Trigg er Key
This drop-down list allows you to specify the source of the trigger events, such as the Soft
Scan, Left Scan, etc., for the trigger module selected.
Add Key
Only existing trigger sources are shown in the Source combo-box. To add a new source to
this list, tap on the Add Key button. A dialog will pop up and allow you to select the key-
board key to use as a trigger source.
Trigger-Press Type
You can enable either an Up/Down or Double Click response to a trigger press. Normally,
when a trigger (keyboard key, etc.) is pressed and released, a “trigger down” event is sent to
the “owner”—that is, the application receiving the trigger press information—followed by a
“trigger up”. If Double Click is chosen in this menu, when the trigger is pressed, released,
and then pressed again, a “double-click” event will have occurred. If a mapping with the
type Up/Down has also been configured for the same source, it will only receive the first set
of trigger events.
Note: It is possible to map the same source to different modules (trigger consumers)—for
example, to both the Imager and Non-Decoded Scanner. If so, both devices/opera-
tions will occur simultaneously. This is not recommended in most cases, especially
with devices such as Imagers or RFID Readers.
It is also possible to map different sources to the same module (trigger con-
sumer)—for example, two different trigger keys can be mapped to the RFID
File System.
