TakecarenottoconfusetheletterOandthenumber0. NotealsothattheDEFAULTcodeis
representedbyaperiod(.)followedby<Ctrl–Y>. ASCII(decimal)valuesareincludedonthe
SERIAL MENU CHARTS (below the corresponding serial command).
RS–232 parameter changes are immediately effected. The connected host serial device
must also change to the programmed selections accordingly. After changing baud rate it
may be necessary to wait a short amount of time for the serial port to stabilize. For this
reason bar code menuing is suggested for changing RS–232 parameters.
In manual trigger mode, two serial commands may be used to turn the trigger
on/off. The commands are:
ASCII 18 (decimal) Ctrl–R Trigger ON
ASCII 20 (decimal) Ctrl–T Trigger OFF
For PDF417, the notify–when–certain character is:
ASCII 23 (decimal) Ctrl–W Notify–When–Certain

In combination with the adjoining menu pages to program the 3000/PDF by sending serial commands from the host.
