Remedies
No status light on
product.
Power supply issue,
such as blown fuse,
faulty connector or
damaged cable.
Ensure that the mains supply is connected
to the junction box and supplying power to
the product.
Check all power connections and cables.
Connected fixtures
do not respond to
control.
Fault in the control
network due to wiring
problem, connector or
cable damaged, or
incorrect DMX
addressing, or
potential interference
from proximity to a high
voltage installation.
Check if the product status LED is flashing
red to show that control data is not being
received, and if so, check all DMX cables
and connections to ensure the integrity of
the physical network.
Ensure that the DMX network is terminated.
Check that the components in the DMX
network all use standard DMX polarity.
Ensure that the fixtures are set to the
correct DMX address, one that matches
that set on the DMX control device.
Check the pins on the connectors from the
previous product in the DMX network.
Attempt to control the product with another
DMX control device.
Move the product if it is being operated very
close to an unshielded high-voltage
installation.
