RS-232 INTERFACE PROGRAMMING
For your convenience, this guide provides minimal configuration and option
settings for your scanner's RS-232 interface. For more detailed programming
information and features, reference the SP400 Programming Guide (R44-1020) or the
QuickScan 6000/6000 Plus Programming Guide (R44-1540), available from your dealer.
THE QUICKSCAN 6000/6000 PLUS INTERFACE (I/F) CABLE
To disconnect the I/F cable at the scanner, insert a bent paper clip or 0.050" hex
driver into the opening marked CABLE RELEASE as shown in Figure 1, and push
inward. Once the connector latch is released, continue to hold the latch in while
carefully pulling the cable free.
Connect the QuickScan 6000/6000 Plus scanner to your system using ONLY the
proper PSC approved QuickScan 6000/6000 Plus I/F cable.
WARNING
Connection using an unapproved cable can result in
damage to the scanner. QuickScan 6000/6000 Plus
cablescanbeidentifiedbyacableI.D.codeprintedon
a white label, approximately 1” in length, attached to
them.

capability that will automatically select the host-
specific interface type when the cable is attached.
For example, a scanner attached using an RS-232
cable will automatically communicate via RS-232;
when attached using a Keyboard Wedge cable, it
will automatically communicate with a Keyboard
Wedge system.

RETURN TO FACTORY CONFIGURATION
If, during a programming session, you wish to reset the scanner's configuration to
its original factory settings, scan the Return to Factory label below. Use this label
ONLY IF NECESSARY, since it will reset any changes made to this interface
during any previous programming session.
RETURN TO FACTORY

PROGRAMMING MODE
Thescanner must be placedin Programming Mode beforeits configuration can bealtered
usingthebarcodes in this guide. Enter programming mode byscanningtheSET barcode at
thetopofeachprogrammingset. Thescanner'sgreen light will flash continuously, indicating
thescannerisinProgrammingMode.
While in Programming Mode, the scanner will recognize only specially formatted
programming bar code labels like those contained in this guide, and will not decode
bar code labels of any other type. Scan all programming bar code labels needed to set
the scanner's features to the desired settings. The scanner will beep after each bar code
label is scanned, indicating that the setting has been stored in memory. The scanner
will emit a rejection tone if a scanned bar code programming label isn't valid.
To exit Programming Mode and save all changes made during the programming
session, scan the END bar code at the bottom of each programming set. The
scanner will return to normal operation.
Disconnecting power during Programming Mode will cause the scanner to return
to its previous settings.

HANDSHAKING
Review your system documentation to identify system handshaking requirements,
and use these labels to change the setting if required.
CTS/RTS(Flow Control) — is hardware handshaking. The RTS
(Ready to Send) line is activated by the scanner. Only after receiving an
active Clear to Send (CTS) signal from the host is the data sent. The
scanner's RTS line is only active during data transmission.
CTS Scan Control — is also a hardware control. When scan control is
enabled, label transmission is disabled until CTS is asserted and de-
asserted.
XON/XOFF — this is software handshaking that allows the host to
control data transmission. The XON (SEND) and XOFF (STOP) commands
from the host controls the scanner's transmission of bar code data.
NOTE
Hardware/software controls are mutually ex-
clusive. Enableonlyoneofthesefeaturesata
time, as enabling multiple controls can pro-
duce unpredictable results.

RS-232 ACK/NAK OPTIONS (QUICKSCAN 6000 PLUS ONLY)
Several ACK/NAK parameters can be set for your QuickScan 6000 Plus scanner.
Contact your PSC®dealer if the specific ACK/NAK option you wish to set is not
included in this section.
Options for RS-232 ACK/NAK are:
• Disable ACK/NAK
• Enable ACK/NAK for bar code transmission
• Enable ACK/NAK for host command acknowledge
• Enable ACK/NAK for bar code transmission and host command
acknowledge.

INTERCHARACTER DELAY
INTERCHARACTER DELAY
Intercharacter Delay refers to the pause, if any, between each character before it is
sent to the host. This time delay is used to control the flow of data from the
scanner, but it should not be required for most applications.

PREFIX/SUFFIX
SETTING PREFIX AND/OR SUFFIX CHARACTERS (PREAMBLE/POSTAMBLE)
To set the prefix or suffix, identify your specific system requirements for modifica-
tion of the settings, then follow these steps:
1. Look at the ASCII chart on the inside back cover of this manual and
identify the ASCII character and the corresponding Hex Code you
will use as the prefix or suffix.
2. Scan the SET label below.
3. Scan either the SET PREFIX or SET SUFFIX label.
4. Scan the Hex Code for that character.
(e.g. 03, 8F, ...FF)
NOTE
Ifyoumakeamistake,orloseyourplacewhilesettingthisoption,
scan the END label to exit Programming Mode. The scanner will
sound an error tone to indicate that programming was incom-
plete, and the setting will remain as it was before entering
Programming Mode.
5. If setting a single digit, scan the ONE CHARACTER ONLY label
on the second page following.
6. Scan the END label.
You have set the prefix or suffix.

SETTING SYMBOLOGY SPECIFIC LABEL IDENTIFIERS (LABEL I.D.)
Symbology-specific label identifiers comprise one or two ASCII characters that can
precede or follow barcode label data as it is transmitted to the host. The host uses
these characters as a means of distinguishing between symbologies.
Industry standards have been established for symbology-specific label identifiers,
and are listed in the table below. Most scanners will have factory default identifiers
preset to these standards.
UPC-A ------------------------------ 'A' EAN-8 (5 Add-on)------------- 'FF'
UPC-E ------------------------------ 'E' EAN-8 (8 Add-on)-------------- 'FF'
EAN-8 ---------------------------- 'FF' EAN-13 (2 add-on) ------------- 'F'
EAN-13----------------------------- 'F' EAN-13 (5 Add-on)------------- 'F'
UPC-A (2 add-on) -------------- 'A' EAN-13 (8 Add-on)-------------- 'F'
UPC-A (5 Add-on) -------------- 'A' Code 39----------------------------- '*'
UPC-A (8 Add-on) --------------- 'A' Codabar--------------------------- '%'
UPC-E (2 add-on) -------------- 'E' Interleaved.2 of 5 ---------------- 'i'
UPC-E (5 Add-on) -------------- 'E' Code 93---------------------------- '&'
UPC-E (8 Add-on) --------------- 'E' Code 128 -------------------------- '#'
EAN-8 (2 add-on)------------- 'FF' MSI/Plessey --------------------- '@'
TABLE 1. INDUSTRY STANDARD LABEL IDENTIFIERS (ALL ARE PREFIXES)
To set symbology-specific label identifiers:
1. Look at the ASCII chart on the inside back cover and identify the
ASCII character(s) and the corresponding Hex Code(s) for the ASCII
characters you will use as identifiers. You will also need to determine
whether the character(s) will need to be sent as a prefix or a suffix.
For example: You need to change the label identifier prefix for
UPC-A to 'A1'.
2. Scan the SET label below.
3. Scan either the TRANSMIT LABEL I.D. AS PREFIX or TRANS-
MIT LABEL I.D. AS SUFFIX, depending on your requirements.

4. Scan the label representing the symbology whose label identifier you
wish to modify.
In our example, we would scan the 'UPC-A' symbology label.
5. Identify and scan the digits that correspond to the Hex Values.
The hex values from the ASCII chart that correspond to 'A1'
from our example are as follows: 41hex = 'A', and
31hex ='1'. Thus,wewouldscandigitprogramminglabelsinthis
order: 4, 1, 3, 1.
6. Scan the END label.
In our example, you have changed the default label identifier
prefix for UPC-A from 'A' to 'A1'.
