From the File menu, select Save As, make a duplicate copy of the modified file with a new name,
and save it to the PC. (We strongly recommend making a duplicate copy every time the file is
modified.)
Caution:
The system must not be actively switching when loading this information onto the system.
You may want to disconnect any external controllers to ensure that no switches are executed during
the loading of the file.
Spanning Grouping Pattern
For switching purposes, Precis HT connectors can be only be grouped into a spanning pattern, as these
systems do not support sequential grouping. When a Precis HT system is configured in a spanning
grouping pattern, each of the component (standard) signals in an aggregate signal is assigned to
vertically adjacent connectors. The same pattern is then repeated for the outputs.
Example
In the 12x8 RGsB + Stereo system in FIG. 28, the “R” component is assigned to the first (farthest left)
input connector on the first row of connectors, the “Gs” component to the first input connector on the
second row, and the “B” component to the first input connector on the third row. This pattern is repeated
for the output connectors. The stereo audio signals are assigned to the applicable input and output
connectors.
Note:
The typical system setup will use one set of audio connectors. The Precis HT system
can include both analog and digital audio signals when switching on VM 0 (see page 56).
The first input channel of VM 0 (All VMs) includes all three components of the RGsB signal (the first
input connectors on each row of connectors), plus the audio signal (the first stereo audio connector).
When you switch Input 1 on VM 0, the RGsB and the stereo audio signals are routed simultaneously on
VM 0. Each of the twelve grouped RGsB input channels and their corresponding stereo audio input
channels can be routed to any or all of the eight available corresponding output channels.
Video and audio breakaway signals can also be routed by using the pre-configured virtual matrices. In
the example in FIG. 28, when you switch Input 1 on VM 1, the RGsB signal is routed. When you switch
Input 1 on VM 3, the stereo audio signal is routed.

Grouping connectors in a spanning pattern
VM 0 = RGsB + Stereo Audio + Digital Audio (not connected in this example)
VM 1 = RGsB
VM 2 = Digital Audio (not connected in this example)
VM 3 = Stereo Audio
Virtual Inputs: RGsB + Stereo Audio = 1st input channel of VM 0
