National Instruments 777918-01 Counter/Timer Device
The part number 777918-01 from National Instruments is the identifying part number for the PCI-6601 Counter/Timer Device. This counter device is designed to be used with the PCI bus system. It offers four 32-bit counters/timer channels and up to 32 lines of individually configurable, TTL/CMOS-compatible digital I/O. Each timer is capable of performing various time-related measurements including event counting, time measurement, frequency measurement, encoder position measurement, pulse generation, and square-wave generation.
This device has two internal time bases of 20 MHz and 100 kHz to provide precise timing references, with 20 MHz timebase is particularly useful for high-resolution timing applications, while the 100 kHz timebase offers lower resolution for less demanding tasks. This module also provides up to 32 lines of digital I/O that are TTL/CMOS-compatible and can be individually configured as inputs or outputs. These digital I/Os can be used to perform pattern generation, and pattern acquisition from other connected devices.
The 777918-01 is fully compatible with the National Instrument's NI-DAQ driver software which provides an extensive library of functions for digital I/O, counter/timer operations, and data acquisition. The device is also compatible with LabVIEW, LabWindows/CVI, and other NI software tools. To enable high-speed direct memory access transfers between the device and the host computer, the 777918-01 features the MITE PCI interface that helps reduce CPU load and improve overall system performance. It also supports the scatter-gather DMA which helps in handling large datasets acquired by the module.
The 777918-01 has an operating temperature range of 0 degrees Celsius to 55 degrees Celsius and a storage temperature range of -20 degrees Celsius to 70 degrees Celsius. The device supports a relative humidity range of 10% to 90%, non-condensing, for operation, and 5% to 95%, non-condensing, for storage. The 777918-01 complies with several international safety and electromagnetic compatibility (EMC) standards, to help ensure safe and noise-free operation of the device for accurate data acquisition and processing. This device is completely switch-free and jumperless and can only be configured via its compatible NI-DAQ driver software.
