Standalone Fixture Linking; Terminating The Link - High End Systems Studio Command Series User Manual

CHAPTER 2
Setup and Configuration

Standalone Fixture Linking

To link one or more fixtures to a controller using either 3-pin or 5-pin XLR cables:
1. Connect the male XLR connector of a DMX Data cable to the Data Out connector on the
fixture addressed at DMX Start channel 1.
2. Connect the cable's female XLR connector to the Data In connector of the next fixture on
the DMX link.
3. Continue linking the remaining fixtures connecting a cable from the Data Out connector of
each fixture to the Data In connector of the next fixture on the link.
4. Connect a male terminator to the Data Out connector of the last fixture in the link. For
information on obtaining a terminator, see the following section.

Caution: Do not connect more than one Data In and one

Terminating the Link

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. If you plan to control your fixtures in stand-
alone mode (with no controller on the link), you must also install a female terminator in the
Data In cable connector on the master fixture (the fixture assigned to DMX start channel 1). A
terminator will prevent data reflection, which can corrupt the data communication on the link.
Use the following steps to construct a terminator.
1. Obtain and disassemble a 3-pin or 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.
