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 
Camera I/O non-isolated 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 RS-232 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 Video iris 
user circuit example section for wiring information.
Reserved
These signals are reserved for future use and should be left disconnected.
