solution for Front(4)&Rear(4) sensors is:
2xPDC LED Sensor system(4 sensors, BOX where you connect sensors)
2xUSB interface board
1xPDC PIC LED v.1.00
1xPDC PIC LED v.1.10
Both USB boards must be wire connected NOT wireless. you must have specialy builded software plugin. CF plugin will have this included and maybe Standalone application PS Holmes will have choise which version would you like to start if Robby will add this...
