DMX512 and RDM node
MADRIX STELLA 8 is the flagship node that brings eight DMX512 ports together in a single DIN rail device: 1 Gbit/s network, PoE power, RDM, merging of up to eight sources and backup that kicks in when the connection is lost.
Authorized dealer and solution partner
STELLA 8 was designed for large DMX systems that must run without interruption. Each of the eight ports can be set as an output or input; incoming data is merged, duplicated or converted to another protocol. All of this is done from the device’s web interface, even from a phone.
Thanks to source priorities and backup strategies, if the main control source is lost, STELLA 8 switches to the next one; if no source remains, it plays patterns or single-frame snapshots stored on the device. The facade never goes dark. The power supply can be redundant too: the DC terminal, USB-C and PoE can be connected at the same time.
1 Gbit/s Ethernet eliminates bottlenecks in networks with many universes. RDM and Art-Net packets are sent simultaneously; luminaires can be configured and monitored while the show runs. With MADRIX RADAR, all RDM devices connected to STELLA 8 are unlocked free of charge.
Highlights
Each port is a DMX output or input; DMX input is sent back to the network as Art-Net or sACN.
HTP or LTP merging of up to eight sources, with no latency; 32 sources and 32 destinations in advanced mode.
If the connection is lost, it switches to the next source in the priority order or to the patterns and snapshots stored on the device.
5–24 V DC (with power bridge), two USB-C or PoE; more than one can be connected together as a backup.
Daisy chaining with two RJ45 ports; a network connection over USB provides setup and backup access.
In 13 languages including Turkish, mobile-friendly; password protection, channel offset, color order and brightness limits.
Data rates and channels are shown live in the port, DMX and device monitors; logging to a remote server via syslog.
Galvanic isolation and fast current limiters protect the ports against overvoltage.

Each of the eight ports carries one DMX universe (512 channels); that comes to 4,096 channels per device. Since ports can be set individually as inputs or outputs, the same device can work as both a splitter and a combiner.
Yes. STELLA 8 is powered from a single Ethernet cable via IEEE 802.3af PoE and draws at most 5 W. If you like, the DC terminal or USB-C can also be connected as a backup supply.
Source priorities and backup settings take over: STELLA 8 switches to the next source or plays a pattern or snapshot stored on the device. So the lighting does not go out unexpectedly.
Yes. STELLA 8 receives both protocols, converts between them and merges them. When two systems using different protocols need to drive the same luminaires, it acts as a bridge.
All settings are in the device's web interface; the interface is available in 13 languages including Turkish and is mobile-friendly. With ready-made setting templates, common setups are completed in a few clicks.
