4.2.2. Function
The ICOM A is the basic component. Physically, it provides the interfaces for connection
to the vehicle OBD II diagnostic interface on the one hand and the interfaces for adaptive
integration into the workshop network on the other. A powerful computer core enables it to
work as a protocol converter to assume the data interchange between the tester and the
vehicle control units as well as the signal processing for connection of the measurement
system. The power supply is fed via KL30 across the vehicle interface.
The ICOM A is specified in electrical operation for a minimum voltage of 8 V. Stable
operation is only ensured if the power supply is above the minimum limit.
