Linking trackspot Bolt Fixtures
The trackspot Bolt fixture operates on standard DMX512 link controlled by a DMX console. The
number of fixtures on a link will be determined by the combined number of channels required by
all the fixtures. A trackspot Bolt fixture requires a 21-channel footprint on a standard DMX512
link.
Cable Connectors
Use data-grade cable and 5-pin XLR cable connectors to attach your fixture to the DMX link.
The trackspot Bolt 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.
Test each cable with a voltage/ohm meter (VOM) to verify correct polarity and to make sure
that the negative and positive pins are not grounded or shorted to the shield or to each other.
CAUTION! Do not connect anything to the ground lug on the XLR
connectors. Do not connect or allow contact between the common
(cable shield) and the fixture’s chassis ground. Grounding the common
could cause a ground loop and/or erratic behavior.
