Getting Started
This section covers all Tech 2 vehicle applications. Therefore, some of the information provided may not
be required for individual applications.
The Tech 2 contains two serial communication ports: the RS-232 and the RS-485. Use the RS-232 port for
downloading data from another computer to the Tech 2. The RS-485 port is currently not used.
The Tech 2 also contains two PCMCIA ports, a power jack connector, and a Vehicle Communications
Interface (VCI) connector. One of the PCMCIA slots contains a memory card with diagnostic information.
The power jack accepts power from the AC/DC power supply, battery, or cigarette lighter power cable. The
VCI connector accepts the DLC cable or DLC loopback adapter.
