Introduction

The IS4320-41 ScanKey™ Laser Scanner is a wearable, fully automatic, laser

scanning device complete with keypad and LCD. Since the IS4320-41 is

positioned on the back of the hand, operators can scan data quickly and easily.

This “hands free” scanning increases operator efficiency and work

productivity. Traditional hand-held scanners require the operator to interrupt

the work flow by picking up the scanner and returning it to its stand. With the

ScanKey, not only are both hands free to perform other tasks, but the operator

is always ready and able to scan.

In addition to quick scanning, ScanKey’s 17-button keypad enables bar code

data to be manually entered. All information is displayed and then transmitted

to the host device. Portable data terminals and computers requiring RS-232 or

Light Pen Emulation communication are common host devices.

Metrologic’s HandSet™ IBM® compatible software program and simple bar

code menus make the ScanKey easy to program. Host- programmable features

can be displayed at the user’s prompt.

Two-way host communication is also a feature of the RS-232 version

ScanKey. Among other host-programmable features, operators can use either

long-range or short-range activation, establish which bar codes are to be read,

and command a “good scan” beep indicator. These features can be

accomplished through the command processing set.

The IS4320-41 ScanKey autodiscriminates all standard bar codes, including

bar code types with alphanumeric characters. Specifically assigned sequences

are provided to translate the standard numeric keys for alphanumeric data

entry.

Theory of Operation

The scanning process begins once the infrared (IR) device located behind the

window senses an object in the scan field. The IR sensor is active as long as

power is applied to the unit. When the IR sensor detects an object, the display

reads "READY TO SCAN" and the cursor flashes to show that the laser is

"ON." When the laser decodes a bar code, the scanner transmits the data to the

host system and then "beeps" to indicate the decoding is complete. The IR

sensing range can be programmed for two ranges.

Short Range Activation: The IR signal initiates the scan process if it senses

an object anywhere from the face of the window

out to approximately 4" to 7".

Long Range Activation: The IR signal initiates the scan process if it senses

an object anywhere from the face of the window

out to approximately 9" to 13".

If the object is removed from the field during the scanning process, the laser

turns off.

However, if the object stays in the field, the laser remains on for up to 2.5

seconds trying to detect another bar code. If the scanner does not detect a bar

code, the laser turns off. To reactivate the scanning sequence, remove the

object and present another.

If the same symbol stays in the field after a successful scan, the laser stays on

for approximately 4 seconds and then turns off. This prevents unintentional

reads of the same bar code. To read the same symbol more than once, remove

the object from the scan field for approximately 1 second and then present the

symbol again.

Scanner Installation

Important Note: To maintain compliance with applicable standards, all

circuits connected to the scanner must meet the requirements for SELV (Safety

Extra Low Voltage) according to EN 60950.

1. "Power off" the host system.

2. Connect the communication cable to the host device.

3. Plug the scanner cable to the communication cable.

Note: The pin assignments for the scanner cable are listed on

page 29.

4. "Power on" the host system.

Note: When the scanner first receives power, diagnostic prompts

are displayed then the scanner "beeps." "READY TO

SCAN" appears on the display.

Configuration to the Host System

Before the scanner ships from the factory, the factory programs the scanner to

a set of default parameters. However, many functions of the scanner can be

modified to meet your individual needs. The scanner’s parameters can be

modified by entering the program mode and scanning the appropriate bar

codes that appear in the Programming Guide. For a list of various parameter

settings, refer to the Default Settings section in this guide. To modify the

settings, refer to the Programming Guide.

Parts of the Scanner

LCD Display Displays the scanned or typed information on one line and a

message indicating scanner status on another. When the

cursor flashes, the laser is "on."

Keypad Used to enter and transmit numeric and alpha characters.

Alpha characters can be entered by pressing two keys in an

assigned sequence.

Input/Output Sends and receives the IR signal and Laser beam.

Window

Audible Indicators

The scanner provides sounds to signal certain conditions. To change the

volume (three settings are available) or turn the beeper off, refer to the

Programming Guide section: Beeper Tones.

One Beep When the scanner first receives power, diagnostic prompts

are displayed and then the scanner "beeps." After that, each

time the scanner successfully reads a bar code, it "beeps."

Razzberry If, upon power up, the scanner emits a razzberry tone, then

Tone the scanner has failed diagnostics.

Note: The scanner can be programmed to emit a razzberry

tone when the timeout occurs during communica-

tion between the host and scanner. Refer to the

Programming Guide section: Audible Indicators for

Communication Timeouts.

Three Beeps When the scanner enters the program mode, it beeps three

times then the message "PROGRAM MODE ENABLED"

appears. When the scanner exits the program mode, it beeps

three times and the message "READY TO SCAN"

reappears.

Note: The scanner can be programmed to emit three beeps

when the timeout occurs during communication be-

tween the host and scanner. Refer to the Programm-

ing Guide section: Audible Indicators for Commun-

ication Timeouts.
