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.
