4. Connect a male terminator to the Data Out connector of the last fixture in the link

(see

Figure 1-11). For information on obtaining a terminator, see “Constructing a

Terminator” on page 1-11.

Note: Controllers, serial data distributors, data line optoisolators, and any

fixtures using the RS-422 DMX standard of serial communications

(including Dataflash

AF1000 xenon strobes, Intellabeam

fixtures,

and Emulator

laser simulators) block software uploads or crossloads

on a link. Therefore, make sure you either put all of these devices after

the Studio Spot 250 or Studio Color 250 fixtures on the link, or bypass

these devices when you perform software uploads or crossloads.

Constructing a Terminator

You must 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.

You can either purchase a terminator from your High End Systems dealer/distributor

(see

“Optional Accessories” on page intro-8), or you can follow the instructions below

to construct a terminator.

To construct a terminator:

1. Obtain a male 3-pin or 5-pin XLR

connector.

2. Disassemble the connector.

3. Solder a 120 ohm resistor, minimum of 1/4

watt, between pins two and three (see

Figure 1-12)

4. Reassemble the XLR connector.

Mounting the Fixture

Warnings: Equipment suitable for dry locations only. Do not expose

this equipment to rain or moisture.

Maintain a minimum distance of 1 m (3.28 ft.) from

combustible materials.
