Plugins and drivers for MSFS 2020/2024 and X-Plane 11 & 12. Install the right one for your platform, then the USB serial driver that matches your hardware if you don't already have it.
MSFS
SimLink links your RHSimTech hardware to Microsoft Flight Simulator over SimConnect. Runs as a standalone executable — no in-sim add-on required.
SimLink v5.98.exe
The latest SimLink executable for use with MSFS 2020 and X-Plane 11 & 12.
MSFS network setup guide
Step-by-step guide for setting up SimConnect between two PCs using MSFS 2024 and the SimLink executable. Includes firewall configuration, a SimConnect.cfg example, and troubleshooting tips.
X-Plane
The SimLink plugin runs inside X-Plane directly and handles dataref read/write for every connected panel.
SimLinkPluginInstaller.exe
X-Plane 11 & 12 SimLink plugin. After downloading, run the installer and follow the on-screen instructions.
Legacy
No longer needed for new builds. This is only for older devices that connect to X-Plane by bridging through the MSFS version of SimLink, rather than the native X-Plane SimLink plugin above.
XPlaneConnect (SimTech).zip
Modified XPlaneConnect plugin, SimTech version. Only required if you're running a legacy device this way — new devices don't need this.
Have a legacy device still running this way? Get in touch and it can be added to the new X-Plane SimLink plugin instead, so it no longer needs the XPlaneConnect bridge.
USB serial drivers
Install the driver that matches the USB-serial chipset in your hardware. Most RHSimTech panels will already have the right driver installed on first connection — these are here in case Windows doesn't find one automatically.
CH341.zip
Driver for CH341-based USB serial adapters.
CP210x.zip
Driver for CP210x-based USB serial adapters.
Not sure which one you need?
If a panel isn't being recognised after installing the right SimLink version for your platform, check the USB serial driver first — most connection issues come down to Windows not having the matching driver for the panel's onboard chip.
Still stuck, or your device isn't recognised in beta builds? Get in touch and include which panel, which platform, and what Device Manager shows for the COM port.
