PowerScan use only the programming bar codes in this manual and other productspecific publications to program scanner features.

This manual has been developed to make it quick and easy for users of all levels to find the information needed to understand and configure scanner features. The following descriptions will help you to determine where to go from here.

™

Understanding the Basics

If you have little or no prior experience with programming using bar code labels, you should review this introductory section to familiarize yourself with the basics of scanner programming before performing any changes to you r scanner ’s co nfiguration. Contents of this section are:

Programming Guide 1

Integrating the Scanner With Your Host System

Your scanner MUST be equipped with the correct hardware (interface board, cable, etc.) to properly communicate with your host system. Contact your PSC dealer for information if you have questions about your scanner’s hardware compatibility.

You may also want to contact the dealer or your system administrator if you have no record of how your scanner was pre-programmed at the factory. Scanners are typically programmed with the default settings for specific interface types, however, your scanner may have been custom configured with settings that are unique to your company or application.

Once you know the scanner’s current settings, you can determine what changes will be required to allow communication with your host system and/or optional features you choose to modify to customize your installation. After recording the modifications needed, finish reading this section, then turn to the appropriate page and follow the instructions to program the scanner.

When all scanner features are programmed to your satisfaction, the scanner is ready to be placed into operation.

Changing Interfaces

When moving the scanner to a host terminal of a different interface type than previously connected, it may be necessary to alter the scanner’s hardware and/or software to allow connecti on and communication between the two devices.

Hardware

Interface

Board

An interface board swap is usually unnecessary, since multiple host interface protocols are supported in combination on most interfa c e boards. For example, RS-232, Standard Keyboard Wedge, and Wand Emulation are all available on a single interface board. Activation of alternate available interfaces on these boards requires only that you connect the scanner to the new host using the appropriate interface cable. The scanner will automatically chan ge to the interface functions specific to that cable.

2 PowerScan™ Scanner

T o determine if your desir ed new interface is available on your scanner, check the following section titled Software on page 4. The section lists host interface types supported by each interface board available at the time of this writing. If you are still unsure of your scanner’s available interface connectivity, consult your PSC dealer.

The scanner will need to be sent to a Level I Service repair depot if the interface board must be swapped; however, if necessary, you can change your sc ann e r’s interface cable by following these instructions. (Refer to Figure 1.):

1. Loosen the screw at the bottom of the handle. This screw is

captive and does not come all the way out.

DO NOT try to pull the end cap off, as this may damage the scanner.

CAUTION

2. Swing the forked cable retainer clear of the square hole in the

end cap and rotate away from the cable.

3. Holding the scanner handle and end cap together in one hand,

pull the connector out of the handle end cap to free the interface cable.

4. Connect the new interface cable at the scanner and rotate the

forked cable retainer to secure it. Tighten the screw to between 6 and 10 in-lbs.

Figure 1. Removing/Replacing the Interface Cable

4 PowerScan™ Scanner

After familiarizing yourself with the basi c scanner programming procedures in this section, turn to the appropriate interface programming section (RS-232, Wand Emulation, etc.) of this manual to set other interface features, completing the scanner’s conversion to a new interface type.

Upon changing a scanner’s interface setting, scan a bar code to verify that the scanner communicates correctly with the new host system. Some sample bar codes are provided in Appendix B: Sample Bar Codes on page 145. If any changes to the scanner’s factory settings are needed, consult Customizing Your Scanner’s Operation below.

Customizing Your Scanner’s Operation

Most scanner programming falls within three general categories:

• Interface Selection and Settings - are the mandatory settings

necessary to allow communication with your host terminal. Examples of these settings are: RS-232 baud rate and parity.

Ensure that your planned modifications are compatible with the current interface. For example, baud rate selections are only valid in the RS-232 interface. The scanner will sound an error tone when scanning programming labels for features

NOTE

invalid to the current interface group.

• Symbology Selection and Settings - gives the scanner the

capability to autodiscriminate as few as one, and as many as all available symbologies. For optimal scanner performance enable only those symbologies required. Additionally the scanner may be programmed with the standard options available for the various symbologies, such as check d igit, minimum label length, fixed and variable length bar codes, QuadraLogic Decoding, etc.

• General Feature Set tings - are feat ures common to all interface

types. Examples include beeper adjustments such as volume and length, read verification settings, etc.

If you experience difficulties, have questions or require additional information, contact your local distributor, or call your dealer or sales representative.

Programming Guide 5

Programming Overview

The scanner’s programmable feature settings can be modified to accommodate your system’s unique requirements. These settings can be communicated to the scanner in one of two ways:

1. Commands can be sent directly from the host. A limited set of

host command s are available. Refer to Appendix A: Additional

Information on page 143 for more details.

2. The easiest, most comprehensive way to program the scanner

is to use the Configurator Express™ On-Screen Programmining

Kit. Ask your dealer for more information about this product.

3. Programming bar code labels can also be used to modify the

scanner’s programmable settings. This manual provides the bar code labels and instructions necessary to configure the scanner’s features/options.

NOTE

What Is Programming Mode?

When you program the scanner using any of the methods above, the scanner will store the changes until reprogrammed or returned to factory defaults.

Programming Mode is a state in which the scanner must be placed in order to accept programming commands. When programming using the bar code labels in this manual, the scanner is typically placed in Programming Mode by scanning the “SET” label at the top of most programming feature pages.

While in the Programming Mode, the scanner only recognizes the special programming bar codes contained in this programming guide. See the section, LED and Beeper Indicators on page 11 for information about scanner indications while in the Programming Mode.

6 PowerScan™ Scanner

Programming Session

A typical programming session is conducted as follows:

1. Scan the SET bar code at the beginning of each set of program-

ming bar codes to place the scanner in Programming Mode. The scanner will emit three beeps, indicating it has read the bar code and the green LED will flash on and off slowly while the scanner remains in Programming Mode. Normal scann ing functions are disabled.

2. Scan the programming label(s) that is (are) specially encoded

to make the desired changes. With few exceptions

, the scanner will emit a triple beep each time you scan a valid programming bar code.

Not all features are available for all interfaces and the scanner will sound an error tone when scanning programming bar codes for features invalid to the current interface. Only features supported by the currently active interface will

NOTE

be implemented.

If a label is scanned that changes the scanner’s interface, all previous configuration items scanned in the programming session

NOTE

are lost.

Additionally, when programming a feature requiring you to scan single digits to set a multi-digit number, such as Minimum Label Length, scanning the END bar code (or any item tag/item value bar code) before completing all input will result in an error tone and cause the scanner to exit Programming Mode. Under these circumstances, the current feature you were trying to set is thrown out; any previous bar codes scanned during the session will take effect.

1. Some features, such as Minimum Label Length, require you to select the label’s length by scanning a series of single-digit bar codes. A single ‘good read’ beep is soun d ed wh en sc an n in g th es e single digits in Programming Mode. Only the final required digit in the sequence will produce a triple beep when scanned, indicating a successfully programmed feature.

Programming Guide 7

It is recommended that programming sessions be limited to one feature at a time. Should you make a mistake in the programming sequence, it can be difficult to discover where an error has been made if several features are programmed at once. Additionally, it

NOTE

3. Scan the END label at the bottom of the page to save any new

settings and exit Programming Mode. The scanner will sound a beep and reset upon exiting Programming Mode, and the green LED will return to its usual state (on steady or off).

The scanner will not exit Programming Mode unless the END bar code is scanned or power is disconnected. Disconnecting power during Programming Mode, before scanning the END label, will cause all new settings to be ignored. On power-up, the scanner will return to previous settings.

4. Maintain a good record of all changes made to ensure that you

know if the original factory settings have been changed.

can be confusing to determine which features may or may not have been successfully set following such a session.

8 PowerScan™ Scanner

Programming

Sequence

To modify a scanner feature (item), the programming bar codes contained in this manual must be scanned in a given sequence depending upon the feature being programmed (as shown in Table 1). There are three possible programming sequences:

A. Programming sample A (the most commonly used format)

demonstrates how three bar codes are scanned in sequence to do the following:

1. Place the scanner in Programming Mode (SET bar code).

2. Scan the Item Tag

that will enable the new feature.

3. End the programming session and reset the scanner (E ND bar code).

B. Sample B provides an example of a programming feature

requiring the entry of a range value. Like sample A, the scanner is placed in Programming Mode and an Item Tag

is scanned. Then, a value must be entered before ending the programming session. In the example, three digits must be scanned fr om th e nu mber p ad in Appendix C : Ke ypad. This type of format, requiring a total of as many as six programming bar codes, is necessary to allow flexible programming with larger item value numeric ranges.

C. The programming sequence shown in example C requires

scanning of a single, extended length bar code. This special programming bar code contains all the data necessary to enter

Programming Mode, set the Item Tag

and Item V alue, and exit

Programming Mode (all in one step).

1. An “Item Tag” is a term used to describe an assigned number, which is encoded in a programming bar code, that toggles (selects, enables, disables, etc.) a specific programming feature.

If You Make a Mistake...

If, during a programming session, you find that you are unsure of the scanner’s settings or wish to reset the scanner’s configuration, use the Return to Factory Settings label below to return the scanner’s configuration to the factory settings. Scannin g this label will also reset any changes made during previous programming sessions.

Return to Factory Settings

Scan this label to return the scanner to the default settings configured at the factory. This label is typically used to return the scanner to a “known” operating state when the present programming status is not known, faulty, or suspect.

CAUTION

Where To Go From Here

Programming is easy and straightforward if you fol low these steps:

NOTE

1. If you are changing the scanner’s interface type, follow the

instructions in the section titled, Changing Interfaces on page 2 before proceeding.

2. Scan any feature bar codes that are unique to the interface you

are currently programming. These interface specific programming bar codes immediately follow each interface selection label.

3. Turn to Symbologies Supported on page 60 if you are going to

change any bar code symbologies o r modify any symbologyrelated features.

If you are changing some interface types (for example; if you are mo ving th e scanner f r om a Universal Keyboard Wedge to an RS-232 host) you must first change the hardware. Replace the scanner’s interface board (if required) and connect the scanner using the new interface cable BEFORE performing any programming changes.

4. Turn to General Features on page 130 if you wish to change or

modify any of the scanner’s other features.

Once the necessary changes have been made, and you have scanned the END bar code, you are ready to scan.

Hardware

Handshaking

CTS/RTS Flow Control - is hardware handshaking. The scanner acti-

vates the RTS (Request to Send) line when it is ready to send data to the host. The scanner waits for an active Clear to Send (CTS) signal from the host before transmitting data. If hardware control is disabled, CTS/ RTS communication will not take place. If the host deactivates the CTS line during data transmission, the host will receive additional characters for no more than 2ms
