## How to set up Firescope on a new computer

When using Firescope on a new computer, you’ll need to configure it just like your previous setup to ensure everything runs smoothly. Use the checklist below to confirm everything is set up correctly.

## USB-Connected Roasting Machines

1. Connect Your Roasting Machine
   * In the roasting machine list, select the machine you want to use. This will initiate the connection process.
2. Check the Serial Port
   * Make sure the roasting machine is assigned to the correct serial port. You can adjust this in the machine settings.
3. If You Don’t See the Serial Port
   * Install the correct USB driver for your operating system and machine, then check the serial port list again.

4. If the Port Still Doesn’t Appear
   * Open your system’s Device Manager and check if the serial port is recognized.\

5. If It Still Doesn’t Work
   * Try connecting the machine on a different computer:
     * If it works elsewhere, the issue is likely with your new computer’s configuration.
     * If it doesn’t work on any device, there may be a hardware issue with the roasting machine, USB cable, or hub. Try replacing each component.
     * If none of these work, contact the machine manufacturer for support.

## Roasting Machines Connected via LAN or Router

1. Check Network Setup
   * Make sure your router and Wi-Fi are configured properly.
2. For Machines Like Probat which display their IP address—confirm the IP hasn’t changed.
   * If it has, update the IP address in Firescope’s machine settings.
3. For Machines Like Giesen which require manual network configuration.
   * Make sure that setup is completed beforehand.
4. Still Not Connecting?
   * Test the connection on a different computer:
     * If it works there, the issue may be local to your main device.
     * If it doesn’t work anywhe![](/files/hCG6hfLiEmukoOQHqplS)re, the problem likely lies with the machine. Please contact the manufacturer for support.
