Recommended Cable Types/Manufacturers
These are only a few of the suitable cable types. Any quality EIA485, twisted pair, 120 ohm, shielded
cable will also work.

Male Termination Connector
A male XLR termination connector is required at the last luminaire (or
“far end of the line”) to prevent signal reflections. Signal reflections may
cancel out the signal at certain line lengths, resulting in errors. The
terminator is also necessary for software downloads and running tests on
multiple luminaires.
To construct your own connector, you will need the
following components:
•
5-pin, male XLR connector.
• Two 1/4W 5% 120 ohm resistors.
Note: A male termination connector is also available as an accessory from Vari-Lite. See
“Replacement Items/Accessories” on page 6 .
