Troubleshooting
Symptom Solution
Fixture Auto-Shut
Off
Check the fan in the fi xture. If it is stopped or moving slower than
normal, the unit may have shut itself off due to high heat. This is to
protect the fi xture from overheating. Clear the fan of obstructions, or
return the unit for service.
Beam is Dim Check optical system and clean excess dust/grime. Also ensure that
the 220V/110V switch is in the correct position, if applicable.
No Light Output Check to ensure fi xture is operating under correct mode, IE sound ac-
tive/auto/DMX/Etc., if applicable. Contact service for more info.
Chase Speed Too
Fast/Slow
Check to ensure proper setup of speed adjustment.
No Power Check fuse, AC cord and circuit for malfunction.
Slow Movement Check that speed channels are set appropriately.
No Response to
Audio
Verify that the fi xture is in “Sound Active” mode.
Adjust Audio Sensitivity, If Applicable.
Fixture Not
Responding /
Responding Errati-
cally
Make sure all connectors are seated properly and securely.
Use Only DMX Cables.
Install a Terminator.
Check all cables for defects.
Reset fi xture(s).
If your problem isn’t listed, or if problems persist,

3. SETUP
Fuse Replacement
CAUTION! The RokPix™ 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 RokPix™ fuse require replacement, please contact Blizzard
Lighting for instructions, or to return your unit for service.
Connecting A Bunch of RokPix™ 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.
For instance, Belden© 9841 meets the specifi cations 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
