Cartek OBD Signal Converter Plug-In

INSTALLATION

Locate the car’s OBD socket which will be within 60cm (2ft) of the steering wheel. Insert the OBD Signal Converter then start the engine. If this is the first time the OBD Signal Converter has been installed then it may take a short while for it to interrogate the car’s OBD network and synchronize to the correct protocol. This will be indicated by a Red LED. Once the correct protocol has been determined then engine data will be extracted from the CAN-Bus network and converted into output signals. This will be indicated by a flashing Green LED.

OUTPUT SIGNALS

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).
