Chapter 1 Introduction
1.1 Summary
The CBI-4852A is a CAN (Controller Area Network) Interface board for CardBus-based computers. Two
high-speed communications channels compliant with ISO11898-2 are achieved with the SJA1000 CAN
controller (Royal Philips Electronics or equivalent) and the PCA82C250 CAN transceiver (Royal Philips
Electronics or equivalent). The maximum bit rate is 1 Mbps. Each channel provides independent
communications at individually set bit rates. With the large-capacity FIFO buffer, this board can
transmit/receive messages at high speed. A simple operation checks of CAN bus can be performed. By using
the JKC-4851A, the termination resistors can be connected.

1.1.1 Features
1. CAN protocol
The CBI-4852A can perform high-speed CAN communications compliant with the CAN 2.0B protocol
and ISO11898-2. This product uses the SJA1000 CAN controller (Royal Philips Electronics or equivalent)
and the PCA82C250 CAN transceiver (Royal Philips Electronics or equivalent). The maximum bit rate is
1 Mbps.
2. One CAN controller for each channel
The CBI-4852A incorporates one CAN controller per channel. Each channel provides independent
communications at individually set bit rates. The system clock frequency is 24 MHz.
3. High-performance CAN controller
By adopting the SJA1000 CAN controller, the following functions are provided:
error count, error code capture, two receiver message filters, etc.
4. Large-capacity FIFO buffer
The CBI-4852A incorporates 64 messages for transmit FIFO and 64 messages for receive FIFO per
channel. This feature reduces CPU load. It also allows you to transmit/receive messages at high speed
without data loss.
5. Pseudo message
Pseudo messages can be transmitted. By using this function, a specified pseudo message can be transmitted
in a fixed cycle. Simple operation checks of CAN bus can be performed.
6. CAN bus monitor
The CBI-4852A can monitor messages and error status which were transmitted to the CAN bus. It can also
confirm those timings to monitor by 10 µs. Moreover, it can configure response messages not to output.
This feauture helps you to monitor without loading to network.

3.5 CAN Controller Access
3.5.1 Basic Mode
The CBI-4852A can directly access all registers of the SJA1000 CAN controller. Moreover, an interrupt
request is issued for CardBus by the controller interrupt signal. Basic CAN mode and Peli CAN mode are
selectable.
•Basic CAN mode
It is the mode with the conventional PCA82C200 CAN controller (Royal Philips Electronics or
equivalent) and compatibility. The contents of a register and arrangement are the same.
•Peli CAN mode
It is the mode which added the extended function to the conventional CAN controller. It has such
function as 64 bytes of receive FIFO. More advanced communications control can be performed by using
an extended function.

3.5.2 FIFO Mode
In FIFO mode, the following functions are provided:
•Transmit message FIFO or pseudo message transmit for transmit
•Reseive message FIFO for receive
•Error status FIFO for error control
These modes require accesses to the CAN controller in the internal control. Therefore, direct accesses to some
part of registers of the CAN controller are forbidden.

Chapter 6 Glossary
6.1 List of Definitions
The list below explains a selection of technical terms used in this manual.
Term Definition
CAN CAN is an acronym for Controller Area Network.
Standardized by ISO as a serial communications protocol,
CAN was developed by the German electrical equipment
manufacturer, BOSCH, for use in automotive networks.
After being regulated by ISO, CAN soon became the
de-facto standard in the automobile industry.
CAN technology is now used in various other fields such as
factory automation, agriculture, medical equipment, nautical
craft, and also DeviceNet.
ISO11898-2 The high-speed CAN communications standard. The bit rate
range is between 125 kbps and 1 Mbps. It may not be
connected to a fault-tolerant CAN bus.
Terminating resistor The resistor used in order to minimize reflection of an
electric signal, also called a terminator.
Dominant A logical 0 is represented by the dominant bit. When a
dominant bit and a recessive bit are output simultaneously
by two different drivers on the same bus, only the dominant
bit is observed on the bus signal line.
Recessive A logical 1 is represented by the recessive bit. When the bus
is in the idle state, a recessive bit is observed on the bus
signal line.

Chapter 8 Troubleshooting
8.1 Checkpoints
Problem Solution
Double-check all cable connections.
Set up your equipment to meet the timing characteristics of this board, such
as data setup time, and input/output response time.
Data cannot be transferred
correctly.
If the power requirements exceed the system power budget, the circuits on
the board or connected external circuits cannot be driven properly. Prepare
an external power supply for your PCI board.
Communications are not
reliable. Transmit/receive
errors occur.
Check whether the selected terminating resistor is suitable for your system.
Refer to “3.4 External Input/Output Circuit,” page 8.
The computer does not
recognize this board.
Use the PCI device viewer (BPF-0801) to examine the CardBus card board
on your computer. Please send the result to our Technical Support Center
by fax or e-mail. The PCI device viewer may be downloaded from our Web
site free of charge.
The computer does not
response after Standby mode.
(Input and output are
disabled.)
Set the System standby setting to “Never”.
