External Input Details
• Opto-coupled with internal current limit.
•
Single input trigger threshold level
(TTL standard: <0.8V=Logical LOW, >2.4V=Logical HIGH. See lineDetectionLevel feature).
•
Used as trigger acquisition event, counter or timestamp event, or integration control.
• User programmable debounce time from 0 to 255µs in 1µs steps.
•
Source signal requirements:
•
Single-ended driver meeting TTL, 12V, or 24V standards (see table below)
•
If using a differential signal driver, only one input can be used due to the shared input
common (see details below)
