I/O Hardware / SCALEXIO DS2671 Bus Board HighFlex board for interfacing to different bus systems Highlights n Supports CAN, LIN, and FlexRay bus systems n 4 fl exibly confi gurable channels n Onboard failure routing unit Application The DS2671 Bus Board is the interface between the dSPACE With its freely confi gurable channels, the DS2671 can serve Simulator and various bus systems. It has 4 multifunctional different bus systems for one ECU. The selected bus system channels, each of which can support a bus system that is can easily be changed from project to project because the assigned to it by software. channels can be completely confi gured by software. The following buses and protocols are supported: n FlexRay Other bus systems and protocols can be added on request. n CAN (high-speed & fault-tolerant) n LIN/K-line n RS232, RS422, RS485 n TLL–based protocols I/O Functionality Each channel on the DS2671 has a bus FPGA, all the stan- A different bus system can be used on each of the 4 chan- dardly supported transceivers for bus systems and protocols, nels on the DS2671. and a piggyback slot for customer-specifi c transceivers. The bus system controllers, which include certifi ed IP cores such For information on the failure simulation function, please as the Bosch E-Ray controller for FlexRay, are implemented refer to Failure Simulation on p. 8. on the bus FPGA. To use a bus system or protocol that is not yet standardly supported, you can install the necessary transceiver in the channel's piggyback slot. 18 2013 I/O Hardware / SCALEXIO Technical Details Parameter Specification General n 4 independent bus channels n Onboard failure routing unit (FRU) (p. 8) n Overvoltage and undervoltage protection for transceivers n Parallel termination resistors with overcurrent protection n Status LED for overall board status n Channel-specific LEDs for individual bus channels (inactive, ready for data transfer, data transfer running, error message) n One piggyback module slot per channel for a customer-specific transceiver Supported protocols/bus systems n FlexRay 2.1 (based on Bosch E-Ray) n High-speed CAN (ISO 11898-2) n Fault-tolerant CAN (ISO 11898-3) n LIN 2.0/K-line (ISO 9141) n RS232, RS422 and RS485 n TTL driver Internal communication interface n IOCNET Physical data Physical size n 410 x 100 x 15 mm (16.1 x 3.9 x 0.6 in) n Requires 1 slot Voltage supply n 24 V Order Information Product Order Number DS2671 Bus Board n DS2671 IOCNET I/O connector connection DC DC Fuse FRU Termination Controller Bus Piggy- or transceivers back Bus FPGA 4 .. . 1 Status LED LED 19 2013
