# Leica iCON iGD4

Connect a Leica iCON iGD4 machine-control display to RTK Premium corrections over NTRIP.

These steps connect a Leica iCON iGD4 machine-control display to the Premium Positioning correction network over NTRIP. They assume you already have your NTRIP credentials.

### Before you start

* Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform.
* No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=leica-icon-igd4) to get your credentials.
* The iGD4 with a working internet connection.
* No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=leica-icon-igd4#iot-sims) give it its own data connection.
* The GNSS configured on the iGD4.
* A clear view of the sky at the machine.

### Network settings

These are the same for every Premium Positioning customer. Only your username and password are unique to you.

* Server or host: rtkpremium.xyz
* Port: 2101
* Mountpoint: COMMON
* Protocol: NTRIP

### Steps

1. Open the correction profile: On the iGD4, open the device or correction profile.
2. Connect via NTRIP: Set the connection to 'Connect via NTRIP'.
3. Enter the address and port: In the NTRIP settings, enter rtkpremium.xyz as the address and 2101 as the port.
4. Enter your NTRIP username and password: Type your own credentials exactly as they appear in your welcome email. They are case-sensitive and unique to your account.
5. Set the mountpoint and network type: Enter COMMON as the mountpoint and set the network type to 'VRS'.
6. Confirm FIXED: Check that position quality reaches 'FIXED' before you start work.

### If the fix will not hold

Menu labels differ between iGD4 firmware versions, so match the nearest equivalent on your display. The display needs a live internet connection while the machine works. If position quality stays below FIXED, recheck the address, the port, the COMMON mountpoint, the network type and your credentials.
