1 Introduction
The iSCAN100 is the latest development in barcode scanning technology for
Zone 1 and Zone 2 hazardous areas. The unit offers a very high specification
but at an affordable price as it is based on the very latest ideas in Ex
protection technology.
The scanner is ergonomically designed in an IP55 pistol grip housing that is
comfortable to use for an operator, even when wearing gloves. The housing has
a rubber protective shield to protect it from dropping on to hard floors.
Supplied with a spiral cable the iSCAN100 can be connected to systems by a
PS2 keyboard wedge or an RS232 serial interface. Most popular barcode
symbologies are supported by the built-in decoder providing the PC or operator
terminal with ASCII data.
A friction free scanning mechanism is designed to be highly reliable and give a
long service life. Scanning 72 times per second at up to 33 cm away from the
barcode makes this unit very practical to use for demanding applications .
Each type is rigorously checked and tested by Extronics to ensure conformity
to the ATEX standards and approvals.

4.2 Audible Indicators
When the iSCAN100 is in operation, it provides audible feedback. These sounds
indicate the status of the scanner. Eight settings are available for the tone of the
beep (normal, 6 alternate tones and no tone). To change the tone, refer to the
MetroSelect
®
Single-Line Programming Guide included with the scanner.
Alternativleysee the help files contained in the MetroSet
®
2 help files.
One Beep
When the scanner first receives power, the green LED will turn on, then the red
LED will flash and the scanner will beep once. (The red LED will remain on for
the duration of the beep.) The scanner is ready to scan.
When the scanner successfully reads a bar code, the red LED will flash and the
scanner beeps once (if programmed to do so). If the scanner does not beep once
and the green light does not flash, then the bar code has not been successfully
read.
Two Beeps — On Power Up
When there is a Flash ROM upgrade needed, the scanner will beep twice
followed by alternating flashing of the green and red LEDs.
Three Beeps - During Operation
When entering configuration mode, the red LED will flash while the scanner
simultaneously beeps three times. The red and green LEDs will continue to flash
while in this mode. Upon exiting configuration mode, the scanner will beep three
times, and the LEDs will stop flashing.
When configured, 3 beeps can also indicate a communications time-out
during normal scanning mode.
When using one-code-programming, the scanner will beep three times (the
current selected tone), followed by a short pause then by a high tone and a low
tone. This tells the user that the single configuration bar code has successfully
configured the scanner.
Raspberry Tone\Three Beeps - On Power Up
This is a failure indicator. Refer to "Failure Modes" on page 14.

13
4.3 Visual Indicators
The iSCAN100 has three LED indicators (green, red and yellow) located on the
head of the scanner. The MS9520 has two LED indicators (green and red) located
on the head of the scanner. When the scanner is on, the flashing or stationary
activity of the LEDs indicates the status of the current scan and the scanner.
Green & red LED’s off
The LEDs will not be illuminated if the scanner is not receiving power from
the host or transformer. The scanner is stand-by mode, and CodeGate
®
is
enabled. Present a bar code to the scanner and the green LED will turn on
when the laser turns on.
Steady Green
When the laser is active, the green LED is illuminated. The green LED will
remain illuminated until the laser is deactivated. (Default Mode Only)
Steady Green and Single Red Flash
When the scanner successfully reads a bar code, the red LED will flash and the
scanner will beep once. If the red LED does not flash or the scanner does not
beep once, then the bar code has not been successfully read.
(Default Mode Only)
Steady Green and Steady Red
After a successful scan, the scanner transmits the data to the host device. Some
communication modes require that the host inform the scanner when data is ready
to be received. If the host is not ready to accept the information, the scanner's red
LED will remain on until the data can be transmitted.
Alternating Flashing of Green and Red
This indicates the scanner is program mode. A raspberry tone indicates that an
invalid bar code has been scanned while in this mode.
The scanner needs to have a Flash ROM upgrade if the alternating flashing of the
red and green LEDs occurs during start-up and is accompanied by three beeps.
Steady Red, Green off
This indicates the scanner may be waiting for communication from the host.

14
4.4 Failure Modes
Flashing Green and one Raspberry Tone
This indicates the scanner has experienced a laser sub-system failure. Return
the unit for repair to an authorized service centre.
Flashing Red and Green with Two Raspberry Tones
This indicates the scanner has experienced a scanning mechanism failure.
Return the unit for repair to an authorized service centre.
Continuous Raspberry Tone with all LEDs off
If, upon power up, the scanner emits a continuous raspberry tone, then the
scanner has an experienced an electronic failure. Return the unit for repair to
an authorized service centre.
Three Beeps – on power up
If the scanner beeps 3 times on power up then the non-volatile memory
(NovRAM) that holds the scanner configuration has failed. If the scanner does
not respond after reprogramming, return the scanner for repair to an
authorized service center.

15
4.5 Programming Modes
The ISCAN100 has 3 modes of configuration.
•Bar Codes
iSCAN100 can be configured by scanning the bar codes located in the
MetroSelect
®
Single-Line Programming Guide supplied with the
scanner. Please refer to this guide for instructions.
•MetroSet
®
2
This user-friendly Windows-based configuration program allows you to simply
`point-and-click' at the desired scanner options. This program can be
downloaded for FREE from the following URL:
www.europe.metrologic.com/europe/download/software/metroset2install.exe.
•Serial Programming
This mode of programming is ideal for OEM applications. This mode gives
the end-user the ability to send a series of commands using the serial port of
the host system. The commands are equivalent to the numerical values of
the bar codes located in the MetroSelect Single-Line Programming Guide
supplied with the scanner.

16
4.6 Serial Programming
Each command sent to the scanner is the ASCII representation of each numeral in
the configuration bar code. The entire numeric string is framed with an ASCII [stx]
and an ASCII [etx].
EXAMPLE #1:
Command for Disabling Codabar Command = [stx]100104[etx]
String Sent to Scanner = 02h 31h 30h 30h 31h 30h 34h 03h
(All values are hexadecimal).
If the command sent to the scanner is valid, the scanner will respond with an [ack].
If the command sent to the scanner in invalid, the scanner will respond with a
[nak].
NOTE: If this occurs, the end-user must start over at the very beginning of the
configuration sequence. Simply re-transmitting the invalid command will not work,
you must start over.
During programming, the motor and laser turn off. YOU CANNOT SCAN A BAR
CODE WHILE IN SERIAL PROGRAM MODE.
There is a 20 second window between commands. If a 20 second time-out occurs,
the scanner will send a [flak] and you must start over.
To enter serial program mode, send the following command [stx]999999[etx].
To exit serial program mode, send the following command [stx]999999[etx], the
scanner will respond with an [ack] followed by 3 beeps.
This mode uses the current Baud Rate, Parity, Stop Bits and Data Bits settings
that are configured in the scanner. The default settings of the scanner are 9600,
Space, 2, 7 respectively. If a command is sent to the scanner to change any of
these settings, the change will NOT take effect until after serial program mode is
exited.

17
EXAMPLE #2:
The following example will set the scanner to the factory default settings, Disable
Scanning of Code 128 bar codes, change the beeper tone, and add a "G" as a
programmable prefix.

Exit Program Mode [stx]999999[etx] 02h 39h 39h 39h 39h 39h 39h 03h [ack] or 06h
The scanner will beep three times!
The commands sent to the scanner do not include the small superscripted `3' that
you see in front of each bar code string in the MetroSelect manual. THE '3'
SHOULD NOT BE SENT, IT IS A CODE TYPE DESIGNATION ONLY!
As you will note for commands requiring additional bar codes to be scanned (such
as prefixes, suffixes, time-outs, etc.), simply send the code bytes in the same order
that you would normally scan the bar codes.

18
EXAMPLE #3:
The following example shows the events that occur when an invalid bar code is sent.
This sample will load the factory default settings and then set the baud rate to
19200.

The scanner will beep three times!
This example illustrates two important points.
First, if an invalid command is sent from the host, the scanner responds with a [nak]
and the end-user must start over from the beginning.
Second, if a command is sent to change the Baud Rate, the new baud rate does
not take effect until after the end-user exits program mode.

4.7 Upgrading The Flash ROM Firmware
The Meteor program is a functional component of Extronics new line of Flash-
based scanners. This program allows the user of Extronics scanner to quickly
upgrade to a new or custom version of software. It requires the use of a personal
computer running under Windows 95 or greater and the use of a communication
port. The user merely connects the scanner to a communications port of the PC,
launches the Meteor program, and blasts off to new software upgrades.
Each MS9500, regardless of the version number or communication protocol, can
be upgraded. In other words, all RS232 (-41), keyboard wedge (-47), light pen (-
41), laser emulation (-00), OCIA (-9) and IBM 468X/469X (-11) units can be
upgraded. To upgrade all units, a power supply and PowerLink cable (MLPN 54-
54012) are required.
The upgrades and custom software versions will be supplied by Extronics in files
called Motorola S-record files. These files contain all the information needed to
upgrade the scanner. Simply add this file to the working directory or retrieve from
its current location.
The program guides the user with its simplistic one click approach. The user must
first select the file; once selected and verified, the file is ready to be used in the
upgrade. Press the button to upgrade the scanner, the unit will go into a "flash
mode" — both the green and red LEDs will be on. The user can follow the progress
of the upgrade by watching the screen for details. When the upgrade is complete,
the scanner will respond with its normal one beep on power up. If two beeps occur,
the scanner did not upgrade properly. (Contact an Extronics for additional details).
