System Network Considerations

Control Computer

Biamp Canvas software is designed to be installed on a control computer in a client facility. The computer must have a 100 BaseT Network Interface Card (NIC) installed, and the computer must be connected to a network that has access to the Tesira servers' Ethernet control ports.

The computer must have an IP configuration (IP address, subnet mask, default gateway, and DNS servers) that allows it to communicate with the IP address(es) of the Tesira server(s).

Control Network

The Control Network is used for communications between Tesira devices, as well as communication from Tesira servers to computers running Tesira software. The Control Network connections on a Tesira server reside on its SNC-1 or SNC-2 card.

Server-class devices

Tesira server-class devices are made up of SERVER, SERVER-IO and TesiraFORTÉ devices.

The Control Network port is a Gigabit network port, and is compatible with 10Mbit/s, 100Mbit/s, and Gigabit networks.

Control Network interfaces are assigned both an IP address and a hostname.

Tesira servers are configured by default with a unique hostname derived from a combination of the device type and serial number. Tesira servers are not configured by default with a default IP address, instead they are set to obtain an IP address automatically from a DHCP server. The hostname and IP address of a Tesira server can be modified via Tesira software.

Control Networks can span across subnets, but doing so requires the use of either an external DNS server to resolve hostnames to IP addresses, or the use of a Host Table. When a Host Table is used, server IP addresses must be assigned statically to ensure the IP address does not change. For more information, consult the Help system in Tesira software.

Expander-class devices

Audio Expander-class devices (EX-AEC, EX-IN, EX-OUT, EX-IO, EX-MOD) have a single network port, which often shares responsibility for both AVB and Control Network communications. For this reason, Expander devices must be able to access both the Control Network and the AVB Network.

EX-LOGIC and TEC-1 devices have a single network port which shares the Control Network communications so these devices will require access to the Control Network Only.
