To configure a rover radio data link

To obtain GNSS corrections at the rover using a radio data link, you can connect the Trimble Access software to a Trimble GNSS receiver that has an internal radio or to an external radio.

To configure the connection to a radio data link at the base, see To configure a base radio data link.

  1. Connect the controller to the receiver using Bluetooth or a cable.
  2. Tap and select Settings / Survey styles. Select the required survey style. Tap Edit.

  3. Select Rover data link.

  4. Set the Type field to Radio.

  5. In the Radio field, select the type of radio you are using. Select Receiver internal or EMPOWER RTK Radio.

  6. To connect to and configure the internal settings of the radio you have selected, tap Connect.

    1. If the radio is a dual-band radio, select the frequency Band to use.

    2. If the radio is receive-only, you may be able to change the country of operation. If this setting is available, set it to the country or region you are operating in to change the available frequencies available.

      In most cases the Country is pre-set and you cannot change this setting.

    3. Select the radio Frequency to use.

      To add a new receive frequency for the rover radio, tap Add Frq. Enter the new frequency and tap Add. The new frequency is sent to the radio and appears in the list of available frequencies. To use the new frequency, you must select the frequency from the list.

    4. Select the Radio mode.

  7. Tap Accept.

    The radio signals icon appears in the status bar when a survey is started.

    If there is a problem with the data link between the base and rover receivers, a red cross is drawn over the radio signals icon .

When connected to the radio, you can tap the radio signals icon in the status bar to review the radio configuration and change the radio's internal settings, if required.

  1. Connect the controller, receiver, radio and, if required, the power supply. See To connect an external radio to the GNSS receiver.

    Some TRIMTALK and Pacific Crest radios must be in command mode before they can be configured. Command mode happens momentarily at power up. Follow the prompts to connect to the radio.

  2. Tap and select Settings / Survey styles. Select the required survey style. Tap Edit.

  3. Select Rover data link.

  4. Set the Type field to Radio.

  5. Set the Radio field to the radio type you are using and if required, select the Port on the radio you are using for the connection.

  6. If your radio does not appear in the Radio list, select Custom radio and then define the receiver port, baud rate, and parity.

  7. If the radio is connected:

    • directly to the receiver, clear the Route through controller check box. Specify the receiver port number that the radio is connected to, and the baud rate for communications.
    • to the controller, select the Route through controller check box. This enables real‑time data between the receiver and the radio to pass through the controller. Specify the controller port number that the radio is connected to, and the baud rate for communications.

  8. To connect to and configure the internal settings of the radio you have selected, tap Connect.

    1. Select the radio Frequency to use.

      To add a new receive frequency for the rover radio, tap Add Frq. Enter the new frequency and tap Add. The new frequency is sent to the radio and appears in the list of available frequencies. To use the new frequency, you must select the frequency from the list.

    2. Select the Radio mode.

  9. Tap Accept.

    The radio signals icon appears in the status bar when a survey is started.

    If there is a problem with the data link between the base and rover receivers, a red cross is drawn over the radio signals icon .

When connected to the radio, you can tap the radio signals icon in the status bar to review the radio configuration and change the radio's internal settings, if required.
