Kvaser PCcan HS√

 

Hardware

• The board is a quarter-size (length 135 mm) 8-bit ISA bus board and occupies 64 bytes of I/O space. The base address can be any of 200H, 240H, 300H, and 340H. The interrupt signal on the CAN controllers can be 连接ed - under software control - to any one of IRQ 2/9, IRQ 3, and IRQ 5 on the ISA bus.
• The original 16 MHz oscillator may be replaced with an oscillator of frequency range 1-24 MHz to obtain the required bit rate on the bus. The PCcan 4xHS board draws approximately 600 mA at 5V.
• The industry-standard CAN controllers on the PCcan cards are directly accessible to the programmer. This makes the cards suitable for cross-platform development: you can develop your software on your PC and then move it, with a minimum of 改变s, to your embedded system.
• The CAN controllers support CAN 2.0 A and 2.0 B (active.) The CAN bus drivers supports the standard, high-speed ISO11898 physical layer.

External Connector

• The outputs from the CAN circuits are 连接ed to female D-SUB 连接器 via optocouplers and bus drivers (Philips 82C251, conforming to ISO 11898).
• The 连接器 provide the voltage feed for the bus section (optocouplers and driver circuits). Alternatively the PC is used as power source; however this gives no galvanic separation between the computer and the CAN bus.
• On the PCcan 4xHS card, it is possible to 连接 all the 4 CAN in/outputs to a common CAN bus, which is also 连接ed to the CAN-连接or.
