The Master Clocks can be configured to generate a master clock signal for cameras. These are outputs and the frequency can range from 500 kHz to 50MHz.
The RTSI bus is simply a bus that allows you to route trigger and timing signals across to synchronize multiple devices. This bus can be either input or output.

Both master clocks are outputs? According to NI tech support, master clock 1 is generally used as an input to slave the card to a clock generated by a camera. Can master clock 0 be configured this way (as an input)?
