系统插槽链路2是到853-041348-780交换机2的Gen-2 x16 PCI Express链路，在系统控制器插槽和853-041348-780交换机之间提供8 GB/s（单向）的标称带宽。PXI Express外围插槽11-18通过Gen-2 x8 PCI Express链路连接到PCI Express交换机2，并且位于系统插槽链路2的下游。PCI Express到PCI桥2连接到PCI Express交换机2，并为混合外围插槽11-18提供32位、33MHz的PCI总线。系统控制器插槽还可以连接到一些PXI功能，如：853-041348-780和PXI Local Bus 6。默认情况下，系统控制器将使用PS_ON#信号控制电源。此线路上的逻辑低将打开电源。
853-041348-78012 GB/s系统控制器插槽是机箱的插槽1，是CompactPCI Express和PXI Express规范定义的2链路配置系统插槽。它有三个系统控制器扩展插槽，用于比一个插槽宽的系统控制器模块。这些插槽允许系统控制器向左扩展，以防止系统控制器使用外围插槽。背板使用Gen-2 x8和Gen-2 x16 PCI Express链路将系统插槽连接到两个PCI Express交换机。这些交换机将PCI Express连接分配到外围插槽和两个PCI Express到PCI桥，以向混合外围插槽提供853-041348-780总线。有关853-041348-780系列体系结构的概述，请参阅图1-3。系统插槽链路1是到PCI Express交换机1的Gen-2 x8 PCI Express链路，在系统控制器和PCI Express交换机之间提供4 GB/s（单向）的标称带宽。PXI Express外围插槽2-10通过Gen-2 x8 PCI Express链路连接到853-041348-780交换机1，并且位于系统插槽链路1的下游。PCI Express到PCI桥1连接到PCI Express交换机1，并为混合外设插槽2-9提供32位、33 MHz的PCI总线。
Multiple pages of variables can be created, each with useful parameters for various troubleshooting or tuning procedures.853-041348-780 The user can toggle between pages depending on the task being performed. Control Configuration and Set Point Management—Watch Window can upload or download all tunable variables from the control system. This feature allows a user 853-041348-780(e.g., fleet owner, distributor, packager) to upload (and save) all tunable parameters from one control and download the same settings to other controls for similar engine configurations.853-041348-780 Program Loading—Watch Window provides services to download a new program to the control853-041348-780. 853-041348-780This is available in the Professional version only
853-041348-78012 GB/s The system controller slot is Slot 1 of the chassis and is a 2-Link configuration system slot as defined by the CompactPCI Express and PXI Express specifications. It has three system controller expansion slots for system controller modules that are wider than one slot.853-041348-780 These slots allow the system controller to expand to the left to prevent the system controller from using peripheral slots. The backplane connects the system slot to two PCI Express switches using a Gen-2 x8 and a Gen-2 x16 PCI Express link. These switches distribute PCI Express connections to the peripheral slots and to two PCI Express-to-PCI bridges to provide PCI buses to the hybrid peripheral slots.853-041348-780 Refer to Figure 1-3 for an overview of the NI PXIe-1085 Series architecture.
The 853-041348-780 Series chassis combines a high-performance 18-slot PXI Express backplane with a high-output power supply and a structural design that has been optimized for maximum usability in a wide range of applications. The chassis’ modular design ensures a high level of maintainability, resulting in a very low mean time to repair (MTTR). The NI PXIe-1085 Series chassis fully complies with the PXI-5 PXI Express Hardware Specification, offering advanced timing and synchronization features. The key features of the NI PXIe-1085 Series chassis include the following: High Performance for Instrumentation Requirements • 853-041348-780 12 GB/s chassis—Up to 4 GB/s (single direction) per PXI Express slot dedicated bandwidth (x8 Gen-2 PCI Express). • NI PXIe-1085 24 GB/s chassis—Up to 8 GB/s (single direction) per PXI Express slot dedicated bandwidth (x8 Gen-3 PCI Express). • 38.25 W per slot cooling meets increased PXI Express cooling requirements • Low-jitter internal 10 MHz reference clock for PXI/PXI Express slots with ± 25 ppm stability • Low-jitter internal 100 MHz reference clock for PXI Express slots with ± 25 ppm stability • Quiet operation for 0 to 30 °C at 51.2 dBA • Variable speed fan controller optimizes cooling and acoustic emissions • Remote power-inhibit control • Complies with PXI and CompactPCI Specifications853-041348-780
