Signal Generator for System-Wide Use
This central module provides a systemwide test signal, which consists of a sine tone with adjustable level and frequency, a white or pink noise.
NEXUS Logic Control as Integrated Media Control
NEXUS Logic Control can be used to program the simplest to the most complex interactions and automations. Each Base Device has a stand-alone logic unit that communicates with the entire NEXUS system. For example, the status of crosspoints can be evaluated or the level of specific signals can be monitored. In combination with other NEXUS boards, certain additional functions are available. Thus, relay inputs can be queried and set with the XRI card.
In conjunction with complex conditions, Logic Control can trigger virtually any control functions throughout the NEXUS network, such as switching relay contacts, setting crosspoints, setting levels or even controlling mixer functions. This can also be used, for example, to integrate the NEXUS system into comprehensive external disaster systems or to trigger alarms.
Extensive Internal and External Synchronization Options
The NEXUS system can be synchronized and the internal clock can be output via the integrated word clock inputs and outputs. The board can also synchronize the NEXUS system to any digital input. A sync hierarchy can be created so that, in the event of a source failure, an uninterrupted and inaudible fade over to the next sync source.
System State Fail-Safe Memory
All volatile data is immediately stored on a battery-buffered SRAM memory and is retained in the event of a power failure or switch-off. This means that the system boots immediately to the last operating state and is ready for use again within seconds.
Determination of Level Data for Level Indication
The level measurement data converge on the XCPU card and can be visualized via the operating program.
XDEM Expansion Card with Serial Interfaces Optionally Available
The XDEM module is not a stand-alone plug-in board but an extension for the NEXUS boards XDED, XDEE, XHDI and XCPU. It provides two additional RS232- or RS422-compliant 9-pin D-Sub interfaces, which can be used to access the metadata ports of these boards. It is a simple, direct solution to pass metadata to or read metadata from these boards when none of the other higher-level solutions available with the NEXUS board are used.
The module has two ports that can be used in different constellations: One port each together with a Dolby module of an XDED Dual card or with the Dolby module of two XDED Single cards. Or one port each with the Dolby module of up to two XDEE cards. Or in combination with an XHDI card one port with the de-embedder of the card and the other port with its embedder. Alternatively as additional serial interfaces of the XCPU board in the formats RS232 and RS422.
