4.6 Digital Input / Output Control

The digital inputs and outputs of the Giganetix series can be used to synchronize the camera with other
devices and cameras. The camera can be triggered on a rising or falling edge of the input trigger signal,
or trigger other devices on configurable events. The physical interface is provided via the General Purpose
Input and Output (GPIO) connector, described in 2.3.2 - Power and I/O-Interface.
Each physical line is configured separately and can be selected by the LineSelector property. The property
LineMode contains if the currently selected line is an Input or Output. Table 59 describes all available
configuration properties.

4.6.1 Input Lines

The camera's input lines can be used to trigger an acquisition of the camera on external events. The
assignment of the physical input lines as a frame or acquisition trigger is described in Chapter 4.5.2 -
Triggered Operation. Figure 100 shows the partial process of a complete image acquisition. The incoming
electrical signal of the external source is filtered by the LineDebouncer and raises the internal trigger signal
(if valid). The internal circuit adds a fixed trigger latency stated in the camera's specification (usually ∼ 2
to which the user defined TriggerDelay is added until the exposure is started.
