5 The PCIcanx Hardware
For quick and easy installation, all Kvaser PCIcanx boards are plug-and-play boards.
5.1 PCI-X and PCI slots
The universal design of the Kvaser PCIcanx boards makes them suitable for both PCI-X and
PCI slots. Although, the board works in PCI-X as well as PCI slots, it is not a PCI-X product.
Hence, it operates in PCI mode in all slots. Major features of the Kvaser PCIcanx board:
Legacy compliant with PCI Local Bus Specification v2.3
Support for PCI-X Specification v 1.0 and higher versions
Universal 3.3 V and 5 V keyed board connector
Supports 3.3 V and 5 V supply voltage
Operates at a bus frequency of 33 MHz
Figure 2. The 3.3 Volt and 5 Volt keyed board connector.
Here is a list of supported PCI-X and PCI slots:
3.3 V, 64 bit
3.3 V, 32 bit
5 V, 64 bit
5 V, 32 bit.
To summarize, the Kvaser PCIcanx boards can be used in any PCI-X and PCI slots. Just
keep in mind - all cards on a common bus can only run as fast as the slowest card. For
example if there is a 33 MHz card in slot 1 and a 66 MHz card in slot 2, both cards will run at
33 MHz. The performance degradation can be avoided by separating the Kvaser PCIcanx
board (33 MHz / 32-Bit) and other PCI and PCI-X devices using different bus segments.
Note –not all motherboard vendors comply with the industry standards for PCI-X and PCI
slots. Kvaser AB cannot assume any responsibility for that.
5.2 The Isolated CAN Driver
Kvaser’s PCIcanx cards for CAN systems feature up to four CAN controllers. Each CAN-
driver SN65HVD251 is isolated both from the CAN controller and all other CAN drivers. The
CAN driver will get the necessary power from the PCI bus via an isolated DC/DC convert. The
isolation between the CAN-controller and the CAN-driver has a delay of maximum 50 ns in

Kvaser PCIcanx User's Guide 10(20)
Kvaser AB, Mölndal, Sweden —www.kvaser.com
each direction. This will reduce the possible cable length with 20 meter compared to having
no isolation.
Due to human safety, the voltage should never at any part of the PCIcanx board be more than
+/- 50 Volt from the PC-computer chassis ground. Note that the PCIcanx will not secure this
condition itself. If any DSUB pin has an external voltage in the range below +/-500 Volt from
chassis ground this will also be the true voltage at this pin.
Each CAN-driver circuit is protected from short time over voltage like ESD and accidental
short cuts to high voltage. An over voltage beyond +/-500 Volt, on any used DSUB pin, will
cause a rapid shortcut to ground. If the applied over voltage do have a high energy source
some PCB wires may burn away in that case.
5.3 CAN Bus Termination
There are no terminating resistors onboard the standard PCIcanx board. However, there is
room available to mount terminating resistors onboard all product versions. These terminating
resistors can also serve as a load between the CAN bus wires; this is needed for the ISO
11898-2 compliant bus drivers to work properly. Please contact our Support Team for detailed
instructions.

5.4 D-SUB connector
The D-SUB connector(s) are mounted on a bracket and connects to the metallic housing of
the PC. The pinning of the 25-pin DSUB connector is listed in table 4.1, and the pinning of the
9-pin DSUB connector is listed in table 4.2

5.5 The LED indicators
The PCIcanx HS and PCIcan HS/HS boards have LED indicators, one per channel. They are
visible through a hole in the mounting bracket. The LEDs indicates CAN bus activity and will
emit a short pulse whenever a CAN message is received or transmitted.

6 Software Development Information
This section is intended for those who want to program the PCIcanx card directly. Normally,
you would choose to use the supporting device drivers available for the PCIcanx card. Refer
to the “CANLIB Software Development Kit” documentation for further information on these
device drivers from a programmer’s point of view. Please note that this board is fully software
compatible with the Kvaser PCIcan boards.
6.1 Additional Documentation
This document includes all information you need to use the circuits on the card. However, the
circuits themselves are not described here so information about these must be obtained from
the suppliers. See the list of references on page 15. General knowledge about the PCI bus is
also assumed.
6.2 A note on the different PCIcanx versions
PCIcanx 4xHS has four CAN controllers. PCIcanx HS/HS has two CAN controllers and
PCIcanx HS has one controller. This chapter describes primarily PCIcanx 4xHS; if you have
one of the other cards, just disregard the circuits and switches that are not on your card.
Differences between the different members of the PCIcan family are explicitly noted wherever
they occur.
6.3 The PCI bus controller
All PCIcanx boards use the same PCI controller, which is a Xilinx FPGA with PCI core. The
PCI controller is responsible for address decoding and interrupt steering.
The initialization of the PCI controller is outside the scope of this manual. Typically, it is
carried out by the operating system and/or the BIOS. There are a few registers you have to
set up in the driver; these are described below.
6.4 Address decoding
The PCI controller can decode up to 5 different address areas, three of which are used by the
PCIcanx.

Xilinx registers
Address area number 1, the one used for the SJA1000’s, is further subdivided into four areas
of 32 bytes each; one for each (possible) SJA1000.
There is no actual AMCC S5920 in the PCIcanx, but the first address area is set up to be
compatible with the Kvaser PCIcan cards.

Kvaser PCIcanx User's Guide 14(20)
Kvaser AB, Mölndal, Sweden —www.kvaser.com
6.5 Interrupts
The PCIcanx uses one PCI bus interrupt, INTA#. It is asserted whenever one or more
SJA1000’s have their interrupts active. To reset an active interrupt, read the interrupt status
register in all present SJA1000s –the interrupt of the corresponding SJA1000 will then
automatically clear.
To check the status of the interrupt line, test the INTERRUPT ASSERTED bit (number 23) in
the INTCSR register in the “S5920”.
To enable or disable interrupts from the PCIcanx, use the ADD-ON INTERRUPT PIN
ENABLE (bit 13) in the INTCSR register in the “S5920”.
6.6 Registers in the Xilinx
The Xilinx FPGA implements a few registers.

VERINT
Bit 7 - 4 contains the revision number of the
FPGA configuration. 15 is the first revision, 14 is
the next, and so on.
The current FPGA revision number is 13 (which is read from the VERINT register as
1110xxxx). Future revisions (12, 11, 10, …) will remain compatible with revision 13.
6.7 PCI Configuration Data
The following data are configured automatically into the Xilinx FPGA PCI controller when
power is applied to the card.

6.8 Configuration of the SJA1000
Refer to the SJA1000 data sheet for all details on how to program the SJA1000. You need to
know the following:
RX1 is connected to ground.
TX1 is not connected.
CLKO is not connected.
Setting the OCR register to 0xDA is a good idea. This means “normal output mode”,
push-pull and the correct polarity.
In the CDR register, you should set CBP to 1. You will probably also want to set the
clock divider value to 0 (meaning divide-by-2), the Pelican bit, and the clock-off bit
(you have no need for CLKOUT anyway.)
The only way to find out how many SJA1000 a PCIcanx card has, is to try to access them one
after the other.
