PXE-Boot nPC20 Thin Client Hardware

High Performance, Compact, Thin Client Node

The nPC20 Fanless Node Thin Client is a high-performance, non-display computer built for industrial use. Intel® ATOM Dual Core processing options give this industrial-grade node the power to run your control applications. With quality and durability in mind, the nPC20 is built to be reliable in the most extreme conditions and is fully tested with UL Class I, Div 2 certifications. The nPC20 will also offer several mounting options including DIN-Rail and mounting brackets, making mounting in a NEMA enclosure much simpler.

Note: This PXE-boot configuration does NOT contain any storage or operating system. It is configured for booting to a network via the Preboot eXecution Environment (PXE) protocol only. It is NOT a standalone PC. This configuration can be used for booting to a multitude of other Thin Client applications (other than ThinManager) using the PXE protocol. This has also been verified to be ThinManager XLi compatible. Comark does not supply Thin Client software applications. Consult the Thin Client application software developer for support.
