Overview
Host Management Interface (HMI) - The hardware (8-bit bi-directional parallel interface)
and protocol for accessing MI variables locally. The HMI is described in detail in the
CS4961xx/CS1810xx Hardware Manual and CM-1 Hardware Manual.
Management Interface (MI) - The set of variables used to control and monitor the
CobraNet interface. MI variables are accessible both locally through the
Host
Management Interface (HMI) and over the network using Simple Network Management
Protocol (SNMP). MI variables are described in detail in
Interface Variable Reference" on page 28
Packet Bridge - A function provided by the CobraNet protocol which allows a CobraNet
interface to send and receive raw Ethernet packets over the same Ethernet media used
for audio transmission.
Performer - A CobraNet interface which receives its transmission permissions and
master clock from a conductor. In the event a conductor fails, the CobraNet protocol will
automatically promote a performer to become the new conductor.
Receiver - A logical entity within the CobraNet interface capable of receiving one Bundle.
Serial Bridge - A function provided by the CobraNet protocol which allows a CobraNet
interface to send and receive asynchronous (i.e. RS-232) data over the same Ethernet
media used for audio transmission.
Transmitter - A logical entity within the CobraNet interface capable of transmitting one
Bundle.
