Startup

When the scanner first receives power, the blue LED will turn on and the scanner will beep once. The scanner is now ready to scan.

Power-Up Test Mode

When a MS2421/MS2422/MS2431 scanner is first powered up, it cycles through a number of self-tests before starting normal operation. If there are any initial failures during this sequence of tests the scanner will beep or razz to indicate the error and an error code will appear in the diagnostic indicator display.

The following are examples of the types of tests performed at power-up.

1.Memory tests

2.Hardware setup tests

3.Motor tests

4.Laser tests

5.Configuration tests

6.Interface tests

These tests are also performed on a periodic basis with the operator alerted to any failures.

Configuration Mode

All MS2421/MS2422/MS2431 bar code scanners have been configured at the factory with a set of default communication protocols. Since many host systems have unique formats and protocol requirements, a wide range of configurable features that may be selected with the use of the MetroSelect Configuration Guide

(PN 00-02407x), the MS2xxx Stratos Series Configuration Addendum (PN 00-02034x) and MetroSet.
