1. Overview
1.1 Description of the Module
Fig. 1.1: Block circuit diagram of CAN-PCI/266
The CAN-PCI/266 is a passive PCI-bus board for 66 MHz PCI-bus systems with one or optional two
CAN-interfaces. The CAN-PCI/266 works with a bus width of 32 bits. The module can also be used in
33 MHz PCI-bus systems at a bus speed of 33 MHz.
The ISO 11898 compliant CAN-interfaces allow a data transfer rate of 1 Mbit/s. Among many other
features the bit rate can be parametrised by software.
The CAN interface is electrically isolated from the other potentials by optocouplers and DC/DC-
converters.
Optional the board can be delivered with DeviceNet interface or Single-Wire interface.
The CAN-PCI-266-2 (with two CAN-interfaces) is equipped with four LEDs in the front panel.

2. Hardware Installation
Attention!
Electrostatic discharge may cause damage to electronic devices. In order to avoid this please follow
the instructions below before you touch the CAN module to discharge your personal static electricity:
@Switch off the power supply of your PC but leave the connector plug in the socket.
@Then touch the metal case of the PC to discharge the static electricity.
@Furthermore you must avoid contact between your clothes and the CAN module.
Execute Hardware Installation:
1. Switch off the PC and allconnected peripheral devices (monitor, printer, etc.). Switch off the CAN
devices of the net to which the CAN module is to be connected.
2. Discharge yourself as described above.
3. Disconnect the power supply of the PC from the mains.
4. Remove the PC cover.
Unfasten the mounting screws at the back of the PC and remove the cover.
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 fixing the module afterwards.
The CAN module can be inserted into every PCI slot. Be careful not to insert the board into an ISA
slot, because this can damage the PC and the board!
6. Insert the CAN module 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. Replace the PC cover.
Secure the cover with the screws you removed in step 4.

9. Connect the CAN wire.
Please note that the CAN bus has to be terminated at both ends!
esd offers special T- connectors and terminator connectors. Additionally the CAN_GND signalhas
to be connected to earth at exactly one point. For easier wiring the termination connectors are
equipped with an earth connector (4.8 mm fast-on, male).
A CAN participant without an electrically isolated interface acts as an earth connection.
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. Reconnect the power supply of the PC.
11. Switch on the PC, the peripheral devices and the other CAN participants in any order.
12. End of hardware installation.
Continue with the software installation as described in the manual ‘CAN-API, with Software Tools
and Installation Notes’.

6. Correctly Wiring Electrically Isolated CAN Networks
Generally all instructions applying for wiring regarding an electromagnetic compatible installation,
wiring, cross sections of wires, material to be used, minimum distances, lightning protection, etc.
have to be followed.
The following general rules for the CAN wiring must be followed:
1.
A CAN net must not branch (exception: short dead-end feeders) and has to be terminated
by the wave impedance of the wire (generally 120 Ω±10%) at both ends (between the
signals CAN_L and CAN_H and not at GND)!
2.
A CAN data wire requires two twisted wires and a wire to conduct the reference potential
(CAN_GND)!
For this the shield of the wire should be used!
3. The reference potential CAN_GND has to be connected to the earth potential (PE) at one
point. Exactly one connection to earth has to be established!
4. The bit rate has to be adapted to the wire length.
5. Dead-end feeders have to kept as short as possible (l < 0.3 m)!
6. When using double shielded wires the external shield has to be connected to the earth
potential (PE) at one point. There must be not more than one connection to earth.
7. A suitable type of wire (wave impedance ca. 120 Ω±10%) has to be used and the voltage
loss in the wire has to be considered!
8. CAN wires should not be laid directly next to disturbing sources. If this cannot be avoided,
double shielded wires are preferable.

Cabling
for devices which have only one CAN connector per net use T-connector and dead-end feeder
(shorter than 0.3 m) (available as accessory)
Figure: Example for correct wiring (when using single shielded wires)
Terminal Resistance
use external terminator, because this CAN later be found again more easily!
9-pin DSUB-terminator with male and female contacts and earth terminal are available as
accessories
Earthing
CAN_GND has to be conducted in the CAN wire, because the individual esd modules are
electrically isolated from each other!
CAN_GND has to be connected to the earth potential (PE) at exactly one point in the net!
each CAN user without electrically isolated interface works as an earthing, therefore: do not
connect more than one user without potential separation!
Earthing CAN e.g. be made at a connector

Installation and Technical Data CAN-PCI/266 Rev. 1.1 15
Wire Length
Optical couplers are delaying the CAN signals. By using fast optical couplers and testing each
board at 1 Mbit/s, however, esd CAN guarantee a reachable length of 37 m at 1 Mbit/s for most
esd CAN modules within a closed net without impedance disturbances like e.g. longer dead-end
feeders. (Exception: CAN-CBM-DIO8, -AI4 and AO4 (these modules work only up to 10 m
with 1 Mbit/s))
