The WLS 9500 Product Reference Guide provides general instructions for setting up, operating, maintaining, and
troubleshooting the WLS 9500 scanner. The scanner includes the following variations of the scanner:

Service Information
If you have a problem with your equipment, contact the Wasp Technologies. Before calling, have the model number,
serial number, and several bar code symbols at hand.
Call the Support Center from a phone near the scanning equipment so that the service person can try to talk you through
your problem. If the equipment is found to be working properly and the problem is symbol readability, the Support
Center will request samples of your bar codes for analysis at our plant.
If your problem cannot be solved over the phone, you may need to return your equipment for servicing. If that is
necessary, you will be given specific directions.
Wasp Technologies is not responsible for any damages incurred during shipment if the approved
shipping container is not used. Shipping the units improperly can possibly void the warranty. If

The scanner combines excellent scanning performance and advanced ergonomics to provide the best value in a
lightweight laser scanner. Whether used as a hand-held scanner or in hands-free mode in a stand, the scanner ensures
comfort and ease of use for extended periods of time.
In addition to single-line laser scanning, the scanner supports multi-line rastering. Multi-line rastering allows the scanner
to capture stacked RSS codes and increases angular tolerances, minimizing product orientation and hand movements.
Multi-line rastering also allows the scanner to read poor quality bar codes. For more information about scanning modes
and stacked RSS codes, see Scan Pattern on page 4-7 and RSS on page B-4.
The scanner does not currently support PDF217 bar codes and its variants.

This scanner supports the following interfaces:
•Keyboard Wedge connection to a host. The host interprets scanned data as keystrokes. This interface supports
the following international keyboards (for Windows
Canadian, Spanish, Italian, Swedish, UK English, Portuguese-Brazilian, and Japanese.
•USB connection to a host. The scanner autodetects a USB host and defaults to the HID keyboard interface type.
Select other USB interface types by scanning programming bar code menus.This interface supports the

Unpacking
Remove the scanner from its packing and inspect it for damage. If the scanner was damaged in transit, call Wasp
Technologies at the telephone number listed on page xvi. KEEP THE PACKING. It is the approved shipping container
and should be used if the equipment ever needs to be return for servicing.

Setting Up the Scanner
Installing the Interface Cable
To connect the interface cable:
1. Insert the interface cable’s modular connector clip into the cable interface port on the bottom of the scanner
handle.
(See Figure 1-2.).
2. Gently tug the cable to ensure the connector is properly secured.
3. Connect the other end of the interface cable to the host. (See the specific host chapter for information on host
connections.)

Different cables are required for different hosts. The connectors illustrated in each host chapter are
examples only. Actual connectors may be different than those illustrated, but the steps to connect
the scanner remain the same.
This chapter provides beeper and LED definitions, techniques involved in scanning bar codes, general instructions and
tips about scanning, and decode zone diagrams.

Beeper Definitions
The scanner issues different beep sequences and patterns to indicate status. Table 2-1 defines beep sequences that occur
during both normal scanning and while programming the scanner.
Table 2-1. Beeper Definitions
Beeper SequenceIndication
Standard Use
Low/medium/high beepsPower up.
Short high beepsA bar code symbol was decoded (if decode beeper is enabled).
4 long low beepsA transmission error was detected in a scanned symbol. The data is ignored. This
occurs if a unit is not properly configured. Check option setting.
5 low beepsConversion or format error.
Parameter Menu Scanning
Short high beepsCorrect entry scanned or correct menu sequence performed.
Low/high beepsInput error, incorrect bar code or “Cancel” scanned, wrong entry, incorrect bar
code programming sequence; remain in program mode.
High/low beepsKeyboard parameter selected. Enter value using bar code keypad.
High/low/high/low beepsSuccessful program exit with change in the parameter setting.

empty buffer.

on and off more than once. This is normal and usually happens when the host cold
boots.
LED Definitions
In addition to beeper sequences, the scanner communicates with the user using a two-color LED display. Table 2-2
defines LED colors that display during scanning.

Scanning in Hand-Held Mode
Install and program the scanner (see Setting Up the Scanner on page 1-4). For assistance, contact the local supplier or
Wasp Te chnol ogies .
To scan in hand-held mode:
1. Ensure all connections are secure. (See the host chapter for the scanner.)
2. Aim the scanner at the bar code.
3. Press the trigger.

4. Upon successful decode, the scanner beeps and the LED turns green. (For more information about beeper and
LED definitions, see Table 2-1 and Table 2-2.)
Scan line lengths vary depending on the scan line width selected (see Scan Line Width on page 4-
8). A full scan line width is the default. Medium and short scan line widths are useful for scanning
menus or pick-lists.
Aiming
On a typical UPC 100% hold the scanner between contact and 19 inches from the symbol (see Decode Zone on page 2-
10). When scanning using a single-line scan mode, ensure the scan line crosses every bar and space of the symbol.

Figure 2-3. Acceptable and Incorrect Single-Line Aiming
012345
WLS 9500 Product Reference Guide2-6
When scanning using a multi-line scan mode, at least one scan line must cross every bar and space of the symbol.

012345
Figure 2-4. Acceptable and Incorrect Multi-Line Aiming
Regardless of the scan mode, the scan line is smaller when the scanner is closer to the symbol and larger when it is farther
from the symbol. Scan symbols with smaller bars or elements (mil size) closer to the scanner, and those with larger bars
or elements (mil size) farther from the scanner.
Do not hold the scanner directly over the bar code. Laser light reflecting directly back into the scanner from the bar code
is known as specular reflection. This specular reflection can make decoding difficult.
Scan line lengths vary depending on the scan line width selected. A full scan line width is the
default. Medium and short scan line widths are useful for scanning menus or pick-lists.
For more information about scan line widths and scanning modes, see page 4-7 and page 4-8,
respectively.
Scanning 2-7
The scanner can be tilted up to 65° forward or back and achieve a successful decode (Figure 2-5). Simple practice
quickly shows what tolerances to work within.

Scanning in Hands-Free Mode
The optional Intellistand adds greater flexibility to scanning operation. When the scanner is seated in the stand’s “cup,”
the scanner’s built-in sensor places the scanner in hands-free mode. When the scanner is removed from the stand, it
automatically switches modes to operate in its normal hand-held triggered mode.
Assemble the Stand

Scanning with the WLS 9500 Hands Free Stand
When the scanner is placed in the Intellistand, the scan pattern selected in hand-held triggered mode continues (see Scan
Pattern on page 4-7).
To operate the scanner in the WLS 9500 Hands Free Stand:
1. Ensure the scanner is properly connected to the host (see the appropriate host chapter for information on host
connections).
2. Insert the scanner in Intellistand by placing the front of the scanner into the stand’s “cup.”

3. Use the WLS 9500 Hands Free Stand’s adjustment knobs to adjust the height and angle of the scanner.
4. Present the bar code.
When the bar code is in view, the scanner emits a full scan line. After 3 minutes, the scanner
automatically switches to a reduced scan line. After 1 hour, the scanner automatically switches to
blink mode.
5. Upon successful decode, the scanner beeps and the LED turns green. For more information about beeper and
LED definitions, see Table 2-1 and Table 2-2.
