1. See
Table 2-2,
, for complete operating current consumption specifications.
2. Asserted can wake the modem from sleep mode.
3. Input resistance high impedance >1M ohms
4. Pins 3 and 4 provide a continuous output that cannot be disabled. If any external voltages are applied to these
pins it may cause permanent damage and will void the warranty. The combined current capacity of pins 3 and 4
cannot exceed 650 mAs.
5. Pin 5 (AUX_TX_RS232) and Pin 6 (AUX_RX_RS232) are the DPL ports in the QPRO with Iridium version of the
modem.
6. If the QPRO contains an internal GPS, then Pin 12 (GPS_RX_RS232) is not connected. Otherwise it’s part of
the serial port.
