Fuse Replacement

With a flat head screwdriver, wedge the fuse
holder out of its housing. Remove the damaged
fuse from its holder and replace with exact same
type fuse.

Connecting A Bunch of SPOTMAN's

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.
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. 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.
