1Board Installation
1.1 Hardware Installation
Please make absolutely certain that all of the installation procedures
described below are carried out with your system switched off and
disconnected from the mains supply.
Please refer also to the user manual of your PXI/ PCI system for
additional installation instructions that possibly have to be followed.
Electro Static Discharge (ESD) can harm your system and destroy
electronic components. This can lead to irreparable damage on both
the PXI/ PCI 3080 controller board and the system hosting the board
as well as to unexpected malfunction of your test system.
Therefore do not touch the board surface or any connector pins and
electronic components.
The PCI™, CompactPCI™ or PXI™ system is to be opened according
to its conditions. A free slot is to be selected in your system.
Now, the slot cover is to be taken away from the slot selected.
To do this, unscrew the fixation screws if necessary and remove the
cover from the slot.
(If it is necessary to exchange transceiver modules, pay attention to
the general rules to avoid electrostatic charging, see the warning
above. Transceiver modules must never be removed or mounted with
the power switched on!
Additionally, the right alignment is absolutely required.)
Insert the board carefully into the prepared slot. For PXI boards, use
the lever at the front plate in order to push in the board finally.
When the board has been inserted properly, it is to be fixed by means
of the screws at the front plate.
Now, the board has been installed correctly.
Afterwards, carry out the operations required at the system to make it
ready for operation anew.

1.2 Driver Installation
PXI/ PCI 3080 controller boards can be operated under Windows®
2000/ XP as well as under Windows®7/ 64 bit.
Due to the plug and play capability of Windows®, for every newly
recognized hardware component a driver installation is started
automatically via the hardware assistant.
The hardware assistant can carry out the installation of the device
driver by using the
inf file contained in the GPxi3080 folder of the
supplied CD.
If necessary, you can find the required
inf files as follows:
♦ GPxi3080.inf for Windows®2000/ XP in the
Win2000 (Version xx) folder
♦ GPxi3080_x64.inf for Windows®7/ 64 Bit in the
Win7_x64 (Version xx) folder
It is not absolutely essential to restart the system.
The following step is only required in case you do not use the G-API
(see also Control Software).
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.

2.2 Technical Data
The PXI 3080 communication board is a plug-in board developed for
the PXI™ bus (PCI eXtensions for Instrumentation). Basis of this bus
is the CompactPCI™ bus.
The board can be plugged into any desired slot of a CompactPCI™ or
PXI™ system (except for slot 1). It can be definitely identified also in
the case that several boards of this type are used in the same rack.
The PCI 3080 communication board is a PC plug-in board for the PCI
Local Bus Rev. 2.2.
It can be operated at any PCI slot (32 bits, 33 MHz, 3.3 V)
Both boards do not have jumpers for hardware detection and are
automatically integrated into the respective system.
The dimensions of both boards correspond to standard dimensions of
the accompanying bus system:

2.3 Construction
An ASIC is used as the interface to the PCI or cPCI bus on the PXI/
PCI 3080 boards. It includes all the function blocks required for the
communication with the computer bus.
The PCI 3080 communication board does not have a PXI interface.
To exchange trigger signals with other GOEPEL electronic PCI boards
despite of that, an additional plug connector is on this board with two
lines configurable as input or output (J902 in Figure 2-7).

2.3.1 General

Hardware
PXI 3080/ PCI 3080 – User Manual 2-5
PXI 3080: PXI racks do have an own geographical slot addressing of
the backplane. Numbering starts with 1and can be seen at the
cover’s front side. Mount always an embedded controller or an MXI
card at slot 1.
The PXI 3080 board can read out this geographical slot address. For
that the belonging FPGA file has to be loaded to the XILINX (see the
XilinxDownload functions for different drivers in the Control Software
section).
PCI 3080: PCI racks do not have an own geographical slot
addressing. There is a separate DIP switch (S900 in Figure 2-7) for
clear identification of the board in a system with several PCI 3080
boards. You can select up to 16 addressing variants by this. The
corresponding binary value (0to 15) set with the S900 switch can be
read out by the delivered software.
2.3.2 Addressing

Hardware
2-6 PXI 3080/ PCI 3080 – User Manual
2 x CAN Interface Version 2.0b:
The type of the mounted transceiver is decisive for proper operation
of a CAN interface in a network. Often CAN networks do only operate
properly in the case that all members use a compatible type of
transceiver.
To offer maximal flexibility to the users of the PXI/ PCI 3080 boards,
the transceivers are designed as plug-in modules. There are several
types (high speed, low speed, single-wire etc.) that can be easily
exchanged.
Not only the type of the mounted transceiver, but also the terminating
resistor of the bus is very important for proper operation of a CAN
network.
For the use of highspeed CAN transceivers, usually one 120 Ohm
resistor is active on each CAN interface.These resistors can be
deactivated by removing the J1401 or J1501 jumpers.
In the case of lowspeed CAN transceivers, usually two resistors with a
resistance value of 10 kOhm for RTH and RTL are active for each
CAN interface (by inserting the J1402/ J1403 or J1502/ J1503
jumpers). Then the J1401 or J1501 jumpers must NOT be
plugged-in.

PXI 3080/ PCI 3080 – User Manual 2-7
2 x K-Line Interface (ISO 9141) or
2 x LIN Interface Version 2.0:
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 contacts the power supply of the transceiver modules is
connected. To bridge the reverse-connect protection diode for VBatfor
LIN, the J1602 or J1703 jumpers must be plugged-in.
In the case the pull-up resistor to VBat is to be activated, the J1601
or J1701 jumpers must be plugged-in.
LIN:
The transceivers are designed as plug-in modules. Generally, the
TJA1020 of Philips 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 Rel1 relay for LIN1 and Rel2 for LIN2. The pull-up resistors
for LIN are located on the transceiver module. Therefore the J1601
or J1701 jumpers must NOT be plugged-in.
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. Therefore the
J1602 or J1703 must NOT be plugged-in.

LIN/ K-Line Interface

Hardware
2-8 PXI 3080/ PCI 3080 – User Manual
J1850 Interfaces:
The transceivers are designed as plug-in modules.
Generally, the AU5780 of Philips is used for J1850 VPW
transceivers.
The output circuitry of a J1850 PWM transceiver is realized by discrete
components.
The transceiver for a J1850 VPW interface has to be inserted at the
position for J1850 transceivers.
On the other hand, the transceiver for a J1850 PWM interface must be
inserted at the position for a K-Line/ LIN 2 transceiver
(see Figure 2-6 and Figure 2-7).
J1701 must NOT be mounted in the case of a J1850 PWM
interface!
