Qt X Network ports and protocols
This article details all of the ports and protocols used by Qt X devices, as well as the ports and protocols used by PCs running Qt X software or discovering controllers via the web UI.
The Qt X system can be configured for single cable or dual cable modes which will determine what protocols are seen on each corresponding LAN port respective to the running mode. The web UI is reachable via both the Control or Media IP address in both modes.
Control
| Port | TCP / UDP | Protocol | Notes |
|---|---|---|---|
| 5353 | UDP | mDNS | Device discovery
mDNS port is enabled and not configurable. |
| 443 | TCP | HTTPS | Web management interface. |
Note: SSH and Telnet ports are not used in any of the Qt X controllers and are not open.
AVB
Gigabit Ethernet (1000Mbps)
Depending on network configurations in Qt X setup, the AVB/Dante ports may also utilize the Control NIC protocols
| Port | TCP / UDP | Protocol | Notes |
|---|---|---|---|
| 17720 | UDP | IEEE1722 | AVB Transportation Protocol (AVB Streams) |
| 17721 | UDP | IEEE1722-1 | AVDECC Discovery Protocol / Enumeration and Control Protocol |
Dante
Gigabit Ethernet (1000Mbps)
Depending on network configurations in Qt X setup, the AVB/Dante ports may also utilize the Control NIC protocols
| Port | TCP / UDP | Type | Notes |
|---|---|---|---|
| 8850 | UDP | Unicast | Via control & monitoring (Internal) |
| 38900 | UDP | Unicast | DVS control & monitoring (Internal) |
| 8899 | UDP | Unicast | DVS control & monitoring (Internal) |
| 8000 | UDP | Unicast | Dante Domain Manager Device Port |
| 8001 | UDP | Unicast | Dante Millau Device Proxy (Internal) |
| 8002 | UDP | Unicast | Dante Lock Server |
