The AS-Interface Programmer provides support for implementing Renesas' AS-Interface ICs, including the ASI4U and SAP51/SAP5S. An easy-to-use graphical user interface allows control of the AS-Interface functionality; e.g., EEPROM programming, telegram-by-telegram debugging for AS-Interface networks, and configuration or reading of the digital parameter port and input/output ports. An actual AS-Interface network can also be controlled digitally via the graphical interface.
