my new rgb modules ready now , i wanted to use john project but i changed PIC with 16F628A , i used PIC in my dmx512 rgb module and i can set dmx address with dipSW , its cost more expenciveden WS2801 but beetter to use for common projects with address change and make same address , i made 1190 Module and it is 1190 * 3 = 3570 dmx channel , i decided to use vixen for my project but i will need 512 x 7 output for all RGB modules , which plugin from vixen i can use for this modules and what kind of interface i must make with 7 x 512 out ? which interface vixen support like this ?

You built 1190 of these already? That was fast!

Where's your DMX connectivity? I see an address switch, power input, and RGB output, but no DMX I/O...

yes i made 1190 pcs like this , pcb is easy to make , in 1 day they can make 1000 if i need , you can see SN75176 IC near PIC right side and before 7805 :) on pcb and also + / - and GND letter too for dmx cable , i didnt put sn75176 yet i will tomorrow .

Are there any parts on the reverse side of the PCB?

Also if these are pixel, why such large transistor on the output?
I take it you have already coded the PICs. care to share your code?

large transistor because i have 12 leds in my pxls , yes there are some parts more under pcb too ,no i didnt code my pic yet because i still think about what kind of i can use to control so much pxls from computer , i look for interface with 7 x 512 output to control all pxls maybe i can use this http://www.j1sys.com/ecg-dmxren8/

you seem to be have difficulty understanding all you need is 7 DMX universes.

3 options here are:
Hardware:
http://www.j1sys.com/ecg-dmxren8/

or
RPM has developed a USB to DMX dongle you will need 7, http://doityourselfchristmas.com/forums/showthread.php?7009-USB-to-DMX-dongle-Enttec-Pro-compatible

or
jstjohnz has done a 4x DMX controller before swinging over to pixels. http://doityourselfchristmas.com/forums/showthread.php?12444-A-DMX-controller-for-multiple-RGB-pixel-strings&p=127494#post127494

Thank you Matt_Edwards , i decided to make ECG-DMXRen8 board , i can have 8 x 512dmx output and can control my systems , i will try it and share news here
