Product Features

  • Gives you data-rate buffering capabilities up to 10 Mbps—and at greater distances.


The V.11 LS from Black Box uses the V.11 balanced interface and data-rate buffering capabilities to bring 10-Mbps data broadcasting to your network.

Because the V.11 LS supports connections to eight receive-only devices simultaneously, it's perfect for continuously updated public data displays and distribution of continuous, noncritical data to multiple LANs, PCs, or printers.

What's more, the V.11 LS also has tandem DB15 connectors, so you can cascade it without losing user ports from a single data source. It continuously broadcasts receive data, receive timing, and a control signal from the data source on the eight output DB15 ports.

The balanced V.11 interface supports data transmissions at greater distances than RS-232 does. And the interface is compatible with V.35, RS-422/449, RS-530, and RS-485 equipment.
