# RX CONFIG tab

The tab **RX CONFIG** allows you to configure the RX's behavior on the field network. It is divided into two sections: **General** and **Admin**.

## Sub-tab: General

This section is dedicated to configuring the communication **BACnet** of the receiver. This is where you define the rules that will allow your supervisor (PLC, BMS) to query the gateway.

### **Serial Link Settings (BACnet MS/TP)**

<table data-header-hidden><thead><tr><th width="207.23046875">Field</th><th>Description</th></tr></thead><tbody><tr><td><strong>Speed (Baud rate)</strong></td><td>RS485 link speed (e.g. 9600, 38400, 57600, 115200 baud).</td></tr><tr><td><strong>Data bits</strong></td><td>Fixed at 8 bits.</td></tr><tr><td><strong>Stop bits</strong></td><td>Fixed at 1 bit.</td></tr><tr><td><strong>Parity</strong></td><td>None</td></tr></tbody></table>

### **Network Layer Configuration**

* **Device Mode** / **Object Mode** :
  * **Mode** **Device** : Each transmitter appears as a separate device on the network.
  * **Mode** **Object** : The receiver is the only visible device, transmitters are integrated as lists of internal objects (makes discovery easier on large networks).
* **Protocol** : Transport mode selection: **MS/TP**, **IP**, or **MS/TP + IP** (Hybrid).
* **DHCP** (Toggle): **Enable** or **disable** automatic IP assignment.
* **IP** / **Mask** / **Gateway** : Standard configuration of the Ethernet segment.
* &#x20;**UDP Port:** port number default: 47808 / 0xBAC0.

### **BACnet Settings**

This section defines the receiver's unique digital identity and that of its sensors within the BACnet tree, thereby ensuring their interoperability and automatic discovery by the building controller.

<table data-header-hidden><thead><tr><th width="194.98046875"></th><th></th></tr></thead><tbody><tr><td><strong>Network</strong></td><td>Number of the physical BACnet network where the receiver appears.</td></tr><tr><td><strong>Virtual Network</strong></td><td>Number of the virtual network dedicated to displaying wireless transmitters.</td></tr><tr><td><strong>Device ID</strong></td><td>Unique instance ID of the receiver across the entire BACnet network.</td></tr><tr><td><strong>TX Base ID</strong></td><td>Starting instance used to automatically increment sensor IDs (e.g. if Base = 1000, TX 1 will be instance 1001).</td></tr><tr><td><strong>MSTP/MAC Address</strong></td><td>Unique MAC address (0 to 127) on the RS485/IP segment to identify the physical node.</td></tr></tbody></table>

### Validation of changes

All changes made in the RX CONFIG tab are not applied instantly to avoid any accidental disconnection during data entry.

**Button** **Save** : Once your settings are entered, click the "Save" button at the bottom of the page.

{% hint style="warning" %}
The **validation** of the changes will require a **restart** of the **RX.**
{% endhint %}

## Sub-tab: Admin

The Admin sub-tab brings together critical maintenance, access security, and system update functions.

### Password configuration

This section allows access to the configuration interface to be restricted.

* Password configuration:
  * **New** : Enter your new administrator password.
  * **Confirm** : Re-enter the password to avoid any typing error.
* **Log out** : This button immediately closes the current user session.
* **Reboot** : Triggers an immediate hardware restart of the receiver.

{% hint style="warning" %}
**Warning** : The **restart** is carried out in **10 seconds** without any prior confirmation request. Make sure no Modbus network read/write operation is in progress.
{% endhint %}

### **Firmware Update**

To ensure performance and benefit from the latest Enless Wireless features, you can update the device's internal software.

* **Version** of current firmware: Displays the software version currently installed on your gateway.
* **Product type** : Select the relevant hardware from the drop-down list:
  * **`RX Receiver`** : For the main gateway.
  * **`RX Repeater`** : If you are configuring a range extension device.
* To update the *firmware* :
  1. Click the **file selection**.
  2. Choose the binary file provided by Enless support.
  3. Click **Update** to start the process.

{% hint style="danger" %}
An **update** *firmware* will require a **restart** restart of the RX. Make sure not to unplug it during the procedure.

**Before** proceeding with the **update**, please **export** your configuration csv file from the **TX Config** page using the **Export csv** button and re-import it afterward if needed.

Make sure to use the **correct type** of file ***firmware*** to update your receiver or risk**damaging** your product. For example, the *firmware* of the **RX MODBUS** is not **compatible** with an **RX BACNET**, and vice versa.
{% endhint %}

{% hint style="info" %}
If you encounter **display issues** after the update, we invite you to **clear the cache** of your browser.
{% endhint %}

### **Parameter validation**

Unlike the General sub-tab, changes made here (such as changing the password) are applied differently:

* Button **Save** : By clicking this button, the new settings are saved and applied immediately.
* **No restart required** : Applying Admin settings does not require a restart cycle to take effect (except when the "Reboot" button is explicitly used).

# 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-bacnet/configuration/rx-config-tab.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.
