The I/O ports are disabled at power-on, to disconnect any external load and user termination whose
power consumption may exceed the USB 3.2 Gen 1x1 standard requirements during the bus recognition
and enumeration phase. The I/O ports are automatically enabled at the end of the USB enumeration
phase.
4.0.1 Detecting I/O power
NECTA features a 24 V tolerant I/O interface. However, previous NECTA hardware releases tolerates
only 5 V signaling: for this reason, on each camerathis feature is specied on the label, in order to quickly
identify which model is compatible with 24 V signals.
