Installation
2 Installation
2.1 Hardware installation
For all work on the PC and interface, you must be statically discharged. The work
must be carried out on an earthed, anti-static work-mat.
Carry out the following work in sequence:
(1) Establish a free memory segment on the PC of at least 16 kbyte in the range
< 1MB (ISA memory range) and a free IRQ. For this, read the manual of
your PC.
(2) Set this memory segment and the IRQ on the interface, as described in Sec-
tion 3.1.
(3) Switch off the PC and remove the mains plug.
(4) Open the PC according to the instructions of the PC-manufacturer and de-
termine a suitable plug-in space.
The interface is designed according to the PC-standard and can be easily
built into the computer. Do not use force when plugging in.
(5) Ensure that the interface is held safely in place in the PC.
(6) If your interface is assembled with 2 separate CAN circuits, you must fix the
additional slot plate and plug in the header on the interface (see Section
3.2).
(7) Close the PC; the hardware installation is now completed.
2.2 Software installation
To operate the interface, a driver is required. For the installation of the CAN driver
VCI please read the VCI installation manual.

3.1.1 Setting the base address
To set the base address the switches 1 to 4 of the DIP switch SW1 are used. The
following table shows the possible settings (default = factory setting).

The address zone of the interface must not overlap with any other sys-
tem components in the PC.
3.1.2 Setting the PC interrupt
The required interrupt is set with the jumper board JP1 by connecting the jumper
pair belonging to the requested IRQ.
Only one interrupt may be selected for the iPC-I 165!
If no interrupt is required, no pin may be bridged on JP1. The factory setting of
the interface is IRQ 5.

Configuration
It should be ensured that no other system component is occupying the selected
interrupt, except for cards which work with shared interrupts.
In PC systems it is possible that several cards share an interrupt. Further informa-
tion on this subject can be found in the hardware manuals for the PC. The
iPC-I 165 supports shared interrupts by enabling the level of the interrupt im-
pulses to be adjusted with switch 2 of the DIP switch SW3. For shared interrupts
the DIP switch SW3-2 must be set to OFF position.
IRQ level SW3
2
Low impulse (default) OFF
High impulse ON
3.1.3 16 bit access mode
By setting the switch 5 of DIP switch SW1 to OFF, the 16 bit access for the
iPC-I 165 can be activated. Then iPC-I 165 will be accessed with 16 bit bus cycles
from the ISA bus. If the 16 bit access is switched off the interface is accessed with
8 bit wide bus cycles.
Access mode SW1
5
16 bit (default) OFF
8 bit ON
3.1.4 Zero wait states
By setting the switch 6 of DIP switch SW1 to OFF, a shortened ISA bus cycle (0
wait states) can be activated. If SW1-6 is set to ON, the PC performs a standard
bus cycle.
Wait states SW1
6
No wait states OFF
With wait states (default) ON

Configuration
3.1.5 Bootstrap loader
With switch 7 of DIP switch SW1 set to ON, the integrated bootstrap loader of
the SAB C165 is activated after a hardware reset. The bootstrap loader is de-
scribed in detail in the user manual of the SAB C165.
Bootstrap loader SW1
7
Not activated (default) OFF
Activated ON
3.1.6 Reserved switches
Switch 8 of DIP switch SW1 must remain in OFF position, otherwise the board
will try to execute program code on the EEPROM (which is not available anymore
at the actual version of the iPC-I 165).
If the DIP switch SW3 is assembled, only the switch 2 (interrupt level) may be
changed by the user. Switches 1, 3 and 4 of DIP switch SW3 must remain in OFF
position.
If one of these switches is changed the board may not work properly!
3.1.7 Providing current supply via CAN plug
With the solder jumpers JP4, JP5, JP6, JP26, JP27 and JP28, the VCC (5V) or GND
signals can be connected to the CAN plug of the two CAN circuits. For this, the
jumpers given in the following table have to be closed.

3 - GND Closed JP4 JP26
6 - GND Open JP6 JP27
9 - VCC Open JP5 JP28
If the bus transceiver is electrically isolated, GND and VCC are also connected
electrically isolated from the interface to the plug board via the solder jumpers.

Configuration
3.1.8 Bus termination resistors
The iPC-I 165 has termination resistors for the CAN bus. By closing the solder
jumper JP8 (1st CAN) resp. JP7 (2nd CAN) these resistors are connected to the
CAN high and CAN low line. The value of the resistors is 120 Ohm. By default the
termination resistors are not connected.
3.1.9 Reset button and LED
The developer version of the iPC-I 165 is delivered with reset button SW2 and LED
D6. The LED is controlled by the microcontroller port P3.13 (LED on = bit set to
1).
3.2 Design of the CAN plugs
3.2.1 CAN bus connector
One (common) or two independent bus connectors according to ISO/IS 11898
can be installed on the iPC-I 165. The signals of the 1st bus connector are pro-
vided by the 9 pole sub-D plug/sleeve. If two independent bus connectors are
installed the signals for the CAN bus of the 2nd bus connector are provided by
the connector JP19. Both of the CAN interfaces can be optionally galvanic de-
coupled from the CAN bus.
As another option a version without any bus connector on the board is available.
In this case the signals are provided by separate connectors (X8 / X9 for the 1st
CAN, X10 / X11 for the 2nd CAN circuit).
As an option for iPC-I 165 a CAN protection circuit is available. The circuit keeps
disturbances and short spikes on CAN lines away from the electronics of the
iPC-I 165.
The first CAN line is connected to the 9 pole pin/sleeve X4/X5 via the plug con-
nectors X8 and X9. If both CAN controllers are installed and connected together
then they will be connected via these plug, too.
The second CAN line is connected to JP19 via the plug connectors X10 and X11.
If the ISO/IS 11898 bus interface is already installed on-board, the plug connec-
tors X8/X9 and X10/X11 are not present.

If the CAN protection circuit is installed on the board the signals CAN low and
CAN high of X9 (X11) are connected to X4/X5 (JP19) via the protection circuit.
The pin assignment of the SUB D9 connector/sleeve connected to JP19 is equal to
the pin assignment of the first CAN line (see page before).

EMC test
The PC/CAN interface iPC-I 165 has to be used only in a CE compliant PC. The
case of the PC should be sealed up against high frequency electrical noise. Use
only shielded cables for connecting the PC/CAN interface to the CAN bus and
connect the cable shield to the connector case. The connector case has to be
sealed up against high frequency electrical noise. All unused connectors of the
PC/CAN interface have to be closed with a cover which is sealed up against high
frequency electrical noise and ESD.
