Linking the Fixtures

X.SpotXtreme fixtures can be linked to other fixtures on a standard DMX 512 link
and then be controlled by the first fixture on the link or a DMX controller.
The number of fixtures on a link will be determined by the combined number of
channels required by all the fixtures. The standard configuration for an
x.SpotXtreme fixture requires 38 channels on a DMX 512 link.
When connecting more than 32 fixtures to a link, use a DMX splitter. The 32 device
limit complies with the EIA-485 standard. Connecting more than 32 devices per link
without a DMX splitter will eventually deteriorate the digital signal.
Controllers, serial data distributors, data line optoisolators, and any fixtures using
the RS-422 DMX standard of serial communications (including Dataflash
xenon strobes, and Intellabeam
TalkBack™ protocol on a link. Therefore, make sure to either put all of these devices
after the x.Spot®Xtreme fixture on the link, or bypass these devices when
performing software uploads or crossloads.

Data Cabling and Connectors

To link one or more fixtures to a controller and/or to each other, obtain data cabling.
Cabling can be purchased from High End Systems (see "Optional Accessories" on
page 1-4) or constructed.
High End Systems recommends data-grade cable. Data-grade cable is designed to
carry a high-quality signal with less susceptibility to electromagnetic interference.

DMX Data Cables

®
Use Belden 9842 or equivalent (meets specifications for EIA RS-485 applications)
data cables with the following characteristics:
• Two twisted pairs (4-conductors) plus a shield
• Maximum capacitance between conductors: <15 pF/ft.
• Maximum capacitance between conductor and shield: 55 pF/ft.
• Maximum resistance: 20
• Nominal impedance: 120

Cable Connectors

The x.SpotXtreme fixture accepts 5-pin XLR cable connectors. Cabling must have a
male XLR connector on one end of the cable and a female XLR connector on the
other end.
Pin one is the common (cable shield), pin two is the data complement (negative), pin
three is the data true (positive). Pins four and five are not used, but they allow a
secondary data link to pass through the fixture, (see Figure 2-4).
