Description
The National Instruments PCIe-8381 Device for PXI Remote Control, with the part number 782361-01, is designed to offer seamless remote control capabilities for PXI systems. It incorporates a power control feature that automatically powers the frame on or off in sync with the host system’s power state, although manual override is possible if needed. To provide users with immediate visual feedback, the device includes six LED indicators that display the link status of the PCI Express paths.
These indicators are critical for monitoring the integrity and performance of the system. The Backplane Link Status LEDs are particularly useful for determining the PCIe link configurations with any PCIe switches located on the chassis backplane, as well as with boards inserted in any passive slots. Additionally, the Link Port Status LED gives an immediate indication of the link port’s current operational status.
Furthermore, the SMBus Controller Link Status LED is tasked with signaling the connection status between the PCIe switch and the onboard PCIe-to-PCI bridge responsible for the SMBus controller. During typical operation, this LED should emit a blinking green light at a 25% duty cycle, signifying a healthy connection. These features collectively ensure that users can reliably manage and troubleshoot their PXI systems with confidence.
