INDICATOR DESCRIPTIONS

Diagnostic Indicator Display

There is a two-digit error code display located under horizontal output window near the Metrologic logo on the platter (see

figure below).

Figure 31. Error Code Display (Optional Product Roll Bar Shown)

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

ERROR

CODE DESCRIPTION

01 Reserved

02 RAM 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, an interface error exists. Correct this

problem by getting the proper hardware interface OR programming StratosS configuration for the proper interface

hardware attached.

CONFIGURATION ERROR – The non-volatile configuration memory did not agree with the data last saved. Default

configuration data is then used and the scanner continues operating. This error is also accompanied by 3 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 MetroSet 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.

COPROCESSOR COMMUNICATION ERROR – The main microprocessor is not communicating with the interface

coprocessor. The interface coprocessor may be in a fault condition with the host or just not able to respond. This

error may appear when the scanner is configured for USB or IBM interface applications or during an attempt to

update the interface software through the flash utility. The unit should be repaired at an authorized service center.

SWITCH ERROR – The switch used for volume selection or sleep mode is detected in error (always closed). The

condition is self-correcting if possible. If the error persists, return the unit for repair at an authorized service center.

The scanning operation can continue with this error active.
