Product Description Product Description EB-5318RF GPS module features high sensitivity, low power and ultra small form factor. This GPS module is powered by SiRF Star IV, it can provide you with superior sensitivity and performance even in urban canyon and dense foliage environment. With SiRF CGEE (Client Generated Extended Ephemeris) technology, it predicts satellite positions for up to 3 days and delivers CGEE-start time of less than 15 seconds under most conditions, without any network assistance.

DR_I2C_DIO Host I2C Interface. DR_I2C_CLK Support MEMS Sensor , 1.8V Level TIMEPULSE One pulse per second output.(1PPS) ON_OFF pin is used to command the ON_OFF EB-5318RF to turn on or off WAKE_UP System power on, 1.8V output . <Note> 2012/8/31...
OFF command is a software feature based on interrupts related to rising and/or falling edges and/or sensing of pin levels. 3. The WAKE_UP pin is an output from the EB-5318RF used to enable an external PMIC. A low on this output indicates that the EB-5318RF is in one of its low-power states (KA-only, Hibernate, or Standby mode) and requires no more than 60µA of current on the VIO_18 input.
External Interrupts. If don’t use this, just NC. 5. WAKE_UP: EB-5318RF power on, WAKE_UP will output 1.8V. 6. ON_OFF: This pin is controlled EB-5318RF power on. If EB-5318RF want to EB-365 pin to pin compactable, please ON_OFF connect to WAKE_UP. If don’t use this, just NC.
Power ON, this pin will output 1.8V board. (3.1Vdc to 3.5Vdc) RESET This is the main transmits channel for Low Active, when EB-5318RF is accepted this outputting navigation and measurement data single, EB-5318RF going to Hibernate mode. If to user’s navigation software or user written want EB-5318RF up, need input ON_OFF software.

Note: A valid status is derived from all the parameters set in the software. This includes the minimum number of satellites required, any DOP mask setting, presence of DGPS corrections, etc. If the default or current software setting requires that a factor is met, then if that factor is not met the solution will be marked as invalid.

NMEA Input Command A). Set Serial Port ID: 100 Set PORTA parameters and protocol This command message is used to set the protocol (SiRF Binary, NMEA, or USER1) and/or the communication parameters (baud, data bits, stop bits, parity). Generally, this command would be used to switch the module back to SiRF Binary protocol mode where a more extensive command message set is available.

E). LLA Navigation lnitialization ID: 104 Parameters required to start using Lat/Lon/Alt This command is used to initialize the module for a warm start, by providing current position (in Latitude, Longitude, Altitude coordinates), clock offset, and time. This enables the receiver to search for the correct satellite signals at the correct signal parameters.
