Connecting to control data
The system diagrams available in the DOWNLOADS section of the Exterior Wash Pro pages on the
Martin website at www.martin.com will also help with planning the installation layout.
A DMX512 data link is required in order to control the fixture via DMX (and manage fixtures via RDM,
if used). Your Martin® supplier will be happy to help if you need advice or assistance in planning the
link.
Important! Protect all connections and all breaks in cable jackets from moisture (see 'Protecting
connections from moisture' on page 36).
The fixture has a 2 m (6.4 ft.) cable tail with two pairs of data conductors and two shield wires for data
connection. See below.

Do not connect either of the shield conductors to ground (earth) or allow a shield conductor to come
into contact with a connector shell, as this may cause interference.
You can connect the fixture's data cable tails to a DMX/RDM data link using screw terminals, quick
connectors or soldered joints in junction boxes or using XLR connectors that are suitable for the
environment. Ensure that the fixture is protected from the entry of water via the data cable by using
junction boxes or connectors that are protected to IP67 or higher. Fill junction boxes with potting
compound.
