There are four jumpers that are useful for configuration.
Two are sets of three pads labeled 12-5. The one closest to the
IN pad sets the camera voltage. Shorting the two pads on the 12
side sends 12V to the camera, and the two closest to the 5 side
sends 5V to the camera. The one nearest the OUT pad is the same for
the VTX.
On the same side, there's an GND jumper which configures a common
ground for the OSD itself and the video.
On the other side, there's one labeled +V which jumps the 5V input
pins so you can have a single 5V input that is used for both outputs
and operating the OSD itself.
