The National Instruments part number 779497-01 refers to the PCI-1588 Synchronization Device, designed for precise timing and synchronization applications. This device is equipped for a single PCI slot and operates using the IEEE 1588-2008 precision time protocol, allowing for effective clock and event synchronization with other IEEE 1588-compatible devices. The PCI-1588 can be configured as either a master or slave clock within an IEEE 1588 network. An integrated FPGA automatically calibrates the frequency and phase of its clock, ensuring high fidelity in synchronization processes. Communication with other IEEE 1588 devices is facilitated via a built-in Ethernet port that automatically negotiates speeds of either 10 or 100 Mbps. The device also supports synchronization with non-IEEE 1588 systems, such as traditional instruments or PLCs, through general-purpose Programmable Function Interface (PFI) lines and SMB connectors located on the PCI bracket. Additionally, the Real-Time System Integration (RTSI) interface enables seamless synchronization with other PCI instruments within the host computer. The front panel includes an RJ-45 Ethernet connector, three PFI connections (PFI0, PFI1, PFI2), and LEDs that indicate Ethernet link status and operational speed. The NI 779497-01 is capable of timestamping incoming signals, enhancing its utility in demanding synchronization tasks. To operate this device, the NI-Sync driver software is required, with compatibility across multiple application development environments, including LabVIEW, LabWindows/CVI, and Visual C/C++.
