Block Diagram
Sony provides all necessary components for GPS location estimations with the GXB5210 module.
The only other requirements are voltage and RS232 receiving capability to capture the position outputs.
The module is small and compact to fit into most applications. For the best results, the module should be
placed with the antenna faced towards open sky to capture as much visible satellites as possible.

NMEA-0183 Format
The GXB5210 can output 8 different types of sentence: GPGGA, GPGLL, GPGSA, GPGSV, GPRMC, GPVTG,
GPZDA and PSGSA. If 9600bps or 19200bps or 38400bps baud rate is set for port setting, it outputs 7 types
of sentence: GPGGA, GPGSA, GPGSV, GPRMC, GPVTG, GPZDA, PSGSA as default. Moreover, if 4800bps
baud rate is set, it outputs 4 types of sentences: GPGGA, GPGSA, GPGSV, GPRMC as default.

Initialization
The GXB5210 has a reset pin (Pin 6) and normally this pin should be left open. The GXB5210 can perform the
power-on reset operation only by turning on or off the power supply pin (Pin 8). In addition, when configuring
the component in order to realize the reset from the system side during operation, connect the reset pin to the
external circuit. The following setting enables the reset.
1. When turning the power on (Power-on reset)
When applying the power supply to the power supply pin (Pin 8), set the reset pin (Pin 6) Low in advance, and
set it High 100ms after power-on.
2. Initialization during operation
When performing the reset while the reset pin (Pin 6) is High, keep it Low for 100
s or more before setting High.
NMEA Message Output Timing
NMEA messages are output within 1s after the 1PPS pulse.

1PPS Output
The 1PPS output provides a timing pulse synchronized to GPS time once a valid fix is available.
The figure below shows the behavior of the 1PPS output signal after reset. For a period of 160
s after reset,
the 1PPS signal outputs the system clock. The actual 1PPS signal is activated at 500ms after reset.
CPU clock exists for 160s after reset
1PPS signal output occurs 500ms after reset

Backup Mode
The backup mode is established by setting all inputs Low except for B.U. (Vbat: 2.6 to 3.0V). In this mode, the
low power consumption can be achieved by stopping all oscillators except for RTC oscillator. Although all
registers are initialized, the SRAM for both of Ephemeris data and Almanac data in backup area are held.
Command Specifications
The GXB5210 modules have a command format, NMEA-0183 version 3.01. A list of the supported UART
interface is as follows. For detailed descriptions, see the CXD2951 Communication Command Specification
document.
