Router Mode (Offline Setup)
Run SimVS over a local network when your tablets can't get internet access in the lab.
Most labs should use the standard setup in Network Setup and Device Pairing. Use Router Mode only if your tablets can't get internet access where you run simulations. In Router Mode, tablets talk to each other directly over a local network instead of through the SimVS cloud server.
Connect to the internet once first
Each tablet must connect to the internet at least once to validate its license. After that, you can use Router Mode without internet. The easiest time is during setup, while you install the app and sign in.
What You Give Up
| Server Mode (standard) | Router Mode | |
|---|---|---|
| Internet required | Yes | Only once, to validate each license |
| Automatic reconnection | Yes | Yes |
| Automatic updates | Yes | No |
| SimVS Portal sync | Yes | No |
You can switch back to Server Mode at any time, even mid-session. We recommend switching back whenever internet is available so tablets get updates and Portal content.
Network Requirements
- All instructor and student tablets must be on the same local network.
- Any local network works. If your package includes a SimVS router, it gives you a ready-made one.
Institutional networks
Campus and hospital networks sometimes block tablets from talking to each other. If tablets on your institution's network won't connect in Router Mode, use the SimVS router, or contact SimVS at info@simvs.com or 518-902-6156 to discuss your network.
