2-2-9 Configure Acquire Settings
Acquire settings allow you to set Exposure (signified by the sun icon) and Gain (signified by the dial
and right-pointing arrow icon) in real time. Clicking any of these settings will
cause a control to appear,
allowing you to modify that setting. Settings take effect immediately.
• Important: There are 4 levels of Gain in SXGA readers. Each level corresponds to 25 percentage
points, or one quarter turn of the Gain dial shown at left.
• Level 1 = 0 to 24%
• Level 2 = 25 to 49%
• Level 3 = 50 to 74%
• Level 4 = 75 to 100%
When Auto Photometry is enabled instead of Standard, Exposure and Gain are read-only. The A
shown on the sun and dial icons signifies that Auto Photometry is enabled. Auto
Photometry constantly
determines the best Exposure and Gain settings during each read cycle.
Autofocus can be enabled and disabled in the Image Area using the focus button in the Device
Control Toolbar, and can be configured in the Acquire section of the Setup view.
While in Continuous mode or Continuous Auto mode, the reader can enable or disable Autofocus
functionality, allowing it to refocus after a number of no reads. The focus button shows an A when
Autofocus is enabled. The focus distance is updated on the fly based on the latest refocus settings.
