19. extremely non standard data rates used by electronic control units on cars It also converts the logic level voltages present at the ports of PCs into the ones needed by car diagnostic bus systems It protects the PC from over voltage spikes that may be present on the car and that would otherwise damage the PC s ports It has protection against short circuits on any of its outputs so that if any of the diagnostic signal wires between the ECU and the Interface are accidentally shorted to ground or to 12 Volts then the Interface will protect itself against damage It will continue to work at raised voltages such as those present when a booster charger is used on a Car The Interface gets its power supply from the 12V present on the car s diagnostic socket When the Interface first has its power turned on it goes through a short power on test sequence You should see the Data LED blink twice briefly to confirm that the Interface is ready for operation For the more technically minded the Interface contains two PIC microcontrollers both clocked at 20MHz while spike protection is supplied by General Semiconductor TransZorbs Testing The Interface On The Bench It s already been mentioned above but it s worth repeating again the Interface gets its power supply from the vehicle under test This means that if you simply have the Interface connected to your PC via a serial cable you cant run any of the diagnostic
