The following illustrations show examples of DMX data paths. These drawings are plan views, showing
the track system as if you were looking at it from above.
If you have additional DMX termination questions, please contact your local ETC representative.

Data transmission will become unreliable if DMX is not installed according to
standard protocols.
ETC recommends laying out the DMX data path for your track configuration BEFORE
ordering all track and couplers to ensure that no loops, stars, or Y's are created that
would disrupt data transmission.
The DMX data line is only for low voltage with an approximate value of 50V 2A
maximum.
If L-couplers, X-couplers, or T-couplers are required in your system, you may need to
disconnect one or more data-line connections to avoid data loops.
