WDTB Specifications: Address Space: 4 I/O Addresses (200h-3FCh) Cable: 6" Reset Jumper Timeout Range: 10ms to 10 minutes (selectable) Size: 1/2 Card (8-Bit ISA) Power: 100 ma @ 5VDC Relay: 1 Form C (0.5 Amp) Connectors: 1-DB15M (external contact) 2-2 pin Headers (Internal RESET contact) Software: C, Turbo Pascal, Basic, DLL   $99.00 _____________________________________________ The WDTB has an independent crystal oscillator which drives a down counter IC. If the counter is allowed to decrement to zero, (no update from a crashed application program) a hardware pulse generator closes the on-board relay to generate a hard reset. An IRQ header allows a jumper selection to produce a hardware interrupt instead of a reset pulse.
