CPC–104M is a passive CAN interface module for PC–104 based systems. Designed for industrial series applications CPC-104M has a robust and cost efficient construction. CPC–104M supports up to four NXP SJA1000 CAN controllers. CPC-104M maps the CAN controller into the PC address space and thus allows access to CAN messages with low latency. Existing software for the supported CAN controller can easily be adapted. With CPC-104M the CAN communication may be handled either in interrupt controlled or in polled mode, the interrupt channels 3-7, 9-12, 14 and 15 are available. CPC-104M can optionally be delivered with galvanic decoupling to the CAN bus. In this case power for the DC/DC converter is derived from the +5V PC-104 line. CPC-104M is available in different configurations regarding CAN channel count and galvanic decoupling.
|Pin assignment||Connector DSub 9, complying to CiA DS-102|
|Type of the physical connection||ISO 11898 / Transceiver PCA82C251|
|Voltage on bus connections||-30||+30||V|
|Isolation voltage with galvanic separation||-500||+500||V|
Any (also temporary) stress in excess of the limiting values may cause permanent damage on CPC-104M and other connected devices. Exposure to limiting conditions for extended periods may affect the reliability and shorten the life cycle of the device.
The configuration of the used address space and interrupt is done by jumper settings.
|Base address||1536 Bytes in the range of 0C0000h - 0DFFFFh, adjustable in steps of 1 kByte|
|Interrupt||One interrupt within the range of 3-7, 10-12, 14-15|
CPC-104M is mapped into the memory space of the PC with a base address in the area of C0000h to DE000h and occupies 1536 bytes. Through the availability of the CAN controller in the memory address space the CAN communication takes place directly and with low latency time. The memory occupied by CPC-104M is divided into two subranges. The first subrange encloses the configuration registers of the card and begins with the base address. The second subrange allows the access to the CAN controller.
