From Spirit System Manual
Now you are ready to power up the unit. If your Power supply is not connected yet, we recommend to connect it to the AUX1, AUX2 and/or CH0 port. Before you can utilize the CrossFire connection, it is important to set the CRSF/ELRS receiver type at the General tab of the software. Please start the Spirit Settings and change the receiver type as displayed on the photo. Then save the settings (e.g. by CTRL+S) or the Backup tab/Unit - Save and restart the unit.
