CobraNet audio channel:

In CobraNet terminology, an audio channel is one 48 kHz digital audio signal with a 16, 20, or 24-bit resolution.

CobraNet primary/secondary ports:

CobraNet interfaces feature built-in redundancy, with primary and secondary ports for connection to primary and secondary networks. If an unrecoverable fault should occur on the primary network, CobraNet automatically switches to the secondary network, providing uninterrupted operation. Both ports are transformer-isolated and fully comply with the IEEE 802.3 standard.

Ethernet:

The most widely implemented network protocol. The first implementation, 10Base-T, supports data transfer rates of 10 Mbps. The next implementation, 100Base-T (or Fast Ethernet) supports 100 Mbps. The newest version, Gigabit Ethernet, supports transfer rates of 1,000 Mbps (i.e., 1 gigabit).

Fast Ethernet:

Also known as 100Base-T, the Ethernet standard that supports data transfer rates of 100 Mbps. CobraNet runs on Fast Ethernet networks.

LAN (Local Area Network):

A network that exists in the same building or group of buildings. CobraNet is a LAN technology. See also WAN.

RJ45 connector:

The type of connector used to connect 10 Base-T, 100 Base-T, and 1000 Base-T Ethernet devices.

RS-232:

A serial interface for connecting serial devices, offering a transmission distance of approximately 15 meters, typically using 9-pin or 25-pin D-sub connectors.

Switch:

Switch know the network address of each device on the network and automatically route network traffic accordingly, so each device receives only data addressed to it.

COBRANET device

A device designed t o receive and transmit audio data using COBRANET technology.
