5. User Interface

UB-93 provides 2-wire digital UART port for communication of GPS position data

using NMEA protocol or MTK extension protocol. UART port is capable of 4800 to
115200 baud rate.

5.1 NMEA Protocol

UB-93 is default to support standard NMEA-0183 protocol. In addition, a series of

MTK extensions (PMTK messages) have been developed that can be used to provide
extended capabilities common to many applications.

NMEA Protocol format

UB-93 is capable of supporting following NMEA formats:
