A DMX512 network is called a "DMX universe". [4] Each OUT connector on a DMX512 controller can control a single universe. A DMX512 universe is made up of 512 channels, with each channel containing a value between 0 and 255. Each slave device in the chain can "look at" a different set of channels in order to be controlled by the master controller.
A slide-style DIP switch soldered into a printed circuit board (PCB) Schematic symbol for each individual switch. A DIP switch is a manual electric switch that is packaged with others in a group in a standard dual in-line package (DIP). The term may refer to each individual switch, or to the unit as a whole.
Addressing is typically fixed per node, often locked to the MAC Address and an "OEM" code allocated to the manufacturer, and jumper settings. Networks can use DHCP or statically configured IP addresses, and use unicast packets for greater network efficiency. The protocol can address 32768 DMX "universes", each of 512 channels, limited by bandwidth.
Remote Device Management (RDM) is an addition to the DMX512 control protocol for stage lighting equipment, introduced in 2006. DMX512 was developed in the late 1980s as a standard protocol for lighting consoles to communicate with dimmers, but has since been used for more complex applications, including the control of intelligent lighting fixtures.
These lighting console solutions use software with a feature set similar to that found in a hardware-based console. As dimmers, automated fixtures and other standard lighting devices do not generally have current standard computer interfaces, options such as DMX-512 ports and fader/submaster panels connected via USB are commonplace.
Digital Addressable Lighting Interface (DALI) is a trademark for network-based products that control lighting.The underlying technology was established by a consortium of lighting equipment manufacturers as a successor for 1-10 V/ 0–10 V lighting control systems, and as an open standard alternative to several proprietary protocols.
Five-pin male 180° DIN connector from a 1988 Schneider MF2 keyboard by Cherry. The DIN connector is an electrical signal connector that was standardized by the Deutsches Institut für Normung (DIN), the German Institute for Standards, in the mid 1950s, initially with 3 pins for mono, but when stereo connections and gear appeared in late 1950s (1959 or so), versions with 5 pins or more were ...
Earl Simmons was born on December 18, 1970, in Mount Vernon, New York. [11] He was the son of 19-year-old Arnett Simmons and 18-year-old Joe Barker. [12] Simmons was the middle child of the family; his mother had given birth to a daughter, Bonita, two years prior, and later gave birth to a second daughter, Shayla, and two stillborn sons. [1]
