DC IN/SYNC Terminal

-The odd fields are low and the even fields are high for the pin 1 field index output.

-The pin 5 image signal is provided for auto-iris use so it cannot be con- nected to a monitor.

-The dc voltage output from pin 6 is the same as the input voltage.

2.2.8DC IN/SYNC Terminal

This terminal supplies the +12 V power, outputs the image from the camera module, and inputs/outputs sync signals, through cable connector HR10A±10P±12S. Table 2±7 lists the terminal pins, signals, and levels.
