Command
Description
When enabled, scans with the wand or laser are decoded; otherwise, they are
ignored
Resets decoder IC as though it were just powered up
Clears pacing conditions, errors
Controls the LED On/Off function
Cause the decoder to generate a status message
• General status message showing symbology of last message read, error
conditions, etc.
• Message Ready/Not Ready response (for Single Read Mode 2)
This command causes the reader to sound a tone at the selected pitch for
approximately 100 milliseconds
There are three operations that manipulate the decoder configuration as a block.
• Set default configuration
• Save configuration in non-volatile memory
• Recall non-volatile configuration
For use with laser scanning, this command causes immediate execution of
previous commands that would otherwise be postponed until the laser scan
finishes

Power Idle Mode
Laser Failure Timeout
Self Test Failure Message
Reduces current draw of processor from approximately 20 mA to 4 mA in
wand mode when the wand is inactive
Turns off the laser if the Scan Sync signal is missing after approximately
1 second, and sets the laser failure status bit
An appropriate message is transmitted at power up if the decoder Self Test
fails.
EEPROM Fault
Recognition
• ROM SELF TEST FAILED
• EEPROM SELF TEST FAILED
• RAM SELF TEST FAILED
An appropriate message is transmitted at power up if the EEPROM
checksum is incorrect.
• EEPROM FAULT
