The Pharos EDN 20 (Ethernet Data Node) is a convenient and scalable DMX512 solution, providing cost-effective Ethernet-distributed DMX ports for large lighting control projects. The EDN 20 is an easily configurable networking node that is specifically designed to add physical DMX ports to Pharos lighting controllers and integrates natively with the full Pharos architectural lighting control range.
Extremely compact, it packs 20 DMX512 output ports in just a 1U 19” form factor. For very high-channel count lighting installations, nodes can be daisy-chained to provide as many physical DMX universe outputs 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 lighting 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 lighting 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 lighting installation. Each Remote Device is easily addressed using a convenient thumb wheel. Whether one Controller or many, it’s all easily programmed using our Designer software.
RDM Capable (from v2.8)
Supports the Remote Device Management protocol (ANSI E1.20), allowing discovery and addressing of fixtures connected to any of the 20 DMX512 outputs.
Works with any Lighting Controller in the Pharos range over an Ethernet network. A second network port is provided for daisy-chaining EDN 20s together. We recommend a limit of 8 daisy-chained EDNs to ensure high performance.

Ethernet Data Node 20 (1 + 1 Ethernet, 20 DMX/RDM)
SDI (Serial Data Interface)
The Pharos SDI (Serial Data Interface) is an accessory to the Pharos EDN 20 (Ethernet Data Node). Together they enable any controller in the Pharos Designer range to output a variety of serial protocols for controlling products such as addressable LED tape.
The EDN 20 is configured as a whole either to output DMX directly to fixtures or to output one of a range of serial protocols with an SDI required for each active port. Both synchronous (SPI) and asynchronous serial lighting data are supported and these protocols allow for 1536 channels per port.
Each SDI should be placed close to the fixtures it is controlling, with its DC input range of 5-28V giving the flexibility to use the same power supply as the fixtures. Supported cable lengths from the EDN 20 are up to 200m for asynchronous data and 40m for synchronous data.
Compatible with with all controllers in the Pharos Designer range, the combination of EDN 20 with SDI is particularly appropriate for very high capacity installations using the VLC family, flexibly mapping video to LED tape or custom lighting fixtures. The Pharos VLC with Pharos EDN + SDI combination will provide a cost-effective single-manufacturer control solution, all the way way to the fixture.
