Diagnostic Indicator Display

There is a two-digit error code display located under horizontal output window near the top of the platter (see figure below).

The following is a list of possible error codes and their meanings. Some errors will require immediate scanner maintenance.

02RAM ERROR – The scanner’s Random Access Memory (RAM) is tested as faulty. Return the unit for repair at an authorized service center.

03 PROGRAM ERROR – The scanner’s software program is failing. Return the unit for repair.

INTERFACE ERROR – After power up and any application exit (e.g. MetroSet, etc.), the scanner checks the interface hardware with that chosen in configuration. If they do not agree,

04an interface error exists. Correct this problem by getting the proper hardware interface OR programming MS2421/MS2422/MS2431 configuration for the proper interface hardware attached.

CONFIGURATION ERROR – The non-volatile configuration memory did not agree with the

05data last saved. Default configuration data is then used and the scanner continues operating. This error is also accompanied by three beeps. This error will remain during operation as a reminder that this power cycle is scanning against a default-generated configuration.

COMMUNICATION ERROR – The RS232 data line is being held active. This causes the scanner to read a “break” signal constantly and continuous attempts are made to enter

06MetroSet configuration mode. A short on the RX Data line can cause this condition. It can also be the result of a laptop in power save mode. The scanner will abort attempts to enter configuration mode after a short timeout. The scanner can automatically recover from this condition once the short in the RX Data line is corrected.
