The Pharos EDN 20 (Ethernet Data Node) is a convenient and scalable solution, providing cost-effective Ethernet-distributed DMX ports for large control projects. The EDN 20 is an easily configurable networking node that is specifically designed to add physical DMX ports to Pharos controllers and integrates natively with the full Pharos range.
Extremely compact, it packs 20 DMX512 output ports in just a 1U 19” form factor. For higher port count installations, nodes can be daisy-chained to provide as many physical DMX ports as you need as you need.
EDNs are discoverable through Pharos Designer software and associated to a Controller to be seamlessly configured as part of your patch. Ports can be flexibly assigned to any controller in your project providing an elegant distribution solution over an Ethernet network with minimal setup required.
The EDN 20 offers 20 DMX512 output ports to control your fixtures. Each port is independently galvanically isolated up to 2KV, ensuring the control circuitry and each port of the EDN 20 is protected against a multitude of electrical line faults, including earth potential rise and ground loops.
The EDN 20 is equipped with 20 “self-healing” DMX ports, giving your equipment added protection from incorrect setup and energy surges, such as short circuits, power induction and AC power faults. Should an energy surge occur, it will be contained by the EDN 20, preventing it from flowing into other components; once the external fault is cleared, the ports “self-heal”, restoring DMX output automatically.
Built from the ground up on Pharos technology, the EDN 20 natively interfaces with the rest of the Pharos product range including Pharos Designer software. Connecting it to your Designer lighting project is as simple as ensuring the EDN 20 is on the same network as the Controllers. From there, Designer will detect it, giving you full control of your Ethernet network lighting solution with minimal effort.
Up to 200 EDN 20 units and other Remote Devices can be combined with one or more Pharos Controllers on the same network to build the ideal system for your installation. Each Remote Device is easily addressed using a convenient thumb wheel. Whether one Controller or many, it’s all easily programmed using the Designer software.
RDM Capable (from v2.8)
Supports the Remote Device Management protocol (ANSI E1.20), allowing fixtures connected to any of the 20 DMX512 outputs to communicate back to their respectively assigned Controllers over an Ethernet network.
Works with any Controller in the Pharos range over an Ethernet network. A second network port is provided for daisy-chaining EDN 20s together. Our recommended limit of 8 daisy-chained EDNs is to ensure high performance; if that number is exceeded, some latency may become apparent.

SDI (Serial Data Interface)
The SDI is an accessory to the EDN 20. This enables any controller in the Pharos Designer range to output via the EDN + SDI a variety of serial protocols for controlling products such as addressable LED tape.
Both synchronous (SPI) and asynchronous serial lighting data are supported and these protocols allow for 1536 channels per port with supported cable lengths of up to 200m for asynchronous data and 40m for synchronous data.
