Appendix D: Teklogix Imagers Applet
Required Applets
Psion Teklogix Omnii XT10 Hand-Held Computer User Manual D-5
The Teklogix Imagers applet is used to create, modify, delete, and activate imager settings.
The principal uses of the application are to decode bar codes and to capture images. This
imager services application is used for cameras and imagers to configure linear (1D),
stacked linear, matrix (true 2D) and postal bar codes. A
Demonstration Application is pro-
vided to demonstrate how the imager works. Refer to “Demo” on page 65 for details.
D.1 Required Applets
In order to configure imaging, the Manage Triggers applet must be present in the Control
Panel, along with the Teklogix Imagers applet.
D.2 Presets
There are two methods that can be used to configure an imager using the Teklogix Imagers
applet:
•
Use a predefined preset.
• Create a custom preset based on a predefined preset.
A preset is a group of exposure and image correction settings. Each preset configures the
imager for a specific purpose such as bar code decoding or image capture.
Presets also allow easier and faster configuration of the imager after power-on or resume
from suspend.
The predefined presets are generic and satisfy most user requirements. A custom preset can
be created for a specific user application, such as: include only specified bar codes, read
only a specified number of bar codes or for reading unusual media.
Every preset belongs to a preset type. The following preset types are available:
Note: The Teklogix Imagers icon is only displayed when the appropriate imager is
installed in your Omnii. If there is an imager installed but this icon is not present,
additional software (ICS) may need to be installed.
To enable a newly-installed imager, press and hold down the [FN] key and the
[ENTER/Power] key simultaneously for a minimum of three seconds.
Important: It is strongly recommended that a predefined preset is used
whenever possible. Each predefined preset contains a coherent
group of settings that are known to work together in the intended
environment. In almost all situations, at least one of the prede-
fined presets results in a satisfactory outcome.
