# How to Connect Trimble to SmartFix

This guide explains how to configure a Trimble controller running Trimble Access (such as the TSC3, TSC7, or T10) to receive RTK corrections from the SmartFix network.

---

#### 1. Creating the GNSS Contact (Internet Connection)

Before selecting your survey style, you must establish how the controller connects to the SmartFix servers via the internet.

1. From the Trimble Access main menu, select **Settings**.
   
   ![Trimble\_Settings](https://knowledgebase.globalsurvey.co.nz/hs-fs/hubfs/Trimble_Settings.png?width=400&height=295&name=Trimble_Settings.png)
2. Select **Connect**.
   
   ![Connect-1](https://knowledgebase.globalsurvey.co.nz/hs-fs/hubfs/Connect-1.png?width=400&height=255&name=Connect-1.png)
3. Select **GNSS Contacts**.
   
   ![Gnss-1](https://knowledgebase.globalsurvey.co.nz/hs-fs/hubfs/Gnss-1.png?width=400&height=230&name=Gnss-1.png)
4. Select **New** to create a contact, or select an existing one and choose **Edit** / **Copy**.
   
   ![Gnss\_Contact](https://knowledgebase.globalsurvey.co.nz/hs-fs/hubfs/Gnss_Contact.png?width=400&height=255&name=Gnss_Contact.png)
5. Check the box for **Use NTRIP**.
   
   ![NTRIP-1](https://knowledgebase.globalsurvey.co.nz/hs-fs/hubfs/NTRIP-1.png?width=400&height=253&name=NTRIP-1.png)
6. Configure the critical SmartFix server details:
   
     - **NTRIP username:** Enter your SmartFix User ID.
     - **NTRIP password:** Enter your SmartFix Password *(Case Sensitive)*.
     - **IP Address:** Enter `www.smartfix.co.nz` *(or `60.234.42.123`)*.
     - **IP Port:** Enter the port for your region (e.g., `4819` for Auckland Fixed). Refer to the [Connection Parameters](https://knowledgebase.globalsurvey.co.nz/../01_getting_started/smartfix_connection_parameters.md?hsLang=en) table.
       
       ![Ntrip\_2](https://knowledgebase.globalsurvey.co.nz/hs-fs/hubfs/Ntrip_2.png?width=400&height=253&name=Ntrip_2.png)``
7. Press **Store** to save the GNSS Contact.

---

#### 2. Configuring the Survey Style

Now you need to tell your Survey Style to use the GNSS Contact you just created, and specify the format of the corrections.

1. Return to the **Settings** menu and select **Survey Styles**.
   
   ![Styles-1](https://knowledgebase.globalsurvey.co.nz/hs-fs/hubfs/Styles-1.png?width=400&height=262&name=Styles-1.png)
2. Select **New** to create a style (e.g., `SmartFix Network`), or edit an existing RTK style.
   
   ![New\_Style](https://knowledgebase.globalsurvey.co.nz/hs-fs/hubfs/New_Style.png?width=400&height=299&name=New_Style.png)``
3. Select **Rover Options**.
   
   ![Rover\_Options](https://knowledgebase.globalsurvey.co.nz/hs-fs/hubfs/Rover_Options.png?width=400&height=252&name=Rover_Options.png)``
4. Configure the RTK settings based on your chosen port: 
     - **Survey Type:** Select **RTK**.
     - **Broadcast format:** 
           - If using a **Fixed (Network)** port (e.g., `4819`), select **VRS (RTCM)**.
           - If using a **Single Base** port (e.g., `4809`), select **Multi station (RTCM)**.
             
             ![Survey\_Type](https://knowledgebase.globalsurvey.co.nz/hs-fs/hubfs/Survey_Type.png?width=400&height=254&name=Survey_Type.png)``
5. Enter your standard Rover antenna details and press **Accept**.
6. Next, select **Rover data link** from the Survey Style menu.
   
   ![rover\_data](https://knowledgebase.globalsurvey.co.nz/hs-fs/hubfs/rover_data.png?width=400&height=250&name=rover_data.png)``
7. Configure the link to use the internet: 
     - **Type:** Select **Internet connection**.
     - **GNSS Contact:** Select the SmartFix contact you created in Section 1.
       
       ![smartfix\_net](https://knowledgebase.globalsurvey.co.nz/hs-fs/hubfs/smartfix_net.png?width=400&height=258&name=smartfix_net.png)``
8. Press **Accept** and then **Store** the Survey Style.

#### 3. Starting the Survey & Selecting a Mountpoint

1. From the main menu, select **General Survey** (or your preferred survey module).
   
   ![General\_Survey](https://knowledgebase.globalsurvey.co.nz/hs-fs/hubfs/General_Survey.png?width=400&height=288&name=General_Survey.png)
2. Select **Measure** and choose your new `SmartFix Network` Survey Style.
   
   ![General\_Survey\_Smartfix](https://knowledgebase.globalsurvey.co.nz/hs-fs/hubfs/General_Survey_Smartfix.png?width=400&height=250&name=General_Survey_Smartfix.png)
3. Select **Measure points** (or Continuous Topo) to initialise the connection.
4. Because you are connecting to an NTRIP server, Trimble Access will download the "Source Table" and display a list of available mountpoints. 
     - Select the required mountpoint for your area (e.g., `AUCKfixedADV4`).
       
       ![Mountpoint-1](https://knowledgebase.globalsurvey.co.nz/hs-fs/hubfs/Mountpoint-1.png?width=400&height=352&name=Mountpoint-1.png)``
5. Press **Enter**. Your rover will dial out, receive corrections, and initialise.
