SCUE-NET is a communication card consists of two independent 1 GB network switches. Network switch no. 1 is destined solely for transition of data connected with the basic functionality of the NANOVES system, i.e. working of the emergency sound system and AVB operation whereas network switch no. 2 is used for remote connections. This card operates TCP/UDP/PTP/DHCP protocols and assures CPU-OFF based audio data exchange. In addition the card has an RS485 port enabling implementation and integration of the NANOVES system with any other systems, e.g. Fire Alarm System, by means of exchangeable libraries with protocol descriptions. Another functionality is a POE splitter for providing power to, among others, fireman microphones.
