PC/104 DUAL CAN FIELD BUS INTERFACE CAN2-PC/104
The CAN2-PC/104 is a low-cost, high performance Intel 82527- based CAN interface board with an single or dual CAN field bus controller(s) for PC/104 expandable embedded systems. The CAN2 82527 serial communication controller chip(s) are I/O devices in the embedded system I/O address space for easy software service with most of the operating systems (i. e. Microsoft Windows 95, Windows 98, Windows NT, and Windows CE). The CAN2 offers CAN field bus access for PC/104 expandable embedded systems in high- speed CAN applications with up to 1 Mbps and in CAN field bus networks with up to 110 nodes.

The CAN2-PC/104 82527 serial communication controller supports the standard message frames with 11- bit message identifier according to the CAN specification 2.0 part A and the message frames with 29- bit message identifier of the CAN specification 2.0 part B. The 82527 has the capability to transmit, receive, and perform message filtering on CAN message frames with a 11- bit or 29- bit message identifier. The 82527 also supports CAN remote frames and CAN extended data/remote frames. The 82527 performs all the functions of the physical and data- link layers.

The CAN2 82527 serial communication controller(s) are I/O port mapped to the PC/104 host system I/O address space. The I/O base address is jumper selectable over the CAN2 chip select logic with jumper JP3 to 200h, 210h, 220h, 230h, 300h, 310h, 320h, or 330h. Each 82527 serial communication controller can generate an interrupt request to the PC/104 bus. This interrupt request is jumper selectable with jumper JP1 (for CAN2 Channel 1 - IRQ Select Channel 1) and jumper JP2 (for CAN2 Channel 2 - IRQ Select Channel 2) on the PC/104 bus interrupts IRQ2, IRQ3, IRQ4, IRQ5, IRQ6, IRQ7, IRQ10, IRQ11, IRQ12, IRQ14, or IRQ15. The CAN2 jumper configuration with the jumpers JP1, JP2, and JP3 is important for using the CAN2 in PC/104 based embedded systems together with real- time operating systems (RTOS). Most of this operating systems donīt use the Plug and Play methods.
