Technical introduction of DMX512/RDM
RDM is an extended version of the DMX512-A protocol that allows dimming stations and other control devices to be discovered through a DMX512 network, and then configure, condition monitor, and manage intermediate and line end devices.
It allows two-way communication between lighting devices or system controllers and connected RDM compatible devices through standard DMX lines. This protocol will allow these devices to be configured, monitored, and managed in a manner that does not interfere with the normal operation of standard DMX512 devices that do not recognize the RDM protocol.
Allow a controller or test device to find other devices that can be managed by RDM(remote device management) through this connection intelligence, such as computer lights or dimming cabinets, and remotely manage them. Including the ability to set up the DMX512 initial address remotely, query the device's errors or statistics, and achieve most of the configuration settings that are usually done on the front panel of the device. RDM can run with the new RDM device or any original DMX 512 product on the same data link without any performance impact. Since RDM runs on the first pair of DMX512 links, the only infrastructure upgrade required by RDM is to upgrade the existing data distributor to implement a two-way mode to support RDM
