Avigilon Alta Control Center Administrator Guidefor more information on configuring Mobile Gateway settings.
Change I/O types
While I/Os on the 4-Port Board and 8-Port Board are labeled REX and CONTACT by default, you can use these
I/Os interchangeably or as generic inputs, by modifying their type in the Alta Control Center. You can also
change them to Wiegand inputs, which requires a few extra steps. For more information, see "Configuring Alta
Control Center with legacy systems" in the Avigilon Alta Control Center Administrator Guide.
