# Connecting to an External Controller

In order to cover applications where a physical controller is required, the STRwrench can connect to Power Focus 8, Power Focus 6000, STpad or STpalm.

Applications where this is required can be, for example:

- when using field bus

- when using wired station accessories (stack light, operator panel, and so on)

- when using I/O

- when a controller is needed as a physical hub and buffer

1. Go to Integrated Controller Tool in the home menu and select Integrated Controller in the left pane.

2. Set Integrated Controller to Off in order to connect the STRwrench to the external controller. Wait for the tool to restart.

   When the Integrated Controller is disabled, the STRwrench Web User Interface shows a reduced version of the menu, consisting of three tabs: Configurations, Tool Management and Settings.

3. In Settings, select STRwrench Connect > Tightening Manager and select the external controller you wish to connect the STRwrench to:

   - Power Focus to connect the STRwrench to Power Focus 8 or Power Focus 6000.

   - QA Inspector to connect the STRwrench to STpad or STpalm.

4. Select the type of connection you wish to establish between the STRwrench and the selected external controller:

   - Bluetooth.

   - Wi-Fi.

     If you select a Wi-Fi connection to Power Focus, two additional parameters will be displayed:

     - Server Port: This parameter is not editable.

     - Server host: Enter the IP address of your Power Focus.

     If you select a Wi-Fi connection to QA Inspector, one additional parameter will be displayed:

     - Server Port: This parameter is not editable.

   Select Apply and wait for the STRwrench to reboot.

5. In the external controller, the STRwrench will now show up in the dedicated menu section.

   For further configurations in the external controller, respectively refer to Power Focus 8 User Guide, Power Focus 6000 User Guide, STpad Configuration Manual or STpalm Configuration Manual.
