AUDIBLE INDICATORS
When the IS6520/MS6520 scanner 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 Configuration Guide (MLPN 00-02407).
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 red
light does not flash, then the bar code has not been
successfully read.
Razzberry Tone
This tone is a failure indicator. Refer to “Failure
Modes" page 10.
Three Beeps - During Operation
During operation of the scanner, the red LED will flash
while the scanner simultaneously beeps three times (while
going into programming mode).
The red LED will continue to flash until the unit exits
program mode. Upon exiting program mode, the scanner
will beep three times and the red LED will stop flashing.
When configured, 3 beeps can also indicate a
communications timeout 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.
Three Beeps - On Power Up
This is a failure indicator. Refer to “Failure Modes” on
page 10.

10
FAILURE MODES
Flashing Green and One Razzberry Tone
This indicates the scanner has experienced a laser
subsystem failure. Return the unit for repair at an
authorized service center.
Flashing Green and Red and Two Razzberry
Tones
This indicates the scanner has experienced a motor failure.
Return the unit for repair at an authorized service center.
Continuous Razzberry Tone with Both LEDs Off
If, upon power up, the scanner emits a continuous razzberry
tone, then the scanner has an electronic failure. Return the
unit for repair at an authorized service center.
Three Beeps - On Power Up
If the scanner beeps 3 times on power up then, the non-
volatile memory that holds the scanner configuration has
failed. Return the unit for repair at an authorized service
center.

11
VISUAL INDICATORS
There is a red LED and a green LED on IS6520/MS6520. When the scanner is
on, the flashing or stationary, activity of the LEDs indicates the status of the
current scan and the scanner.
No Red or Green LED
The LEDs will not be illuminated if the scanner is not receiving
power from the host or transformer.
Steady Green
When the laser is active, the green LED is illuminated. The
green LED will remain illuminated until the laser is deactivated.
During the power save mode, the laser will turn on and turn off.
During this period, the green LED remains illuminated.
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.
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.
Steady Green and Flashing Red
This indicates the scanner is in program mode. A razzberry tone
indicates that an invalid bar code has been scanned in this mode.
Steady Red, Green Off
This indicates the scanner may be waiting for communication
from the host.

12
PROGRAMMING MODES
The IS6520/MS6520 Cubit has 3 modes of programming.
Bar Codes: Cubit can be configured by scanning the bar codes located in the
MetroSelect Configuration Guide (MLPN 00-02407). Please refer to this guide for
instructions. This manual can be downloaded for FREE from Metrologic’s
website (www.metrologic.com).
MetroSet®: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 Metrologic’ website (www.metrologic.com), or set-up
disks can be ordered by calling 1-800-ID-METRO.
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 Configuration Guide.
How does Serial Programming work?
1. 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).
2. If the command sent to the scanner is valid, the scanner will respond with
an [ack].
3. 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-tranmsitting the invalid
command will not work, you must start over.
4. During programming, the motor and laser remain active. YOU CANNOT
SCAN ANY BAR CODES WHILE IN PROGRAM MODE.
5. There is a 20 second window between commands. If a 20 second timeout
occurs, the scanner will send a [nak] and you must start over.

13
PROGRAMMING MODES (CONTINUED)
6. To enter serial program mode, send the following command [stx]999999[etx].
7. To exit serial program mode, send the following command [stx]999999[etx],
the scanner will respond with an [ack] and a long beep.
8. 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.
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 emit a long beep!
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, timeouts, etc.), simply send the code bytes in the
same order that you would normally scan the bar codes.

14
PROGRAMMING MODES (CONTINUED)
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 emit a long beep!
This example illustrates 2 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.
