# Typical Configuration

![This diagram shows a typical interconnection for CeruleanTracker for a BlueROV2 system. As noted elsewhere, one or the other of the DVL or ROVL might not be present. A variation is to connect the DVL to the Companion RPi by serial and forward the serial data through the tether, eliminating the ROV Ethernet switch.](https://2098770382-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FJmHibmWKSWDSTSNZwtIB%2Fuploads%2F5i3aDyJC6nEp77MNNDtn%2F2?alt=media)
