Data

DataTrack and DataTrack Backbone provide integrated wiring for DMX-512A (ANSI E.1.11)
and bidirectional RDM (ANSI E1.20-2010) control signals. The electrical specifications of these
DMX512A and RDM standards are based on ANSI/TIA/EIA-485-A-1998.
DMX512A standards require a continuous daisy-chain data-link topology with a terminating
switch or resistor with a value of 100–120 ohms to eliminate ringing and signal reflection. No
"Tees" or "Stars" are permitted.
Wire used for bringing the DMX signal into the track system must be Belden 9729 or
equivalent with shield connected to ground at one end, preferably the signal source.

Load Capacity

DataTrack and DataTrack Backbone distribute one or two 120V circuits (230V for EUTRAC
systems), up to 16A on a 20A circuit. Each circuit has an independent neutral for individual
control and a common ground.
• Maximum Feed: 2 x 20A branch circuits
• Maximum Load: 2 x 16A (2 x 1920W at 120V)
• Maximum Load for EUTRAC systems: 2 x 16A (2 x 4600W at 230V)
• Supply Wiring: 12 AWG (2.5 mm
The DataTrack Backbone fixture adapter has a load capacity of 300W (120V supply), or 600W
(230V supply) for EUTRAC systems.
