# Getting Started

## Install the Module

**Step 1:** Make sure the radio is turned off.

**Step 2:**  Insert the MULTI-Module into the module bay of your radio, taking care that the pins line up correctly.

## Configure a Model

Once the MULTI-Module is installed in the radio you need to configure a model to use it.  Serial Mode and PPM Mode are configured differently.

### Serial Mode

In Serial Mode the radio's user interface is used to select the protocol and configure any protocol settings.

{% hint style="success" %}
If your MULTI-Module has a 16-position rotary selector, ensure the module is in Serial Mode by setting the selector is set to **0**.
{% endhint %}

**Step 1:**  Set the rotary switch to **0** and turn the radio on .

**Step 2:**  Select an existing model or create a new one.

**Step 3:**  On the Model Setup page scroll to **External RF** (or **Internal RF**, if using an internal MULTI-Module) and set the **Mode** to **MULTI**.

{% hint style="info" %}
The **Module Status** line should update to show the module's firmware version within a few seconds of the Mode being set to MULTI.  If it doesn't, check that the module is installed correctly.
{% endhint %}

**Step 4:**  Select a protocol by clicking on the field to the right of 'MULTI' ('FlySky' in the image above) and scrolling through the list to find the desired protocol.

**Step 5:**  Select the sub-protocol, if needed, by clicking on the sub-protocol field ('Std' in the image above) and scrolling through the options.  Not all protocols have sub-protocols.

**Step 6:**  Configure the additional protocol settings, as needed.  

* **RF Freq. Tuning** specifies the frequency fine tuning value
* **Receiver No.** enables Receiver Match
* **Bind on Channel** enables initiating bind use a channel input and disables bind at power on
* **Disable Telemetry** disables telemetry for this model
* **Disable Ch. map** prevents the MULTI-Module re-mapping channels to match the protocol
* **Low power mode** reduces the RF output to approximately 1/10th normal power

All the protocol options are explained in the next section, Protocol Options, with more information in each protocol-specific page.  Frequency Tuning is explained on the [Frequency Tuning page](/using-the-module/frequency-tuning.md).

{% hint style="danger" %}
If **RF Freq. Tuning** is an available setting, the [Frequency Tuning](/using-the-module/frequency-tuning.md) process **must** be completed for this protocol.
{% endhint %}

**Step 7:**  Bind the MULTI-Module to the model.  See the Binding page for more information.

### PPM Mode

In PPM Mode the 16-position rotary selector is used to select the protocol.

{% hint style="danger" %}
The radio must be off when the protocol is selected or changed.
{% endhint %}

**Step 1:**  With the radio off, select the desired protocol by setting the 16-position selector to the corresponding value.  

{% hint style="info" %}
If protocol banks are enabled, the desired bank must also be selected.  See the[ PPM Mode page](/using-the-module/ppm-mode.md#protocol-bank-selection) for more details.
{% endhint %}

**Step 2:**  Turn the radio on.

**Step 3:**  Select an existing model or create a new one.

**Step 4:**  On the Model Setup page scroll to **External RF** and set the **Mode** to **PPM**.

**Step 5:**  Bind the MULTI-Module to the model.  See the Binding page for more information.
