  • Page 25 WARNING If you connect power incorrectly, the module will almost certainly be damaged or destroyed. Such damage is not covered by the RTD warranty! Please verify connections to the module before applying power. Power is normally supplied to the cpuModule through the PCIe bus connectors (CN1 or CN2). If you are placing the cpuModule onto a PC/104 stack that has a power supply, you do not need to make additional connections to supply power.

    This RTD cpuModule uses onboard flash to store user BIOS settings. To preserve compatibility with traditional PCs, the RTD Enhanced BIOS also mirrors the user settings from flash in CMOS. Therefore, the contents of CMOS may be overwritten at boot time, and should be treated as “read only”.

    The Advanced Watchdog Timer has a Setup Register and a Runtime Register. The Setup Register is set by the BIOS, and can be adjusted by entering the BIOS Setup Utility, and going to “Advanced/Miscellaneous RTD Features”. The Setup Register may also be read by the driver to determine if the Watchdog is enabled, and the interrupt and base address that it is using.

    RTD modules installed in IDAN frames are called building blocks. IDAN building blocks maintain the simple but rugged stacking concept of PC/104 and PC/104-Plus. Each RTD module is mounted in its own IDAN frame and all I/O connections are brought to the walls of each frame using standard PC connectors. No connections are made from module to module internal to the system other than through the PC/104 bus, enabling quick interchangeability and system expansion without hours of rewiring and board redesign.
