 ## Configure the Gateway
 
-### Before configure your LoRa gateway
+### Define your MODEL
+
+In case that your LoRa concentrator is a ```RAK2287```, it's important to change the Device Variable with the correct ```MODEL```. The default ```MODEL``` on the balena Application is the ```RAK2245```.
+
+1. Go to balenaCloud dashboard and get into your LoRa gateway device site.
+2. Click "Device Variables" button on the left menu and change the ```MODEL``` variable to ```RAK2287```.
+
+That enables a fleet of LoRa gateways with both ```RAK2245``` and ```RAK2287``` together under the same app.
+
+
+### Get the EUI of the LoRa Gateway
 
 The LoRa gateways are manufactured with a unique 64 bits (8 bytes) identifier, called EUI, which can be used to register the gateway on The Things Network. To get the EUI from your board it’s important to know the Ethernet MAC address of it. The TTN EUI will be the Ethernet mac address (6 bytes), which is unique, expanded with 2 more bytes (FFFE). This is a standard way to increment the MAC address from 6 to 8 bytes.
