3. SETUP

Remove the fuse holder from of its housing. Then take out the damaged fuse

from its holder and replace with exact same type of fuse. Reattach the fuse

holder, and then reconnect power.

Connecting A Bunch of Verismo™ Fresnel Fixtures

You can use a serial data link to run light shows when using a DMX-512

controller with two or more fixtures. 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.

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 distances. 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

Before replacing the fuse, disconnect the power cord.

ALWAYS replace it with the same type and rating.
