Each LVTTL signal of the I/O Port has two modes of operation. The signal may be used as a general purpose and user-
defined I/O pin, or it may be configured to perform a predefined/fixed-function operation. After initialization, the I/O Port
defaults to having the signals set as user-defined.
The ICamera2 property, IoPortAssignment, is used to control whether each signal is set to the user- defined or
predetermined setting. For user-defined signals, the IoPortDirection property determines whether the signal is an input or
output. Please refer to the documentation for these properties for additional details regarding their operation.
The fixed function descriptions of each pin are as follows:
Pin 1 – Trigger Input – Used to initiate triggered exposures (both single exposures and sequences). When the
CameraMode property is set to Apn_CameraMode_ExternalTrigger, the ICamera2 interface object will automatically
enable this pin to be used as an input for an external trigger signal. Applications should still call the Expose method
to put the camera system into a state where it is waiting for the trigger to arrive. Triggered exposures use the duration
parameter that is specified in the Expose method to program the camera’s exposure timer. Internally, the Apogee camera
will automatically continue flushing the sensor until the triggered exposure begins.
Ethernet
Enables connection and control of camera via an Ethernet connection, for example where the control PC cannot be
located close to the camera. The built-in web server supports operation at up to 2 Mhz over longer distances.
