CASCADE Ports

The CASCADE ports allow UDM-0808-SIG Hubs to be chained together to increase the number of outputs
which can be delivered to the end points. The CASCADE IN and OUT connectors on the UDM Hubs require a
UDM-EXP-02 Cascade Cable (FG-1402-71 - not included).
CASCADE 5-8 IN
CASCADE 5-8 OUT
CASCADE 1-4 IN
CASCADE 1-4 OUT
FIG. 10 Cascade 5-8, 1-4 Ports
The CASCADE (Out) ports can also be used to send audio to the UDM-ABB-8-SIG Signature Series Audio
Breakout Box (FG1402-60). Refer to the UDM-ABB-8-SIG Audio Breakout Box section on page 71 for
details.
