2Installation
2.1 Software installation
A driver is required in order to operate the interface.
For the installation of the CAN driver VCI, please read the VCI installation hand-
book.
2.2 Hardware-Installation
Before you plug the PC-I 04/PCI into the PCI slot, you should install the software
driver (see section 2.1).
For all work on the PC and interface, you must be statically discharged. Work
must be carried out on an earthed, anti-static work mat.
Take the following steps in sequence:
(1) Switch the PC off and disconnect the mains plug.
(2) Open the PC according to the instructions of the PC manufacturer and find a
suitable place to plug in.
The interface is designed according to the PC-standard and can easily be
built into the computer. Do not use force when plugging in.
(3) Make sure the interface sits tightly in the PC.
(4) Close the PC; the hardware installation is now complete.

3.1.1 Power supply via CAN-plugs
With the solder jumpers JP4, JP5, JP33 and JP36, VCC (5 V) or GND can be con-
nected to the CAN-plugs of the two CAN-lines. For this, the jumpers given in the
following table are to be connected. The solder jumpers are on the solder side of
the PC-I04/PCI.

Attention: This voltage may be loaded with maximum 100 mA.
With galvanically isolated bus connections, the signals GND and VCC are also
galvanically isolated from the power supply of the PC.
3.1.2 Connection to ground for measuring purposes
There is a connection on the PC-I 04/PCI for a ground pin. The abbreviation GND
is marked on the board next to the drill hole.

3.2 Design of the CAN-plugs
Two isolated high-speed bus attachments according to ISO 11898-2 can be
mounted on the interface.
The signals of the first bus connection are connected to the 9-pin Sub-D-plug X1.
If the second bus connection is printed, the signals for the CAN-bus of the se-
cond bus connection are connected to the header X2.

3.3 Bus terminator
On the PC-I04/PCI there are bus terminator resistors for the two bus con-
nections. The bus terminator for the first bus connection is connected via
the solder jumper JP6 and for the second bus connection with JP7. Bus
termination is with a 120 Ohm resistor between CAN Low and CAN High.
On delivery, the bus connections are not active.
Alternatively bus termination can also be made externally with the IXXAT
accessory “SubD9 connector with CAN bus terminator resistor“ (order
number 1.04.0075.03000).

4.1.1 Access to CAN-controllers
There can be up to two CAN-controllers of the type Philips SJA1000 on the inter-
face.
The first CAN-controller is displayed in the range from 0000h to 00FFh, the se-
cond CAN-controller in the range of 0200h to 02FFh from the basic address of
the card. When accessing the corresponding memory range, the CAN-controller is
selected automatically. The basic address is allocated by the PCI plug-and-play
BIOS.
The exact register description of the SJA1000 can be found in the corresponding
Philips data sheets (web-addresses in Appendix ).
The Output Control Register of the CAN-controllers must be loaded with the val-
ue DEh or 5Eh.

4.1.2 Resetting the CAN-controllers from the PC
By writing a random value to an address of the reset range (0100h to 01FFh for
the first CAN-controller and 0300h to 03FFh for the second CAN-controller), a
hardware reset is carried out on the corresponding CAN-controller.
4.2 Triggering an interrupt on the PC
The CAN-controllers can trigger an interrupt on the PC. Both CAN-controllers
share one interrupt (INTA# of the PCI-interface).
The PCI plug-and-play BIOS allocates an interrupt to the card (IRQ3..IRQ15).
4.3 Interrupt handling
The card is transparent, which means that the interrupt signal on the PCI-bus
(INTA#) is active when a CAN-controller issues an interrupt signal and it remains
active until the signal on the CAN-controller is reset by an interrupt acknowledge
by the PC. The PCI-bus interface chip PLX PCI9050-1 does not appear here.
It should be noted that the PCI-bus interrupt in the PCI-specification is defined as
level-triggered.
