Scan
Scanning output:
You can set the image size to a VGA resolution to accommodate
older applications that require a smaller image size. When Image
VGA is set to On, the resultant image is 640x480 pixels. When
Image VGA is Off, the image is 752x480 pixels.
Scanning mode:
Manual/Serial Trigger Mode
When in manual trigger mode, the imager scans until a bar code is
read, or until the hardware trigger is released.
When in serial mode, the imager scans until a bar code has been
read or until the deactivate command is sent. In serial mode, the
imager can also be set to turn itself off after a specified time has
elapsed (see Read Time-Out, which follows).
Manual Trigger, Low Power (For RS-232 only)
The imager powers down until the trigger is pulled. When the
trigger is pulled, the imager powers up and operates until there is
no triggering for the time set with the Low Power Time-Out bar
code below. There is a delay of up to one second in operation
when the imager is first triggered, but there is no delay when
operating in low power time-out mode.
