applied) connected to the diagnostic adapter, the LED "24V" will go on.
The diagnostic adapter is now powered by the heater with 24V. Because
the diagnostic adapter features a galvanic isolation to protect the
computer, power supply from the computer is also required. That
happens in the moment you connect the diagnostic adapter to your PC
using the supplied with the adapter USB cable. The LED "PC" signals a
connection to the PC. The LED "BUSY" signals you bidirectional activi-
ties of the data line. This light flashes with very short pulses.
