Digital Input
Each port has one optically isolated digital input that can act as a start trigger for the
camera. It also support debouncer and inverter features. The debouncer feature
identifies valid/invalid input signals on the basis of the minimum period of time for the
valid signal (i.e., the debouncer value). Thus, the circuit will respond only to those
signals that have a pulse width greater than the debouncer value.

Digital Output
Each camera port has two optically isolated digital outputs that support an inverter
feature. The outputs can be configured to operate in three different modes: user-pro-
grammable mode, pass mode, and counter mode.
User-Programmable Mode:
This mode allows you to program the state of the digital output line.
Pass Mode:
In this mode, the digital output signal is active whenever a valid digital input signal is
detected.
Counter Mode:
In this mode, the digital input signal acts as the trigger source. The falling or rising
edge can be set as the trigger event for the digital output to generate a pulse. The
delay time and pulse width are user-defined. The basic principle of counter mode is
exemplified as follows, with a timing chart depicting how the rising edge acts as a
trigger:
1.
A rising edge is detected in the input signal.
2.
When the delay time expires, the output signal switches to high.
3.
When the signal period expires, the output signal switches to low.
