7.1 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
You can activate the imager either by providing an external hardware trigger, or using a serial trigger command . 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).
Read Time-Out
Use this selection to set a time-out (in milliseconds) of the imager’s trigger when using serial commands to trigger the imager, or if the imager is in manual
trigger mode. Once the imager has timed out, you can activate the imager either by
pressing the trigger or using a serial trigger command. After scanning the Read Time-Out bar code, set the time-out duration (from 0-300,000 milliseconds)
by scanning digits from the inside back cover, then scanning Save . Default = 0 (infinite, or no time-out).
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.
Low Power Time-Out Timer
Scan the Low Power Time-Out bar code to change the time-out duration (in seconds). Then scan the time-out duration (from 0-300 seconds) from the inside
back cover, and Save . Default = 120 seconds.
If the unit remains idle during the low power time-out interval, the unit goes into low power mode. Whenever the trigger is enabled, the low power time-out
timer is reset.
Presentation Mode
This programs the imager to work in Presentation mode. The LEDs are either off or at the lowest power for ambient conditions until a bar code is presented
to the imager. Then the LEDs turn on automatically to read the code. Presentation Mode uses ambient light to detect the bar codes. If the light level in the
room is not high enough, Presentation Mode may not work properly.
