Getting Started
This section covers all Tech2 vehicle applications. Therefore, some of the information
provided may not be required for individual applications.
The Tech2 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 Tech2. The RS-485 port is
currently not used.
The Tech2 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.
Notice:
When using the Tech2 for vehicle communications, the power jack must be
connected to the Tech2 DLC loopback adapter
