Configuring the daisy chain
Figure 2-8 is an example of daisy chaining ten VSW 2VGA A
switchers. In the example, the output of the first switcher in
the chain (

Additional switchers in the chain output to Input 2 of the
previous switcher.
Daisy chaining requires the setting of jumpers. (See the next
section, "Setting VSW 2VGA A Jumpers".) The three jumper
tables in figure 2-8 indicate how the jumpers must be set. Note
that Table 1 is assigned to switchers

Up to ten switchers can be daisy chained without any
degradation in picure quality. One 12 VDC power
supply is required for every group of five daisy chained
switchers. The power supply must be connected to the
middle switcher. In the example, the power supplies are
connected to switchers
The installer should label each switcher in numerical
order so that its position in a daisy chain can be readily
identified at a future date.
In the example, the VSW I AAP interfaces output to
Input 1 of its attached switcher. Press the
VSW I AAP's Input select (Show Me) button to route
the interface's input to the projector.
Daisy chaining audio signals is similar to daisy chaining
video signals. In figure 2-8, audio is output from the
VSW I AAP to the switcher's Input 1 audio input. The
switcher's audio output is then input to the Input 2
audio input of the next switcher in the daisy chain.
