DMX-Net RDM* discourages excessive daisy-chaining, making fault isolation easier, and time to repair shorter. Instead of one DMX outlet in the FOH slot, put in four or five; a damaged cable will disable only a few color scrollers instead of every FOH unit. Install an input and then take your DMXter4 with you, for easier trouble shooting.
Unlike systems using passive wall plates, the DMX-Net RDM user doesn’t need to know the hidden wiring topology. Each output provides a galvanically isolated RDM controller port with a guaranteed full strength signal. There are no hidden stubs. No other outlets with unterminated or over terminated cables to cause reflections. Ground loops are controlled. Radio frequency grounding is stable, unlike with ad hoc portable splitters.
The system consists of two types of RDM port modules, one for input and one for output. They are fitted with Neutrik connectors and will fit in a single gang box. They are ideal for use in low voltage chambers of power battens and truss wire ways.
Each module has a bi-color tally LED. The LED indicates the status of each module - is it powered and available, is it inputting or outputtng data, or is there a fault condition.?
Each module is connected by a two piece screw terminal connector to a private RDM distribution bus. The bus provides a DMX/RDM pair, power, power common, and shield. All modules include a terminator for the private bus; the ones at the ends of the bus are enabled during installation. If required the private bus may have branches (star topology). This requires adding a branching module for each branch.
The low cost of the hardware and installation of DMX-Net RDM will allow more RDM ports, more flexibility, and greater fault isolation. Even in systems using DMX512 alone, DMX-Net RDM allows the creation of flexible networks that are impossible to achieve with any standard splitter topology.
