Chapter 2 System Components Trigger Signal Requirements: Logic Low: 0 to 4.5 Vdc Logic High: 11 to 30 Vdc Current Input: 20ma (typical) Trigger Delay: 3usec (Minimum) Trigger Pulse Width: 2usec (Minimum) DebounceHigh: 0 to 5 usecs (User-Defined) DebounceLow: 0 to 5 usecs (User-Defined) Built-In Strobe Output The Visionscape GigE cameras incorporate an output for a strobe signal that is coordinated with image acquisition. Figure 2–7 shows the output opto wiring (Strobe ) for isolated outputs. FIGURE 2–7. Output Opto Wiring (Flash) for Isolated Inputs Flash Output Signal Response: Logic Low: 0 to 4.5 Vdc Logic High: 5 to 30 Vdc. (24Vdc @ 16ma recommended) Flash Delay: 2usec (typical) Note:
