The communication card:
»
has two switches (2 LAN 10/100/1000 ports), system (for VAS communication) and for remote connections (disconnected
during re-ghting) (1 LAN/WAN 10/100 port – congurable working mode),
» is equipped with VAS switch with AVB support,
» allows 1Gb/s transmission speed and has optical-ber interface (2 connectors for SFP modules),
» supports TCP/UDP/PTP/DHCP protocols,
» assigns IP addresses dynamically,
» thanks to replaceable libraries, RS485 port (ModBus) allows implementation of other protocols,
» has PoE feature,
»
can support two logic inputs or two relay outputs (every channels is congured on a case-by-case basis, and by default, both
are set as logic inputs) relay outputs NC/NO,
» in CPU-OFF mode. It transmits audio data via independent protocol,
» in the future it will allow using network infrastructure for other Audio-Video purposes.
To connect communication cards and reman microphone via an optical cable, it is required to use highly-reliable low power
consumption SFP 1,25Gbps optical modules.
SFP modules operate with single or multiple-mode optical bers sending information with up to 1,25Gbps. They transmit data
through optical ber pairs (duplex). Both SC and LC connectors can be used, the unit also supports digital optical monitoring (DOM).
