4.  POWER SUPPLIES
Power up the Tech 2 using either: 
• The power jack connector at the bottom of the Tech 2 unit (Figure 4-1), or 
• The DLC cable power jack connector behind the area where various DLC adapters are connected 
(Figure 4-1). 
For non-vehicle communications, connect the 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 the power source is connected directly to the Tech 2. 
When the Tech 2 is connected to the DLC of an appropriate vehicle, the vehicle 
battery supplies power. When the Tech 2 is not connected to the vehicles DLC, the 
DLC cable power jack connector accepts power from the following: 
• Cigarette lighter power cable (Figure 4-1, see text below) 
• Battery power cable (Figure 4-1, see text below) 
• NAO power supply (Figure 4-1 and Figure 4-2, see NAO Power Supply on page 3) 
If the DLC and external power source are both connected, the power jack connection supplies current to the 
Tech 2. In this instance, power from the vehicles DLC connector is automatically disconnected from the 
Tech 2 internal power supply. 
CIGARETTE LIGHTER POWER CABLE 
This cable contains one fuse and two connectors. It has a cigarette lighter plug at one end and a power jack at 
the other (Figure 4-1). The power jack connects to the Tech 2 DLC cable and carries power to the Tech 2 
when the selected vehicle adapter does not provide power.

BATTERY POWER CABLE 
This cable has red and black battery clamps attached to one end and a power jack to the other (Figure 4-1). 
The power jack connects to the Tech 2 DLC cable and carries current to the Tech 2 when the selected 
vehicle adapter does not provide power and there is no cigarette lighter adapter available.
NOTE
This cable contains two 3-amp fuses. If you need to replace them, use 
identical 3-amp fuses. See Chapter 6 for information on fuse replacement.

NAO POWER SUPPLY 
North American electrical supply is normally 110 volts. The Tech 2 base kit includes an external AC to DC 
power supply with 110 V AC/60 Hz input (Figure 4-2). Output is 12 volts at 1.5 amps.
CAUTION
CAUTION!To avoid personal injury due to electric shock, use a grounded outlet only. 
The NAO power supply is for North American use only. These devices are 
intended for indoor use only.

5.  ADAPTERS
A number of adapters are available for the Tech 2 which allow connection to many different vehicles 
(Ta b l e 5 - 1 ,  Tech 2 Adapters). Specific adapters are included in the Tech 2 base kit depending upon Tech 2 
configuration
—NAO. Adapters not included in the base kit may be purchased separately from Vetronix. 
DLC CABLE 
The DLC cable (P/N 02002952) has a 26-pin connector with thumb screws at one end that connects to the 
Tech 2s VCI cable connector. At the other end is a 19-pin connector that connects to a variety of adapters 
(Figure 5-1 and Figure 5-2).
