5.8 Power
External Power Source: 6 – 32V* (*No ORBCOMM Tx from 6-10.5 VDC)
10.5 – 32V (All features supported)
Typical Power Consumption at 12V (not including other modem features):
· Transmit - ORBCOMM 22.26 Watts
· Transmit - GSM 7.80 Watts
· Transmit – Iridium 11.4 Watts
· Standby - ORBCOMM 11.4 Watts
· Standby - GSM 0.24 Watts
· Standby – Iridium 1.02 Watts
· Sleep Mode 25µA (max)
Note: The QPRO uses a switching mode DC-DC converter power supply. This means that the current draw
of the QPRO drops with an increase in the input voltage. QUAKE Global recommends that the QPRO be
connected to a power supply through a 5 Amp fast-blow fuse.
DC Input power to QUAKE QPRO modems is +6.0V to +32.0VDC. Input voltage outside this range will
result in damage to the modem and void the warranty.
5.9 Operation Modes
Transmit: In this mode the unit is sending an outgoing message. It could be from any programmed condition
including an alarm, an application event, a scheduled report, or in response to an over-the-air inquiry. The
Q4000 may also query the satellite or GSM network looking for incoming messages.
Standby : In this mode the Q4000 is in a constant receive mode. (Depending on the availability of the
satellite, the unit will be receiving satellite downlink information or searching for a downlink.) The RF, digital
signal processor, and control processor portion of the modem are active in this mode.
Data Collection: In this mode the control processor (CP) is active. The Q4000 may be sampling data inputs
through the serial port or interacting with other Q4000 Subsystems. The CP is used to power on, control and
collect data from the RF Subsystem. The CP is active during its interaction with these subsystems, but does
not need to stay active while the other subsystems run their tasks
Sleep: In this mode the Q4000 is completely shutdown. The processors and memories are off. Only the
real-time clock (RTC) is running, maintaining GPS time. The Q4000 can be configured to shutdown when
DTR goes low, or it can be programmed to shutdown with software, as desired. A normal shutdown includes
a data save to Flash consisting of unsent messages, and configuration parameters. A power cycle, external
DTR pulse, or RTC alarm will wake-up the unit.
