"Disable filter" options which allow you
to disable the individual section filters.
Valid range: "none" = 0 ... 7
- Transport mode = unicast If you want to use the non-standard
multicast RTP-over-TCP transport mode, set this option
rtp-o-tcp accordingly. Otherwise, the transport
mode will be RTP-over-UDP via unicast or
multicast.
- [Red:Scan] Forces network scanning of SAT>IP hardware.
- [Yellow:Devices] Opens SAT>IP device status menu.
