6.7.2 RF Connector The Enabler IIG utilizes an 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. 6.8 Control Connector Signal Descriptions and Functions 6.8.1 Input Power The Enfora Enabler IIG module uses a single voltage source of VCC=+3.3V to 4.5V.
6.8.2 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. 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.
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. Once the transition from low to high is complete, the modem will boot. The Reset signal is falling edge triggered, so the reset function is set immediately when the signal is pulled low.
*The OFF Delay is controlled by the AT$OFFDLY command. A value of 0 disables the PWR_CTL line from turning the module off. 0 is the default value. ! To enable the module to switch-OFF via PWR_CTL one must set AT$OFFDLY to a value other than 0. The valid range is 100 to 1000 milliseconds. 6.8.4.1 Turning ON the Enabler IIG Pulling the PWR_CTL line on the Enabler IIG LOW for at least 50ms (after Vbat is applied and stabilized) is required to turn it ON. Section 6.8.
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. The RTC deep sleep functions will NOT function since the PWR_CTL pin is tied low, the processor will never stay in a “RTC Sleep” mode.
Figure 10 – External Power Control Signal (no external processor) Figure 10 shows a typical connection from an external processor to the 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.

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.
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.
6.8.7 Serial Interface (9 Pin I/F) (Pins 41, 43, 45, 47, 49, 51, 53, 55, 57) The modem provides a standard 16550 UART serial interface to the host. The data interface operates at CMOS level. The Enabler IIG is designed to be used like a DCE device. RxData is the serial data from the modem to the host. TxData is the serial data from the host to the modem.
6.9 General Purpose Input/Output Interface (GPIO) (Pins 14, 18, 27, 28, 30, 32, 34, 39) Eight general-purpose signals are provided. Each of these signals may be selected as inputs or outputs. They may be used independently as a user-specified function, or may be used to provide modem control and status signals. Several examples of modem control signals are: power shutdown command, register/deregister on network command, and transmitter disable. See GSM0128AT000 for AT Command control.
