The National Instruments PCI-6602 Counter/Timer Device (Part Numbers: 777531-01, 184479-01) is a high-performance solution equipped with eight counters/timers and 32 bidirectional digital channels, making it ideal for a range of measurement applications. With a maximum source frequency of 80 MHz and compatibility with 5V TTL logic levels, the PCI-6602 excels in monitoring positions with quadrature encoders, counting events, totalizing data, and measuring time-related quantities. It features the NI-TIO, an application-specific integrated circuit (ASIC) designed to enhance timing and counting capabilities beyond conventional devices. The device features a 68-pin male SCSI-II type I/O connector, enabling robust connectivity. The PCI-6602 supports advanced functionalities including debouncing/glitch removal, buffered operations, and pulse generation. Notably, it incorporates pad synchronization, which aligns counters to external signals, ensuring that counters respond simultaneously to specific triggers. This device requires the NIDAQmx driver software for optimal operation and is compatible with software development environments such as LabVIEW and LabWindows/CVI. The PCI-6602 measures 6.9 by 3.9 inches and is designed for a recommended operating temperature range of 0 °C to 55 °C and a storage temperature range of -20 °C to 70 °C. While the PCI-6602 has announced a mature status, it remains available for purchase and repair through Apex Waves.
