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.

These features increase the scanning throughput without increasing the

scanner size.

ment at 1-800-ID-METRO or 1-800-436-3876.

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.

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)

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.

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.
