4 User Interface
CR-105 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.
4.1 Protocol
CR-105 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.
4.2 NMEA Protocol
CR-105 is capable of supporting following NMEA formats:
NMEA RECORD Description
GGA GPS fix data
GLL Geographic
GSA GNSS DOP and active satellite
GSV GNSS Satellites in view
RMC Recommended minimum specific GNSS data
VTG Course Over Ground and Ground Speed
ZDA Time&Data
