    Hello, I purchased and received my pixel extenders from J1sys today. However there is no documentation with them and I have no idea how the jumpers should be set up. I have a 12vdc setup with ws 2811 strip lights approx. 60 feet away. Power injection has been added with thicker cable. I need to know jumper setup of these devices. Does anyone have experience with these? THanks Chris

    I asked the same thing several months ago but never got a good answer. I think they are set up for 5v but I understand they can do 12v.

    Shell, I think Chris and Larry are talking about Ed's pixel extenders (http://www.j1sys.com/ecg-ppx/) , as opposed to the P2.

    Here are a couple threads that should help:

    I have a set of these that I never bothered playing with - I think I grabbed them with an order of something else, just in case I needed them. I probably should play with them at some point!

    Below is some text I got from ed.
    also attached are the chematics I got from him.

    Kind regards, Robert
    (edit 18-jan, fixed attachments)

    The PPR-A:
    RJ1 is the input via a PPX cable as described in the PPX documents.
    P1 is a 2 x 1 x 4 3.5mm connector.
    The top row of P1 is pins 1-4 and is used to jumper the incoming voltage over to the power control block or the 5V from the power control block to the pixel power lead. It has a ground (pin 1), the PXX voltage (pin 2), a connection to the board +5vdc bus (pin 3), and the connection to the pixel power output (pin 4). In simple mode, as shipped, a jumper from pin 3 to pin 4 places the board 5v supply on the pixel output power. but you can use it in other ways. If you have an external supply you can use it to inject power into the board. If you want to use a higher power external 5v dc-dc converter you can connect it to use the gnd, PPX+V for inputs and output the 5V on 5V and pixel output. If you want to use a different voltage (12v) then you can use gnd, PPX+V, and the pixel output.
    The bottom row of P1 is pins 5-8 and uses our standard ground,clock,data,power pinout.
    P2 determines the use of the optional onboard regulator and interconnection of the 5VDC supply. In its usual mode, as shipped, we take the PPX+V and input it to the regulator, the 5vdc output is then connected to the board 5vdc bus. This is done with jumpers on pin 2/3 and pin 4/5. If the PPX is higher than 36V the user could use an external dc-dc converter on P1 to get the pixel power down to 12V or 24v or something and then input the pixel power (pin 1) into the regulator (pin 3).

    Thanks for the help everyone. Im still a bit confused on the receiver end though. I am using a 12vdc supply. could someone verify jumper selection for me? Thanks Chris
