3.4.2Serial Data Interface

The receiver includes two COM ports (COM1 and COM2). Both COM ports operate independently with data transfer rates adjustable from 300 to 19200 bps.

COM1 supports data input (for receiver configuration and control) and output (for example, navigation results and receiver status). COM2 only supports data output if your SUPERSTAR II is a BASE model. This model also supports data input (roving unit mode) or output (optional base station mode) for differential correction data adhering to Reference [2] on Page 13.

Your receiver must be a BASE model to act as a base station. A list of models is in Appendix A of the L1 GPS Firmware Reference Manual and in our Price List available from the Sales side menu of our website at www.novatel.com.

COM1 and COM2 support communication using the binary protocol. Through specific binary messages, the ports are re-configurable to communicate with NovAtel’s PC-based user-interface StarView software (for extensive monitoring of SV tracking, measurements and navigation status).

The default data transfer rate is 9600 bps but can be reconfigured (refer to Message ID# 110, Configure COM1 Port Mode in the L1 GPS Firmware Reference Manual). The new configuration is stored in NVM. If no default message list has been stored in NVM, the receiver will output Message ID# 20, Navigation Data (refer to the L1 GPS Firmware Reference Manual) at a rate of once per second after each power up.

COM1 can be used for S/W reprogramming (please see Appendix F, Updating Receiver Firmware, starting on Page 64).

See also Section A.2.3 on Page 48 for the electrical characteristics and the Input/Output Message rows on Page 45 for COM port details.

The default data transfer rate is 9600 bps unless your receiver model has Carrier Phase Output (CP) capability in which case it may be 19200. A list of models is in Appendix A of the L1 GPS Firmware Reference Manual and in our Price List available from the Sales side menu of our website at www.novatel.com.
