An E2D system comprises one VEhub (or customer’s CMS), up to 250 VEmesh E2D wireless networks. Each network requires one Gateway, and can support any number of Bridges for up to 16,000 devices, such as luminaires or sensors.

On the RF side, a VEmesh network comprises of one VEmesh E2D Gateway and a number of Nodes. The VEmesh Bridges are the Nodes of an E2D Network.

On the DALI side, each VEmesh Bridge connects to one or more standard DALI devices or sensors, with a VEmesh Bridge capable to support up to 4 such devices – either on a pole for streetlighting or in a building. The Bridge actually forms a DALI loop, with the connection following DALI standard IEC 62386.

Through this connection, the Bridge receives all DALI signals from the DALI devices that it is connected (such as LED drivers replies and input devices’ events), and forwards them to the VEmesh wireless network. In the opposite direction, the VEmesh Bridge receives the DALI Master commands and forwards them on its DALI loop to the devices that it is connected.

One E2D Bridge supports 1 to 4 devices and it does not require a DALI address of its own.

The Bridge has a plastic case and its dimensions are 149.5mm x 40mm x 28.1mm (5.89” x 1.57” x 1.1”).

The VEmesh Gateway comes in three variations: E2D, Modbus, and D2D, each designed to facilitate specific wireless network architectures.

VEmesh Gateways  primary use is to enable wireless communication between DALI luminaires and other devices, such as controllers, sensors, or management systems, using various wireless technologies: E2D, D2D, or Modbus. They ensure seamless integration and interoperability between these devices and networks, allowing for efficient control and management of lighting systems.

E2D (Ethernet to DALI): Facilitates integration with DALI luminaires through Ethernet connectivity, enabling seamless communication between the luminaires and a network hub.

D2D (DALI to DALI): Enables direct communication between DALI devices within a network, streamlining device-to-device interactions without the need for an intermediary hub.

Modbus: Forms a vital part of lighting control systems, comprising a Modbus-based management hub and Modbus E2D networks connected to DALI luminaires, allowing for comprehensive management and control of lighting systems via Modbus protocols.

VEmesh D2D (DALI to DALI) Bridge Node is a family of VEmesh network devices that are part of Wireless Extension to DALI (D2D) solution. These networks add wireless capability to regular DALI (wired), thus increasing your productivity of lighting control deployment, lowering the maintenance costs and enabling you to operate in places that otherwise would be difficult to access. You can keep using all you existing DALI luminaires, drivers, controllers, sensors, and other DALI devices as is, eliminating your need to invest in dedicated wireless DALI products. As such, D2D is a simple and intuitive solution for replacing wires by wireless, where needed or in all DALI network.
In a VEmesh D2D Network, the connection of the DALI devices is through VEmesh D2D Bridge Nodes. Up to 64 x D2D Bridge Nodes and 1 x D2D Gateway form together a VEmesh D2D network for high performance and cost-effective wireless DALI connectivity. Each VEmesh Bridge Node can support up to 64 DALI short addresses of control gear, such as LED Drivers. In addition, you can use D2D Nodes to connect to switches, presence detectors and sensors with application controllers for DALI and various extensions to the leading suppliers of standard DALI products on the market.
VEmesh D2D supports simultaneous operation of up to 250 D2D Networks in the same or adjacent location, for large lighting systems. The configuration for multi-network systems uses the D2D Toolkit.

VEmesh D2D Bridge Node is designed to operate with devices complying with DALI1 and DALI2 (IEC 62386 relevant parts).
All VEmesh products use synchronized-flooding technology for utmost wireless performance, including space diversity and time diversity for highest propagation robustness. They also use Frequency Hopping, which in Europe employs LBT and AFA for maximum transmission power and range. The supported RF wireless regulations are of Europe, North America, South America and Israel, depending on the model.
VEmesh D2D Bridge Node has an Internal Antenna for improved cost-effectiveness; external antenna is an option.

VEmesh E2D Zhaga Bridge’s functionality is basically similar to VEmesh E2D Bridge Node. Its form factor has been designed according to Zhaga book 18 standard, for fast installation and additional interchangeability in street lighting with DALI luminaires and sensors.
