Host Notify Mode
Host Notify Mode bypasses the decoder and notifies the host that there has been a hardware
trigger pull. When in Host Notify Mode, it is up to the host to initiate an Image Snap and/or an
Image Ship command (see Imaging Commands beginning on page 95). It is also up to the host to
switch to another trigger mode.
Scan Stand Mode
When a unit is in Scan Stand mode, it remains idle as long as it sees the Scan Stand symbol.
(See
Scan Stand Symbol that follows.) When a different code is presented, the Imager is
triggered to read the new code.
Note: The imager automatically adjusts the illumination LEDs to the lowest light level possible to
maintain a good lock on the Scan Stand symbol. When a symbol is presented, the imager‟s light
levels adjust to the saved setting (see Hands Free Time-Out on page 34).
Scan Stand Symbol
When a unit is in Scan Stand mode, the LEDs shine at the Scan Stand symbol on the base of the
stand which tells it to remain idle. When the Scan Stand symbol is covered, the imager turns the
LEDs on at the configured power level (Default High) and attempts to find and decode bar codes
in its field of view. The Scan Stand Symbol is a function code 3 using Code 128 symbology.
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.
