External Triggering and Trigger Modes

If you are using external triggering, you can use any of the following methods to trigger your DataMan 260 reader:

1. Press the Trigger button () on the reader.
2. Send a pulse on the I/O cable: Trigger + (orange or red), Trigger - (black).
3. Send a serial trigger command over the RS-232 or the Ethernet connection.
4. Click the Trigger button () or press <Ctrl>-T in DataMan Setup Tool.

DataMan 260 supports a variety of trigger modes:

• 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.
• Presentation: Repeatedly scans for a symbol and decodes it whenever one is detected. The reader relies on an internal timing mechanism to acquire images.
• 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.
• Burst: Performs multiple image acquisitions based on an external trigger and decodes one or multiple symbols appearing in the sequence of images.
• 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.
• 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.
