4. Connect and set the DMX512 source
Connect the DMX512 signal source to the DMX input connector on the front of
the power supply using standard DMX cable. The DMX signal will be indicated by
a flashing green LED. The DMX signal will now position the gelstrings/vanes
according to their respective DMX signal levels.
Head-Feet Restrictions
The HEAD-FEET parameter is a method of accounting for the voltage drop in the
power/signal cable caused by the current drawn by each device.
To help understand this issue, think of it as water pressure (voltage) in a hose (cable)
where you have multiple water sprinkler heads (color changers). If the hose (cable) is
too long or you have too many sprinkler heads (color changers), the water pressure
(voltage) will be too low.
HEAD-FEET is defined as "the sum of cable lengths from each device to a single power
supply output".
Refer to the user manual of the specific components for detailed head-feet information
on those products.
