Introduction
Orbit™ is an aggressive, omnidirectional laser bar code scanner. Light-weight
and rugged, Orbit is small in size, but BIG in performance. Designed for
applications where counter space is limited, Orbit is the ideal presentation
scanner for retail, convenience, liquor and specialty stores. In addition, Orbit’s
unique, contoured shape allows it to be picked-up and used as a hand-held
scanner when scanning large or bulky items.
Engineered with a large, easy-to-find optimal scan area, Orbit increases the
first pass read rate for maximum productivity. The scanning head can be tilted
vertically a full 30 for added flexibility when scanning various sized objects.
o
These features increase the scanning throughput without increasing the
scanner size.

Quick Start
1.) Plug in the scanner. When the MS7120 is ready to scan,
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).
2.) The scanner is shipped from the factory programmed with
default settings. To configure the MS7120 scanner to
meet the host system’s specific needs, refer to the Metro-
Select Programming Guide (MLPN 2407) for instructions
on how to enter the program mode and to select the
appropriate bar codes.

4
Operational Test
Metrologic recommends using the external power supply provided with the
scanner when operating the MS7120. When using power supplied by the host,
the host system should supply a minimum of 250 mA of current @ 5VDC.
Keyboard Wedge Scanners:
1. Connect the 10-pin modular plug of the PowerLink cable into the
scanner jack. Connect the other end of the PowerLink Y-type cable
to the PC. Connect the 5-pin female DIN side of the Y-type cable
into the keyboard connector on the PC and connect the 6-pin male
mini-DIN side into the PC.
2. Check the AC input requirements of the power supply to make sure the
voltage matches the AC outlet. Connect AC power to the transformer.
3. Listen for a single beep that indicates the scanner is ready for use.
(steady green LED and the red LED will flash once)
RS-232, Light Pen, OCIA and 46xx scanners:
1. Connect the 10-pin modular plug of the PowerLink cable into the scanner
jack. Connect the other end of the PowerLink cable (the 9-pin D-type
connector) to the PC.
2. Check the AC input requirements of the power supply to make sure the
voltage matches the AC outlet. Connect AC power to the transformer.
3. Listen for a single beep that indicates the scanner is ready for use.
(steady green LED and the red LED will flash once)

5
Scanner Installation: Powered by External Power Supply
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. Turn off the host system.
2. Make the necessary PowerLink cable connections to the scanner and
the host.
3. Connect the external transformer into the power jack on the Power Link
cable.
4. Check the AC input requirements of the power supply to make sure the
voltage matches the AC outlet. (the socket-outlet shall be installed near
the equipment and shall be easily accessible.) Connect AC power to the
transformer.
5. Turn on the host system.
NOTE:
a. When the scanner first receives power, the green LED will
turn on. Then the scanner will beep once and the red LED
will flash simultaneously.
b. Plugging the scanner into the serial port of the PC does not
guarantee that scanned information will appear at the PC. A
software driver and correct configuration setting are also
required for proper communication to occur.

6
Scanner Installation: Powered by Host Device
The MS7120 scanner interfaces terminate to a 10-pin modular jack. Connect
the 10-pin modular plug of the PowerLink cable into the jack then connect the
other end of the PowerLink cable to the host. Refer to Appendix C page 36 for
pin assignments.
1. Turn off the host system.
2. Make the necessary PowerLink cable connections to the scanner and the
host.
3. Turn on the host system.
NOTE:
a.When the scanner first receives power, the green LED will turn
on. Then the scanner will beep once and the red LED will
flash simultaneously.
b.Plugging the scanner into the serial port of the PC does not
guarantee that scanned information will appear at the PC. A
software driver and correct configuration setting are also
required for proper communication to occur.
