Planning the Track Layout
Consider the following elements as you plan your track layout:
• Track orientation: Each piece of DataTrack has a top and a bottom.
• Conduit entry points: Each piece has limited available conduit knockouts.
• Data paths and termination locations: Plan the DMX data paths before installation. DMX data
paths must be contiguous daisy chains with terminations. Stars, loops, or Y’s will result in faulty
performance of DMX fixtures.
• Coupler and Track Connections: Couplers will only fit into DataTrack in one orientation. The
ground/data bus connection of the coupler must mate with the ground/data bus portion of the
track. This is important to keep in mind when purchasing couplers (ground left versus ground
right, ground inside versus ground outside). All product references to ground orientation also
refer to data bus orientation, as illustrated below.
