ICOM A introduction

ICOM A is a basic component.  Phisically, on one hand, it supplies the interface that connects with car OBD II diagnosing interface; on the other hand, it can supply the interface that is self-adaptable intergrated into garage.As protocal converter, it is responsible for testing and data exchange in different controling units, as well as signal processing through a high effective computer core. Electrical power pressure is supplied by vehicle interface. The lowest power pressure of Electrical operation of ICOM A is fixed to 8V. Only it exceeds the lowest value, can a stable function be guaranteed.

ICOM B introduction
ICOM B is the external MOST interface of ICOM A, and it conect with ICOM A by a usual USB or that within supplying. Power is supplied by USB through ICOM A. 

ICOM C introduction
ICOM C in an intelligent interface convertor, which makes OBD II compatible with BMW round plug. As a lenghened auxiliary module, it makes ICOM A conects with non-OBD II vehicle module. Power is supplied by round plug through KL30. 
The lowest pressure of ICOM C electrical running regulated to 8v. electrical pressure on KL30 is conveyed to OBD II through internal equipment, and then to ICOM A. Only when vehicle battery voltage ICOM C exceeds to the lowest limitation, can it guarantee the stable interactivity of the two equipments.
