EB-230 Data Sheet 3 User Interface EB-230 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. Additional 5-pin SPI port is provided for connection with external sensors such as compass, gyro…etc. SPI port share same pin location with general purpose input / output pins (pin #10 ~14). 3.1 Protocol EB-230 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. To achieve optimal compatibility it is intended to implement 100% compatible operating modes to existing protocols since these protocols are largely symmetrical and designed to provide a bi-directional exchange of data between GPS equipments. 3.1.1 NMEA Protocol EB-230 is capable of supporting following NMEA formats: NMEA Prefix Format Direction $GPGGA GPS fix data Out $GPGLL Geographic position Latitude / Longitude Out $GPGSA GNSS DOP and active satellites Out $GPGSV Satellites in view Out $GPRMC Recommended minimum specific GNSS data Out $GPVTG Velocity and track over ground Out $GPZDA Date and time Out 7 Ver 1.2

EB-230 Data Sheet 5 Application Information 5.1 GPS Antenna Recommendations Follow below recommendations when choosing GPS antenna for EB-230 for best system performance. Transystem also offers active antenna products for optimal performance with EB-230. For details, please contact your Transystem sales contact directly. • Use active antenna that works with 3V power supply • Receiving frequency 1575.42 ± 1.032MHz • Polarization RHCP (right hand circular polarized) • Output impedance = 50 Ohm • 15dB ≦ LNA Gain ≦ 20dB • Noise figure ≦ 2.0dB • Connector: surface mounted on main PCB, Ipex or MMCX 5.2 Application Circuit 【Note1】: GPS Status (pin#4) can be used as GPS position fix indicator. 【Note2】: V12RTC (pin#15) could connect to 1.0 ~1.5Vdc power supply directly. 【Note3】: Separate V30D (pin#3) from V30A (pin#16) for optimal performance. 14 Ver 1.2
EB-230 Data Sheet 5.3 General GPS Receiver User’s Tips • If the satellite signals can not be locked or experiencing receiving problem (while in urban area), following steps are suggested: a) Please plug the external active antenna into GPS receiver and put the antenna outdoor or on the roof of the vehicle for better receiving performance. b) Move to another open space or reposition GPS receiver toward the direction with least blockage. c) Move the GPS receiver away from the interference sources. d) Wait until the weather condition is improved. • Some vehicles having heavy metallic sun protecting coating on windshields may affect signal receptions • Driving in and around high buildings may affect signal reception. • Driving under tunnels or in buildings may affect signal reception. • In general, GPS receiver performs best in open space where it can see clean sky. Weather will affect GPS reception – rain & snow contribute to worsen sensitivity. • When GPS receiver is moving, it will take longer time to get position fix. Wait for satellite signals to be locked at a fixed point when first power-on the GPS receiver to ensure quick GPS position fix. 15 Ver 1.2

  • 7. EB-230 Data Sheet 3 User Interface EB-230 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. Additional 5-pin SPI port is provided for connection with external sensors such as compass, gyro…etc. SPI port share same pin location with general purpose input / output pins (pin #10 ~14). 3.1 Protocol EB-230 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. To achieve optimal compatibility it is intended to implement 100% compatible operating modes to existing protocols since these protocols are largely symmetrical and designed to provide a bi-directional exchange of data between GPS equipments. 3.1.1 NMEA Protocol EB-230 is capable of supporting following NMEA formats: NMEA Prefix Format Direction $GPGGA GPS fix data Out $GPGLL Geographic position Latitude / Longitude Out $GPGSA GNSS DOP and active satellites Out $GPGSV Satellites in view Out $GPRMC Recommended minimum specific GNSS data Out $GPVTG Velocity and track over ground Out $GPZDA Date and time Out 7 Ver 1.2

  • 14. EB-230 Data Sheet 5 Application Information 5.1 GPS Antenna Recommendations Follow below recommendations when choosing GPS antenna for EB-230 for best system performance. Transystem also offers active antenna products for optimal performance with EB-230. For details, please contact your Transystem sales contact directly. • Use active antenna that works with 3V power supply • Receiving frequency 1575.42 ± 1.032MHz • Polarization RHCP (right hand circular polarized) • Output impedance = 50 Ohm • 15dB ≦ LNA Gain ≦ 20dB • Noise figure ≦ 2.0dB • Connector: surface mounted on main PCB, Ipex or MMCX 5.2 Application Circuit 【Note1】: GPS Status (pin#4) can be used as GPS position fix indicator. 【Note2】: V12RTC (pin#15) could connect to 1.0 ~1.5Vdc power supply directly. 【Note3】: Separate V30D (pin#3) from V30A (pin#16) for optimal performance. 14 Ver 1.2
  • 15. EB-230 Data Sheet 5.3 General GPS Receiver User’s Tips • If the satellite signals can not be locked or experiencing receiving problem (while in urban area), following steps are suggested: a) Please plug the external active antenna into GPS receiver and put the antenna outdoor or on the roof of the vehicle for better receiving performance. b) Move to another open space or reposition GPS receiver toward the direction with least blockage. c) Move the GPS receiver away from the interference sources. d) Wait until the weather condition is improved. • Some vehicles having heavy metallic sun protecting coating on windshields may affect signal receptions • Driving in and around high buildings may affect signal reception. • Driving under tunnels or in buildings may affect signal reception. • In general, GPS receiver performs best in open space where it can see clean sky. Weather will affect GPS reception – rain & snow contribute to worsen sensitivity. • When GPS receiver is moving, it will take longer time to get position fix. Wait for satellite signals to be locked at a fixed point when first power-on the GPS receiver to ensure quick GPS position fix. 15 Ver 1.2
