The PCM-CAN100-D is a high price/performance ratio PCI-104 CAN module. It adopts CAN controller Phillips SJA1000T, transceiver 82C250, and follows ISO 11898-2 CAN standard. The PCM-CAN100-D provides 1 independent CAN bus communication port with 9-pin D-sub male connector and 1 bypass CAN port with 9-pin D-sub female connector. This special design helps users wire their CAN network more easily. Besides, The PCM-CAN100-D belongs to the PISO-CAN family. A lot of software resources can be applied, such as RTX driver, socket CAN driver, LabVIEW driver, DASYLab driver, Virtual CAN driver, CAN OPC, ActiveX element, CANopen master library, DeviceNet master library and so forth. Moreover, the utility tool is given for CAN data logger and CAN bus access. It is helpful to debug and test the CAN network. In order to building a CAN network application quickly, there are some demo programs with several development environment. These demos are good model for applying the PCM-CAN100-D, and can effectively reduce users’ development cycle time. Therefore, the PCM-CAN100-D is an economic and easy-to-use solution for various CAN applications.
