4. Connect a male terminator to the Data Out connector of the last fixture in the
link. For information on obtaining a terminator, see “Optional Accessories” on
page 1-2.
Installing a Terminator
Install 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.
Purchase a terminator from a High End Systems dealer/distributor (see “Optional
Accessories” on page 1-2), or follow the instructions below to construct a terminator.
To construct a terminator:
1. Disassemble a male 5-pin XLR connector.
2. Solder a 120 ohm resistor, minimum of 1/4
watt, between pins two and three.
3. Reassemble the XLR connector
Powering On the Fixture
Caution: Do not power on the fixture until verifying that the line cord cap
is suitable for the power source in your location.
Warning: This equipment for connection to a branch circuit having a
maximum overload protection of 20 A.
To power on the DL.1 fixture, simply connect it to an appropriately-rated power
source and turn the power switch located on the rear of the fixture to the ON (|)
position. After being connected, controller commands can remotely power up or
shutdown the fixture, (see “Control Function Options” on page 4-4 in the Standard
Protocol table.) before performing procedures that require the fixture to be
disconnected from power.
Homing the Fixture
When the DL.1 fixture is connected to an appropriately-rated power source, it
automatically begins a homing procedure to verify that the major functions of the
fixture and projector are oriented properly. The initial homing ends with the display
in the Menu Locked mode.
