The NEXUS intelligent generic communication-interface board supplements the functionality of a NEXUS audio network with control functions: The XCI board allows external devices to be remote-controlled and control protocols queried. Suggested applications include the provision of connectivity to operating panels for controlling NEXUS functions or remote-controlling peripheral units such as power amplifiers or audio recorders. Other protocols and/or control functions for other devices can be implemented in addition to the pre-programmed standard functions. XCI Communication-interface BoardAll control information required by the XCI board is transferred via the fibre-optic lines of the NEXUS network, so no additional cabling is necessary. The control functionality is fully integrated into NEXUS, and the board can therefore be operated from anywhere on the network.
The XCI board is shipped with a project-specific hardware configuration and various software modules. To fulfil the requirements imposed by its universal character, the board is equipped with a dedicated processor, memory, and firmware. A buffer based on a lithium battery or an accumulator preserves the user data stored to the SRAM memory even when the operating voltage is not present for an extended time. Both the terminal pinout and the supported protocol are individually configured as required by the customer.
