Overview
1. Overview
1.1 Description of the Module
Figure 1: Block circuit dia ram of CAN-PCI/200
The CAN-PCI/200 is a PC board desi ned for the PCI bus. It is available with one or optional two
CAN interfaces.
The ISO 11898 compliant CAN interfaces allow a data transfer rate of 1 Mbit/s. Amon many other
features, the bit rate can be set by software. The CAN interface is electrically isolated from the
other potentials by optocouplers and DC/DC-converters.

Hardware Installation
2. Hardware Installation
Read the safet instructions at the beginning of this document carefull ,
before ou start with the hardware installation!
Danger!
Electric shock risk. Never carry out work while power supply volta e is switched on!
Attention !
Electrostatic dischar es may cause dama e to electronic components. To avoid
this, please dischar e the static electricity from your body by touchin the metal
case of the PC before you touch the CAN-PCI/200.
Procedure:
1. Switch off your computer and all connected peripheral devices (monitor, printer, etc.). Switch
off the connected CAN devices.
2. Dischar e your body as described above.
3. Disconnect the power supply of the PC from the mains.
If the computer does not have a flexible mains cable, but is directly connected to mains,
disconnect the power supply via the safety fuse and make sure that the fuse cannot switch
on a ain unintentionally (i.e. with caution label).
Danger!
Never carry out work while power supply volta e is switched on!
4. Open the case.
5. Select an open PCI slot and remove the slot cover at the back of the PC. Unfasten the screw
which fixes the slot cover and retain it for fixin the module afterwards.
The CAN module can be inserted into every PCI slot.
6. Insert the CAN-PCI/200 board into the selected PCI slot. Carefully push the board down until
it snaps into place.
7. Attach the board.
Use the screw you removed from the slot cover in step 5.
8. Close the computer case a ain.
9. Connect the CAN cable. Please note the wirin hints in chapter 5.
The first CAN interface (CAN net 0) has to be connected via the lower DSUB connector (X1)
and the second CAN interface (CAN net 1) has to be connected via the upper DSUB
connector (X3).
10. Connect the computer to mains a ain (mains connector or safety fuse).
11. Switch on the computer and the peripheral devices.
12. End of hardware installation.
Continue with the software installation.
