M7 GX Quick Start Guide 2Raveon Technologies
1. Safety / Warning Information
1.1.Blasting Caps and Blasting Areas
To avoid possible interference with blasting operations, turn
off this radio or remove the DC power when you are near
electrical blasting caps or in areas posted: “Turn off two-
way radio.” Obey all signs and instructions.
1.2.Potentially Explosive Atmospheres
Turn off your radio prior to entering any area with a
potentially explosive atmosphere. Do not install this product
for use in areas with potentially explosive atmospheres. Do
not remove, install, or charge batteries in such areas.
Sparks in a potentially explosive atmosphere can cause an
explosion or fire resulting in bodily injury or even death.
Use this manual in conjunction with the M7 GX
Technical Manual, which contains important safety,
licensing, and FCC information.
2. Overview
Raveon’s RV-M7 GX series of GPS transponders are a
rugged high-speed data modems with a built-in 12-channel
GPS receivers. The M7 GX may be configured for different
GPS applications, including:
Transponder: Periodically transmit position and status. TX
only.
RavTrack PC: Connect the M7 GX to a personal computer
running RavTrack PC (or other PC software) to
view a map showing location.
Radar Display: Connect M7 GX to a marine plotter or radar
display, and icons will appear on the display.
GPS display: Connect M7 GX to a hand-held or mobile GPS,
and icons will appear on the display showing the
location of all other M7s.
For privacy and security, over-the air encryption is standard
on every M7 GX radio. For network versatility, the M7 GX
incorporates a 16-bit identification code. All M7 GX
transponders may be set to store-and-forward messages
from other M7 GX transponders.
M7 GX Quick Start Guide 3Raveon Technologies
3. Operation
The M7 GX operates in a number of different “GPS Modes”,
each mode specific to the application it is being used in.
The mode of operation is set with one simple command, the
GPS x command. The following table summarizes this.

4. Electrical Inputs and Outputs
The front panel of the M7 GX modem has these features:
1. RF connector
2. Power LED
3. Status LED (Receive data = green, TX = red)
4. 9-Pin Serial I/O connector
5. DC Power Jack
4.1.LEDs
The status LED visually show the current status of the radio.
Status LED (TX) This LED blinks red when the transmitter
keys and is putting out RF power. It blinks green upon the
reception of data or RF carrier.
Power LED (PWR) This LED does a short blink, once
every two seconds, indicating to the user that the power to
the modem is ON and the modem is working. When the
modem is in the command mode, this LED will blink on and
off, once per second.
When the GPS is trying to acquire satellite lock, the Status
and Power LEDs will alternately blink back and forth. This
usually takes 10-20 seconds upon power-up or loss of
satellite signal.
4.2.DC Power
DC power for themodem is connected to the 2-pin DC
power input jack labeled DC IN. Use the supplied cable to
connect the DC power. The red wire is positive (+) and the
black wire is negative (-) .
5. RS232 Serial I/O Connector
The RS232 9-pin serial I/O connector is a female 9-
pin D-subminiature connector having the following
M7 GX Quick Start Guide 6Raveon Technologies
pins configuration. It is pinned out so that it may be plugged
directly into a computer or PC’s 9-pin COM port.

This pin-out allows it to be directly plugged into a
computer’s 9-pin serial port using a conventional 9-pin RS-
232 serial cable. To connect it to a modem, or peripheral
that has a serial port, you will need a “null-modem” cable.

6. Configuring the M7 GX
6.1. Overview
There is a “Command Mode” used to program and
configure the M7 GX. In the Command Mode, the M7 GX
modem accepts commands via the serial port and the user
may configure the internal parameters of the unit, such as
frequency and ID codes.
6.2. Command Mode
The M7 GX modem may be put into a “Command Mode”, by
entering a sequence of three plus characters (+++). Using
serial communications software such as HypterTerminal,
send the 3-character command sequence “+++”.
When the M7 GX modem first enters the Command Mode, it
sends its model number out its serial port, and then an
“OK”.
6.3. Setting a Parameter
To set a parameter in the M7 GX modem, enter the
Command Mode as described above, then enter the proper
command, a space, the parameter, and then a carriage
return. For Example, to set the destination address of the
M7 GX modem to 25, enter the following command:
ATDT 25 <CR>.
6.4.CONFIG Button
There is a small push-button inside the M7 to assist. This
“CONFIG” button may be pressed at any time, and forces
the M7 GX into a known state. The CONFIG button is
located inside the M7 GX.
The default settings that the M7 GX will revert to when the
CONFIG button is pressed are:
1. Serial port 9600 baud, 8 data bits 1 stop, no
parity
2. Serial port flow control is off.
M7 GX Quick Start Guide 8Raveon Technologies
Even though the serial baud rate reverts to 9600 baud when
the CONFIG button is pressed and the IO port is RS232, it
will revert back to the settings programmed into the M7 GX
once the Command Mode is exited.
