DMX512 Pixel LED Controller ( UCS512C4)

Dear All

I have Pixel LED module which has 6LED which control UCS512C4 IC . This is addressable programmable module even using Arduino , I serched google to find out datasheet for UCS512C4 but I could not find it

1 Please help to findout the datasheet

  1. The module has following pins

GND
PI
PO
A
B
24+

I need to understand the operation of above pins

GND 24+ ( Power Supply Pins)
PI - data in
PO Data Out

A and B is unknown by me

Please advice

Please see the attached image for more details

A/B are the RS485 data lines used to deliver the DMX512 data. No idea about PI/PO but would assume they are used for daisy chaining several of these modules together and are input (PI) and output (PO). They could just be for power as anything I can find on the UCS512 seem to indicate it needs 5V or they could be for programming the DMX address of the modules.
