which must be URL encoded. If the percent symbol is not encoded, it is
treated as the start of a hexadecimal command. For example, the
command “POWER%ON” must be entered as “POWER%25ON”, where
% indicates that a hex character follows, and 25 is the hexadecimal
equivalent of the ASCII percent symbol.
12. Select whether the command should be sent when the button is pressed or
when it is released.
13. Click OK.
14. Repeat steps 6 through 13 as needed.

Volume Controller

installations that include wireless microphones, wired microphones, other audio

volume controller (such as the Extron MVC 121) can be useful integration
accessories. The following diagram shows a sample of this type of system.
