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 available as an accessory from Vari-Lite. See
“Accessories” on page 8.
Loopback Connector
When transferring software versions from luminaire to
luminaire, a loopback connector is required at the first luminaire
in the data link.
To construct your own connector, you will need the following
components:
• 5-pin, female XLR connector.
• Two small segments of 22AWG wire.
Note: A loopback connector is available as an accessory from Vari-Lite. See
“Accessories” on page 8.
