Network Settings

Configure all network communication in Config → Network.

Ports

Service	Protocol	Default Port	Notes
Web UI / Remote control	HTTP	8123	Built-in Exaplay web service
Project updates	WS	8123	Live project events
Performance updates	WS	8123	Live diagnostics data
Effects service	HTTP/WS	3001	Live effects communication
Instance Discovery	UDP broadcast	45454	Auto-discovery of other Exaplay instances
TCP Command Server	TCP	8100	Configurable; see TCP Listen
UDP Command Server	UDP	8200	Configurable; see UDP Listen
OSC Receive	UDP	8000	Configurable
OSC Send	UDP	—	Destination configured per use
ArtNet	UDP	6454	Standard ArtNet port
NDI Discovery	mDNS	5353	Requires multicast

OSC Settings

Receive

Enable Receive OSC and set the Listen Port (default 8000). Exaplay 3 responds to the following OSC messages:

Address	Arguments	Action
/play	—	Start playback
/stop	—	Stop playback
/pause	—	Pause playback
/goto	f timecode	Jump to timecode (seconds)
/cue	s name	Fire cue by name
/cue	i number	Fire cue by number
/volume	f level	Set master volume (0.0–1.0)

Send

Enable Send OSC and enter the Destination IP and Port. Exaplay 3 sends:

Address	When
/timecode	Every frame during playback
/cue/active	When a cue becomes active
/status	On play, stop, pause events

TCP Settings

The TCP Command Server accepts plain-text comma-delimited commands over a persistent TCP connection. It is designed for show control systems, touch panels, and other devices that cannot easily send HTTP or OSC.

Setting	Description
TCP Listen	Address and port to listen on, one entry per line (e.g. *:8100 to listen on all interfaces on port 8100)

Leave the field empty to disable TCP control.

Use this for external show-control systems that send plain-text commands over a persistent connection.

UDP Settings

The UDP Command Server accepts the same comma-delimited commands as the TCP server, but over UDP datagrams. Each command arrives as a single datagram; the engine sends the complete response back to the sender as a single reply datagram.

Setting	Description
UDP Listen	Address and port to listen on, one entry per line (e.g. *:8200 to listen on all interfaces on port 8200)

Leave the field empty to disable UDP control.

Use this for simple one-shot commands sent as individual UDP packets.

ArtNet Settings

Not available in this build. ArtNet timecode receive is not yet wired up — there is no ArtNet settings panel and no Receive ArtNet TC control. Use OSC, LTC, or MTC for external timecode sync (see Timecode & ArtNet Sync). When implemented, the planned Receive ArtNet TC toggle will listen for ArtNet timecode (OpTimeCode) on the network. Note that ArtNet timecode packets carry no universe, and the receiver listens on all network interfaces — so there is no universe or network-adapter setting to configure.

Remote Access

The web UI is served from the engine's HTTP server and accessible from any browser on the local network at http://<engine-ip>:8123/.

Security note: There is no built-in authentication. Restrict access using your network firewall or a VPN. Do not expose port 8123 or 3001 to the public internet.

Firewall Configuration

Open the following inbound rules on the Exaplay machine's Windows Firewall:

TCP  8123     Exaplay Web UI & API
TCP  3001     Effects Server
UDP  45454    Instance Discovery (auto-discovery of other Exaplay instances)
TCP  8100     TCP Command Server
UDP  8200     UDP Command Server
UDP  8000     OSC Receive
UDP  6454     ArtNet
UDP  5353     NDI Discovery (mDNS)
TCP  5960+    NDI Data
