NEXUS – XTI – The concept:

XTI transmission cards allow external serial data to be forwarded and distributed over the NEXUS network. Similar to the routing of audio signals, these data connections can even be switched back and forth between different devices via the matrix. In addition to this transparent handling of data connections, i.e. independent of the NEXUS system, there are numerous interesting, combined applications. This allows the serial data of other NEXUS boards to be sent to and accessed from any XTI boards in the system. The other way around is of course also possible. This function for transmitting metadata to the XSDI/XHDI video embedder/deembedder boards is of particular interest.

Other applications include STAGETEC's mixing consoles that process MIDI and Longitudinal Time Code (LTC). These signals can be fed into the network via XTI cards, forwarded and transferred directly to the console. A special feature is the transmission of a control signal via a MADI connection. The data of an XTI port can be embedded in a MADI audio channel and thus transferred beyond a single NEXUS system.

XTI cards are available in two designs: with two serial ports with 4 HP width and with four ports on 8 HP. To cover a wide range of applications, the XTI board transmits the common control protocols such as RS232/422/485, MIDI, DMX or the synchronous format LTC. In many installation applications, the possibility of using different electrical interfaces on both sides of a connection is of great interest as long as the connected devices use the same protocol. XTI cards can also be used as format converters for serial interfaces.
