4.3 Data

DMX 512 data is transmitted at 250 kiloHertz (kHz), meaning that 250,000 1’s and 0’s (at a maximum) can be sent each second. Each bit is measured in 4 microsecond (µs) intervals. In order for the receiving device to correctly interpret the data, it must be sent in a particular sequence. A single transmission (DMX Packet) includes synchronizing elements and channel data for up to 512 channels (Figure 8).

NOTE: At a minimum, a fully loaded DMX Packet (data for all 512 channels) will be around 5700 bits in size. This means about 44 DMX Packets can be sent each second.

WARNING: DMX 512 has no error prevention, and is prohibited from use in life-safety applications such as pyrotechnics or set/rigging motion control.
