QUAKE Global evaluation and development kits include a demo account that can be activated for
at least 60 days and will allow unlimited ORBCOMM or Iridium satellite data to be sent and
received during this time. The GPRS data plan must be provisioned by the customer. Contact
[e-mail] for more information on provisioning for evaluation and
development kits. Getting the demo account activated and provisioned for email usually takes
about 1 day or less once QUAKE Global receives the desired destination email address.
Initially, many users create a new email address for modem messages. It is best to set up this
new mailbox for testing purposes to avoid a flood of modem messages into your daily use email.
See Chapter 4 for more information on activating and provisioning the modem.
2.8 Powering On/Off
2.8.1 Power on
The modem can be powered on in one of three ways:
1. the application of power;
2. the Real Time Clock;
3. assert Data Terminal Ready (DTR).
A typical operating scenario for a Q4000/QPRO is to power on (wake from sleep mode), perform
a number of activities, and power off again (enter low-power sleep mode). It is important to
understand the various ways to power the Q4000/QPRO on and off.
Application of Power - When an external power source is first connected to the modem, the
device powers on, the software boots, and the device begins operation. When the modem has
powered itself down and is in sleep mode, its power consumption is low.
Real Time Clock (RTC) - The on-board Real Time Clock (RTC) may generate a signal that
causes the modem to power on from sleep mode. The RTC does not maintain the time when the
power source is removed. The time is reset when the modem establishes communication with the
first available network (GSM, GPS or Satellite Communication).
Data Terminal Ready (DTR) - If ORBCOMM configuration parameter 0x2f, pwr_dwn_mode=0, is
configured and the MTS DTR line is asserted, the unit powers up or awakens from sleep mode
(as long as power is applied). If the MTS DTR line is deasserted, the modem will initiate a
controlled power-down sequence. For Iridium and Inmarsat modems, use QCFG parameter
0xb5 (QCFG_POWER_DOWN_MODE) instead of 0x2f. See Section 7.2 for information on
changing QCFG parameters.
The DTR line has two functions:
1. It behaves as a Wakeup for the Q4000. In this functionality, a 1.8 V rise on the DTR line
will wake up the Q4000.
2. It is a normal RS-232 signal on the MTS port. During this operation of the MTS port, it
utilizes normal RS-232 levels with a 6V threshold, as specified in the Technical Data
Sheet.
The DTR line does not support CMOS levels when it is behaving as a regular RS-232 serial port.
