PRELIMINARY
Labeling the PVT Decora face plates
To help identify the input number and type of signal that 
any PVT Decora transmitter sends to the PVS switcher 
when the transmitter is installed, a series of small labels 
are supplied. A label identifying the transmitted signal 
type should be affixed to each Decora faceplate (top or 
bottom) where it can easily be seen after installation. This aids the user to connect 
a device corresponding to the plate transmission signal type, allowing correct input 
switching at the PVS 204SA.
Final Setup
With an MLC 104 IP Plus as a standard MLC controller in the PoleVault system 
package, your nal PVS 204SA switcher setup should look similar to the gure 
below.
Ensure all connections are correctly made and secure.
