# FJDynamics AT2 / AT1 autosteer

These steps connect a FJDynamics AT2 / AT1 autosteer to the Premium Positioning correction network over NTRIP, using FJD autosteer display / FJD app. 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 on the customer portal.
* FJD autosteer display / FJD app.
* A working internet connection on the controller or phone.
* A clear view of the sky at the point you are measuring.

### 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. Power up and sign in to the FJD display: Start the FJD autosteer terminal and log in with your FJDynamics account. The home screen shows status icons across the top: 4G/mobile signal, GNSS, and the correction-source (RTK) signal. Note: your FJD account login is separate from the NTRIP login you'll enter later.
2. Make sure the display has a working data connection: Network RTK comes over the internet, so the terminal needs live mobile data. Confirm the 4G / mobile-signal icon is active (insert/activate the SIM, or connect Wi-Fi if supported). Without data, it reaches satellites but never goes to RTK Fixed.
3. Open the correction-source / RTK settings: Tap the RTK / correction-source icon in the status bar (or open it from settings). FJD offers three sources: Mobile Base Station (radio), Network RTK, and SBAS. Wording/icons vary slightly by firmware - look for the RTK or correction-source setup screen.
4. Choose Network RTK: The kit defaults to Mobile Base Station. Switch to 'Network RTK' (the internet/NTRIP mode for a CORS/NTRIP service) using the selector on the right. Do not select Mobile Base Station (radio) or SBAS. Once selected, Network RTK becomes the default next login.
5. Enable Network RTK and open the connection dialog: With Network RTK selected, enable it and tap 'Connect'. The 'Connect Network RTK' dialog appears with the NTRIP server (domain) and your NTRIP account.
6. Enter the caster Host and Port: Host: rtkpremium.xyz Port: 2101. The same for every customer. Type them exactly, no 'http\://', no spaces.
7. Tap 'Get Source' to load the mountpoint list: After Host and Port, tap 'Get Source'. The terminal pulls the source table and populates 'Source Node', auto-selecting the strongest match. 'Get Source' must succeed before you can connect - if it fails, recheck Host/Port and your data signal.
8. Set the Source Node (mountpoint) to COMMON: In 'Source Node', make sure COMMON is selected; if it auto-filled a different node, tap the field and pick COMMON. The protocol is standard NTRIP - selecting Network RTK with a valid source node is what tells the kit to use NTRIP.
9. Enter YOUR NTRIP username and password: In 'Account' enter YOUR NTRIP username, and in 'Password' your NTRIP password - the per-user credentials from your welcome email. Unique to your account; don't reuse your FJD app login here.
10. Tap 'Connect': With Host, Port, Source Node (COMMON), Account and Password filled, tap 'Connect'. Allow up to \~3 minutes for the first connection to establish and converge.
11. Confirm an RTK / Fixed solution: On the home screen the RTK signal bars should be full, 'RTK' shows in the upper-right (Network RTK mode), and in Real-time Status the RTK Status value reads 4 (Fixed). Then you can create guidance lines and autosteer.
12. If it won't connect or won't reach Fixed: Recheck: Host (rtkpremium.xyz) and Port (2101) typed exactly; Source Node is COMMON; your Account/Password match the welcome email (a wrong password is the most common cause); the 4G/data signal is present; and you have clear, open sky. FJD's Troubleshooting checklist flags weak 4G or an invalid NTRIP account as the usual culprits.

### If the fix will not hold

Your NTRIP username/password come from your welcome email and are NOT your FJDynamics app login. The terminal needs live mobile-data (4G/SIM) or Wi-Fi for Network RTK. On-screen labels ('Network RTK', 'Get Source', 'Source Node', 'Account', 'RTK Status') are from current FJD AT2/AT1 manuals; menu names/icons vary by firmware - match the equivalent correction-source / RTK / NTRIP setting.
