6.1.2.2 ABT-xNet_mini-1Gb communication card
The ABT-xNet_mini-1Gb is a downsized version of the previous ABT-xNet_mini-1Gb/WAN/RS communication card. As it’s
predecessor it consists of two independent 1 Gbit network switches.
The network switch no.1 is intended solely to transmit data related to basic AutroVoice miniVES system functions, that is perform-
ing tasks of alarm voice system and AVB support.
The network switch no. 2 is intended for remote connections. The card supports TCP/UDP/PTP/DHCP protocols and assures audio
data exchange in CPU-OFF mode via an innovative Autronica protocol. This card is not equipped with an RS485port but supports
PoE technology on one of the RJ45 ports to power e.g. fireman microphone.
Unlike the AutoVoice MULTIVES system in the AutroVoice miniVES devices the communication card also doubles as the main CPU
card. It is responsible for reproducing audio messages from the SD card and sharing them locally or globally while also performing
system and control functions.
The card is capable of reproducing 8 messages at a time and supports SD cards up to 32 GB for individual messages, as well
as event or defect logs or system update files.
