BEST BOY 4000 ® SPOT LUMINAIRE USER MANUAL 91
8-Bit DMX
The universally accepted lighting control protocol in the entertainment industry. A console uses this protocol to
control specific devices in a lighting system. A DMX512 channel packet is eight bits of absolute parameter data. 8-bit
refers to the resolution of the signal: 256 step resolution, providing channel values from 0 through 255. A DMX512
data packet is a group of 512 data channels.
16-Bit DMX
To smooth out the movement of automated luminaires, the industry has adopted 16-bit DMX. This is not a change to
the DMX512 specification, rather a change in the way luminaires and consoles treat DMX512 information. In practice,
16-bit DMX adds a DMX512 channel each to pan and tilt - pan coarse, pan fine, tilt coarse, tilt fine, instead of just pan
and tilt. The console and luminaire combine these levels and increase the resolution of pan and tilt from 256 steps to
a theoretical maximum 65,536 steps at the console level, resulting in the ability to position the luminaire more
accurately.
