hi everyone jordan from integ here with the recent release of the new cvc4 we thought we
put together a couple of videos exploring some of the features of the cvc4 and why they make
it a really neat and powerful led driver today we'll discuss what p-link is how it's different
to other forms of data that you may be familiar with and how this core feature overcomes some
of the limitations associated with traditional dmx control p-link data is an n-tec only protocol that
we came up with to control pixel and non-pixel led controllers now if you're already familiar
with ntec control solutions you may have already come across p-link data in the form of a pixelator
system p-link is the data that goes from your pixelator or pixelator mini into your
p-link injector in this use case it's employed to control a pixel lighting system like pixel tape
or dots like our new spxl40 system it's similar to dmx but has a few differences that we can see
highlighted by the new cvc4 the cvc4 is meant to control constant voltage rgb or rgbw led
table panels it receives data via dmx or p-link and it receives dc power from a regulated supply
once you've provided data and power to the cvc4 it will begin to control the power output to
your leds using pwm so in this respect it's quite similar to a regular dmx controller
in fact if you wire it up with dmx it works exactly like a dmx decoder
you can daisy chain these units at the input port by splitting off a dmx line at the terminal
and running it to other units if you choose to control your cvc4 like this you'll be subject
to the limitations of dmx that is you can only connect a maximum of 32 of these devices per chain
if you have to do more than that you have to start running a new dmx universe meaning another cable
run or you have to use a splitter meaning a higher equipment cost regardless of how many
universes that you want to use you'll need to make sure that you wire up a dmx terminator
at the end of every dmx line you also need to make sure that you manually address every cvc4 via
rdm if you want them to act independently let's have a look at a hybrid dmx peeling system next
in this system we have dmx coming into the first cdc-4 then p-link data daisy chaining between the
cvc4s after that right here is where you see some of the main differences between p-link and dmx
when daisy-chaining with p-link data you're not limited to 32 devices per chain
this means there's no need for extra dmx universes or physical outputs or cable
runs from your controller or a splitter just to get more out of that one universe
now we can use a whole dmx universe without the need for a splitter and conveniently we don't
need to use a dmx terminator and the cvc4s will auto address down the line now let's have a look
at a full p-link system here we have p-link data coming into the first cvc4 from a pixelator or
pixelator mini controller just like in the hybrid system we're not limited to 32 devices per chain
in fact with p-link we can support up to two universes daisy-chained together
that's up to 340 cvc4s chained together without needing splitters terminators or addressing
so there you have it p-link data explained it's a little bit like dmx
but with a few neat little changes that make it way more friendly for larger installations where
you might need hundreds or even thousands of cvc4s well that's it for today's video
