External Input Details
•
Opto-coupled (2.4V to 24V) with internal current limit.
•
Selectable input trigger threshold levels for TTL, 12V, and 24V signal inputs (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
•
Differential signal drivers cannot be used due to the shared input common
