Product Reference Guide 1
Programming the QS2500
To program the QS2500, you must scan a series of programming bar
codes in the correct order. The inside back cover of this manual contains a table of alphanumeric bar codes needed to program the various
options.
To program each option:
1. Scan the Start Program bar code above the list of options (see
the table below).
2. Enter the option mode by scanning the Option bar code.
3. Find the alphanumeric entry for the option setting you want,
and scan the alphanumeric characters located in Appendix E.
4. Scan the Finish bar code in Appendix E.
5. Scan the Exit bar code.

Interfaces
The QS2500 supports four interfaces, Keyboard Wedge, RS-232, Wand
Emulation and USB. The correct interface cable is included for the scanner interface type you ordered.
Keyboard Wedge
As a keyboard interface, the QS2500 supports most popular PCs and
IBM terminals. The installation of the wedge is a fairly simple process
that doesn’t require any changes of software or hardware.

Caps Lock:
By selecting Caps Lock or No Caps Lock, the QS2500 can get
Caps Lock status.
Power-On Simulation:
All PCs check the keyboard status during the
power-on selftest. It is recommended that you enable this function if
you are working without a keyboard installation. It simulates keyboard
timing and passes the keyboard status to the PC during power-on.
Intercharacter Delay:
This delay is inserted after each data character
transmitted. If the transmission speed is too high, the system may not
be able to receive all characters. You may need to adjust the delay to
make the system work properly.
Block Transmission Delay:
This is a delay timer between bar code data
outputs. The feature is used to transfer continually with shorter bar
code data or multifield scanning.

Product Reference Guide 7
None:
The communication uses only TxD and RxD signals, without regard for any hardware or software handshaking protocol.
RTS/CTS:
If the QS2500 wants to send the bar code data to the host
computer, it will issue the RTS signal first, wait for the CTS signal from the host computer, and then perform the normal data
communication. If there is no replied CTS signal from the host
computer after the timeout (response delay) duration, the
QS2500 will issue five warning beeps.
Xon/Xoff:
sends an Xoff code to inform the QS2500 to suspend data transmission and an Xon to continue.
When the host computer is unable to accept data, it
ACK/NAK:

The trigger button acts as a toggle switch. Pressing the

The trigger button must be pressed to activate scanning, and the QS2500 stops scanning when no code is decoded
after the standby duration has elapsed.
The QS2500 always keeps reading, and it does not matter whether the trigger button is pressed or the standby duration has elapsed.
Test only:
The QS2500 always keeps a constant reading, and samelabel reading is allowed without double confirmation. The feature can test the performance of the QS2500 for reading speed
and sensitivity.
Standby Duration:
A timeout duration of 1 to 99 seconds can be set. It is
effective only when the CCD scanning mode is operated in timeout-off
mode and good-read off mode.
Same Bar Code Delay Time:
If the bar code has been scanned twice, then
only the first bar code will be accepted.
Double Confirm:
If this option is enabled, the QS2500 will require a several successful decodings to confirm the bar code data. Larger settings
will make misreads less likely. If a double confirm is set, the multifield
scan function will be disabled.
Multifield Scan:
The QS2500 can be read many sets of bar code data on
the same scanning line at the same time, even if they are different kinds
of bar code symbology.

these limits will be rejected. Make sure that the minimum-length setting is no greater than the maximum-length setting; otherwise, the
labels of the symbology will not be readable. In particular, you can set
the same value for both minimum and maximum lengths to force
decoding of only fixed-length bar codes. This setting has no effect on
