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 "
Reset Mode" on page 47 trigger timing only.
