The rover radio is intended for receiving differential corrections. The content of the dialog depends on the selected corrections type.
To configure the modem connection select either Receiver, or Controller depending on whose modem will use for communication.
You can set GSM/CDMA modem (Cellular modem) or UHF modem (Radio). The dialog content depends on the modem model selected.
To configure the radio modem:
For Internal Radio, External Radio, External Cellular specify the Baud rate for the Port to which the radio is connected.
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.
