Notes on J3 Signals COM1 – COM4 The signals on these pins are RS-232 level signals and may be connected directly to RS-232 devices. The pinout of these signals is designed to allow a 9-pin male IDC connector to be crimped onto the corresponding ribbon cable wires to provide the correct pinout for a PC serial port connector (DTE). LPT1 The signals on these pins comprise a standard PC parallel port. The pinout of these signals is designed to allow a 25-pin female IDC connector to be cr

6.3 Console Redirection to a Serial Port In many applications without a video card it may be necessary to obtain keyboard and monitor access to the CPU for configuration, file transfer, or other operations. Prometheus supports this operation by enabling keyboard input and character output onto a serial port (console redirection). A serial port on another PC can be connected to the serial port on Prometheus with a null modem cable, and a terminal emulation program (such as Hyperterminal) can

6.4 Watchdog Timer Prometheus contains a watchdog timer circuit consisting of two programmable timers, WD1 and WD2, cascaded together. The input to the circuit is WDI, and the output is WDO. Both signals appear on I/O connector WDI may be triggered in hardware or in software. A special “early” version of WDO may be output on the WDO pin. When this signal is connected to WDI, the watchdog circuit will be retriggered automatically. A block diagram is provided here: The
