The National Instruments PC-TIO-10 is an ISA bus timing and digital I/O interface card for PC-based measurement and control systems. It integrates two AMD Am9513A System Timing Controllers for precise timing functions and one Motorola MC6821 PIA for digital I/O operations. The card delivers pulse measurement, wave generation, frequency shift keying, pulse-spread measurement, event duration recording, and counter functions across multiple timing modes.
