Physical Specifications
The cable should not pass near any source of electrical noise such as
fluorescent circuits or motor wiring. Avoid close proximity to any AC
wiring. All control/power wiring must be in conduit.
Wire Recommendations
•
See the following table for recommended Wire Types
•
Use RS485 compatible cable for the communications. It is recommended that a
cable with 2 Twisted Pair, 24 AWG, stranded conductors be used. The spare pair is
for future uses.
•
Capacitance of wire shall be 15 pF/ft. or less
•
Nominal Impedance of wire shall be between 100-120 ohms
•
Drain/Shields to be tied together, insulated and grounded (on
one point
only)!
•
We strongly recommend the use of either Belden 9829, Belden 9729 or
Belden 8102 for the DMX wire runs.
The most effective way to insulate the drain/shield wire is to use a
piece of heat shrink tubing!
