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 UHF data modems with a built-in 12-channel GPS receivers. The

M7 GX has ½ to 5 watts of RF power output, and operates as both a

GPS transponder for tracking, and a radio modem.

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 Displa : Connect M7 GX to a marine plotter or radar display, and icons

will appear on the display.

GPS displa : 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.

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:

. 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 1 -2

seconds upon power-up or loss of satellite signal.

4.2. DC Power

DC power for the modem 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 (-). Its

connection is optional, as the user may alternately apply power to Pin 9

and ground to pin 5 of the 9-pin I/O connector. If the power cable run is

over 3 feet long, Raveon recommends at least 18 AWG wire be used.

The M7 modem is supplied with a 6-foot DC power cable, Raveon part

number 1C738-1.

Note: The M7 has in internal 3-amp mini-fuse (automotive type) to

protect it and its power source against reverse voltage and serious

hardware failures.

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 pins

configuration. It is pinned out so that it may be plugged

directly into a computer or PC’s 9-pin COM port.

User may supply the DC power to the

Note: RS-232 signals use positive and negative voltages to represent digital 1s

and 0s. A positive voltage is a 0, and a negative voltage is a digital 1.

M7 GX Quick Start Guide 6 Raveon Technologies Corp.

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. 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 H pterTerminal.

When the M7 GX modem first enters the Command Mode, it sends the

phrase “RV-M7” out it serial port, and then an “OK”.

6.2. 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 the enter key. For Example, to set the destination

address (DT parameter) of the M7 GX modem to 25, enter the following

command: ATDT 25 <CR>.

6.3. 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 parit

2. Serial port flow control is off.

3. ATCT setting set to 60000 (60 second time-out)

Even though the serial baud rate reverts to 96 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.
