Setup and Configuration
10 DL.3 Digital Light User Manual
3. Tighten the clamps firmly to the fixture’s base
and to the support.
4. Run the safety cable through the loop on the
fixture’s base, and around the truss.

Note: High End Systems does not recommend

operating the DL.3 fixture with the base

perpendicular to the stage floor (fixture

mounted sideways). Side mounting will

result in significantly decreased lamp

life.

Linking DL.3 Fixtures
DL.3 fixture s should be li nked to a sta ndard DMX512 link for control by a DMX desk as well as a
Ethernet fixture link for CMA functions.

Setting up a Standard DMX Link

The number of fixtures on a link will be determined by the combined number of channels
required by all the fixtures. The DMX channel range of a DL.3 fixture is determined by the
protocol mode you choose.
DL.3 Standard Protocol = 170 channels
DL.3 Dual Protocol = 132 channels
Single Protocol = 94 channels
Use data-grade cable and 5-pin XLR cable connectors. For cable and connector specification, see
“Cables and Connectors” on page D-305.
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.
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.
