Cognex DataMan 8700 - Field of View and Reading Distances

l
Manual (default): Pressing the trigger button on the reader starts image acquisition. The reader continues to acquire
images until thare is a detectable and decoded image or until the release of the trigger button.
l
Presentation: When motion is detected in front of the reader, the reader turns on and scans for a symbol. When no
motion is detected, the LEDaimer and the lights turn off. The reader relies on an internal timing mechanism to acquire
images.
