Designed and capable to replace any part of a DALI system wiring by wireless, VEmesh Wireless Extension to DALI (or D2D, for DALI to DALI) is deceptively simple and offers ultimate flexibility.
A D2D wireless network is formed by one VEmesh Gateway and a number of Bridges. The Gateway connects to the standard DALI Master (sometimes called DALI Router), while the VEmesh Bridge connects to standard DALI devices or sensors, with each VEmesh Bridge capable to support up to 64 such standard devices.
The Gateway supports up to 64 Bridges, and the total number of DALI devices of up to 64, which is DALI limitation, has to be observed. In large deployments, up to 250 VEmesh D2D networks can operate in the same area; then frequency re-use can be employed. In systems with multiple VEmesh networks, a dedicated VEmesh Toolkit is used for configuration.
The elements of a D2D network are: 1 Gateway, 1 to 64 Bridges and 1 VEtoolkit (optional; more than one can be used).
VEmesh IoT Extension to DALI (or E2D, for Ethernet to DALI) is a complete smart lighting control system, simple to deploy and to use.
An E2D system is formed by one VEhub and a number of E2D wireless networks. In turn, an E2D wireless network is formed by one VEmesh Gateway and a number of Bridges. The Gateway connects to a standard Internet router, which in a typical lighting system design may be a cellular type (such as GPRS). The VEmesh Bridge connects to standard DALI devices, such as one to four LED drivers in a luminaire pole, possibly including sensors.
The Gateway can form networks of up to 16,000 luminaires, as opposed to DALI limitation of 64 devices per loop. For the form factor of the Gateway, you have a choice between compact and DIN-rail, while for the system hub (sometimes called command and control center) you have a choice between using VEhub or a management of your choice, such as your existing one or of a third party. In deployments with a large number of VEmesh networks dedicated VEtoolkit can be used to speed up the deployment and maintenance.
The elements of an E2D system are: 1 VEhub (optional) Gateway, any number of Gateways (with one Gateway per each E2D wireless network), any number of Bridges and any number of VEtoolkits (optional).
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 UART, USB and TCP/IP types of connectivity. To low and medium volume Nodes’ customers we offer VEmesh modules, while to the high volume customers we also offer the VE209 IC controllers, thus enabling you to design your own devices. In deployments with a large number of VEmesh networks dedicated VEtoolkit can be used to speed up the deployment and maintenance.
The elements of a VEmesh network are: 1 Gateway, any number of Nodes – modules or controllers, and 1 VEtoolkit (optional; more than one can be used).
Virtual Extension offers Starter Kits of its various families of products, for the users to be able to check VEmesh suitability to their very applications. Each Starter Kit is usually comprised of on Gateway and several Nodes (or Bridges) of the respective family of products.
