92 kbps maximum continuous throughput
Antenna detection (see note below)
In order for the antenna detection circuitry to work properly, the GSM/GPRS antenna that is
selected must have a 10Kohm DC resistance to ground from the center of the coax antenna cable.
The user must purchase an antenna with this feature or our GSM detection will not work. This type
of antenna can be obtained through the following antenna manufacturers: Taoglas, Hirschmann Car
Communications, and Tyco Electronics.
o GSM Serial Port - RS-232 serial port used to upgrade the GSM module’s firmware.
Pins: 7(Rx), 9 (Tx), and GND (Pin 11, 19, 21, 30, or 40).
• External GSM
o GSM Serial Port – A Q4000 that DOES NOT include an internal GSM module has the option
to use one of the RS-232 serial ports to communicate with an external GSM module, or it
can be used as an additional serial port with the use of a custom application. For example,
the following pins could be used:
Pins: 8 (Rx), 10 (Tx), and GND (Pin 11, 19, 21, 30, or 40).
Use only approved GSM antennas

MTS Serial Port-
The Main Transport Socket port; known as the MTS port, is an RS-232
port which implements the QUAKE Communications Protocol (QCP). For Q4000 models that
support Orbcomm this port also supports the Orbcomm Serial Interface.
Pins: 13 (Rx), 15 (TX), 16 (DSR), 17 (DTR), 18 (DCD, and GND (Pin 11, 19, 21, 30
and 40)
Exceeding an RF input power level of +10dBm may result in damage to the receiver and will void the
warranty.
