# Getting started

One or more sensors remain out of range of the LoRa Easy receiver. Install a repeater then.

{% hint style="success" %}
The repeater requires no configuration.
{% endhint %}

{% stepper %}
{% step %}

### Position the repeater

Place the repeater halfway between the sensors and the LoRa Easy receiver.

Avoid nearby metal obstacles. Keep the antenna clear.

The repeater comes with a quarter-wave antenna. Use a long-range antenna if necessary.

You can chain multiple repeaters to cover several distant areas.

For mechanical details, see [Mounting](/centre-aide/guides-installation/documentation-en/products/rx-repeater/installation/mounting.md).
{% endstep %}

{% step %}

### Power the repeater

Once the repeater is positioned, connect its power supply.

The repeater can be powered:

* by a 12 V power supply unit supplied separately by Enless
* by a main power supply of 7.5 to 24 VDC

{% hint style="warning" %}
Disconnect the power before wiring. Check the polarity before powering on.
{% endhint %}

Connect the wires to the terminal block **POWER** :

* wire **black** to **0V**
* wire **red** to **V+**

{% hint style="info" %}
At 12 VDC, the maximum current is 1 A. Use only a CE-certified 12 V power supply.
{% endhint %}

For electrical details, see [Power supply](/centre-aide/guides-installation/documentation-en/products/rx-repeater/installation/power-supply.md).
{% endstep %}

{% step %}

### Check operation

The RX REPEATER has 3 LEDs on the circuit board. It also has an external LED on the lower part of the housing.

#### Internal LEDs

#### External LED

{% hint style="info" %}
On the configuration server, frames that pass through a repeater display **(R)** next to the RSSI value.
{% endhint %}
{% endstep %}
{% endstepper %}

### Demonstration

See below the (R) in the RSSI column

{% hint style="warning" %}
It is strongly recommended to use only one repeater per receiver.
{% endhint %}

## 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-repeater/installation/getting-started.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.
