If you are using DigiTerra Explorer on Trimble devices the GNSS settings tab appears with basically different controls. The GNSS settings tab has two modes: I.Trimble Pathfinder Tools based (SiRF or TSIP) and II. NMEA. The default is the first one. These GPS port reading modes can be switched on the GNSS Status panel with the button in the bottom right corner on Trimble devices only.

PP base distance: base distance for postprocessing. Default value is less than 25 km. Use this property to set or obtain the estimated distance to the base station that will be used during postprocessing. If you will use more than one base station (during H-Star processing), specify the estimated distance to the closest base station.
SSF file: Starts writing into an SSF file for postprocessing when the GPS active. Displays only on Trimble devices. The SSF file can be postprocessed with Trimble Pathfinder Office desktop software.
