# Pair a Network Pro with an SCS Controller or Monitor
## Pair a Network Pro with an SCS Controller or Monitor that is already set up inside a cooler with AoFrio's Field app.
#### Before you start
Follow these steps if:
- the OEM hasn't already made the 1-to-1 association with the Network Pro during installation at their factory, OR
- if you are adding a Network Pro to a cooler with an existing SCS Controller or Monitor in the field.
---
#### 1 - Make sure you have the correct permissions and software
- You will need a [user role with permission to manage pairing](https://support.aofrio.com/enable-a-role-in-your-organization-to-use-field-app?hsLang=en) with other AoFrio hardware. This can be
granted through User Roles within AoFrio’s User Manager software.
- Your version of Field app must be version 5.28 or later. You can check the Field app version from the menu within the app and download the latest version if required.
- Your device must have an active internet connection to perform this configuration
---
#### 2 - Set up your hardware
**Network Pro**
- [Install a Network Pro ONE or MULTI in a cooler cabinet](https://support.aofrio.com/planning-where-to-install-a-network-pro-one-in-your-cooler?hsLang=en)
- Make sure the Network Pro is powered OFF
- Ensure you are in a location with a [clear cellular network signal](https://support.aofrio.com/about-cellular-iot-connectivity-for-aofrio-devices?hsLang=en)to set up and upload data to the Cloud.
**SCS Controller**
- Power ON the Controller to start.
- The SCS Controller firmware must be FW version 4020 or later. [Find the current firmware version for your SCS Controller.](https://support.aofrio.com/find-the-current-firmware-version-for-your-scs-controller?hsLang=en)
- [Setup or commission an SCS Controller using Field app](https://support.aofrio.com/add-a-cooler-with-an-scs-controller-to-your-list-on-the-field-app?hsLang=en)
**Monitor**
- [Mount a Monitor in a commercial refrigeration cabinet](https://support.aofrio.com/mount-a-monitor-in-a-commercial-refrigeration-cabinet?hsLang=en)
- Connect to the Monitor using Field app to confirm it is active and collecting data.
---
#### 3 - Pair your Network Pro
1. Go to Field app and select the SCS Controller or Monitor from the list of visible devices and click **CONNECT**.
2. Open the main menu and select **SCS SETUP**.
3. Click **EDIT** in the row for **GATEWAY ONE serial #.**
4. Either:
1. Type in the Gateway serial number, OR
2. Scan the QR code by clicking **SCAN BARCODE**.
5. Click **SAVE** to complete the configuration.
You are ready to “power up” the Network Pro. If it is already plugged in, unplug for at least 2 minutes then plug in again and “power on” for it to download the latest configuration.
#### Configuration troubleshooting
| **Error message** | **Cause** | **Possible solution** |
| --- | --- | --- |
| **Assign controller to Network Pro failed.** | The mobile device being used to do the configuration requires an internet connection. | Check if the internet connection for your mobile device is active. |
| **This feature is only available for controllers running 4020 or higher firmware version. Please first upgrade this controller.** | The firmware version is not set up to run this function. | Update the SCS Controller firmware and try again. |
| **Assignment failed. This Network Pro has the incorrect SKU for this operation.** | The Network Pro you are trying to associate is not a Network Pro ONE and can't be used in a 1-1 association. | Make sure the device is a Network Pro ONE model. Normally this is easiest by checking the outside label of the device. |
| **Assignment failed. This Network Pro belongs to a different owner than the cooler. Do you still want to assign NETWORK PRO ONE XXXXX to this controller?** | The Network Pro ONE you are trying to associate has already been claimed to another bottler, CDE company or other brand. | Click **OK** to proceed and override the association. |
| **Network Pro XXXXXX already has another controller assigned to it. Do you still want to assign XXXX to this controller?** | The Network Pro ONE appears to be tracking an SCS Controller already. | Click **OK** to proceed and override the association. |
| **This action will re-assign tracking of this cooler to a different Network Pro. Do you wish to continue?** | The SCS Controller appears to be tracked by another Network Pro ONE. | Click **OK** to proceed and override the association. |
