2Commissioning
2.1 System Requirements
Your system must comply with the following requirements:
•At least 4-times PCIe slot
•At least Dual Core CPU
•Windows 7 or later
2.2 Hardware Installation
Please make sure that all hardware installation work is done while the system is off! The power
supply should be disconnected.
After you have completely unpacked the G PCIe 6281 Multibus Controller, please check the tight fit of the
transceiver boards.
Electrostatic discharge (ESD) can damage your system and destroy electronic components. This can
lead to irreparable damage to the PCIe board or to the system in which the board is operated. The
result is unexpected malfunctions of your test system. Never touch the board surface, connector ter-
minals or electronic components.
Please also use the manual for your PCIe system. If necessary, further installation instructions to be
observed are included.
Open your PCIe™ system according to its circumstances. Select a free slot in your PCIe™ system. Remove the
existing slot plate of the selected slot. For this, the fastening screws must be loosened.
The board should be inserted carefully in the prepared slot. After contacting the board, it is fastened to the front
panel with the screw. Thus, the board is installed properly. Afterwards, if necessary, the work on the system must
be carried out to make it ready for operation again.
Finally, connect the communication interfaces of the G PCIe 6281 Multibus Controller with the devices that you
want to test (DUT).
2.3 Driver Installation
The G PCIe 6281 Multibus Controller can be operated under Windows 7, 8 and 10 as well as under Linux.
2.3.1 Windows Device Driver
PCIe devices can run on Windows 7, 8 and 10. The plug-and-play capability of Windows automatically launches
a driver installation for each newly detected hardware component through the Hardware Wizard. With the exe
file included on the enclosed CD, the Hardware Wizard can install the device driver. A restart of the system is not
mandatory.
2.3.2 G-API
The G-API (Goepel electronics Application Programming Interface) is a software interface. It supports various
hardware products from GOEPELelectronics and gives the user the opportunity to integrate them into their

2Commissioning
GPCIe6281 5
own applications. The enclosed CD contains the setup for installing the G-API , which will guide you through the
Hardware Wizard. For more information about G-API , its installation and about the HardwareExplorer , see the
G-API Quickstart Guide .
2.4 Network Configuration
When using the ethernet interface, no driver installation is required to communicate with the control computer.
The device can be addressed directly via the IP address. However, to address the device, you will need a network
adapter that has a valid IP address and subnet mask. Otherwise the PC / Laptop will not be able to communicate
with the G PCIe 6281 Multibus Controller in the network.
For this setup, open the "Properties" dialog of the corresponding network adapter and select "Internet Protocol
Version 4 (TCP / IPv4)".
Figure 2.1Properties of the network adapter
Put a tick next to "Use the following IP address" and set the IP address and subnet mask according to the follow-
ing rules:
•The IP-Address of the G PCIe 6281 Multibus Controller must be different from that of the network
adapter.
•The subnet mask must be set to a value such that both IP addresses ( G PCIe 6281 Multibus Controller
and network adapter) are located in the same subnet.
Example:
The default IP address of the G PCIe 6281 Multibus Controllers is 192.168.1.62 (Port 5134). For exam-
ple, if you set your network device to IP address 192.168.1.1 and the subnet mask to 255.255.255.0,
then both devices are now on the same subnet 192.168.1.xyz.

2Commissioning
GPCIe6281 6
Figure 2.2Example IP address of the network adapter
After the network adapter has been set up correctly, the G PCIe 6281 Multibus Controller can be addressed di-
rectly after its hardware installation via its IP address. The IP address of the G PCIe 6281 Multibus Controllers
can be changed by means of the HardwareExplorers , whereby the entered IP address only becomes effective af-
ter a successful restart.
Figure 2.3HardwareExplorer with G PCIe 6281 Multibus Controller
A second way to change the IP address is to use the G-API command
G_Common_Ethernet_IpAddress_Set. The new IP address is effective after a restart.
It is necessary to change the static IP address if you want to operate several Series 62 Multibus Con-
trollers or other GOEPELelectronics devices (such as basicCAN 61xx ) in the same network. In this
case, always connect only the device whose IP address is to be changed and change it. Make a note of
the new IP addresses and the associated serial numbers if you need this information again later. If all
devices have different IP addresses, they can be operated together on the same network.

2.5 Firmware Update
Please make sure to use the correct firmware variant when updating the firmware. The installation of
the wrong firmware variant could lead to a loss of functionality and thus cause malfunctions of your
application. (In such a case, reinstalling the correct firmware variant can restore the functionality.)
To update the firmware, do the following:
•Download the latest firmware update file from genesis.goepel.com
•Open the GOEPELelectronics HardwareExplorer
•Right-click on the selected device (for example "PCIe6281") and select "Flash Firmware"
•Select the appropriate update file in the selection window and confirm with "OK"
•Confirm after successful flashing with "OK"
2.6 Change of the Transceiver
If it is necessary to replace a transceiver, observe the general rules for avoiding electrostatic charge.
A correctly positioned plugging in the transceiver must be realized.
Please make sure that alle hardware installation work is done while the system is off! The power
supply should be disconnected.
To change your transceiver, follow these steps:
•Loosen the screw on the front panel and carefully pull the board out of the slot.
•Then pull the appropriate transceiver from the main board upwards without tilting it.
•Plug the new transceiver into the connector on the main board. When plugging in the transceivers,
please pay attention to their position and orientation. The Automotive Ethernet transceivers can only
be plugged into the slots TRX7 and TRX8. There are two connectors per slot required for communica-
tion with the Automotive Ethernet transceivers.
•Carefully insert the board into the slot again and secure it with the screw on the front panel.

3.4 Design and Function
The G PCIe 6281 Controller has been developed as a highly flexible multibus controller platform. It offers up to
eight serial bus interfaces and another eight digital I/O interfaces. The bus interfaces can be configured in nu-
merous variants. Each bus interface has a transceiver slot assigned to it, with the respectively inserted transceiv-
er determining the type of interface of the associated node. If e.g. a CAN transceiver is plugged into slot TXR2, this
node forms the interface CAN2 (ID 2). If instead a LIN transceiver inserts, this node forms the interface LIN2 (ID
10). The software addresses the interfaces according to the ID (ID 2 and ID 10 in this example).
The G PCIe 6281 Multibus Controller offers four digital inputs and four digital outputs. Two of these can be re-
configured to SENT Rx or SENT Tx.
There are four RJ.5 connectors on the front of the controller board, through which the connections of all bus in-
terfaces and digital inputs / outputs are routed. In addition, you will find four status LEDs that indicate the oper-
ating status of the controller board.
Below the RJ.5 connector is the socket for the 1GBit Ethernet interface. It is either used to control the controller
or can serve as a debug interface as well as to transfer large amounts of data (e.g., monitor data).

3.4.5 Power Supply
The PCIe board of the G PCIe 6281 Multibus Controllers is supplied via the PCIe interface.
3.4.6 Galvanic Isolation
Overvoltages can damage expensive test equipment or lead to unsafe test results. The potential separation pro-
tects against overvoltages and can suppress dangerous surges. It also prevents ground loops responsible for da-
ta errors due to ground potential differences.
On the G PCIe 6281 Multibus Controller, the host system is electrically isolated from the interfaces leading to the
RJ.5 connectors. This includes the CAN/ CANFD, LIN/ K-Line, Automotive Ethernet and FlexRay communication
interfaces as well as the digital inputs and outputs.
3.4.7 SYNC
There are two SYNC (Synchronization) connectors on the back of the PCIe board of the G PCIe 6281 Multibus
Controller. These can be used to connect multiple PCIe boards so that the cards can synchronize with each oth-
er. "SYNC left" (see Overview of GPCIe6281 Multibus Controller) will be connected with the left placed card and
"SYNC right" with the right placed card. This means that the "SYNC left" connector of one PCIe board is connect-
ed to "SYNC right" of the other board.
The SYNC connectors are not to be used for any purpose other than the above purpose. The pin as-
signment will therefore only be issued on request.

3.5 Onboard Interfaces
The G PCIe 6281 Multibus Controller offers the possibility to use a total of eight Automotive Bus interfaces. For
each bus (CAN/ CANFD, LIN/ K-Line, FlexRay and Automotive Ethernet), transceivers are available that can be
replaced with little effort in accordance with the test requirement (see Change of the Transceiver). It also sup-
ports up to eight conventional signals (digital in/ out and SENT), four as input and four as output. Each transceiv-
er type is coded and uniquely identifiable. Detailed information about the interfaces and how they are supported
can be found on the following pages in the corresponding chapters.
The interfaces are generally supplied with an internal 12V voltage (VBATint). The supply can also be done exter-
nally (further details for the different interfaces can be found in the respective section). Please note that the ex-
ternal power supply always affects the two transceivers connected to one RJ.5 connector:
VBAText Transceiver
VBAText0 TRX1/2
VBAText1 TRX3/4
VBAText2 TRX5/6
VBAText3 TRX7/8
Table 3.8Assignment of transceivers to VBAText
Due to the large number of possible variants, how the various bus interfaces can be connected to the transceiv-
er slots some variants were defined in order to be able to handle these on the firmware side. The G PCIe 6281
Multibus Controller can be equipped with these variants. On the software side the transceiver slots all have a
unique assignment via which the interfaces are addressed. The interface options supported by the firmware vari-
ants can be found in the following table:
