T/CALI 0602-2019 Remote Device Management (RDM) protocol for LED lighting based on DMX512 network
Basic Information
Scope
Main technical content: The Remote Device Management (RDM) protocol allows intelligent two-way communication between devices from multiple manufacturers using a modified DMX512 data link. RDM is defined in the WH/T 32 standard (DMX512-A) to implement enhanced topology functions EF 1.0 in DMX512 networks. In this standard, RDM allows consoles or other control devices to locate devices through the DMX512 network, and then configure, monitor, and manage these intermediate and terminal devices. RDM provides intelligent control of DMX512 network devices, a function that was previously unavailable except on dedicated networks. This standard specifies the following: physical layer and timing, device search process and algorithms, message structure, and communication.
