Q-SYS Network Interfaces

Q-SYS provides many network-related functions across multiple types of Network Interface Cards (NICs). Q-SYS Core processors, peripherals, and some I/O cards include network interfaces.

Q-SYS Core Network Interfaces

Q-SYS Core processors include at least two network interfaces.

• LAN A: Included on all Q-SYS Core processors, LAN A is required for use with the primary Q-LAN network. (If the Q-LAN network is not redundant, LAN A must be used for Q-LAN.) LAN A can also be used for other functionality.
• LAN B: Included on all Q-SYS Core processors, LAN B is required for use with the secondary Q-LAN network. It can also be used for other functionality.
• AUX LAN / AUX A, B: Except for the Q-SYS Core 110f, Q-SYS Core processors include one or more AUX ports that can be used for non-time-sensitive networking applications.

Q-SYS Core Network Interface Functions

The following table shows some key Q-SYS network functions and their associated network interfaces. For a detailed list of the services, protocols, and ports used by Q-SYS, see Q-SYS Network Services and Protocols.

Note: Use Q-SYS Core Manager to disable many network-related functions and protocols on a per-adapter level. See Q-SYS Core Manager > Network Services.

Q-SYS Peripheral Network Interfaces

Some Q-SYS peripherals have both LAN A and LAN B interfaces. Connect each interface to the network corresponding to the same interface on the Q-SYS Core processor.

Note: Q-SYS peripherals cannot be placed on LAN A and LAN B when there is only a single network.

Q-SYS I/O Card Network Interfaces

Q-SYS I/O cards with network interfaces include the Dante™ audio bridge card (CDN64), AVB bridge card (CAN32), and CobraNet™ digital input/output card (CCN32). The network interfaces on those cards are used exclusively for those purposes.

Note: Although the AES/EBU digital input card (CIAES-16) includes RJ-45 connectors, it does not support Ethernet in any context.
