### For Remote Control

* **TCP Port**: 8317

## Configuring the Windows Firewall:

**1. Open Windows Defender Firewall:**

* **Windows 10**: Type "Windows Defender Firewall" in the Start menu search bar and select "Windows Defender Firewall with Advanced Security."
* **Windows 11**: Search for "Firewall & network protection" in the Start menu and click on it.

**2. Create a New Inbound and Outbound Rule:**

* **Inbound Rule**:
  * In the Windows Defender Firewall with Advanced Security window, click on "Inbound Rules" on the left-hand side.
  * Click on "New Rule..." on the right-hand side.
  * Select "Program" and click "Next."
  * Browse and select the executable file `C:\ProgramFiles\VIOSO6\SPCalibrator64.exe`, then click "Next."
  * Choose "Allow the connection" and click "Next."
  * Apply the rule to all network types ( Domain, Private, Public).
  * Enter a name and optional description for the rule, then click "Finish."
* **Outbound Rule**:
  * Follow the same steps as above, but choose "Outbound Rules" instead of "Inbound Rules."
