Genie Monochrome Series-GigE Vision Camera 
Operational Reference    45 
External Trigger Level-controlled Exposure 
•  Also known as “Pulse Width Control” exposure. See the timing diagram below.  
•  The external trigger edge initiates the exposure process. The active external trigger edge can be selected as 
either the low-high or high-low transition.  
•  No delay from active trigger edge to start of exposure.  
•  Exposure is stopped by the opposite edge on the trigger signal. Therefore the exposure time is defined by the 
trigger pulse duration.  
•  Supports 
 trigger timing only.
