5. Real Time DGPS: Base Radio

The base radio is intended for transmitting differential corrections. You can set GSM/CDMA modem (Cellular modem) or UHF modem (Radio) or LongLink™ for HiPer SR/HiPer VR/HiPer HR receivers. The dialog content depends on the modem model selected.

To configure the radio modem:

  1. In the Type field select which type of Radio Modem you will use: Internal Radio, or Internal Cellular, or External Radio, or External Cellular.
  2. In the Model field select model of the modem. For HiPer SR, HiPer VR and HiPer HR receivers, the LongLink™ modem does not require any additional settings.
  3. For Internal Radio, External Radio, External Cellular specify the Baud rate for the receiver Port that the radio is connected to.

    Note: Sometimes during modem connection, for the "Auto" baud rate selection of the modem, the baud rate could not be set. The software creates an error message for this case: ”Modem baud rate could not be determined automatically. Please run TRU (see Help for details) or specify baud rate in configuration”. See here how to resolve the issue.

  4. For External Radio, External Cellular specify communication parameters for the receiver Port that the radio is connected to: Parity, the number of Data bits, the number of Stop bits, which are specific to the connected modem.
  5. If required, click Defaults to return all the communication parameters to the default settings.
  6. Click Next to specify the base and rover modem radio parameters as required.
