Fuse Replacement

CAUTIOn! The ToughPAR™ Zoom RGBAW utilizes a high-output switch-

mode power supply with an internal fuse. Under normal operating

conditions, the fuse should not require replacement. The fuse is field

replaceable, however it is an advanced procedure suited to qualified

individuals. Should your ToughPAR™ Zoom RGBAW fuse require

replacement, please contact Blizzard Lighting for instructions, or to return

your unit for service.

Connecting A Bunch of ToughPAR™ Zoom RGBAW 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.

applications. 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
