Diagnostic Indicator Display; Error Codes - Honeywell MS2431 Installation And User Manual

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.
Error
Code
01 Reserved
RAM ERROR – The scanner's Random Access Memory (RAM) is tested as faulty. Return the
02
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,
04 an 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
data last saved. Default configuration data is then used and the scanner continues operating.
05
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
MetroSet configuration mode. A short on the RX Data line can cause this condition. It can
06
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.
