SDIM Subnet

An SDIM subnet allows the Imagine 920 Router In the sense of a lighting system, a router is an intelligent device whose software and hardware perform the tasks of routing and forwarding messages (data) from control devices to the control gear. A router contains two or more subnets. to drive control gear For example, dimmers, relay units, ballasts etc. Control gear receives messages from control devices via the router, and performs the relevant action; for example, it sets the lighting (lamps) that it controls to the relevant level. Some control may be possible at the device itself. Also known as LIU or Load; see entries for both. such as the Imagine Helvar’s range of products based on Helvar’s SDIM protocol. range of dimmers, relay units and ballast controllers, or DIGIDIM Helvar’s range of products based on the DALI standard. The DIGIDIM range is composed of a series of controllers and lamp interface units that are designed to communicate using DALI commands. loads with SDIM capability. The router has one SDIM subnet that can support up to 128 SDIM devices, within the limits of 252 SDIM addresses. For more information about these limits and how they may affect your lighting system A network of client PCs, routers, control devices, control gear, and lamps, contact Helvar Customer Support.

SDIM Subnet Communication

SDIM is an internal Helvar protocol used to communicate between SDIM devices (control gear) on an SDIM subnet. Unlike DALI Stands for Digital Addressable Lighting Interface. Standardised digital protocol for lighting control, allowing communication between control devices and LIUs (control gear). devices, whose addresses are automatically set by the router system, SDIM addresses are set at the device A physical item with which you can interact, either directly or via Designer. by a DIL Stands for Dual Inline. A small two-state switch used on electronic devices, normally used to set device configuration settings. switch or menu selection. There can be one or more addresses, depending on how many channels the device has.
