Mako U Technical Manual V1.1.3
Input levels
The GPIOs can be connected directly to the system for voltages up to 24 VDC.
An external resistor is not necessary.
Input timing delay and minimum pulse width
The hardware input delay is 10 to 70 ns, it is part of the entire trigger latency.
For trigger latency values, see
The
minimum pulse width
for Mako U cameras is:
Test conditions
The input signal was driven with 3.3 VDC and no external additional serial resistor.
