Benefits & Features

• Bridges SymLink hardware to CobraNet.
• Transmits and receives up to 32 channels of audio and SymNet control data over a CobraNet network.
• Ethernet control interface for other SymLink hardware.
• 64 channels of SymLink busing.
• Two RS-232 ports and one RS-485 port; primary and secondary CobraNet ports; Transmit and Receive SymLink ports.

Product Details

CobraLink translates between SymLink™ and CobraNet® buss technologies. This software-controlled-hardware scheme allows system designers an enormous amount of flexibility by providing:

• Broadcast or multicast bussing in incremental send or return bundles
• Up to eight channel groups
• Selectable latency options and bit-depth options
• Sharing of digital audio between SymLink rings, Express units, and third-party CobraNet-compatible hardware including amplifiers and powered speaker systems.
• A maximum of 31 CobraLink units, with associated SymLink rings, can be designated in a single SymNet system design.
• 64 channels (32 transmit, 32 receive) of Cirrus Logic CobraNet protocol for audio over Ethernet.
• CobraNet-to-SymLink routing, configured by SymNet Designer software.
• Direct network addressability from SymNet Designer over Ethernet.
