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.

CHANGING THE SCANNER'SINTERFACE
Scan the appropriate label below to select the desired RS-232 interface.
RS-232 INTERFACE SELECTION
Scan this label to enable the RS-232 interface.
SNI RS-232 INTERFACE SELECTION (QUICKSCAN6000/6000 PLUS ONLY)
Scan this label to enable the SNI RS-232 interface.
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.

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.
