<details open>

<summary><strong>What is the receiver's power consumption?</strong></summary>

Consumption is normally less than 50 mA at 12V. During the sensor installation phase, there may be peaks of up to 500 mA.

To avoid any issues, please maintain 1A 12V on the power terminal block.

<summary><strong>What is the maximum number of simultaneous TCP clients?</strong></summary>

The Enless receiver behaves like a server and can only accept one client at a time. Being queried by another Modbus device may disrupt Modbus communication with the current TCP client.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://enless.gitbook.io/centre-aide/guides-installation/documentation-en/products/rx-modbus/troubleshooting.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.
