# Clyr Controller RS485 Networks
## What are Clyr RS485 Networks and where do I find them?
You will see on the Clyr Controller board that there are A1, B1, A2, B2, Ain, and Bin. What are these for? Turns out they're really important.
In order to prevent situations where equipment communication may interfere, Clyr offers you the ability to separate communication networks for different pieces of equipment if you want.
As an example, our previous section introduced **Controlling vs. Monitoring. In this case, we can use Network 1 (A1/B1) in order to monitor the equipment and we can use Network 2 (A2/B2) to read data from our sensors.**
## Where will I find networks in the app and how do I set them up correctly?
You only need to worry about networks when adding or configuring the equipment in the Clyr app. It is typically found on the "Add" page under "Advanced Options".
{% hint style="info" %}
By default, Clyr Controller will add equipment to Network 1 during setup unless you configure it differently during setup.

## 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.clyrpool.com/controlling-vs.-monitoring/clyr-controller-rs485-networks.md?ask=&goal=
```
`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.
