The purpose of a Data Link Adapter (DLA) is implied by its name: it is an adapter
that provides a link between two different data networks or protocols. The Parker
Vansco DLA provides the link between a PC and an automotive network.
Information from the engine and transmission is converted into a format that a
laptop can understand. The DLA transfers data from computer ports (USB) to
vehicle ports (J1939, J1708).
The Data Link Adapter is sold in kit form, with all of the necessary cables and
connectors included. This manual explains the contents of the kit, and how to set up
and use the DLA for USB communication.
3.1. Contents of USB-DLA kit

5.1. Plug in the USB cable
Connect the DLA to your computer using the USB cable provided. Plug the A-type
receptacle into the back of your computer (1), and the B-type receptacle into the
DLA (2). You should hear a Windows alert every time the DLA is connected or
disconnected.
iINFORMATION
The DLA is considered a high current device because it draws more than 100mA
when operating. The unit must be plugged directly into your PC, or into a powered
USB hub. It will not operate if plugged into an un-powered USB hub.
Figure 6: Connect DLA to PC

USB Data Link Adapter 14
Using the USB-DLA
5.1.1. Load the USB drivers
The USB-DLA will be detected automatically when it is plugged into your laptop.
The first time the device appears on a USB port, Windows will launch the Found New
Hardware Wizard in order to load the USB drivers. Windows will do this every time
the device appears on a new USB port (e.g., if you attach the USB-DLA to a new hub,
Windows will want to install the driver for each port on the hub). The USB drivers are
loaded like any other USB device. The following example shows how the drivers are
loaded in Windows XP. Select Install the software automatically (Recommended)
and click Next.

Using the USB-DLA
5.2. Plug in the vehicle interface cable
Connect the DLA to the vehicle using the vehicle interface cable provided. This cable
is typically a DB-15 (3) connected to a 9-pin Deutsch (4). Note that the vehicle
connector may change depending on the preference of the vehicle manufacturer.
Figure 10: Connect USB-DLA to vehicle
CAUTION
The USB ground is not isolated from the power ground. A computer connected to
the USB port must be electrically floating and not have any connections to the
outside world, including the AC power adapter and the serial port. Failure to
observe this may result in damage to the DLA and the computer USB port. If a
laptop battery needs to be charged, the USB port must be disconnected from the
DLA. If the DLA is to be used with a desktop computer, care must be taken to ensure
that the power supply to the DLA is isolated from any earth or vehicle ground.
5.3. USB-DLA LED Indicators
The USB-DLA has 3 LEDs for status indication. The LED indicators on the USB-DLA
fall into two categories: power status (1 LED) and network status (2 LEDs).
5.3.1. LED Colors and Blink codes
POWER ON (red) - The LED is off when no power applied. After the LED self-
test, the LED goes on steady.
J1708 (green) - The LED flashes on when the DLA detects traffic on the J1708
input terminals or when a J1708 message is sent from the DLA. During heavy
traffic, the LED may appear to be on steady. The LED stays off if no traffic is
detected and no messages are sent.
J1939/CAN (red) - The LED flashes on when the DLA detects traffic on the
J1939/CAN input terminals or when a J1939/CAN message is sent from the DLA.
During heavy traffic, the LED may appear to be on steady. The LED stays off if no
traffic detected and no messages are sent.

Software Tools for the USB-DLA
6. SoftwareTools for the USB-DLA
The following software tools are used to support the DLA on a PC.
USB update tool can be used to update the embedded firmware in the DLA.
VAPIserver starts automatically when an RP1210 application is started and
provides a link between the USB or serial hardware and the PC application.
RP1210 Chooser allows the use of different DLA hardware (such as Vansco's
serial or parallel DLA) on the same computer.
Parker Vansco also has a number of software tools that are useful for troubleshooting
vehicle networks. These are applications that have been developed over the years to
assist in developing products such as instrument clusters, transmission controllers
and DLAs.
CANsniff is a PC application that displays the amount of data on the CANbus as
well as actual traffic.
SimEngine is a powerful PC application that can simulate engine controller
messages.
SimGauges creates a virtual J1939 instrument cluster on a PC for a graphical
display of data received by the DLA.
iINFORMATION
These softwares started as engineering tools and, as a result, are not full-featured,
professional software tools.
For further information about these software tools, please contact your Parker
Vansco representative.
6.1. USB Update Tool
NOTICE
USB update tool is a program for updating the embedded firmware in the USB-DLA.
If this is done incorrectly or the wrong firmware is loaded, the DLA can be rendered
inoperative. The unit must then be returned to Parker Vansco for reprogramming.
This tool is used to update the embedded firmware on the DLA itself.
Plug the DLA into the USB port and run the program udutool.exe. The program
should show you that the DLA is connected to the USB port. Click on the DLA to
select it for a firmware update.
Use the browse button (indicated by the ellipsis) to select an appropriate firmware
file. A valid DLA firmware file can be identified by three characteristics:

USB Data Link Adapter 18
Software Tools for the USB-DLA
1. The filename should start with the DLA product number 779.
Never program the DLA with firmware file that does not start with 779.
2. The filename should end with the application version number.
Never program the DLA with an application code that has a lower version
number.
3. The file type should be .VSF.
The software will display an alert asking you if you are sure you want to reprogram
the DLA. Click Yes to continue. A progress bar will move across the screen. A dialog
box will inform the user if the update was successful.
Figure 11: Updating the DLA firmware with udutool
USB update tool will only allow you to update only the application code in the DLA
and not the bootcode. This means that if you interrupt the update, you should be
able to run it again and complete the update. However, it is highly recommended
that the update be run without interruptions. The DLA should only be disconnected
when USB update tool reports the update has completed successfully.

USB Data Link Adapter 19
Software Tools for the USB-DLA
6.2. VAPI Server
A new icon appears in your system tray when you start an RP1210 application that
uses the USB-DLA. This is the VAPIserver (Vansco Application Program Interface
Server) program; it provides the interface between the applications (such as
SimGauges, SimEngine and CANsniff) and the DLA hardware.
Figure 12: VAPI Server icon
Double clicking the VAPIserver icon will bring up a window showing the status of the
VAPIserver program. The VAPIserver will search for a DLA connected to the PC once
every minute. If it finds one, the status will change to "Connected" and the
VAPIserver will use that DLA until the connection is lost. The status window shows
the number of applications that are connected to the DLA.
Figure 13: VAPI Server status window
The status window displays information on the data being sent through the DLA.
This includes counts of the bytes sent through J1939 and J1708 and also connection
status. In general, the Adapter Packets Tx count should match the Vapi Server
Packets Rx count. However, if the DLA is disconnected, the Adapter Packets TX
count will continue to increase as the PC attempts to communicate with the DLA.
