What is the function of 30VDC in the system?

Explanation:
The 30V DC is used to bias the line so it stays in a defined, non-floating state. This small constant voltage “wets” the line, ensuring a reliable reference for signaling and preventing the line from drifting into an undefined condition when devices are connected or disconnected. It’s not meant to power the camera, nor to activate the EVS, nor to transfer data—the DC bias serves to keep the transmission path ready and stable for proper operation.
