In most cases, the default settings of the SW5200 are sufficient for most applications. However,
there are times when changes are needed. In these situations, PS has created a Windows-based
application which helps users and integrators make these changes. This application is called
“PS Switcher Settings” and can be downloaded from the SW5200 webpage of the PS website.
Further explanation is provided later in this document for this application in the
Switcher
Settings
section.
Here are some settings that can be viewed or changed:
•
EDID table and resolutions
•
Ethernet setings
•
Volume adjustments
•
Auto-switching On/Off
•
Display inactivity shutdown timeout
•
Proximity sensor On/Off
