Aiming

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.

The scanner can be tilted up to 65° forward or back and achieve a successful decode (Figure

2-3). Simple practice quickly shows what tolerances to work within.

User Preferences

Introduction

The scanner can be programed to perform various functions, or activate different features.
This chapter describes each user preference feature and provides the programming bar
codes necessary for selecting these features for the scanner.

The scanner ships with the settings shown in the User Preferences Default Table on page
4-4 (also see Chapter A, Standar d Default Parameters for all host device and miscellaneous
scanner defaults). If the default values suit the requirements, programming may not be
necessary.

Feature values are set by scanning single bar codes or short bar code sequences. The
settings are stored in non-volatile memory and are preserved even when the scanner is
powered down.

If the USB cable is not being used, select a host type (see each host chapter for specific host
information). After hearing the power-up beeps, select a host type. This only needs to be
done once, upon the first power-up when connected to a new host.

To return all features to their default values, scan the Set All Defaults bar code on page 4-

5. Throughout the programming bar code menus, default values are indicated with asterisks
(

*).

4-3

* Indicates Default

*High Frequency

Feature/Option

Scanning Sequence Examples

In most cases, only one bar code needs to be scanned to set a specific parameter value. For
example, to set the beeper tone to high, simply scan the High Frequency (beeper tone) bar
code listed under Beeper Tone on page 4-5. The scanner issues a fast warble beep and the
LED turns green, signifying a successful parameter entry.

Other parameters, such as specifying Laser On Time or setting Data Transmission
Formats, require that several bar codes be scanned. See Laser On Time on page 4-7 and
Scan Data Transmission Format on page 9-7 for descriptions of this procedure.

Errors While Scanning

Unless otherwise specified, if an error is made during a scanning sequence, just re-scan the
correct parameter.

Laser On Time

This parameter sets the maximum time that decode processing continues during a scan
attempt. It is programmable in 0.1 second increments from 0.5 to 9.9 seconds. The default
Laser On Time is 3.0 seconds.

To set a Laser On Time, scan the bar code below. Next, scan two numeric bar codes
beginning on page D-1 in Chapter D, Numeric Bar Codes that correspond to the desired on
time. Single digit numbers must have a leading zero. For example, to set a Laser On Time
of 0.5 seconds, scan the bar code below, then scan the “0” and “5” bar codes. In case of an
error, or to change the selection, scan Cancel on page D-7.

Trigger Mode

The scanner has three trigger modes that can be used to scan bar codes. The desired trigger
mode can be set by using the bar codes below.

Level Trigger

When the trigger is pulled, an aiming dot appears for a programmable duration of time.
After this time, the aiming dot automatically turns into a standard laser scanning beam for
a full decode session. The laser scanning beam stays on until the laser-on timeout occurs, a
decode occurs, or the trigger is released. If the trigger is released before the aiming duration
expires, the laser shuts off and no decode occurs.

*Level

User Preferences

Trigger Mode (continued)

Two Stage - Option 1

When the trigger is pulled, an aiming dot appears. This aiming dot remains while the trigger
is pulled. When the trigger is released, the aiming dot automatically turns into a standard
laser scanning beam for a full decode session. The laser scanning beam stays on until the
laser-on timeout occurs or a decode occurs. If the trigger is pulled again while in a decode
session, the scanner beam returns to an aiming dot.

Tw o Stage - Option 1

Two Stage - Option 2

When the trigger is pulled, an aiming dot appears. When the trigger is released, the aiming
dot turns off. Pulling the trigger twice in rapid succession turns on the standard laser
scanning beam for a full decode session. The laser scanning beam, stays on until the laser­on timeout occurs, a decode occurs, or the trigger is released.

Tw o Stage - Option 2

4-10

WLS 8400 Product Reference Guide

Aim Duration

When the scanner is in Level trigger mode (default mode), Aim Duration sets the amount
of time the aiming dot is seen before turning into a scanning beam. This parameter has no
affect when the scanner is in either of the Two Stage trigger modes. See Trigger Mode on
page 4-8 for a description of each of the trigger modes.

The aim duration is programmable in 0.1 second increments, from 0.0 to 9.9 seconds. The
default Aim Duration is 0.0 seconds. When set to 0.0 seconds, no aiming pattern appears
before a decode session.

To set an aim duration, scan the bar code below. Then scan two numeric bar codes,
available in Appendix D, Numeric Bar Codes, that correspond to the desired aim duration.
Durations less than 1.0 seconds must have a leading zero. For example, to set an aim
duration of 0.5 seconds, scan the bar code below, followed by the ‘0’ and the ‘5’ bar codes.
In case of an error, or to change the selection, scan the ‘Cancel’ bar code on page D-7.

Keyboard Wedge Interface

Introduction

This chapter provides Keyboard Wedge interface information for setting up the scanner.
This interface type is used to attach the scanner between the keyboard and host computer.
The scanner translates the bar code data into keystrokes. The host computer accepts the
keystrokes as if they originate from the keyboard.

This mode of operation allows adding bar code reading functionality to a system design ed
for manual keyboard input. In this mode, the keyboard keystrokes are simply passed
through.

Throughout the programming bar code menus, default values are indicated with asterisks
(

Ignore Unknown Characters

Unknown characters are characters the host does not recognize. When Send Bar Codes
With Unknown Characters is selected, all bar code data is sent except for unknown
characters, and no error beeps sound on the scanner. When Do Not Send Bar Codes W ith
Unknown Characters is selected, bar code data is sent up to the first unknown character

and then an error beep sounds on the scanner.

ASCII Character Set

Code 39 Full ASCII interprets the bar code special character
($ + % /) preceding a Code 39 character and assigns an ASCII
character value to the pair. For example, when Code 39 Full ASCII is
enabled and a +B is scanned, it is interpreted as b, %J as ?, and %V
as @. Scanning ABC%I outputs the keystroke equivalent o f ABC >.

RS-232 Interface

Introduction

This chapter provides RS-232 host information for setting up the scanner. The RS-232
interface is used to attach the scanner to point-of-sale devices, host computers, or other
devices with an available RS-232 port (i.e., com port).

If the particular host is not listed in Table 6-2, set the communication parameters to match
the host device. To set communication parameters for hosts not listed, refer to the
documentation for the host device.

This scanner utilizes TTL RS-232 signal levels, which interfaces with
most system architectures. Please contact Wasp Support for more
information.

Throughout the programming bar code menus, default values are indicated with asterisks

Interface

Interface cables vary depending on configuration. The connectors
illustrated in Figure 6-1 are examples only. The connectors may be
different than those illustrated, but the steps to connect the scanner
remain the same.

1. Attach the modular connector of the RS-232 interface cable to the cable interface
port on the scanner. (See Installing the Interface Cable on page 1-5.)

2. Connect the other end of the RS-232 interface cable to the serial port on the host.

3. Connect the power supply to the serial connector end of the RS-232 interface cable.
Plug the power supply to an appropriate outlet.

4. Ensure that all connections are secure.

5. Select the RS-232 host type by scanning the appropriate bar code from the RS-232

Host Types section on page 6-9.

6. To modify any other parameter options, scan the appropriate bar codes in this
chapter.

Parameter

*In the Nixdorf Mode B or OPOS/JPOS, if CTS is Low, scanning is disabled. When CTS is High, the user can scan
bar codes.

**If Nixdorf Mode B or OPOS/JPOS is scanned without the scanner connected to the proper host, it may appear
unable to scan. If this happens, scan a different RS-232 host type within 5 seconds of cycling power to the scanner.

Parity

A parity check bit is the most significant bit of each ASCII coded character. Select the
parity type according to host device requirements .

Select Odd parity with the parity bit value set to 0 or 1, based on data, to ensure that an odd
number of 1 bits are contained in the coded character.

Odd

Select Even parity with the parity bit value set to 0 or 1, based on data, to ensure that an
even number of 1 bits are contained in the coded character.

Even

Select Mark parity and the parity bit is always 1.
