Genie HM-HC Series-GigE Vision Camera  Operational Reference  49 
Programmable Reset Mode Exposure Timing 
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. 
  There is a fixed 100μs delay from active trigger edge to start of exposure. Note that the user must also account 
for the input opto-coupler electrical specifications (see "External Inputs" on page 109) and any
 programmed 
input trigger debouncing period. 
  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 52 t
rigger timing only.
