The R2U2N1D0A2T0A is the no-OS counterpart to the Windows 10 IoT-equipped UP configurations, distinguished by the "A" suffix and the "D" storage code indicating a higher-capacity or different SSD configuration than the "C" designation. With 32 GB of soldered DDR4-2400 ECC memory and 2 PCIe slots, it is built for system integrators who deploy custom Linux builds, real-time operating systems (VxWorks 7.0 is qualified on the platform), or proprietary automation runtimes that ship as complete disk images.

Why choose a no-OS industrial PC?

No-OS configurations eliminate the Windows licensing cost and the associated update management overhead for deployments where the application stack does not require Windows. Linux-based soft PLCs, OPC UA aggregation servers, and containerized edge platforms (Docker/Podman on Yocto or Ubuntu Core) run directly on the bare-metal RXi2-UP without the resource overhead of a general-purpose desktop OS. Emerson qualifies both Windows 10 IoT LTSC and Ubuntu LTS on the UP platform, and the UEFI AMI Aptio 5 firmware supports Secure Boot for either OS path. The dual PCIe slots and 5 Ethernet ports remain identical across OS variants — only the pre-loaded software differs.
