DMX512 electrical specifications are identical to those of the EIA-485-A standard, except where stated otherwise in E1.11 [example needed]. DMX512 is a bus network no more than 400 metres (1,300 ft) long, with not more than 32 unit loads (individual devices connected) on a single bus. If more than 32 unit loads need to communicate, the network ...
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.
Art-Net is a royalty-free communications protocol for transmitting the DMX512-A lighting control protocol and Remote Device management (RDM) protocol over the User Datagram Protocol (UDP) of the Internet protocol suite. [1]
XLR3 cable connectors female (left) and male. The XLR connector is a type of electrical connector primarily used in professional audio, video, and stage lighting equipment. XLR connectors are cylindrical, with three to seven connector pins, and are often employed for analog balanced audio interconnections, AES3 digital audio, portable intercom, DMX512 lighting control, and for low-voltage ...

DMX512 data are sent using EIA-485 voltage levels. However, quoting from E1.11,"The electrical specifications of this Standard are those of EIA-485-A, except where specifically stated in this document. Where a conflict between EIA-485-A and this document exists, this document is controlling as far as this Standard is concerned."
The Power Management Bus (PMBus) is a variant of the System Management Bus (SMBus) which is targeted at digital management of power supplies.Like SMBus, it is a relatively slow speed two wire communications protocol based on I²C.
A number of scroller manufacturers and third party vendors offer scrolls made with custom colours, assembled to a customer's specifications, though these are non-standard items and carry a premium. A custom adhesive, known as high-temperature scroll tape, is also available to allow technicians to repair sections of scrolls that have become damaged.
