Connecting to the Vehicle


Connecting to the vehicle (Serial RS232 Interface)

  1. Connect the female side of the black serial interface cable to the laptop 9 pin connector.
  2. Connect the male side of the black serial interface cable to the female connector on the interface unit.
  3. Connect the 9 pin side of the OBDII interface cable to the male connector on the interface unit.
  4. Connect the 16 pin side of the OBDII interface cable to the vehicles diagnostic port when you are ready to scan or reprogram the vehicle.


Connecting to the vehicle (USB Interface)

  1. Connect one end of the USB interface cable to the laptop USB connector and the other end to the interface unit.
  2. Connect the 15 pin side of the OBDII interface cable to the male connector on the interface unit.
  3. Connect the 16 pin side of the OBDII interface cable to the vehicles diagnostic port when you are ready to scan or reprogram the vehicle.



Standard Vehicle Interface Unit

Your vehicle interface is an intelligent microprocessor controlled unit. It converts vehicle "talk” to laptop “talk” (protocol converter).

The interface unit is a precision device in rugged design and will provide years of trouble free use. This does not mean your interface can handle all situations. Never expose the unit to water excessive heat or moisture. Never drop or hang the unit by the cables.
Static electricity can damage the unit or cause malfunctions. Always discharge yourself to the vehicle chassis (door, steering column, etc) before connecting or disconnecting the interface unit. While we have done our best to provide static protection, there is no benefit in continually testing this protection.


Enhanced Input/Output (EIO) Vehicle Interface Unit

Your vehicle interface is an intelligent microprocessor controlled unit. It converts vehicle "talk” to laptop “talk” (protocol converter) and also read 4 analog inputs and control two outputs simultaneously. These enhanced real time features are designed work with the VCM Scanner program. Each channels function is configured by the user in the VCM Scanner program. Any analog input can be configured to become a number of different data types in the scanner.

The device output control will operate relays, lights or a combination of both.
Turning on an output is configured in the scanner by choosing an engine variable or A/D channel and setting the conditions for on/off.
Please see the VCM Scanner Enhanced IO section for more information on how to configure these settings.

The interface unit is a precision device in rugged design and will provide years of trouble free use. This does not mean your interface can handle all situations. Never expose the unit to water excessive heat or moisture. Never drop or hang the unit by the cables.
Plug and unplug the cables by holding the connectors, not the wires.
Static electricity can damage the unit or cause malfunctions. When the enhanced IO connection is not in use, always keep the protection plug in place to avoid damaging the pins.
Always discharge yourself to the vehicle chassis (door, steering column, etc) before connecting or disconnecting the interface unit. While we have done our best to provide static protection, there is no benefit in continually testing this protection
