Network Connection

On the rear of the M-1620 Pro, two RJ45 connectors labeled NETWORK PRI and SEC provide ethernet connectivity. The supported link speed is 1 Gb/s for AVB.

A yellow LED (left, LINK) signals a successful link. A green 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 ports are used to send and receive:

  • up to eight AVB audio streams when connected to AVB switches and endpoints,

  • one CRF clock stream,

  • remote status/control with ATDECC, and

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

The current link state is also shown on the display of the M-1620 Pro. Two network port icons in the menu reveal the following states:
