RokBox 5 RGBAW Manual Rev. B

Fuse Replacement

The RokBox™ 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 the fuse require

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

your unit for service.

Connecting A Bunch of RokBox™ RGBAW Fixtures

You will need a serial data link to run light shows using a DMX-512 control-

ler 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.

plications. 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

Before replacing a fuse, disconnect the power cord.

ALWAYS replace with the same type and rating of fuse.
