External Triggering and Trigger Modes
If you are using external triggering, you can use any of the following methods to trigger your DataMan 150 reader:
1.
Press the Trigger button ( ) on the reader.
2. Send a pulse on Input-0 line.
3. Send a serial trigger command over the serial line. (You must use RS-232 or USB communications type.)
4.
Click the Trigger button ( ) or press <Ctrl>-T in DataMan Setup Tool.
DataMan 150 supports a variety of trigger modes:
l Single: Acquires a single image and attempts to decode any symbol it contains or more than one symbol in cases
where multicode is enabled. The reader relies on an external trigger source.
l Presentation: Repeatedly scans for a symbol and decodes it whenever one is detected. The reader relies on an
internal timing mechanism to acquire images.
l Manual (default): Begins acquiring images when you press the trigger button on the reader or the discrete trigger
input is activated, and continues acquiring images until a symbol is found and decoded or you release the button
or the discrete trigger input is deactivated.
l Burst: Performs multiple image acquisitions based on an external trigger and decodes one or multiple symbols
appearing in the sequence of images.
l Self: Similar to Presentation mode in that the reader perpetually scans for symbols and decodes them each time
one is detected. Unlike Presentation mode, however, Self mode supports multicode results and a decode attempt
occurs with every image. The main difference between Self and Presentation is the fixed and exact interval for
image acquisitions in Self.
l Continuous: Begins acquiring images based on a single external trigger and continues to acquire images until a
symbol is found and decoded, or until multiple images containing as many codes as specified in multicode mode
are located, or until the trigger is released.
S models do not have Burst and Continuous trigger types.
