Cascading Hubs
Overview
The UDM-0808-SIG features Cascade In/Out connectors which allow one UDM-0808-SIG to pass its inputs
to another UDM-0808-SIG. This cascade port can also be used to connect the UDM-0808-SIG to the
UDM-ABB-8-SIG Audio Breakout Box.
The UDM-0808-SIG supports up to eight inputs (A-H), and up to eight outputs (UDM Ports 1-8). Adding up
to three more UDM-0808-SIG Hubs is possible via the two sets of CASCADE ports (In/Out 1-4, In/Out 5-8),
and optional UDM Cascade Cables (FG-1402-71).
As indicated in FIG. 10 on page 10, the top set allows you to cascade Inputs E-H, while the bottom set is used
for cascading Inputs A-D.
Cascading UDM-0808-SIG Hubs requires physically connecting the Hubs via the CASCADE IN and
CASCADE OUT ports, as well as configuring the Source Hub and each Target Hub.

Up to four UDM-0808-SIG Hubs (one Source Hub and up to three Target Hubs) can be cascaded
together.

Using these connectors does not reduce the number of available user ports.

Cascading can increase the overall size of the matrix from 8x8 to 8x32.

Inputs are only cascaded down the chain (not bi-directional).

Each Hub can be assigned as either the Source Hub or as a Target Hub via NetLinx Send
Commands ("MMON" and "MMOFF" - see page 83 for details).
Cascade In/Out Connectors
The CASCADE IN and OUT connectors on the UDM-0808-SIG require a UDM Cascade Cable
(FG-1402-71 - not included).
FIG. 66 Cascade 5-8, 1-4 Ports
CASCADE IN ports 5-8: from Source Hub’s CASCADE OUT 5-8 port
CASCADE OUT ports 5-8: to Target Hub’s CASCADE IN 5-8 port
CASCADE IN ports 1-4: from Source Hub’s CASCADE OUT 1-4 port
CASCADE OUT ports 1-4: to Target Hub’s CASCADE IN 1-4 port
Cascaded Hubs must be stacked on top of each other, to ensure that the 6"
(15.24cm) UDM Cascade Cable is able to reach from Hub to Hub without strain.
