INSTALLING THE IS6520-47/MS6520-47 TO THE PC
1. Turn off the PC.
2. Connect the 10-pin RJ45 male connector into the jack on the Cubit™
IS6520/MS6520. You will hear a ‘click’ when the connection is made.
3. Connect the L-shaped plug of the power supply into the power jack on the
PowerLink cable. Refer to Manufacturer’s Recommendation below.
4. Connect the power supply into an AC outlet. Make sure the AC input
requirements of the power supply match the AC outlet.
5. Disconnect the keyboard from the PC.
6. The PowerLink cable is terminated with a 5-pin DIN female connector on
one end, and a 6-pin mini DIN male on the other. Metrologic will supply an
adapter cable with a 5-pin DIN male connector on one end and a 6-pin mini
DIN female connector on the other. According to the termination required,
connect the appropriate end of the adapter cable to the PowerLink cable,
leaving the necessary termination exposed for connecting to the keyboard
and the keyboard port on the PC. Refer to Appendix C page 31 for pin
assignments.
7. Connect to the PowerLink cable to the keyboard and the keyboard port on
the PC.
8. Power up the PC.
Manufacturer’s Recommendation:
Metrologic recommends the use of an external power supply with IS6520-
47/MS6520 Keyboard Wedge applications. Powering the IS6520-47/MS6520
directly from the computer keyboard connector could interfere with the operation
of the scanner or the computer. Not all computers supply the same current
through the keyboard port, explaining why a scanner would work on one
computer and not another.
Caution:
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.

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®Programming Guide MLPN 2407.
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.
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.

11
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.

12
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.

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 2407). 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 (MLPN 2407).
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.
