Installing Nexus
What to install on which machine, the Windows and Linux procedures, and the first-run wizard that creates your administrator account.

Install, commission and operate the platform — Nexus, the gateway everything connects to, and the Studio, Spectrum and Lens clients.
This manual covers Raylux: the Nexus service, and the three client programs that connect to it:
| Component | What it is | Who runs it |
|---|---|---|
| Raylux Nexus | Nexus — tag engine, historian, device drivers, alarms, reporting, and the web server that serves everything else. Runs as a Windows service or a systemd unit. | Installed once per site, on a server. |
| Raylux Studio | The designer. Builds the screens, tags, alarms and reports that Nexus runs. | On an engineer's workstation. |
| Raylux Spectrum | The operator runtime, served by Nexus as a web page. Nothing to install — it is a browser. | Any machine on the plant network. |
| Raylux Lens | A desktop shell that displays Spectrum full-screen, for a panel PC with no desktop. | On plant-floor panels. |
You are reading this from Nexus itself, at /manual. It is installed alongside Nexus and works with no internet connection.
Version
This manual is built and shipped with Nexus, so it always describes the version you have installed — the badge at the top of every page names it. The running Nexus's own version shows in ConfigHub's top bar next to the gateway name (e.g. "Raylux 2026.12") once you are signed in — it is not shown to an anonymous visitor. From the command line, run raylux-nexus --version.
