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.

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.

5.4 Multiple CardBus Cards

When using multiple cards in one system, it is required to write the CardBus ID number to the ROM in the card. The CardBus ID configuration utility program in the software can configure the number. Refer to Help files for more details.

Notes:

• Write the configured CardBus ID number on the back side of each card to easily confirm the number.

• Please download and use the newest version about software.

The following example shows the CardBus ID number is “0.”

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

Data cannot be transferred correctly.

Communications are not reliable. Transmit/receive errors occur. The computer does not recognize this board.

The computer does not response after Standby mode. (Input and output are disabled.)

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. 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. Check whether the selected terminating resistor is suitable for your system. Refer to “3.4 External Input/Output Circuit,” page 8.

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. Set the System standby setting to “Never”.
