Linea HS Multifield Camera
Using the GPIO controls the camera can be set up to strobe a light source effectively giving
exposure control.

Figure 14 Strobe Timing
The camera logic enables simplified control of external, pulsed light sources to assure reliable
timing association.
For this purpose, the trigger signal received from the system is managed by the camera to trigger
sensor response and data processing. In addition, an Exposure Active signal is generated and can
be supplied to any of the GPIO outputs. This allows triggering or timing external light sources.
Each output line can be programmed against the basic logic and relative to each other through the
ExposureDelay feature.
The following diagram illustrates the logical control signal flow in the Linea-ML, Linea-HM and
Linea-FM camera family.
The outputLineSource, outputLinePulseDuration, outputLinePulseDelay, and LineInvert features
allow the user to control a strobed light source in order to coordinate with the sensor exposure.
