Default DMX512 Remote controlled LED

I'm having a problem with this circuit. I am trying to get an LED wash light circuit to be remote controlled via DMX512. The problem is, after I designed the circuit for the RS485 (which will deliver the DMX signal to my LED circuit) my professor told me that there's no time to make it and that I should just buy it. I couldn't find a descent one to buy. I am also not sure if I should connect the LEDs with parallels or using a darlington pair?

I have attached the circuitry for the RS485. Also, the options I have to connect the LEDs, not even sure which microcontroller is the best for them. Any help? It's also 5 - 9 LEDs.

I don't quite understand what types of LED's your trying to run and what for, but a simple SN7406 IC will run 8 LED's with the proper dropping resistors inline.

I will take a logic "1" on one input and turn on the attached LED in question on the corresponding open collector output, see the link to the info PDF on this IC chip.
