Opto-Coupled I/O Lines
The opto-coupled I/O lines of your Basler camera are
preconfigured to operate either as input or output lines.
Characteristics
- Opto-coupled I/O lines are preconfigured to operate as input or
output. You can't change the line mode
of opto-coupled lines.
- If your camera has opto-coupled lines, one of them is always a
dedicated input line and another a dedicated output line.
- Opto-coupled I/O lines have the advantage of being considerably
more robust against EMI
than GPIO lines.
- Opto-coupled I/O lines have longer propagation
delays (response times) compared to GPIO
lines.
- The minimum required pulse width for input triggers is longer compared
to GPIO lines.
Make sure to provide sufficient time for the camera's input circuit
to react. For most cases, a pulse width of 100 μs should be long enough.
