Page 13: Madi Bridge Overview
MADI Bridge Overview The Cadac CM-MD64 is a 1U, MADI to MegaCOMMS audio network bridge, enabling MADI units to be incorporated within a MegaCOMMS audio network. The unit supports up to 64 bi-directional connections to map between MegaCOMMS ports and a MADI network. -
Page 14: Megacomms: Data Protocol
MegaCOMMS: Data Protocol Communication between the unit and the console is via a proprietary Cadac high speed protocol called MegaCOMMS. The protocol uses high-speed 75 ohm coaxial cable terminated in BNC connectors or depending on the unit, via fibre optic cable using the duplex optical LC ports. -
