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.

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