3.14. 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 network traffic (blinking). A yellow LED (right,

ACT

) signals a successful

link.

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 reveal the following states:

Icon

Description

No link - cable not connected

Negotiating link with other endpoint

Link with speed of 100 MBit/s (not
supported for audio streams)

Successful link with speed of 1 GBit/s

3.15. Word Clock

Word clock can be sent and received via 75

Ω

coaxial cabling at the corresponding BNC connectors. The

cable length should not exceed 100 m (330 ft).
