Document 1135-0902, REV K 23
3.5V Power 4.1.4
There are two pins that provide 3.5 VDC continuous power: Pin 5 and Pin 6. The total current added up
between these two pins cannot exceed 650 mA. Do not include these pins on the connector if they are not
being used.
Warning: Connecting these pins incorrectly could damage the unit and void the warranty.
RS-232 Ports 4.1.5
The Q4000 has up to five RS-232 serial ports.
1) The Main Transport Socket (MTS) Port implements QUAKE’s Communication Protocol (QCP).
2) The Logger Port provides diagnostic data for the user and the ability to debug and configure the
custom application.
3) The third, fourth and fifth serial ports are only available depending on the specific Q4000 model.
All serial ports support baud rates up to 115.2 Kbps. All ports are protected against shorts to both the BATT+
and BATT- lines. The serial ports meet the standard voltage level for RS-232 operation. The chart below
shows the relationship between modem type and serial port availability.

Warning: There are important hardware differences between various
Q4000/QPRO models depending on the part number/network. Developers
who plan to use multiple network configurations with Q4000/QPRO hardware
should ensure that their application will run across all platforms.
For example, the AUX port is not available in Iridium and Inmarsat networks.
Developers planning to use serial ports must be aware that the AUX port is
not available on all configurations of the Q4000/QPRO. Note that the AUX
port may lose bytes at speeds over 57600 bps. Information on the
availability of serial ports is contained in 2.1Error! Reference source not
