### 2. Network Credentials (Quick Reference)

If you already know your device menu, here are the raw data points you need.

### 3. Universal Setup (Trimble, Leica, Topcon, etc.)

Most professional survey rovers use different names for the same settings. Use this **Translation Dictionary** to configure your device correctly.

#### Step A: Configure the NTRIP Caster

Find the menu called **"GNSS Contacts"**, **"RTK Profiles"**, or **"Internet Source"**.

| Standard Term  | Trimble / Spectra | Leica Geosystems | Topcon / Sokkia | Your Value                        |
| -------------- | ----------------- | ---------------- | --------------- | --------------------------------- |
| **IP / Host**  | IP Address / URL  | Server           | IP Address      | `rtk.rtkdata.com` (Select region) |
| **Port**       | IP Port           | Port             | Port            | `2101`                            |
| **Mountpoint** | Mountpoint        | Mountpoint       | Source          | `AUTO`                            |
| **User**       | NTRIP Username    | User ID          | User            | *(From Dashboard)*                |
| **Password**   | NTRIP Password    | Password         | Password        | *(From Dashboard)*                |

#### Step B: The "Data Format" Trap

Your rover will ask what format to expect.

* **Correct Setting:** `RTCM 3.2` (or `RTCM 3.X`, `Auto`).
* **Avoid:** `CMR`, `CMR+`, `RTCM 2.3`.

#### Step C: NMEA Output (Crucial!)

Since we use **Nearest Base** technology, you **must** send your position to the server.

* Find the setting: **"Send GGA"** or **"NMEA Output"**.
* Set it to: **ON** (or "1 second", "0.1 Hz").
* **Without GGA, the server will not send any corrections.**

### 4. Troubleshooting Common Rover Issues

**Status: "Source Table Not Found"**

* **Cause:** Your device cannot resolve the domain name (DNS issue).
* **Fix:** Try using the numeric IP address instead of the domain (e.g., use `3.73.41.96` for EU).

**Status: "Connected" but "Latency > 5s"**

* **Cause:** You are using the default Port 80, which is often throttled by mobile carriers.
* **Fix:** Change Port to **2101**.

**Status: "Float" (No Fixed Solution)**

* **Cause 1:** You are indoors or near a wall. Go to open sky.
* **Cause 2:** You manually selected a distant Mountpoint.
* **Fix:** Change Mountpoint to **`AUTO`** to force the nearest station.

{% hint style="info" %}
**Need a Config File?** For some legacy devices (Trimble TSC3, Leica CS15), we can generate a configuration file. [**Contact Support**](https://docs.rtkdata.com/support/support) with your exact controller model.
