6.5. Antenna<br />
The GSM0308-xx module has one RF antenna connection on the module. The connection is<br />
for the GSM section of the module.<br />
6.6. Control Connector Signal Descriptions and Functions<br />
Please note that the following descriptions are intended to<br />
provide hardware-level definitions. In some cases, specific<br />
lines will have no firmware functionality implemented.<br />
Information for each hardware-specific feature will be noted<br />
in the appropriate section.<br />
6.6.1. Module Power (Pins 85, 87, 89, 91, 93, 95, 97, 99)<br />
The Enfora <strong>Enabler</strong> <strong>II</strong>I-G module uses a single voltage source of VCC=+3.3V to 4.5V. (The<br />
exact values of the uplink currents are shown in the tables in section 5.3.1.)<br />

Connector<br />
The uplink burst will cause strong ripple on the voltage<br />
lines and should be effectively filtered. It is recommended<br />
that 1000 to 2000 μF of capacitance be placed as close to<br />
the modem I/O connector as possible.<br />
It should be noted that the input voltage level should not<br />
drop below the minimum voltage rating under any<br />
circumstances, especially during the uplink burst period.<br />
