 TXD : Modem UART TX line;
 RTS : Pin can serve several functions, based on PCB jumpers settings:
o Modem UART RTS signal;
o GPS receiver UART RX line;
 CTS : Pin can serve several functions, based on PCB jumpers settings:
o Modem UART CTS signal;
o GPS receiver UART TX line;
Modem Control and Status
 DTR : Modem DTR signal;
 DCD : Modem DCD signal;
 RI : Modem RI signal;
 STATUS : Pin can serve several functions, based on PCB jumpers settings:
o Modem STATUS signal;
o qJam interface QIO line;
I2C BUS
 I2C SDA : I2C Bus SDA line, connected to UID NVM chip and qJam interface;
 I2C SCL : I2C Bus SCL line, connected to UID NVM chip and qJam interface;
 Both lines are NOT connected to Modem I2C bus.
Minimal connection, power On / Off
To get Device fully functional, just part of lines to be used:
 5VIN & GND (Device Power);
 ENABLE (Device Power On/Off Control : DC/DC On/Off);
 ON (Modem On/Off Control);
 RXD & TXD (Modem UART TXD & RXD lines);
 I2C SDA & I2C SCL (UID NVM & qJam interface).
To get Modem ON these steps to be done:
 Bring the power to 5VIN & GND pins;
 Turn ENABLE pin On (HIGH);
 Turn ON pin On (HIGH) for 1 sec;
