Connecting the Hardware
MegaCOMMS
Cadac
’s proprietary MegaCOMMS hi-speed data protocol is used to interconnect the network bridge to
the console. The CM-MD64 MADI network bridge and the console have four BNC sockets to provide
the main system data interconnection, labelled OUT (TX) A, IN (RX) A and OUT (TX) B, IN (RX) B:
1: The CM-MD64 has two pairs of MegaCOMMS ports on BNC connectors
Cadac consoles have two pairs of BNC sockets, plus two optical ports for MegaCOMMS:
The two paths, A and B, carry identical and synchronous data, and can be used in various ways,
depending on whether system redundancy is required. Providing a redundant path gives greater system
robustness, as the CM-MD64 will automatically switch its comms to Path B if communication is lost on
Path A, such as might occur if a cable is damaged. Note that the CM-MD64 is fully functional in all
respects if only one coax TX / RX or optical path is connected.

duplex optical LC ports
