Status LEDs
The scanner has two LEDs that indicate its operating status, FAULT
and COMM. The FAULT LED indicates the scanner’s overall status. The
COMM LED indicates the RIO link communication status.
The FAULT LED is off whenever the scanner is configured and
operating properly. The COMM LED state is valid only when the
FAULT LED is off.
The table below provides the scanner and communication status as
indicated by the FAULT and COMM LEDs.
IMPORTANT
If you are using Block Transfer (BT)
functionality, BTs may not function on adapters
in Hold Last State settings. Refer to each device’s
user manual for information on BTs and Hold
Last State settings.
