VEmesh D2D – Wireless Extension to DALI Products
Designed and capable to replace any part of a DALI system wiring by wireless, VEmesh D2D – Wireless Extension to DALI is simple and offers high flexibility. D2D connects to all standard DALI-2 and DALI-1 devices and controllers, and supports all IEC62386 parts, such as DT1 (emergency), DT6, DT6, as well as the newer DT51 and DT52.
A D2D wireless network is formed by one VEmesh D2D Gateway and a number of Bridges. The Gateway connects anywhere on the DALI bus, usually next to the DALI Master. The VEmesh Bridge connects to the various DALI devices, with each VEmesh Bridge capable to support up to 8 DALI addresses. The Gateway supports up to 64 Bridges, and up to 64 DALI devices. The Gateway and the Bridge Nodes do not require a DALI address of their own.
In large deployments, up to 250 VEmesh D2D networks can operate in the same area; in large areas more networks can be deployed by frequency re-use. A VEmesh Toolkit is available to facilitate and to speed up the deployment and the maintenance.
The elements of a D2D network are: 1 Gateway, 1 to 64 Bridges and the optional VEtoolkit.
VEmesh E2D – IoT Extension to DALI Products
VEmesh E2D is a Smart Lighting control system, which is simple to deploy and to use, and it’s either stand alone or part of a Smart City system.
An E2D system is formed by one VEhub and a number of E2D wireless networks. In turn, each E2D wireless network is formed by one VEmesh Gateway and a number of Bridges. The Gateway connects to a standard Internet router for cloud control (such as via GPRS) or to a local server. The VEmesh Bridge, in various form factors, such as internal, or Zhaga, connects to standard DALI LED or other types of luminaires, or to sensors or actuators as required in a modern Smart City lighting system.
The Gateway can form networks of up to 16,000 luminaires, as opposed to DALI limitation of 64 devices per loop. For the system hub, the choice is between using VEhub or a customer’s CMS (Central Management System). A VEmesh Toolkit is available to speed up the deployment and the maintenance.
An E2D system comprises one VEhub (or customer’s CMS), up to 250 VEmesh E2D wireless networks, and one optional Toolkit. Each network requires one Gateway, and can support any number of Bridges for up to 16,000 devices, such as luminaires or sensors. In addition to standard DALI Bridges, E2D supports a variety of specialized ones, such as Input Bridges for sensors’ connection, with the latest addition being of Modbus Bridges, for connecting to energy consumption meters and other Modbus devices.
With high robustness and resiliency, low and deterministic latency, high range, practically unlimited number of Nodes and Hops per network, VEmesh is the optimal technology for wireless lighting control of streetlight and professional lighting, as well as for similar applications that require high performance wireless networks.
A VEmesh wireless network is formed by one VEmesh Gateway and an unlimited number of Node modules. The Gateway connects to the user’s remote or local management hub, with a choice between TCP/IP and USB types of connectivity. In deployments with a large number of networks, VEmesh Toolkit can be used to speed up the deployment and maintenance.
The elements of a VEmesh network are: one Gateway, any number of Nodes, and one optional Toolkit.
Virtual Extension offers Starter Kits for all its families of products, for the users to evaluate VEmesh suitability to their particular applications. Each Starter Kit usually includes one Gateway, a number of Nodes (or Bridges) and a Toolkit of the respective family of products.
VEmesh products’ certification
Virtual Extension is certified to act according to ISO 9001:2015 Quality Management System, for the development, manufacturing and marketing of its VEmesh wireless networks. The last ratification by the Standards Institution of Israel, an IQnet partner (International Certification Network), has been recently extended until 31 October 2021.
