Network Connection

On the rear of the AVB Tool, a ruggetized RJ45 connector labeled NETWORK provides ethernet connectivity. The supported link speed is 1 Gb/s for AVB.

A green LED (left, LINK) signals a successful link. A yellow LED (right, ACT) signals network traffic (blinking).

Both straight and crossover cables can be used (Auto MDI-X). Cable lengths of up to 100m are supported when using Cat 5e or higher classification.

The network port is used to send and receive:
  • up to eight AVB audio streams when connected to AVB switches and endpoints,

  • remote status/control with AVDECC, and

  • remote status/control with HTTP over IP routed networks.

The current link state is also shown on the display of the AVB Tool.

A network port icon in the menu reveals the following states:
