# Input Device Configuration Panels

Each of the input devices has its tab on the main window. The Figure below shows a closeup of the expanded view of the main window. The tabs are similar; the DVL tab includes an option for Ethernet connectivity. The tabs feature the following types of controls:

* Input port selection:
  * No device attached. This will turn off serial or Ethernet searching for this device. It is not strictly necessary, but the search process update messages may be distracting to you.
  * Search Ethernet (DVL only). CeruleanTracker will send Ethernet discovery requests periodically until the DVL is found on the network. If the DVL is found, and later disconnected (e.g., powered off) CeruleanTracker will resume sending discovery requests.
  * Search this PC’s Serial Ports. CeruleanTracker will check each active serial port on the PC in turn, and if it can, will open the port at different baud rates and listen for a few seconds. If it receives a message appropriate to the device it is looking for, it will keep the port and attempt to carry on. If the device is disconnected later, the search will resume.
  * Use Serial Port/Baud Rate. CeruleanTracker will attempt to connect to the specified port at the specified baud rate. If it receives a message appropriate to the device it is looking for, it will attempt to carry on. If the device is disconnected later, CeruleanTracker will try to reconnect to the specified port at the specified baud rate.
* Connection status. This shows the state of the physical connection used for communication, e.g., “Port is open”, “using Com Port X at baud rate Y”, “can’t open Com Port X”.
* Communication status. This shows the state of actual communication with the device, i.e., we are receiving messages, or timed out waiting for next message.
* Most recent communication received. The latest raw message from the device.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ceruleansonar.com/c/ceruleantracker/overview/operating-ceruleantracker/input-device-configuration-panels.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
