Camera interfaces
Out 2– non-isolated
Out 2 signal is not electrically isolated and can be used when environmental
electrical noise is inconsequential and faster trigger response is required. Use
Signal GND to complete the external circuit. The output signal is a low voltage
TTL, maximum 3.3 V. Not suitable for driving loads in excess of 24 mA. See
Video iris user circuit example
for more wiring information.
Signal ground
Signal Ground must be connected to the user’s external circuit ground if In 2
or Out 2 is to be used, or if the RS232 port is to be used. Note that Signal
Ground is common with Camera GND; however, it is good practice to provide
a separate ground connection for power and signal.
Video iris
This signal can be used to drive the video input of a video iris lens. See
section for wiring information.
Reserved
These signals are reserved for future use and should be left disconnected.
