CobraNet Network

The Tesira SCM-1 card allows server-class devices to share digital audio with CobraNet-enabled devices.  Each SCM-1 card can transmit up to 32 channels and receive up to 32 channels of audio. Each set of up to 32 channels must be grouped into no more than 16 bundles, and each bundle is identified by a unique bundle number.

Bundle Size	Latency
	5.33m			2.33ms			1.33ms
	RX	TX	RX/TX	RX	TX	RX/TX	RX	TX	RX/TX
8	32	32	32/32	32	32	32/32	32	32	32/32
7	32	32	32/32	32	32	32/32	32	32	28/28
6	32	32	32/32	32	32	32/32	32	32	30/24 or 24/30
5	32	32	32/32	32	32	32/32	32	32	25/25
4	32	32	32/32	32	32	32/32	32	32	24/20 or 20/28
3	32	32	32/32	32	32	32/32	32	32	21/15 or 18/21
2	32	32	32/32	32	32	28/28	24	32	14/14
1	16	16	16/16	16	16	16/16	13	16	8/8

 

CobraNet networks must always be separate from the Control Network AVB Network and Dante Network. This may be accomplished either physically, by using separate network switches; or logically, by assigning CobraNet links to a separate virtual LAN (VLAN).

Conductor Priority

CobraNet devices have a mechanism for electing a device to act as the master synchronization clock for the network, also known as the conductor. One CobraNet device must be elected as the CobraNet conductor.

Primary and Secondary Connection

The secondary port found on the SCM-1 card is not to be used for daisy chaining – this is for CobraNet redundancy only.
