Installation
USB 3072/ basicLIN 3072 – User Manual 1-1
1Installation
1.1 Hardware Installation
Generally hardware installation for USB 3072/ basicLIN 3072 means
exchanging the transceiver modules.
Please make absolutely certain that all of the installation procedures
described below are carried out with your system switched off.
If it is necessary to exchange transceiver modules, the corresponding
device is to be opened according to its conditions.
Doing this, pay attention to the general rules to avoid electrostatic
charging. Transceiver modules must never be removed or mounted
with the power switched on! In addition, the right alignment is
absolutely required (see Assembly).

Installation
1-2 USB 3072/ basicLIN 3072 – User Manual
1.2 Driver Installation
For proper installation of the GOEPEL electronic USB drivers on your
system, we recommend to execute the GUSB driver setup.
To do that, start the
GUSB-Setup-*.exe setup program (of the
supplied CD, “*” stands for the version number) and follow the
instructions.
At present, the available device driver only supports Windows®
2000/ XP systems.
If you want to create your own software for the boards, you possibly
need additional files for user specific programming (
*.LLB , *.H ).
These files are not automatically copied to the computer and have to
be transferred individually from the supplied CD to your development
directory.
The USB interface uses the high-speed data rate according to the USB2.0 specification (if possible, otherwise full-speed).
After driver installation, you can check whether the modules are
properly embedded by the system.
The following picture shows the successful embedding of one
USB 3072/ basicLIN 3072 device with three controllers:
Please note that the Device Manager shows ALL USB controllers.

2.1 Definition
USB 3072 LIN boards are GOEPEL electronic GmbH communication
boards with USB 2.0 interface.
These boards are used in general control technology, e.g. for
applications in automotive technology.
Please note: Downloading the Xilinx FPGA is absolutely required for operating the USB 3072 board (see Xilinx_Download in the
Windows Device Driver section).
For operating USB 3072 you need the GOEPEL electronic USB rack
which can cover up to 16 GOEPEL electronic USB boards.
In this case, power supply comes from the built-in power supply
unit.

2-2 USB 3072/ basicLIN 3072 – User Manual
basicLIN 3072 is a GOEPEL electronic GmbH stand-alone device based
on a USB 3072 communication board to be connected to a PC or
laptop. It was in particular developed for applications out of complex
test systems.
The external power supply allows the use of this device for data
acquisition and the inspection of signals in motor vehicles.
Power supply with 8..25 VDC (and approx. 500 mA at 12 V) is effected
via the two ext. Power Supply females (red = plus/ blue= minus) at
the device’s rear side (opposite to the LIN interfaces connector).
These females are used to supply the internal logic. In addition, the
blue female is connected with the GND connections of the USB and
LIN interfaces.

Resources of USB 3072/ basicLIN 3072:
♦3 LIN interfaces of Version 2.0b
♦As an option, every interface can also be designed as a K-Line
interface
♦Extended trigger functions with one trigger input and output
per interface to the frontal plug connector or the backplane
♦For each LIN interface USB 3072/ basicLIN 3072 has an own 32
bit microcontroller (TriCore TC1765, 40MHz)
♦Visualisation of the controller states by LEDs arranged at the
front panel (two LEDs per controller, see LED Indication)
♦High flexibility through pluggable transceiver modules
In this User Manual, Controller means ALWAYS one of the microcontrollers assigned to each LIN interface
(with the exception of the “LIN Controller” designation on the front
panel of a USB 3072 board, which refers to the entire board).
In case a basicLIN 3072 device does not provide enough resources for
your applications, there is a GOEPEL electronic USB Rack available to
cover up to 16 GOEPEL electronic USB boards.
Then the power supply comes from a built-in power supply unit with
230V or 115V connector at the rack’s rear side.

Please use the delivered USB cables to connect USB 3072/
basicLIN 3072 devices to the PC’s USB interface.
Other cables may be inapplicable.
Addressing an individual USB 3072/ basicLIN 3072 device when
operating several USB 3072/ basicLIN 3072 at the same computer takes
place exclusively according to the serial numbers of their LIN
controllers (see Control Software): The LIN controller with the
LEAST serial number is always the device with the number 1.
To improve clarity, we recommend to arrange the individual
USB 3072 devices in the USB rack in the order of ascending serial
numbers of their LIN controllers (or to connect the individual
basicLIN 3072 devices in the same order to the computer)

2.3.3 Commu-
nication Interfaces

Hardware
USB 3072/ basicLIN 3072 – User Manual 2-7
LIN:
The transceivers are designed as plug-in modules. Generally, the
TJA1020 is used for this type of transceicer.
For the standard design of the transceiver modules, it is possible to
change over between Master and Slave configuration per software
using the relays Rel9 for LIN1, Rel10 for LIN2 or Rel11 for LIN3.
The pull-up resistors for LIN are located on the transceiver modules.
Via the VBat contacts the power supply of the transceiver modules is
connected. According to the LIN specification, this power supply is to
be carried out via a reverse-connect protection diode and a support
capacitor (so the VBat voltage is fed by VBAT in 1..VBAT in 3).
The voltage fed at the power supply (voltage) pin should not exceed
the transceiver’s scope (for example, the upper VBAT voltage limit is
27 V for TJA1020).
The VBAT out 1..VBAT out 3 connections are monitoring outputs to
measure the real voltage at the transceiver, possibly to compare this
voltage with the LIN signal level.
For special control and measuring tasks, the communication boards
are provided with a hardware trigger output and input for each LIN
interface.
Their function description can be taken from the LIN Commands
section of the GOEPEL Firmware documentation.
In addition, USB 3072 boards offer the possibility to separate the LIN
communication bus from the corresponding test object (device or unit
under test) via the relays 1..3.
The relays 4..6 allow the interconnection of the three LIN interfaces to
a common bus on the board (see Figure 2-4).
K-Line:
The transceivers are designed as plug-in modules. Generally, the
L9637 of ST is used for this type of transceicer.
Via the VBAT in1..VBAT in3 contacts, the supply voltage of the
transceiver modules is connected. The voltage fed at the power supply
(voltage) pin should not exceed the transceiver’s scope (for example
for L9637, the upper VBAT voltage limit is 36 V).
To bridge the reverse polarity diode for VBat for LIN, the VBAT voltage
can be fed via VBAT out 1..VBAT out 3.

2.4 Delivery Notes
USB 3072/ basicLIN 3072 devices are delivered as follows:
♦3x LIN interface
As an option, each interface can also be designed as a K-Line
interface.
In addition to the interface, the type of the corresponding LIN/ K-Line
Transceiver as well as the required Functionalities for each interface
must be selected.
For operating USB 3072 boards you need the GOEPEL electronic USB
rack which can cover up to 16 GOEPEL electronic USB boards.
In this case, power supply comes from the built-in power supply
unit.

Control Software
USB 3072/ basicLIN 3072 – User Manual 3-1
3Control Software
There are three ways to integrate USB 3072/ basicLIN 3072 hardware in
your own applications:
♦Programming via G-API
♦Programming via DLL Functions
♦Programming with LabVIEW
3.1 Programming via G-API
The G_API (GOEPEL-API) is the favored user interface for this
GOEPEL hardware.
You can find all necessary information in the
G-API folder of the
delivered CD.
3.2 Programming via DLL
Functions
Programming via DLL Functions is possible also in future for existing projects which can not be processed with the GOEPEL electronic
programming interface G-API.
We would be pleased to send the GOEPEL Firmware documentation to
you on your request. Please get in touch with our sales department in
case you need that.
The GUSB_Platform expression used in the following function description stands for the name of a GOEPEL electronic USB driver.
For the used structures, data types and error codes refer to the
headers – you find the corresponding files on the supplied CD.
In this User Manual, Controller means always the microcontroller assigned to the corresponding LIN/ K-Line interface of a USB 3072/
basicLIN 3072 device. An own USB Controller providing the USB 2.0
interface is assigned to each of these Controllers.
On the other hand, USB Controller means ALWAYS the controller
providing the USB 2.0 interface of the USB 3072/ basicLIN 3072 device.
