10.4.3 External-Gated Mode
External - Gated mode is similar to Continuous mode. While an external trigger input signal is active, the sensor continues
to capture images and run barcode scans until a successful Read occurs or until the External Trigger input signal becomes
inactive. The External - Gated mode uses the Scan Time Limit parameter (Main Menu > Inspection > Barcode > Scan Time
Limit) to limit the amount of time the sensor attempts to decode barcodes on an image.
Note: A No Read condition will not occur in External - Gated mode while the external trigger is active.
10.4.4 Industrial Ethernet Only
When the Industrial Ethernet communication channel is enabled, triggers can be received from the modes listed in this
manual. Triggers through Industrial Ethernet will not be executed if the selected Trigger Mode is Continuous Scan. To
receive triggers only through the Industrial Ethernet channel, select Industrial Ethernet Only.
10.4.5 Command Mode
In Command mode, the sensor captures images when Trigger commands are received. The various trigger command
modes can also be set through a command channel. For specific commands, refer to
(p. 70). The
commands can come from either Serial I/O or Ethernet I/O.
10.5 Focus
Main Menu > Imager > Focus
The Focus Number displayed at the bottom of this screen is used to fine-tune image focus. Loosen the lock on the lens
cover, turn the focus ring on the iVu BCR until the Focus Number peaks (or the image appears sharp), then lock the focus
ring.
Note: For the Focus Number to work, the iVu BCR must be triggering and the images must be similar
over time.
