Interoperability

Maximum flexibility for you

Seamless integration and sharing of information across a digital network deliver better, smarter lighting systems. eldoLED's globally compliant drivers collaborate and connect with whichever lighting systems components are right for your installation.

 

Interoperability creates a better lighting experience, adds value through extended functionality, and pushes dynamic, intelligent lighting into whole new application areas. The eldoLED driver is at the heart of an LED ecosystem, with its LEDcode bus offering digital control, and combining data and power over 2 wires.

 

Our LED drivers are intelligent, open platforms that support numerous control systems: DALI, 0-10V, DMX, BLE for wireless lighting control, nLight, LEDcode and 0-10V control with standby option.

 

 

DALI Leadership

DALI (Digital Addressable Lighting Interface) is a protocol for digital lighting control that enables robust, scalable and flexible lighting networks. With the introduction of DALI-2 in 2014, testing 

became much more comprehensive in order to ensure interoperability of compliant products and a certification program was established and is managed by the independent Digital Illumination Interface Alliance (DiiA). Today, there are more DALI-2 DiiA Certified drivers from eldoLED than any other provider. We are committed to developing driver solutions that are DALI-2 Certified and interoperable with the sensors, systems and solutions you use.

 

The first DALI-2 DT8 (Tc) Certified drivers


 

 

Drivers using the DT8 protocol, can use a single DALI short address to control two or more outputs and this is of great advantage in dynamic or tunable white applications. The DALI-2 DT8 (Tc) technology allows changes to the color temperature and intensity of fixtures within an LED lighting system. Introduced in early 2020, eldoLED DUALdrive LED drivers were the first to receive certification from the DiiA.

 

 

0-10V and 1-10V

0-10V and 1-10V are easy to understand systems and commissioning does not require specialized knowledge. However, to get different control groups each group needs separate wiring. 

0-10V and 1-10V do not support bidirectional communication –so if sensors are required, additional systems may be necessary. 0-10V and 1-10V systems are best suited for simple installations. In complex systems, installation can get complicated because each group need its own wiring. 0-10V is mostly used for entertainment lighting, 1-10V is more common for general lighting.

 

Wiring

The 0-10V signal is sensitive to external disturbances. The 0-10V wires should not run next to mains cables or be placed next to potential noise sources like big motors or fans.

 

Due to different lengths in signal wires, voltage drops can cause different light outputs. Larger diameter wiring causes less apparent differences in light outputs. Best would be to have equal length signal wiring if possible.

 

eldoLED drivers can change the dimming curves in a 0-10V system and adapt to different dimmers.

 

Dimming curves

Not all manufacturers publish their controller's dimming curve, so test upfront. eldoLED drivers can change the dimming curve via the FluxTool programming tool to adapt your driver to different dimmers.

 

Advantages of 0-10V dimming

  • Traditional way of dimming, known protocol.
  • No (software) commission needed.
  • Low cost dimming method.

 

Disadvantages of 0-10V dimming

  • No addressing is possible, all connected LED-drivers react identical on a command from their controller.
  • Groups options can only be created by adding extra 0-10V networks (i.e. extra controller and extra cabling).
  • Polarity sensitive wiring.
  • Dimming curve is not standardized on shape and tolerance (linear, logarithmic, square, soft-linear).
  • Long wire distance needs special attention because of voltage drop and potential noise from environment.

 

 

DMX

DMX was originally created for the theatre industry, but today DMX is also widely used for dynamic architectural lighting. One of

the benefits of DMX is that it is fast –changes in intensity and colour can be made virtually instantly. With DMX/RDM, bidirectional communication is possible. DMX/RMD can be used for automatic addressing during commissioning and for status reporting of connected devices.

 

The protocol

A DMX controller sends messages to each device in its network. The protocol sends a value between 0 and 255 to each of the 512 channels. For example, the value can be used to set a light level, but also to set the position of a moving head or to change gobos.

 

One connected device can/will use multiple channels. For example, a luminaire connected to a four channel LED driver assigned to channel 5 will also use channels 6, 7 and 8 – this means that only 128 devices could be connected within the 512 channels.

 

RDM - bi-directional flexibilty

RDM adds bidirectional communication to DMX. This is especially useful during commissioning. Without RDM, a channel must be assigned to each device. And if a channel must be changed of a device hanging high above the stage in a theatre, someone has to go to that device physically to change its channel. With RDM, channels can be assigned automatically by the controller, without the need to program each device separately.

 

Advantages of DMX/RDM

  • Standardized protocol (USITT DMX512-A) and based on RS-485.
  • Made for colour dynamics, but also for sound & moving heads.
  • Fast –suitable for highly dynamic light shows.
  • One DMX universe can handle 512 individual addresses.
  • Large distance possible between the controller and the last driver (up to 300 meters).
  • No need to program the driver individually – can be done via the RDM controller.
  • Status of connected devices can be reported.

 

Disadvantages of DMX/RDM

  • Complex –specialised knowledge is needed.
  • Special cables required for control signals (EIA-485 or CAT5E).
  • Individual programming of drivers is needed (not with RDM).

  

Controls Protocol Summary

 

 

 

DALI

A flexible system that can be used to create separate lighting groups with easy wiring. Special knowledge is required for software commissioning.

 

 

 

0-10V / 1-10V

Low cost system with easy commissioning, but not as flexible or powerful as DALI.

 

 

 

DMX / RDM

System suited for dynamic (colour) lighting and architectural illumination, particularly where dynamic fades and rapid lighting effects and changes are required.
