Hardware Installation
Before You Begin
Before you begin, take a minute to ensure that your package includes the required components that should
have shipped with your CANpro/104-Plus Opto.
●One CANpro/104-Plus Opto CAN controller board
●One CD containing documentation
If anything is missing, contact Connect Tech or your reseller. Also, visit the Download Zone of the Support
Center on the Connect Tech website for the latest product manuals, installation guides, diagnostic utilities and
device driver software.
Installing the CANpro/104-Plus Opto Into Your System
Turn off the power to your embedded computer and open any enclosures needed to access the PC/104-
Plus or PCI-104 expansion connectors.
Carefully insert the board into the PC/104-Plus or PCI-104 connector.
Set the ID rotary switch accordingly (see Table 1).
Set the correct on-board jumpers for each CAN port (J1 –J6) (see pages 9-10 for more details).
Power on your embedded computer and install the appropriate drivers for your operating system.

PCI Interrupt, Clock and ID Selection
The following PCI signals, (INTA#, INTB# INTC# INTD#), (CLK0, CLK1,
CLK2, CLK3), (IDSEL0, IDSEL1, IDSEL2, IDSEL3), are selected by using the
Rotary Switch on the CANpro/104-Plus Opto board (RSW1). Selections need to
match the stack location of the CANpro/104-Plus Opto in your PC/104-Plus
stack. See Table 1 below for more details.

On-Board Jumper Configuration
Figure 3: CAN Ports and Jumper Locations
120 Ohm Termination Jumpers
Jumpers J1 and J4 will enable a 120 Ohm termination resistor across the CAN-H and CAN-L lines.
Termination is always recommended for improved signal integrity, especially for long transmission lines.
Termination requirements should be evaluated on a case by case basis. Typically both ends of a CAN bus are
terminated, but termination is not enabled on cards that sit in the middle of the bus. See Figure 4 and Figure 5
for examples that indicate when to use this jumper selection.
Figure 4: Example –CANpro/104-Plus Opto at the end of a CAN bus
NOTE:
The 120 Ohm termination jumper must be installed in this
situation.

Figure 5: Example CANpro/104-Plus Opto in the middle of the CAN bus
NOTE:
The 120 Ohm termination jumper does not need to be installed
in this situation.
Slew Rate Control Jumpers
Installing a jumper on J2 or J5 (see Figure 3) will disable slew rate limiting for the associated CAN port. Slew
rate limiting will reduce the emitted switching noise that is sent out onto the CAN bus lines and radiated from
those lines. Switching noise may cause EMI/EMC incompatibilities depending on the cabling used to support
the system. The use of slew rate limiting may aid in a system that is nearing the maximum limit of emissions.
Properly shielded cabling will also dramatically reduce emissions. Slew rate limiting may only be used on
busses operating at slower baud rates. With the jumper installed, full 1Mbps operation is possible.
DB-9 Frame Ground Connect
CANpro/104-Plus Opto models that have DB-9 connectors, will allow you optionally enable the Frame
Ground to be tied to ports isolated ground plane with J3 and J6.

Software Configuration
The information provided below is intended for advanced users and developers that wish to create their own
custom drivers. Typical CANpro/104-Plus Opto users will used the driver provided by Connect Tech.
PCI Properties of CANpro/104-Plus Opto
The CANpro/104-Plus Opto card will appear in your system with the following PCI information:
Vender ID: 0x10b5
Device ID: 0x9030
SubVender ID: 0x12c4
SubVender Device ID: 0x900
CAN Controller Address Space
CAN controllers are mapped on the PLX 9030 PCI Base Address 2 (BAR2) to Local Address Space 0. This
address space is re-mapped to a local offset of 0x00. Each CAN controller is allotted 256 bytes of address
space. CAN controller #1 has a local address range of 0x000 - 0x0FF, while CAN controller #2 has a local
address range 0x100 –0x1FF. See below for the full address/register allocation details in both BasicCAN and
PeliCAN modes.

CAN Controller Interrupts
Each CAN controller is tied to a local interrupt on the PLX9030 which is then forwarded to a single interrupt
on the PCI bus. Access to the PLX9030 interrupt control/status register can be done by accessing the
INTCSR register at offset 4Ch from the PCI base address of the CANpro/104-Plus Opto.
This diagram is taken from the PLX9030 Data Book v1.4.
GPIO Details
GPIO Header
CANpro/104-Plus Opto includes a 10-pin header with 8-bits of 3.3V General Purpose IO. The location and
