NEXUS DSP & Controller Card XTI
XTI provides serial interfaces in NEXUS whose data is transmitted transparently, independent of audio signals. Far away devices can be interconnected via the network and even switched between different ports and boards via the matrix. In addition, other board types, such as HDSDI boards, can be used to access their serial data from anywhere within NEXUS. MIDI and LTC can be linked to the control of STAGETEC mixing consoles via XTI.
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.
NEXUS – XTI – Features:
Galvanic isolation of inputs and outputs The interfaces of the XTI are galvanically isolated.
Level adjustment when converting different signals The levels of signals are adapted, for example, when converting an RS 232 into an RS 422 signal.
Bidirectional transparent transmission Data streams coming from one XTI board can be routed over a virtual cable to any other board on the NEXUS network.
NEXUS – XTI – Use cases:
Machine control via MMC MIDI Machine Control (MMC) is a widely used and easy-to-use solution to synchronize different devices to the same timeline, as required when working with DAWs or other playback systems, and the XTI card allows the MIDI protocol to be routed and distributed across the entire NEXUS network. With functions such as Play, Stop and Locate, a device control with common hardware and software can be set up very quickly by sending transport and control messages.
Distribute lighting control with NEXUS XTI makes additional cabling work for lighting installations unnecessary: instead of one or more electrical cables, the lines of the NEXUS audio and control network are used without any further effort. With the help of the transparent transmission module, DMX control data can be fed into a base device at any point, output and, thanks to fiber optic technology, protected against interference on its way to its destination. To save space and leave the interfaces open for the configuration of different formats, the connections of the XTI card are designed as 15-pin D-Sub sockets and can of course guarantee an effortless connection with a preassembled adapter cable.
