ECG-P2 ethernet directly to computer

Oh yes sorry, took me a while to figure that out too.

Glad you got it sorted. I always find it easier to start with the recommended and make changes from there. Good luck with your lights

thanks, any tips or lessons learned that i need to be aware of?

 

[BrianJ]

they only thing I know of is that you need to make sure you add power to your lights after the P2 as it is not designed for any real current output. Trying to drive to many lights will cause issues.

ok thanks, i was just trying to find the post with the diagram so i get it right.

 

[ShellNZ]

Not really, I have my 2811 stuff speed set to 2400 and I also have a 1812 strip and have set that to 2000. Both work great at that speed (2400 flickered sometimes on the 1812 so lowered it).

Just make sure you enable E1.31 and also tick UBL enabled (in IP configuration part of P2 config page). Not 100% sure of what Artnet is so that is unticked in mine.

If it turns out your strip is diff to RGB you can change the order in the P2 setup, tis great.

ok i have the ws2811IC strips but i only see one cable for data so do I only run the data wire from the P2? Or do i combine the data and clock from the p2 and connect it to the data on the strip?

 

[BrianJ]

the 2811 does not use a clock wire, just power, ground, and data

 

[ShellNZ]

Data from the P2 goes to data (DIN) on the strip. Clock is not used on the WS2811.

Then you have +12V from the strip to + on the PSU (not the P2).

Then you also have the GND that goes to P2 GND and another cable going from -ve on the PSU to GND of P2 as well.

 

[yzguy96]

there are 2 grounds on the ws2811ic do i just need to hook up the ground from the power supply with the ground coming from the P2 with one of the grounds on the 2811 strip or both?

 

[ShellNZ]

Just one, the other one is for any power injection that you may need.

 

[yzguy96]

ok so hook the ground from the PS and the P2 together then connect it to the ground on the 2811 strip instead of the ground that is connected with the data?

This diagram may be of some assistance

thanks, i saw this diagram but the clock wire threw my off...i did buy some of ray wu 3 core pig tails but they were in Europe wire format and i did not want to assume what the red, blue, green are for?

 

[fasteddy]

The wire colours basically there to diferntiate the wires, so regardless of the colour make sure you keep with the same wires you choose with all your connections.

I use

Brown for +V,
Blue for Gnd
yellow/green for data.
