In order to solve the above technical problems, the technical scheme is that：One kind is based on DMX512 control platform configuration fixtures
The method of RDM functions, increases two values section A and B, operation order is by A to B in the control passage of controlled plant：
The first step：Control passage stops n seconds for A sections first in numerical value, into controlled plant parameter setting mode, closing function
Output control, the DMX of current controlled plant is combined as according to the corresponding head passage numerical value C and second channel numerical value D in DMX addresses
Location simultaneously sets passage numerical value E, E=C*256+D；When only DMX addresses are more than 0 and are less than 513, E is just effective；Third channel
Numerical value F represents the channel pattern of controlled plant, is represented using sectional numerical value, and different numerical value segment tables shows different passage moulds
Formula；
Second step：Control passage stops m seconds for B sections in numerical value, and into controlled plant parameter affirmation mode, controlled plant preserves

Hardware realization
Relative to DMX512, RDM is realized in a device, and control device is mainly to increase the energy for receiving RDM feedback informations
Power.In traditional DMX512 systems, control device only needs unidirectionally to send control data, and therefore, communication port can be not required to
Possesses the ability of switching signal flow direction；And in standard RDM systems, control device is except needing the miscellaneous equipment into system
Send outside control data, it is also necessary to complete the remote management of equipment and miscellaneous equipment feedack in reception system, RDM rule
Surely the control data and feedack data sent are transmitted using same physical data, and therefore, control device is necessary
The signal of communication port can be flowed to and switched over.In RDM systems, the data flow of signal is substantially by control device
Definite.And common DMX controls platform does not have bi-directional signal flow handoff functionality, DMX controls platform configuration stage equipment proposed in this paper
RDM functions, which are realized, only needs control device to have the unidirectional function of sending control data can.It is actual in conventional control devices
