Data Connection
Note: Fixtures on a serial data link must be daisy chained in one single line. To comply with
the EIA-485 standard, no more than 32 miniature data enablers should be connected on
one data link. Connecting more than 32 miniature data enablers on one serial data link
without the use of a DMX optically-isolated splitter may result in deterioration of the digital
DMX signal.
Maximum recommended serial data link distance: 500 m (1640 ft)
Maximum recommended number of fixtures on a serial data link: 32
DMX Data Cable
If installer prefers 3-wire data cables, we suggest a Belden© 9481 or equivalent cable which meets
the specifications for EIA RS-485 applications (Use PCL002 DMX hardwiring DMX coupler).
Standard microphone cables cannot transmit DMX data reliably over long distances. The cable
must have the following characteristics:
Type: shielded, 2-conductor twisted pair
Maximum capacitance between conductors:
30 pF/ft
Maximum capacitance between conductor and shield:
55 pF/ft
Maximum resistance: 20 ohms/1000ft
Normal impendance: 100 ~ 140 ohms
If installer prefers a RJ45/CAT5 installation, a RJ45 jack can be used (use PCL004 RJ45
coupler).
Note: To comply with all local codes and jurisdiction, qualified communications technicians must do
communications wiring.
Note: Communication cables and AC power lines must not be run in the same conduit.
A. Route Data Cables in series between miniature data enablers and any communications
accessories using DATA IN and DATA OUT.
B. In order that they may be easily accessed from the room once construction is complete,
secure data cables in the immediate proximity of the miniature data enablers.
Coloronix strongly recommends clearly marking communication cables in such a way to indicate
the correct order of connection.
C. Use RJ45 DMX terminator, insert in “DATA OUT” of last fixture in series.
Note: To avoid signal transmission problems and interference, it is always advisable to connect to a
DMX signal terminator at the end of the run.
