The XRT board is a super routing matrix for base devices that can switch and distribute signals independently. Six of the twelve SFP ports support high-speed connections, each of which can transmit 2,048 audio channels.
An XCPU card is the core of every base unit. It has an organizational and monitoring function and provides interfaces for user operation. External control systems can also access the system via the XCPU cards.
The XFOC card allows NEXUS base devices to be connected via fiber optic cables. This makes it possible to create complex networks whose topology has virtually no limits.
The XSYNC board makes it possible to synchronize a NEXUS network with external video sources. This ensures that each video frame is always assigned exactly the same number of audio samples.
