Fuse Replacement

LB Hex™ Unplugged utilizes a high-output switch-mode power supply with an
internal fuse. Under normal operating conditions, it should not require replace-
ment. Should the fuse require replacement, please contact us for instructions,
or to return your unit for service.
Connecting A Bunch of LB Hex™ Unplugged 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, con-
necting 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. 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.
3-Pin??? 5-Pin??? Huh?!?
If you use a controller with a 5-pin DMX output connector, you will need to use
a 5-pin to 3-pin adapter. If you'd like to build your own, the chart below details
a proper cable conversion:
