The configuration of the MW400 reader can be changed at any time by scanning the appropriate bar code label(s) in this manual. The four types of options that can be configured are:
1) Enable and Disable Bar Code Symbologies
2) Formatting of Specific Symbologies
3) Terminating Character
4) Communications - Settings
Most labels perform a complete configuration operation, and the MW-400 reader flashes the LED three times to signify that the configuration is complete. Some Bar Code Menu options require scanning of one or more additional bar codes for completion. When doing configurations requiring additional data, the first scan produces two LED flashes, indicating another scan is expected. After the last menu label in a sequence is scanned, the MW400 reader gives three LED flashes to signify completion.
As long as each configuration is individually completed, configuration operations can be carried out completely independently There is no constraint against moving from category to category while configuring separate items.
Bar Code Menu labels are encoded in the Code 128 Symbology, using a special opening character sequence that differentiates them from normal data labels. Thus the chances of inadvertently configuring the MW-400 reader in standard scanning situations is minimized.
Syntax Errors
If an incorrect label is scanned while doing Bar Code Menu configuration, a syntax error occurs. Examples of incorrect labels are normal bar code labels, or scanning multiple menu labels out of sequence.
The MW-400 reader responds to a syntax error with four LED flashes. The user may continue the configuration operation by scanning the correct label, or may start the configuration sequence over.
