Maximizing Performance Of Cascaded UDM-0808-SIG Hubs

At cable runs longer than 100m, the RX unit should be powered using a local power supply.

When two VGA signals are placed on adjacent inputs (e.g. A and B, B and C, C and D), they should
be set to different resolutions and/or refresh rates.

Do not running audio on an input if it's not needed.

On installations with less than eight inputs, the inputs should be spaced as far apart as possible. For
example, on an installation with four inputs, inputs A, D, E, and H should be used.
Configuring a UDM-0808-SIG Hub For Cascading
The UDM-0808-SIG sends the inputs it is using to the Cascade output (no configuration required).
The exception to this is audio, which can be set to output either the audio inputs or outputs (see Using the
UDM-ABB-8-SIG Audio Breakout Box below).
On an UDM-0808-SIG that has signals cascaded into it, you can choose the cascade input using the SVI (see
page 21) and SAI (see page 20) SEND COMMANDs. If you append 'CASCADE' to the end of those
commands, the UDM-0808-SIG will use the cascaded input in place of the local input.
Refer to the Configuring the Source Hub section on page 82 and the Configuring the Hub as a Target
Hub section on page 83 for details.
Using the UDM-ABB-8-SIG Audio Breakout Box
The UDM-ABB-8-SIG Audio Breakout Box is used to convert the analog and digital audio inputs to analog
and digital outputs in a way that tracks the configuration of the UDM-0808-SIG. For example, consider the
following examples (FIG. 69 & FIG. 70):
In the example shown in FIG. 69:

Source 1 is routed to UDM-0808-SIG Outputs 1 and 2

Source 2 is routed to Output 3
