I/O Lines Usage
Input Lines
The input-capable I/O lines (DIN, TTLIO, IN) can be used as:
- General purpose input: An input signal whose state can be read or monitored by the host application.
- Motion encoder input: A pair of input signals delivered by a quadrature motion encoder and used for triggering the acquisition from the camera.
- Trigger input: An input signal used to trigger the acquisition from the camera.
Output Lines
The output-capable I/O lines (TTLIO, IOUT) can be used as:
- General purpose output: An output signal whose state can be set by the host application.
- Strobe output: An output signal usually used to control a strobe light, in synchronization with the camera.
- Camera trigger output (only available on TTLIO): An output signal generated by the Coaxlink card and used to trigger the camera.
