2.0 Regulatory Compliance FCC 2.1 Integration Considerations and Installation Requirements The Enabler IIG OEM GPRS modem is designed for use in a variety of host units, "enabling" the host platform to perform wireless data communications. However, there are certain criteria relative to integrating the modem into a host platform such as a PC, laptop, handheld or PocketPC, monitor and control unit, etc. - Page 7 If used in a "mobile" application where the antenna is normally separated at least 20 cm (7.9 in) from the human body during device operation, then an appropriate warning label must be placed on the host unit adjacent to the antenna. The label should contain a statement such as the following: WARNING RF exposure.

Page 28: Circuit Protection
6.6 Circuit Protection Other than the basic low level ESD protection within the module’s integrated circuits (typically 2000 V), the Enabler IIG does not have any protection against ESD events or other excursions that exceed the specified operating parameters. The only exception is that the remote SIM lines on the main I/O connector do have additional ESD protection that should handle standard human-model contact ESD events. -
Page 29: Rf Connector
6.8.1 Input Power The Enfora Enabler IIG module uses a single voltage source of VCC=+3.3V to 4.5V. (exact values of the uplink currents are shown in Tables5.3.1 GSM Operating Power and 5.3.2 GPRS Operating Power). The lines (pins 1 to 6) should be connected on the application board. -
Page 30: Ring Indicate (Pin 49)
Ring Indicate (Pin 49) The Enabler IIG 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. -
Page 31: Radio Power/Reset (Pin 22)
6.8.3 Radio Power/Reset (Pin 22) The Reset signal is used to force the modem to start at a known state. When the Reset is pulled low the modem will immediately suspend any function and will not exit the reset state until the Reset signal is released to be pulled high. -
Page 32: Turning On The Enabler Iig
6.8.4.2 Turning OFF the Enabler IIG The Enabler IIG can be turned OFF by either a low pulse on the PWR_CTL line or, or by a software command (ATt$OFF - see AT command guide for further information). Section 6.8.4.3 describes various ways to provide the signal. - Page 33 Typical use controlling PWR_CTL from a microcontroller: Typical connection of PWR_CTL to modem: This next figure shows a typical connection to the Enabler IIG module in a machine-to-machine application using the external PWR_CTL signal, when there is not an external processor controlling the power on/off states.

Enabler IIG module, using the external PWR_CTL signal. The Enabler IIG can be powered on by using the PWR_CTL signal, and reset with the RESET signal. When using the PWR_CTL, the I/O or serial lines can be at any voltage state desired. It is recommended that the I/O and serial lines be tri-stated or set low when the modem is shutdown for an extended period of time to prevent any leakage of current from the processor to the modem. -

Page 36: System Shutdown Methods
6.8.6 System Shutdown Methods There are several ways to control the modem when using either the PWR_CTL_SIGNAL signal or the RADIO_PWR/RST signal. Figure 12 shows a power sequence when the PWR_CTL_SIGNAL signal is used to power up. Figure 12 - Power On Using Power Control Signal Figure 13 shows a power on with the PWR_CTL_SIGNAL signal, but a shutdown with the RADIO_PWR/RST signal. -
Page 37: Figure 14 - Power On/Off Using Power Control Signal Tied To Ground
Figure 14 shows the power on/off sequence when PWR_CTL_SIGNAL is tied to GND. Note that the GPIO and serial port lines should not have any voltage on them, with PWR_CTL_SIGNAL tied to GND the system will startup even if there is a voltage on the lines, but it is not preferred. This mode will NOT allow for the RTC sleep to function. Figure 14 - Power On/Off using Power Control Signal tied to Ground GSM0128IG001 Revision Draft –... -
