“The μPAC-5001D-CAN series is palm size PACs (Programmable Automation Controller), including μPAC-5001D-CAN1 and μPAC-5001D-CAN2. With abundant and various peripherals and communication ports, the μPAC-5001D-CAN series can integrate different communication interface, like CAN bus, RS-232, RS-485, Ethernet and so on. In order to increase the modules openness and applications flexibility, the μPAC-5001D-CAN series provides DOS-like real-time single-task operation system for adapting to all kinds of needs. Users can develop application programs via C/C++ compiler. In respect of application development, the μPAC-5001D-CAN series provides various libraries and demo programs about the peripheral components. Users may be confused how to use those abundant libraries. For that purpose, they also provide demo programs about libraries. When users need to use various peripheral like communication ports, watch dog, real-time clock (RTC), seven-segment display, reading/accessing into flash, EEPROM, MircoSD, even using 64-bit hardware unique series number to protect the development of application software, they can be completed easily and quickly to meet all kinds of needs for application program development by revising and combining these sample programs. In order to work under harsh environment, the μPAC-5001D-CAN series was designed with low power consumption and fanless products. Besides, they add all manner of anti-jamming protection components on circuit design and meet requirements of the wide operating temperature and wide operating voltage. Basis of all features which be described previously, the μPAC-5001D-CAN series are ideal for data collection applied to integrate all kinds of communication interface or as a data processing center. They are also designed to convert different protocol network such as gateway or bridge devices.
