Connecting to the Link
To link one or more fixtures to a DMX controller:
1. Connect the male XLR connector of a DMX Data cable to the controller’s DMX Data Out
connector.
2. Connect the Data cable’s female XLR connector to the Data In connector of the first (or
next) fixture on the DMX link.
3. Continue linking the remaining fixtures connecting a cable from the Data Out connector of
each fixture to the Data In connector of the next fixture on the link.
4. Terminate the link by installing a 120 ohm, 1/4 watt (minimum) terminator in the fixture’s
Data Out (female) cable connector in the last fixture on each DMX link. A terminator on the
last fixture of the link prevents data reflection, which can corrupt the data communication
on the link.
