ProtocolVersion

public struct ProtocolVersion : Serializable

There are two version numbers in ATEM world: One for the ATEM Software Control application (for instance version 6.0) which is what people usually refers to and one for the firmware which is often updated with the PC/Mac application versions (for instance 2.15). The latter version number is what “_ver” gives you and a number you can not find anywhere in the application to our knowledge.
