The National Instruments part number 781497-01 refers to the cDAQ-9191 CompactDAQ Chassis, a robust and versatile solution for data acquisition applications. This chassis features a single slot designed to accommodate C Series modules, enabling measurement of a diverse range of analog and digital I/O signals and sensors. The cDAQ-9191 is equipped with four counters and a timing resolution of 12.5 nanoseconds, ensuring precise timing for measurement tasks. The device supports Wi-Fi connectivity, adhering to the highest standards of network security as defined by IEEE 802.11i (WPA2), which includes comprehensive network authentication and data encryption methods. Specifically, the 781497-01 implements IEEE 802.1X authentication to restrict access to authorized devices, alongside advanced encryption protocols such as the Advanced Encryption Standard (AES), enhancing data security during wireless transmission. With an input FIFO size of 127 samples and a maximum output FIFO size of 8,191 samples for onboard regeneration, the chassis can efficiently handle data throughput. Additionally, it supports multiple Extensible Authentication Protocol (EAP) methods for seamless mutual authentication between data acquisition devices and wireless access points. When connected to a network, the cDAQ chassis allows access to multiple users. To perform data acquisition functions with C Series modules, including reset and self-test functions, the chassis must be reserved within National Instruments Measurement & Automation Explorer (MAX).
