system was based on frequency-hopping spread spectrum (FHSS) technology using commercial wireless modems. Other later-generation systems still used frequency-hopping spread spectrum (FHSS) technology, but at higher bandwidth. FHSS systems tend to disturb other types of wireless communication systems such as WiFi/WLAN. This has been solved in newer wireless DMX systems by using adaptive frequency hopping, a technique to detect and avoid surrounding wireless systems, to avoid transmitting on occupied frequencies.

The E1.11 (2004) standard relaxed the transmitter and receiver timing specifications. This relaxed the timing requirements for systems using controllers built to DMX512-A (E1.11); however, a significant number of legacy devices still employ transmit timing near the minimum end of the range.

A DMX512 network is called a "DMX universe". 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

In the 1986 and 1990 standards the use of the second data pair is not defined other than as an ‘optional second data link’. Both unidirectional and bidirectional use were envisioned.

The E1.11 (DMX512 2004) electrical specification addresses the connection of DMX512 signal common to earth ground.

Each slave device has a DMX512 "IN" connector and usually an "OUT" (or "THRU") connector as well.

A second cable then links the OUT or THRU connector of the first slave to

Many alternatives to DMX512 have been proposed to address limitations such as the maximum slot count of 512 per universe, the unidirectional signal, and the lack of inherent error detection. The 2004 DMX512-A revision added a System

Cabling for DMX512 was removed from the ANSI E1.11 standard and a separate cabling standards project was started in 2003. Two cabling standards have been developed, one for portable DMX512 cables (ANSI E1.27-1 – 2006) and one for permanent installations (draft standard BSR E1.27-2). This resolved

Additionally, terminating the DMX line often exposes physical cable faults - for example, if the "Data −" wire is broken, an unterminated DMX run may partially work, while fitting the terminator immediately exposes the problem.
