3.2.2 Trigger Input
The 1400 I/O Expansion Module provides inputs for triggering a connected In-Sight sensor
(T, TRIGGER-). When the expansion module is connected to a supported
In-Sight sensor, trigger input signals travel directly through the expansion module and are
optically isolated in the sensor. Trigger inputs are typically connected (directly or indirectly)
to a sensor (such as a photo-detector).
