3. SETUP

With a philips head screwdriver, unscrew the fuse holder from its hous-

ing. Remove the damaged fuse from its holder and replace with exact

same type fuse. Insert the fuse holder back in its place and reconnect

power.

Connecting A Bunch of PixelStorm™ 240 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 mas-

ter/slave operating mode. The combined number of channels required

by all the fixtures on a serial data link determines the number of fix-

tures 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

applications. Standard microphone cables will "probably" be OK, but

note that they cannot transmit DMX data as reliably over long distanc-

es. 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
