The following ports are used by Fresco and the Fresco system.
The FCN ports can be customized to use a specific port number within Fresco Studio (Edit -> Preferences -> Advanced) or on the Fresco Touchscreen (Menu -> Setup -> Controller). Note that the FCN port numbers of all PC software and devices which need to communicate over Ethernet must be the same. Also, port numbers other than the default 61680 may prevent some diagnostic tools from working.
The BACnet port number is a station property which can be customized to use a specific port number within Fresco Studio (Hardware -> Select master station in tree -> Ethernet/BACnet tab) or on the Fresco Touchscreen (Menu -> BACnet). Note that the BACnet port numbers of all devices which need to communicate via BACnet must be the same or a router must be used to bridge the different ports.
