Prosilica GT Technical Manual V3.2.0
In 1 (Non-isolated)
In 1
is not electrically isolated and can be used when environmental noise is
insignificant and faster trigger response is required. The required trigger signal is
low voltage TTL 3.3 volts. Tie trigger ground to Camera GND to complete the
trigger circuit.
In 2 (Opto-isolated)
In 2
is optically isolated and can be used in electrically noisy environments to
prevent false trigger events. Tie trigger ground to Isolated IO GND to complete the
trigger circuit. Compared to the non-isolated trigger,
In 2
has a longer propagation
time. It can be driven from 5 to 24 volts with a minimum current source of 5 mA.
NOTICE
Power caution
Exceeding 5.1 volts on
In 1
can permanently damage the camera.
