Send & Receive DMX512 with sACN packet

ANSI E1.31 - 2018 Entertainment Technology - Lightweight streaming protocol for transport of DMX512 using ACN https://tsp.esta.org/tsp/documents/published_docs.php

Read/Write sACN packet using mapping memory with Swift struct memory layout.

Packets

• Data Packet
  • Root Layer
  • Framing Layer
  • DMP Layer
• Universe Discovery Packet
  • Root Layer
  • Framing Layer
  • Universe Discovery Layer

Source: send sACN packets, via standard multicast, and non-standard unicast and directed broadcast

Source Scheduler: manage its emission interval dynamically within 25ms (frequent) - 800ms (idle)

Sink: receive sACN packets, ignore local endpoints (sent by the directed broadcast)

Sink Scheduler: receiver with configurable interval for downstream, in case an upstream is too fast

Transports

• sACN multicast (239.255.UniverseHi.UniverseLo)
• directed broadcast
• unicast
• Multipeer Connectivity

Conflict Resolver (Universe Merge)

• Newset
• Higher Takes Precedence (HTP)

2. DMXRelay: specific app utilizing "relay" for different transports, for example configuration:

// Device U1 <--Multipeer Connectivity-- Relay <--localhost:5569-- U3 TouchDesigner
// Device U2 --Multipeer Connectivity--> Relay --localhost:5568--> U4 TouchDesigner
