ToughPAR RGBAW Manual Rev. B

3. SETUP

Fuse Replacement

CAUTION! The ToughPAR™ 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 fi eld

replaceable, however it is an advanced procedure suited to qualifi ed

individuals. Should your ToughPAR™ fuse require replacement, please

contact Blizzard Lighting for instructions, or to return your unit for

service.

Connecting A Bunch of ToughPAR™ 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 fi xtures set to sync in mas-

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

by all the fi xtures on a serial data link determines the number of fi x-

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 fi xtures 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 fi xtures on a serial data

link is 32 fi xtures.

Data/DMX Cabling
To link fi xtures 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 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
