5.5 Digital Input / Output Control

The digital inputs and outputs of the twentynine 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 3.3 - Power and I/O-Interface.
Each physical line is configured separately and can be selected by the LineSelector property. The property
LineMode provides information if the currently selected line is an Input or Output . Table 35 describes all
available configuration properties.

5.5.1 Input Lines

The camera's input lines can be used to trigger an acquisition of the camera on external events. Figure 45
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 user defined
TriggerDelay increased by the fixed trigger latency caused by internal circuitry defines the start of the
triggered event.
