Product Description
Mastertech Vehicle Communication
Interface Kit Components
The Mastertech Vehicle Communication Interface (VCI)
arrives in a kit which also contains a J1962 16/26 Pin
DLC Cable, 120VAC/12VDC, 1A Power Supply, USB
cable, cable keeper and the media containing diagnostic
application software (figure 1-1). A description of the
VCI hardware and software is included in the following
sections.
Figure 1-1. Mastertech Vehicle Communication Interface Kit
The VCI is used by professional technicians as an aid
in diagnosing and repairing automotive electrical and
electronic systems. The VCI is the connection between
the diagnostic software applications running on the PC
and a vehicle’s electrical and electronic systems.
For details about the diagnostics applications that are
compatible with the VCI, refer to the Bosch diagnostics
website; www.boschdiagnostics.net.
VCI Connections
For the location of the connectors for DC power and
vehicle communication on the VCI, see Figure 1-2.
For the location of the connectors for PC communication
on the VCI, see Figure 1-3.
Figure 1-2. Vehicle Connections to the VCI
Figure 1-3. PC Connections on the VCI
Figure 1-4. PC Standard Indicators (LEDs) and Power Button
For a description and location of the standard indicators
(LEDs) and the power button, see Figure 1-3.
Host Computer Interface
The VCI communicates with a host computer using three
possible interfaces between the VCI and the PC:
uUniversal Serial Bus (USB),
uLocal Area Network (LAN), and
uWireless Local Area Network (WLAN).
Universal Serial Bus (USB)
Note
The USB connection takes priority over
an ethernet or a WLAN connection. All
configuration changes or software updates
are only allowed using the USB connection.
Figure 1-5. USB is the first connection
The VCI has a fixed USB configuration (static IP address)
which cannot be changed. This ensures that the VCI can
always be connected to a PC running diagnostic software
and the VCI Manager application regardless of changes
to LAN or WLAN configurations required by the local
network. Refer to Using the VCI Manager application for
details.
The connectors on the USB cable are slip-in connectors
that do not securely lock in place. In order to keep the
USB cable connected, secure it to the VCI using the
supplied cable keeper. The cable keeper is attached to
the VCI case with a supplied 2.5 mm hex-head screw, the
USB cable is inserted into the slot, and then plugged in as
shown in Figure 1-6.
Figure 1-6. Securing the USB Cable
Local Area Network
(LAN)
A LAN consists of a two or
more computers connected
together using ethernet
cables. The connectors on
both ends of an ethernet
cable are latched. To disconnect them you must press
down on the latch while you pull the connector out.
The VCI’s LAN communication is setup and configured
as required for the user’s local area network using a PC
running the VCI Manager application. The VCI can be
networked using a Direct Connection (crossover ethernet
cable) or a network router (straight ethernet cable). A
brief description of each of these network configurations
follows.

Figure 1-7, above, shows a computer connected to a VCI
using a cross-over ethernet cable. In this configuration the
computer can communicate directly to the VCI. Most
computers have only a single network interface
connection so in this configuration you will only have
communication to the VCI. Refer to Enable Wired Ethernet
for details on configuring your VCI for communication on a
wired ethernet using a cross-over cable.
Note
A cross-over ethernet cable is required for LAN
Direct Connection. A cross-over cable is not
provided in the Mastertech VCI kit, but can be
purchased at your local computer store.
LAN with Network Router—Straight
Ethernet Cable
Figure 1-8. Connecting to VCIs on the Local Network through a
Network Router
Many offices and shops have computers connected
together using ethernet cables, network routers, and other
items such as printers and modems (internet connection
for email). Figure 1-8, shows one computer connected to
a network router which is then connected to two VCIs. In
an actual network there will typically be several computers
connected into network routers allowing any of the
computers to connect to and control one of the VCIs. Refer
to Enable Wired Ethernet for details on configuring your
VCI for communication on a wired ethernet.
Wireless Local Area Network (WLAN)
The VCI’s 802.11B/G WLAN connection is setup and
configured as required for the user’s local wireless network
using a PC running the VCI Manager application. The VCI
supports both Direct Connect (ad-hoc) and Access Point
wireless configurations. A brief description of each of these
wireless communication configurations follows.
Direct Connect (ad-hoc) Wireless
The ad-hoc wireless option allows you to network your
VCI wirelessly to a computer that has a wireless card and
diagnostic software. This type of connection is also known
as peer-to-peer or Direct Connect, and does not require
a network server or router. An ad-hoc connection may be
ideal for situations where you want to take a notebook
computer into the vehicle as you work with the VCI.
Figure 1-9. VCI Direct Connect Wireless
Note
Although an ad-hoc connection can be done
from the PC’s internal wireless card and the
VCI, Bosch recommends that the ad-hoc
connection between the PC and VCI be done
using a wireless USB adapter connected to
the PC.
The procedure for setting up ad-hoc wireless
communications requires two steps:
1. Use VCI Manager to configure your VCI interface. Refer
to Setup the VCI for Ad-Hoc Wireless Communication
for details.
2. Configure your wireless communications software
on your PC. Refer to Setup Your PC for Ad-Hoc
Communication for details.
Access Point Wireless—Infrastructure Mode
Note
Refer to your access point manual for network
configuration details and suggested operating
distances.
The access point wireless option allows you to connect
your VCI to a WLAN. Depending on the configuration of
your LAN, the communication through an access point can
allow you to access multiple VCIs from multiple PCs. You
must have an 802.11B/G Wireless Access Point connected
to your network within operating range of your work
area. Refer to Setup your VCI for Access Point Wireless
Communication (WLAN) for details.
Note
If you have any set up and connectivity issues
with your access point wireless configuration,
please work with your local IT to get it
resolved.

Setup Your PC for Direct Connection Wired Ethernet
Communication
Note
The following example will configure your
Toughbook PC for a direct connection using
a cross-over ethernet cable. This procedure
is not required if you are connecting your VCI
to a network router that your PC is already
communicating with.
Using the information, shown below, your PC can now be
connected using a cross-over ethernet cable to the VCI to
create a LAN of two devices.
Wired Ethernet State Enabled
Wired Ethernet DHCP/Static Static IP Assignment
Ethernet Hardware Address 00:90:7E:06:04:3F
Wired Ethernet IP Address 10.103.103.123
Wired Ethernet Netmask 255.255.255.0
This process, though essentially the same for any
laptop, will differ somewhat in the details depending
on the specific network interface (NIC) card installed in
your computer. The process described in the following
procedure is specific to the Bosch-recommended
Panasonic ToughBook, however the process should be
similar enough for any notebook PC that has ethernet
capability.
1. Using a cross-over ethernet cable, connect your VCI
and your laptop.
2. Power on both your VCI and your laptop.
After both have booted, the NIC card on the laptop will
see that a network ethernet cable is connected and
start requesting an IP address. (This assumes that the
NIC card is configured for DHCP service from an IP
network.) An icon in the Windows Task Bar will display
two tiny little computers with a message passing from
one to the other. If you place your cursor over this icon
you will see the message “Acquiring network address.”
Eventually, you should see the message “Limited or no
connectivity” as shown below.
3. Double-click
3. From the Windows Task Bar, double-click the Local
Area Connection icon.
Click Properties
4. Click the Properties button
Select Internet
Protocol
Click Properties
5. Select Internet Protocol [TCP/IP].
6. Then, click Properties.
7. Select Use
the following
IP address
8. Enter IP
address
10. Click OK
9. Enter Subnet
mask
7. Select Use the following IP address:
8. Enter the IP address. The IP address on your laptop
must be the same as the IP address on the VCI except
for the last group. In the above example, the VCI uses
123 for the last group while the laptop is using 001.
Note
An important thing to remember when
assigning IP addresses is that they must all be
unique. As long you are networking only your
laptop and your VCI, you can pick any two
numbers as described above. However, if your
laptop has a second ethernet connector or you
plan on connecting to a network using a USB-
to-ethernet adapter, then you must consider
the IP addresses on the entire network to avoid
addressing conflicts.
9. Enter the Subnet mask. The subnet mask on your
laptop must be the same as the subnet mask on the
VCI.
10.Click OK. Then close the remaining connection
windows.
Note
You must have a cross-over ethernet cable in
order for direct connect to work. A straight
through ethernet cable can be used if your PC
supports switching of the Tx and Rx lines.
