    7.Features The frame grabber supports a total of 4 Timers. When setting up, you should first select the Timer to be configured through TimerSelector, with a range of Timer0 ~ Timer3. During the timer output disabled period, the timer output remains at a low level and is not controlled by the timer output invert.

    7.Features Configuration Method Choose the appropriate trigger source from TimerTriggerSource, set the TimerTriggerActivation to one of the three options of AnyEdge, FallingEdge, or RisingEdge, and then set the TimerTriggerDivider’s value as your need. Usage Instruction Eg: Expect Line0 to generate a Timer output after receiving 5 edges. Set TimerTriggerSource to Line0, TimerTriggerActivation to AnyEdge, and TimerTriggerDivider to 5, and then refer to 7.7.1.Timer Output Format for Timer output waveform’s configuration.

    7.Features  In this mode, all overlapping trigger signals are discarded and have no impact on the Timer output.  Latch The first overlapped trigger signal in this mode will be saved, and any subsequent overlapped signals generated by the Timer during the output process will be discarded. A new Timer output will immediately initiate at the end of the Timer output.

    7.Features 7.7.10. TimerTriggerSource Timers can be triggered through various triggering sources, and users can specify the triggering source of the current Timer through TimerTriggerSource. Currently, it supports different Line options, Continuous, RotaryEncoder0, RotaryEncoder1, Software, Timer1~Timer3. Among them, different Line options indicates support triggering through I/O’s input signals, Timer1~Timer3 indicates support triggering through Timer’s output signals, Continuous indicates Timer continuous free output, RotaryEncoder0 and RotaryEncoder1 indicates support triggering through pulse signals output by the encoder decoding module.
