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.

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-

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.

7. Setup and Initial Configuration
1. Connect a DC power source to the DC IN connection
on the front Connect a DC power source to the DC IN
connection on thefront of the modem.
2. Connect a good quality antenna, cut to the operating
frequency, to the BNC connector on the front of the
modem.
3. Connect a computer terminal, or PC computer
running HyperTerminal, to the 9-pin I/O connector.
The factory default serial ports settings are 4800 bps,
8 data bits, 1 stop, no parity.

M7 GX Quick Start Guide 13 Raveon Technologies
4. Put the M7 GX into the command mode. (enter +++
per Section 0)
5. Program the GPS mode. See the table on Page 3 to
identify the mode to use, and set it with the GPS x
command. Type GX and press enter to see an
overview of the current GPS related features and
configuration. For in-vehicle transponders that do not
connect to PCs or displays, it is usually GPS 1 mode.
For M7’s connected to a PC running RavTrack PC
software, it is set to GPS 2.
6. Program the modem’s operating frequency to your
desired operating frequency. This is done with the
ATFX xxx.xxxxx command.
7. Program the ID in the unit. Sequentially number the
M7 GX units in your system, starting with 1. Use the
ATMY command to set the ID.
8. Program the ID to which this unit will send its data to.
Typically this is the ID of the “Base” unit. Use the
ATDT xxxx command to set the ID that this unit will
transmit to.
9. Program the SLOTNUM. This is the TDMA slot number
that this unit will transmit in. By default it is the same as
its ID. Important! All radios in your system must use
different SLOTNUM settings.
10. ATMK The network address mask. Default is
F000. This means this unit will receive all
transmissions from any other unit with an ID
beginning with 0 (0001 thru 0999).
11. KEYPHRASE Enter a security key code
“keyphrase”. Use any word or phrase 1-16
characters long. It is case-sensitive. DO NOT
FORGETWHAT YOU SET IT TO! The KEYPHRASE
is the only parameter that cannot be read out of the
M7 GX. It must be the same as the KEYPHRASE
programmed into all the other M7 GX transponders in
your system. The factory default KEYPHRASE is
RAVEON, call capitols.
12. To see an overview of how the modem is configured,
use the SHOW command. To see an overview of

M7 GX Quick Start Guide 14 Raveon Technologies
how the GPS features are configured, use the GX
command.
13. Verify the SLOTTIME and TDMATIME are set
appropriate for your system. Consult the user manual
if you are not sure. The defaults are 200mS
SLOTTIME and 10 second TDMATIME, which will
give you 50 slots (numbered 0-49) to track 49
transponders.
14. Once the unit is configured, type EXIT to exit the
command mode.
Remember, that from the factory, all M7 GX GPS
transponders are configured to simply work. Plug in power
and they will lock onto the GPS satellite signal and begin
transmitting their positions and status in their appropriate
time slot.
7.1. Enabling Repeater Features
Refer to the technical manual for advanced repeater
configuration instructions. To quickly enable repeating of all
data sent from/to units 1-999, use the REPEAT 1
command. This will enable the repeater function, and
configure it to repeat all messages, position, and status
transmissions.
7.2.Set the Transmission Report rate
Use the TXRATE xx command to set the report rate, in
seconds, for the M7 GX transponder. For example, if you
wish the M7 to report every 5 minutes, set the report rate to
300 seconds (TXRATE 300).
If the M7 GX should report position and status when it is
moving, set the TXRATE xx to the desired time between
position transmissions. Then, program the IDLERATE xx
to the desired number of seconds between reports when the
unit is not moving (idle).
Important!: Set the minimum distance the unit must move
for a transmission occur with the TRIGDX xx command. If
TRIGDX is set to zero, then the unit will always report at the
interval set with the TXRATE xx command. This is the
factory default setting.
For example, to transmit every 2 minutes when idle, and
every 10 seconds when moving more than 500 meters, use
these commands:

M7 GX Quick Start Guide 15 Raveon Technologies
IDLERATE 120 (to set the idling update interval to 2
minutes.)
TRIGDX 500 (tells it to report at the IDLERATE if it does
not move this many meters)
TXRATE 10 (configures it to report every 10 seconds
whenever it is moves more than TRIGDX
meters)
7.3. Device Addressing
Security Key
The security KEY programmed into every M7 GX
transponder ensures that only M7 GX transponders with the
exact same security code can receive position and status
information. The security key is case sensitive, so
“Raveon” and “RAVEON” are two different keys. The
factory default is “RAVEON”.
7.4.Addressing Basics
Addressing is used to differentiate one M7 Transponder
from another. Each must have a unique ID number
programmed into them, so that when a position report is
received, the ID of the M7 GX that sent the message is
known. This is called the MYID.
Each M7 GX has an ID programmed into it, and is
represented as a 4 digit number. M7 GX IDs may be any
number between 0001 and 9999. The unit’s own ID is
programmed with the ATMY xxxx command, and the ID of
the destination modem it sends its messages to (the
Destination Address) is configured with the ATDT xxxx
command.
The default Address Mask is F000, which means the M7 GX
will receive a transmission from any other M7 as long as the
fist digit matches, in this case, is a 0.
For example, to set the MYID of your M7 to 17, enter:
MYID 17 <enter>
To set your M7 to send its position and status data to M7
number 1, enter:
ATDT 1 <enter>
To receive all messages from units with IDs 1-999, and
exclude 1000-9999, set the mask to:

M7 GX Quick Start Guide 16 Raveon Technologies
ATMK F000 <enter>
7.5.Time Slots
For optimum efficiency in a M7 GX system, begin
sequentially numbering the MYID of the M7 GX
transponders at ID 0001. The second M7 should be ID
0002, and so on.
The M7 GX transponders have internal clocks with 20 ticks-
per-second. They can measure time and initiate
transmissions 20 times every second (every 50mS). The
factory default allocation is each TDMA time slot is 200mS
long, and thus in 10 seconds, up to 49 M7 GX transponders
may report position. These parameters are programmable,
and may be re-configured based upon the type of system
they are used in. Program the slot time with the SLOTTIME
xxx command, where xxx is in milliseconds.
For over-the-air rates of 4800 baud, Raveon Suggests using
a SLOTTIME of 200mS when using a repeater, or 100mS if
there is no repeater in the system.
For over-the-air rates of 9600 baud, Raveon Suggests using
a SLOTTIME of 150mS when using a repeater, or 50mS if
there is no repeater in the system and no encryption used. If
no repeater is used, but encryption is enabled, then use
70mS for the SLOTTIME.
A TDMA “Frame” time is the time it takes all units in your
system to transmit. This is configured with the TDMATIME
xx command. The factory default is 10 seconds, so every
10 seconds, each M7 GX is allocated a time-slot that it may
use to transmit position in. The TDMA frame must be set
long enough for all units to transmit. For example, if you
have 199 M7s, and use 200mS TDMA slots, then the
TDMATIME should be set to 40 seconds.
All TDMA frames are synchronized automatically in all M7
GX Transponders to the top of the minute. Slot 0, frame 0
is at the top of each minute. Slot number 0 is used for future
protocol options, and should not be assigned to any unit.
8. Installation
1. Secure the M7 modem using the mounting holes on
the side flanges of the unit.

M7 GX Quick Start Guide 17 Raveon Technologies
2. Connect a DC power source to the DC IN
connection on thefront of the modem. Use the
supplied cable, or 18AWG wire, and connect the
RED wire to +, and the black wire to –(ground).
The black wire and the case of the M7 should be
connected to earth ground.
3. Connect a good quality antenna, tuned to the
operating frequency, to the RF connector on the
front of the modem. Use a good antenna, and
place is at as high-above obstructions as possible.
4. A separation distance of at least 20 centimeters
must be maintained between the transmitter's
radiating structures and the body of the user or
nearby persons.
5. Connect a GPS antenna to the SMA connector of
the M7 GX. Although a passive antenna may work
if the cable length is very short, it is recommended
that an amplified antenna be used, rated for 3.3V
operation.
6. Connect the computer, terminal, controller, or other
hardware device that will be using the M7 modem
to its DB-9 serial I/O connector using a shielded
cable. Secure it to the M7 with the two mounting
screws on the sides of the DB-9 connector.
7. If the antenna is mounted out doors, us a lighting
arrestor in-line with the antenna, and properly
ground the antenna and the M7 chassis to an earth
ground.
8. Connect Digital Inputs. The stock M7 GX has up to
3 digital inputs, using the input pins of the RS-232
serial port. An open circuit or ground is a 0, and if
they are connected to a positive voltage greater
than 3V, they are a digital 1.

9. Operation
Once power is applied to the M7 GX, the internal GPS will
begin to try to lock onto the GPS satellites.
The two LEDs on the front of the M7 will begin to alternately
blink red back-and-forth every second.
After 10 to 60 seconds, depending upon the satellite
strength, the red alternating blinking will stop. This indicates
the internal GPS receiver is locked onto GPS satellite
signals, and has a position fix.
The M7 GX will only transmit if it has GPS lock. If the GPS
antenna is broke or obscured, the unit will not report
position or status.
When it is locked to GPS, it will transmit its position and
status at the interval programmed into the TXRATE
parameter.
Refer to the M7 GX Technical Manual for details on all of
the events that will trigger a transmission.
At the interval set by the TXRATE, you will see each
transponder’s STAT LED blink red when it transmits its
position.
At the unit used to receive position reports, you will see the
STAT LED blink green when it receives a signal over the
radio channel. The receiving station will output the received
position report using its RS232 serial port. The message
format that the postion report is sent out the serial port
depends upon the GPS mode of the unit. If it is in GPS 2
mode, it will output it in the PRAVE format, which is the
format used to communicate with the RavTrack PC AVL
software program.
