Ok,

Just wondering who can help me out as there doesn't seem to be any docs.

I have J1SYS P2 connected to the PPD using all 4 outputs including 5V and then the PPD to a PPR-A connected via CAT5 and the output of that to a string of WS2811 LED's.

Now it works without using the Extenders but not with the Extenders and I have tried all 4 TX and Rx'ers.

Is there anything else I should be doing?

Thanks

Geoff
 
Lifted from Ed's site........
"Our first PPR can operate in several modes. The mode is setup with wire jumpers on a screw terminal strip on the board and the use of differing connections on the external connectors."Im guessing there isnt any documentation on how that jumper wire needs to be configured? I will email him and see if I can get some details.
 
Thanks Andy,


I did email him with the address on his website so hopefully I get an answer.

I think the different modes is just to do with the voltage out. I'm not using the +V as I have a separate power supply for the string.


Maybe it has some thing to do with being WS2811 as it doesn't use the clock. Does the extenders need a clock to work? If so then I have just wasted money.

Cheers
 
What model PPD are you using. The A,B or C.
What voltage is the connector on the P2 outputting to the PPD
 
I have 5000 ws2811 pixel modules connected in the same way as you have, I only use the P12R....

Things you can check;
Make sure the UTP is 1:1 straight.
Also play with the baudrate, I have 15mtr of UTP and a baudrate of 1800.
Check the lights again without the extender and make sure they work.
check this post: http://auschristmaslighting.com/forums/index.php?topic=5105.0 for some config info...
If things don't work post some pic's and schematics of your setup how things are connected and the extenders configured....

Hope this helps.

Greetings, Robert
 
Ok I have worked it out.


The following is what I needed to do:


1. Will not work with P2 supplying 5V as the regulator on the receiver needs a voltage higher then 5V so it can regulate down to the required 5V. I needed to change the jumper on the P2 to output 12V.
2. I needed a baudrate of at least 2000 to work, for some reason it didn't matter if I was using the Extender or connected directly I had to set the P2 to at least 2000, any less and the lights don't work.
3. Now the strange part, without the extenders I could only go around 4m when the P2 was set to 2000 baudrate and when I changed it to 3000 I managed to get 10m before I started having issues. Doesn't make sense as I thought the increase of baudrate would decrease the distance and not increase. I am going to do some more testing and see what length I can get at different buadrates.


Cheers
