Enfora Enabler II-G Assisted GPS Modem Integration Guide However, if the GPS antenna is more than 10 cm away from the module (a very likely scenario), one should consider using an active GPS antenna. An active antenna has an integrated low noise amplifier (LNA). Active antennas need power supplied to them. The power is usually routed the coax cable. One should also take care in selecting the active antenna. The LNA gain maybe too large and saturate the input to the GPS receiver.
Enfora Enabler II-G Assisted GPS Modem Integration Guide 6.5.2 RF Connector The Enabler II-G A-GPS module utilizes an ultra Miniature Coaxial Interconnect from Sunridge (MCB-ST-00T) as the on-board antenna connector. A compatible mating connector is the Sunridge MCB2-xx-xx-xxx-x series component. The cable assembly is made to order. Maximum stack height of cable connector and PCB connector is 2.0 mm. 6.5.
Enfora Enabler II-G Assisted GPS Modem Integration Guide 6.6.2 Ring Indicate The Enabler II-G A-GPS module is capable of using the Ring line to discern the type of incoming call. The indicator can be monitored via a hardware line available on the 60-pin I/O signal connector. The Ring Indicator pin is #49. The function of the Ring line depends on the type of the call received. When the module is receiving a voice call, the Ring line goes low for 1 second and high for another 2 seconds.
Enfora Enabler II-G Assisted GPS Modem Integration Guide 6.6.4 Radio Power/Reset (Pin 22) A pulse on this Active-High input resets/restarts the module. This input has a “weak pull-down” resistor internal to the module and can be left open-circuit or grounded if it is not going to be used. To initiate a reset, provide a high-pulse of at least 50 ms duration. 6.6.
Enfora Enabler II-G Assisted GPS Modem Integration Guide Figure 12 shows a variation of the connection in Figure 11 External Power Control Signal (no external processor) by using an external RC circuit to generate a pulse that will allow the processor to enter the RTC deep sleep modes. This will keep the PWR_CTL_SIGNAL signal low for at least 50ms during startup. To reset the module, power (BATT) must be cycled, and power must be removed long enough for the RC to discharge.
Enfora Enabler II-G Assisted GPS Modem Integration Guide Figure 13 shows a typical connection from an external processor to the MLG0208 module, using the external PWR_CTL_SIGNAL solution. The MLG0208 can be powered on by using the PWR_CTL_SIGNAL signal. When using PWR_CTL_SIGNAL, the I/O or serial lines can be at any voltage state desired. It is suggested that the I/O and serial lines be tri-stated or set low when the MLG208 is shutdown for an extended period of time to conserve power.
Enfora Enabler II-G Assisted GPS Modem Integration Guide Figure 14 shows a typical power on sequence for the CPU to MLG0208 interface. Note that RADIO_PWR/RST is not used, and the I/O and serial voltage levels are not a concern. Power On Sequence BATT RADIO_PWR/RST D.C. PWR_CTL_SIGNAL D.C.
Enfora Enabler II-G Assisted GPS Modem Integration Guide Figure 15 shows a Reset, or power down sequence using the RADIO_PWR/RST signal with the CPU to MLG0208 interface. Note that the I/O and serial lines MUST be either tri-stated or pulled to GND. If this is not done, it cannot be guaranteed that RADIO_PWR/RST will reset the MLG0208.
Enfora Enabler II-G Assisted GPS Modem Integration Guide 6.6.7 Using VBAK VBAK is a backup voltage that can maintain the RTC clock and alarm functions. If VBAK is not present in the system (intentionally or not) and RADIO_PWR/RST is active low, the RTC clock may still be powered if leakage voltage exists on VCC. Otherwise the RTC clock will loose power and be reset when VCC is restored. PARAMETER PARAMETER / CONDITIONS Backup Voltage (Real-Time-Clock) MIN TYP MAX VBACKUP IBACKUP 2.7 3.0 3.0 4.5 6.
