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.

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.
