CAN-AC2

This is the CAN-board for the ISA-Bus offering two CAN ports (Highspeed). In

it’s standard hardware configuration it uses the Philips PCA 82C200 CAN

controller, which supports Standard Identifiers only. Piggyback modules are

available (one for each port) which replace the Philips CAN controllers by the

Intel 82527 CAN-controllers. The Intel controllers support both Standard and

Extended Identifiers. The board is a memory-mapped device and uses a 16

kilobyte big address range between 640k Byte and 1M Byte. We do not

recommend this board for new projects, use the CAN-AC2-PCI which is

described below instead. We will freeze the driver code for this board with the

release of R12. Softing has confirmed that no new firmware versions are

planned for this board either.

CAN-AC2-PCI

This is the CAN-board for the PCI-bus offering two CAN ports. The

CAN-controllers used on the board are the SJA1000 from Philips. In it’s

standard hardware configuration the board is designed for both Standard and

Extended identifiers for Highspeed CAN. Piggyback modules are available (one

for each port) which add Lowspeed CAN support in order to switch between

Highspeed and Lowspeed CAN controlled by the driver block. The board is a

memory mapped PCI device, which uses 64k Bytes of address space. The

address space is assigned automatically by the PCI BIOS of the target PC and

lies usually in the range between 2G bytes and 4G bytes. Any new projects

where a desktop PC is used as the target system should use this board and not

the ISA board described above.

CAN-AC2-104

This is the CAN-board for the PC/104-bus offering two CAN ports. The

CAN-controllers used on the board are the SJA1000 from Philips. The board

offers both Standard and Extended identifiers for Highspeed CAN. A Lowspeed

CAN hardware extension is not available. The board is both I/O-mapped and

memory-mapped. The I/O-mapped area uses a 3 bytes big address range and

the memory-mapped area uses a 16k bytes big address range between 640k

bytes and 1M bytes.
