Upon detection of an out-of-tolerance condition, the board is reset. This action is critically important in order to detect brownout or power fail conditions. The reset circuit also ensures that the power is nominal before executing a power-on reset.

As the approved IEEE-961 standard, the STD Bus is pop- ular worldwide. It provides a simple-to-use I/O bus in a small card size (4.5 x 6.5-inches). The cards mount securely in card cages that can tolerate shock and vibra- tion which makes them ideal for rugged industrial applications. STD Bus Card Cages & Backplanes - WinSystems has a wide selection of backplanes, assembled card cages, and powered racks. These units are designed to provide the high- est integrity and reliability needed as a foundation for an embed- ded system. Typical PC/104 and PC/104-Plus Module Stack The backplanes and card cages work with STD Bus processors from the original Z80 to the newest Pentium PC/104 and PC104-Plus Bus - The MCM/LPM-TX sup- CPUs.

PC/104 modules are very compact, measuring only 3.6 x 3.8 inches, and are offered by WinSystems and a number of third party companies worldwide. Module functions include spe- cialty serial I/O, digital I/O, 10/100 Ethernet, GPS, modem, audio, SCSI, etc. For more information and a specification on the PC/104 and PC/104-Plus Bus, refer to WinSystems' Volume 2 or Volume 3 Data Book or write the PC/104 Consortium. Multi-I/O Connector - WinSystems offers the optional CBL-247-1,Multi-I/O cable adapter for the COM1,COM2, LPT1 and keyboard. These four ports are combined into one 50-pin header at the edge of the board. The CBL- 247-1 is a 1-foot adapter cable that offers a more con- venient termination. COM1 and COM2 are 9-pin male "D" connectors with strain relief. LPT1 is a 25-pin "D" female socket with strain relief. The keyboard is a standard SDK2-STD-CX15-D Software Developers Kit 5-pin PS/2 connector socket. The power supply is a 80-Watt universal switcher that will accept input voltages from 85 VAC to 264 VAC. Output volt- ages are +5 volts at 12A, +12 volts at 3A, and -12 volts at 1.0A. The power supply, floppy disk and hard disk are mounted in a black anodized enclosure. The packaging permits easy access to the board, PC/104 modules and peripherals during program development.
