Fuse Replacement
CAUTION!
The TOURnado™ CSI COB utilizes a high-output switch-
mode power supply with an internal fuse. Under normal operating condi-
tions, the fuse should not require replacement. The fuse is field replace
-
able, however it is an advanced procedure suited to qualified individuals.
Should your TOURnado™ CSI COB fuse require replacement, please con-
tact Blizzard Lighting for instructions, or to return your unit for service.
Connecting A Bunch of TOURnado™ CSI COB Fixtures
You will need a serial data link to run light shows using a DMX-512
controller or to run shows on two or more fixtures set to sync in master/
slave operating mode. The combined number of channels required by all
the fixtures on a serial data link determines the number of fixtures the
data link can support.
Fixtures on a serial data link must be daisy chained in one single line.
Also, connecting more than 32 fixtures on one serial data link without the
use of a DMX optically-isolated splitter may result in deterioration of the
digital DMX signal.
The maximum recommended cable-run distance is 500 meters (1640 ft).
The maximum recommended number of fixtures on a serial data link is
32 fixtures.
Data/DMX Cabling
To link fixtures together you’ll need data cables. You should use data-
grade cables that can carry a high quality signal and are less prone to
electromagnetic interference.
For instance, Belden© 9841 meets the specifications for EIA RS-485 ap
-
plications. Standard microphone cables will “probably” be OK, but note
that they cannot transmit DMX data as reliably over long distances. In
any event, the cable should have the following characteristics:
2-conductor twisted pair plus a shield
Maximum capacitance between conductors – 30 pF/ft.
Maximum capacitance between conductor & shield – 55 pF/ft.
Maximum resistance of 20 ohms / 1000 ft.
Nominal impedance 100 – 140 ohms
