Description
The 6700U is a high performance data acquisition enclosure supporting high aggregated rate of up to 16M samples per second for high channel-count, high sample rate systems.
The 6700U enclosure has 16 slots for Series 6700 input and output modules with a Universal Serial Bus (USB 3.0) computer interface for programming, control and data output. For larger systems, up to 64 enclosures may be combined using USB 3.0 hubs or a computer with multiple USB 3.0 ports. The enclosures are 8U 19-inch rack-mount and have integral fans providing air circulation and an internal cable tray that routes the input and output cables from the front of the installed modules to exit the rear of the enclosure. The 6700U is an enhanced version of the 6000U enclosure using improved power supplies. It is lighter, more rugged and offers ultimate reliability and performance.
A sample clock bus is provided for multi-rack installations. Control and data transfer interface is USB 3.0, which provides high data transfer rates with low, predictable latency, readily available on most PC computers, including laptops. Maximum length of the interface cable is 3 meters but it may be extended further using Ethernet with the Control & Data Processor (CDP) option or a USB to Fiber/Ethernet extender.
Data Recording Redundancy is optionally available. A 2.5" HD (Model 6695) mounts on the USB controller board in each 6700U enclosure and provides a redundant recording point for the DAS. In the unlikely event the Operators Workstation or DAS Software fails, data will continue to record in each enclosure and can be recovered from the system post test.
The Control & Data Processor (CDP) interfaces multiple 6700U enclosures to gigabit Ethernet providing remote and/or distributed operation. The CDP is typically installed with the Series 6700 DAS and provides an Ethernet interface to the Operators Workstation. The CDP includes a high-speed processor and software that performs low-level operations, freeing resources on the Operators Workstation computer for data display, storage, distribution and reduction.
The Operators Workstation (PCCOWU-DHD) is the primary control and data recording point for the Series 6700 DAS. The PCCOWU-DHD is typically installed in the control room and runs PI660 Data Acquisition Software for system setup, calibration, display, recording, distribution and export. In installations where the DAS is not remote from the Operators Workstation, the PCCOWU-DHD will connect directly to Series 6700 Enclosures and does not require the CDP.
