Constructing A Terminator; Mounting The Fixture; Figure 1-12. Data Cable Terminator - High End Systems Studio Spot 250 User Manual

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
and Emulator
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.
