RDM---Remote Device Management
RDM is a wild version of the DMX512-A protocol, allowing dimming stations and other
control devices to be discovered through a DMX512 network, and then configuring,
status monitoring, and managing intermediate and line end devices.
It allows two-way communication between the lighting device or system controller and
the connected RDM compatible device through the standard DMX. 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 RDM, such as computer
lights or dimming cabinets, and remotely manage them through this connection
intelligence. Including the ability to remotely set the initial address of the DMX512, 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 DMX512 product on the same data link without any performance impact.
Since RDM runs on the first team DMX512 link, the only infrastructure upgrade required
by RDM is to upgrade the existing data distributor to implement a two-way mode to
support RDM.
The RDM information is transmitted through the first pair of DMX512 data channels.
RDM uses packets that include non-zero initial codes to start and control
communications. This alternating(rotating) session and waiting for indicative responses
is performed in a semi-duplex format. The second data pair is not used for any RDM
function.
Two-way data transmission-each vendor's equipment can exchange data, Art-net can
only transmit data, can not exchange with each other.
Its functions are as followed:
Enable & Run Factory Tests
Fault Finding
RDM
Change DMX Address
Rig Check
Change Mode
Invert Pan & Tilt
