Interface Features

Data Link Connector And Cable

The DLC cable supplied with your VCI is keyed
such that it will only connect to the VCI. It will
not connect to a Mastertech MTS 3100 or Tech
2 and conversely, Mastertech MTS 3100 or Tech
2 cables will not connect to the VCI..
Vehicle diagnostic information is passed between the PC
and the vehicle through the J1962 16/26-pin DLC cable
that is connected to the VCI.

Power Source

The VCI is intended to be powered from the vehicle
The VCI may also be powered using the 120VAC/12VDC,
1A Power Supply when located near a suitable
wall socket. See Figure 1-11. Typically you use the
120VAC/12VDC, 1A Power Supply during bench
operations when you are configuring the VCI
communications, updating software, and during testing of
the VCI.

Battery Operation

Four AAA Batteries are required to power the VCI during
brief power interruption.
The VCI will not operate solely on the batteries, the
VCI must be connected to the vehicle's 12-volt power
supply during testing or the 120VAC/12VDC, 1A Power
Supply during bench operations such as setting the VCI
configuration options or updating software.
See Chapter 4 for battery replacement instructions.


Five Light Emitting Diodes (LEDs), one red and four
green, are located on the front of the VCI as shown in
