RS-232 serial interface specification

Applicable receivers:  All receivers

The RS-232 serial interface specification enables a remote computing device to communicate with a GNSS receiver over an RS-232 connection, using data collector format packets. The RS-232 serial interface specification provides command packets for configuring the receiver for operation, and report packets for retrieving position and status information from the receiver.

Data Collector Format packets are similar to the data collector format packets which evolved with the Trimble legacy receivers. The set of data collector format command and report packets implemented on the receiver are simplified with a more flexible method for scheduling the output of data. For a detailed explanation of the streamed data output format, refer to the Output Messages section.

The receiver can be configured using application files or single commands. Application files include fields for setting all receiver parameters and functions, and can be useful if multiple settings need to be changed or saved for a particular receiver application. The default application file for the receiver includes the factory default values. Multiple application files can be transferred to the receiver for selection with command packets. Application files for specific applications can be developed on one receiver and downloaded to a computer for transfer to other receivers. For information about the structure of application files, see Response 64h, APPFILE (Application file record report).
