Operating Modes
Scan Mode
The imager can be set to operate in one of several scanning
modes. See the PRG for more information and settings for any
of the options:
Trigger Single (Default):
This mode is associated with typical
handheld reader operation. Motion Sense is active and if the
scanner detects motion the aiming pattern is turned on. When
the trigger is pulled, illumination is turned on and the scanner
attempts to read a label. Scanning is activated until one of the
following occurs:
• the programmable “maximum scan on time”
1
has
elapsed
• a label has been read
• the trigger is released
Trigger Pulse Multiple:
Scanning begins when the trigger is
pulled and continues after the trigger is released, until the trig-
ger is pulled again or until the programmable “maximum scan
on time”
1
has elapsed. Reading a label does not disable scan-
ning. Double Read Timeout
1
prevents undesired multiple
reads while in this mode.
Trigger Hold Multiple :
When the trigger is pulled, scanning
starts and the product scans until the trigger is released or
“maximum scan on time”
1
has elapsed. Reading a label does
not disable scanning. Double Read Timeout
1
prevents unde-
sired multiple reads while in this mode.
Always On:
The illuminator is always ON and the reader is al-
ways ready for code reading. Double Read Timeout
1
prevents
undesired multiple reads.
Flashing:
The reader illuminator flashes on and off regardless
of the trigger status. Code reading takes place only during the
Flash On
2
time. Double Read Timeout
1
prevents undesired
multiple reads.
