# Additional Connection Possibilities

There are many possibilities for interconnecting the DVL and using it to control the ROV and/or monitor the DVL passively without interfering with ROV control. Three are shown below.

![Using Both Interfaces. Serial and Ethernet interfaces can be used simultaneously for listening. We do not recommend sending commands on both interfaces. Pick one or the other.](/files/IbtGfrSIs1RJ9DiYk8t3)

![Using a Port Replicator to monitor the DVL while also using it in ROV control.](/files/XsOEEhHww4Zseu09W0uH)

![In Body Frame mode, connections are simple and an optional on-ROV GPS would provide no benefit.](/files/zefJ4o0Du4qpy6tpBnEe)
