3. SETUP

Fuse Replacement

With a flat head screwdriver, wedge the

fuse holder out of its housing. 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 ICE 30™eseses
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
