Enfora Enabler II-G Assisted GPS Modem Integration Guide The SDK117 has three antenna cables. One cable is for connection to the RF connector for quad band GSM/GPRS antenna. The second RF cable is for a passive PCB patch antenna that can be used for the GSM/GPRS antenna. The third antenna is for the passive GPS patch antenna. However, if the GPS antenna is more than 10 cm away from the module (a likely scenario), one should consider using an active GPS antenna.
Enfora Enabler II-G Assisted GPS Modem Integration Guide Figure 7 MCB2 Cable Assembly 6.6. Control Connector Signal Descriptions and Functions 6.6.1. Input Power The Enfora Enabler II-G A-GPS module uses a single voltage source of VCC=+3.3V to 4.5V. (The exact values of the uplink currents are shown in Tables5.3.1 GSM Operating Power and 5.3.2 GPRS Operating Power). The VCC lines (pins 1 to 6) should be connected on the application board.
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 RESET Figure 9 External Power Control Signal (no external processor) MLG0208PB001 28 Version1.
Enfora Enabler II-G Assisted GPS Modem Integration Guide Figure shows a variation of the connection in Figure 9 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 shows a typical connection from an external processor to the Enfora Enabler II-G A-GPS module, using the external PWR_CTL_SIGNAL solution. The Enfora Enabler II-G A-GPS 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.

The following modes of operation are supported in the module: Autonomous, Mobile Assisted, and enhanced Autonomous 8.1. Autonomous The autonomous mode provides unassisted GPS data. The GPS antenna must have a clear view of the sky in order to obtain a signal and provide GPS location data.
Enfora Enabler II-G Assisted GPS Modem Integration Guide of bytes downloaded per connection will be less as compared to the LTO file used in the Enhanced Autonomous mode. The following parameters will need to be programmed in order to provide data connection parameters to the network and location assistance server: AT+CGDCONT=1,"IP","APN" AT%CGPCO=1,"username,password",0 AT$AREG=2 AT$GPSDST=”1.2.3.4”,”5.6.7.8”,1265 interface AT$GPSSRC=1270 AT$LTOFREQ=4 - Set GPRS connection with Network.
Enfora Enabler II-G Assisted GPS Modem Integration Guide data for the entire constellation. This data is around 30 Kbytes and would be valid for up to 48 hours. If the LTO data file is downloaded every 4 hours, then it would only download about 2 Kbytes of data or so. It does not download entire 30 Kbyte file every time. The next section discusses the recommended approach for downloading the file. It is not necessary for the GPS antenna to have a clear view of the sky in order to operate.
Enfora Enabler II-G Assisted GPS Modem Integration Guide 9. SIM Operation 9.1. Provisioning the SIM The SIM can support optional features or services.
