# Configuring the Servo Hub with a Control Hub

{% hint style="success" %}
You must be running Robot Controller App and Driver Station App version 10.0 to use a Servo Hub.
{% endhint %}

## Setting Servo Hub IDs <a href="#accessing-the-configuration-utility" id="accessing-the-configuration-utility"></a>

{% hint style="info" %}
Servo Hub IDs should be set while the Servo Hub is disconnected from a Control Hub OR before powering the robot on. Servo Hubs previously connected to a robot may need to be power cycled before changing IDs.
{% endhint %}

By default, the Servo Hub's ID should be set to 3. This can be changed by connecting the Servo Hub directly to the REV Hardware Client using a USB-C cable. The Servo Hub will appear in the Hardware List as shown below:

The "CAN ID" is the individual ID for the Servo Hub.

{% hint style="warning" %}
Each Servo Hub and Expansion Hub must have a unique ID before being able to complete the configuration process.&#x20;
{% endhint %}

The CAN ID can be set between 1-10 for FTC. After choosing the ID, click "Set CAN ID".

{% hint style="info" %}
Expansion Hubs default to ID 1 or 2.
{% endhint %}

{% hint style="danger" %}
Pressing "**Scan**" on an existing configuration may result in the already named devices being erased. A new configuration file is needed when adding a camera or Expansion Hub over USB.
{% endhint %}

4. All connected Servo or Expansion Hubs using RS485 will appear within the menu of the portal. If you are using multiple Servo Hubs, they can be identified by their ID number.
