Power Supplies
Power up the Tech2 using either:
• The power jack connector at the bottom of the Tech2 unit, or
• The DLC cable power jack connector behind the area where various DLC adapters are
connected.
For non-vehicle communications, connect power source to either location.
For vehicle communications, connect the power source to the DLC cable power jack
connector only. Proper grounding may not be present if power source is connected directly
to Tech2.
When the Tech2 is connected to the DLC of an appropriate vehicle, the vehicle battery
supplies power. When the Tech2
is not connected to the vehicle’s DLC, the DLC cable
power jack connector accepts power from the following:
• Cigarette lighter power cable
• Battery power cable
• NAO or Universal power supply
If the DLC and external power source are both connected, the power jack connection
supplies current to the Tech2
. In this instance, power from the vehicle’s DLC connector is
automatically disconnected from the Tech2 internal power supply.
