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.
