OBD SIGNAL CONVERTER
Many aftermarket car accessories such as Gear Shift Lights, Tachometers or Digital Gear Displays require connection to electrical signals which are often not available on modern cars. The OBD Signal Converter from CARTEK simply plugs into the OBD (On Board Diagnostic) socket found on most modern cars and provides four useful signals by extracting and converting engine data from the car’s OBD port.
- RPM (Blue wire)
This is a 12v square wave signal where the frequency increases with engine speed. The signal outputs 2 pulses per crankshaft revolution
- SPEED (Green wire)
This is a 12v square wave signal where the frequency increases with road speed. The output frequency is approximately 2500 pulses per kilometer (1570 pulses per mile).
- ENGINE RUNNING (Grey wire)
This signal remains high (+12v) when the engine is stationary and is driven low (0v) when engine speed exceeds 350RPM.
- VEHICLE TRAVELING (Yellow wire)
This signal remains high (+12v) when the car is stationary and is driven low (0v) when road speed exceeds 9 Km/h (6mph).
