1. General In ormation
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, in a
blasting area, or in areas posted: “Turn off two-way radio.”
Obey all signs and instructions.
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.
Note: The areas with potentially explosive atmospheres referred
to above include fueling areas such as below decks on boats,
fuel or chemical transfer or storage facilities, areas where the air
contains chemicals or particles, such as grain, dust or metal
powders, and any other area where you would normally be
advised to turn off your vehicle engine. reas with potentially
explosive atmospheres are often but not always posted.
2. Electrical Inputs and Outputs
The front panel of the M7 modem has these features:
1. RF connector
2. Status ED
3. Power ED (PWR)
4. 9-Pin Serial I/O
connector
5. DC Power Jack
2.1. LEDs
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.

M7 Quick Start 3 Raveon Technologies Corp.
2.2. 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.
2.3. RS232/EIA232 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.

3. Using the M7 Modem
This section describes how to use the M7 in the Packet Mode of
operation. See the M7 Technical Manual for an explanation of
both the Packet and the Streaming mode. The Packet Mode is
generally considered the easiest and most reliable operating
mode.
Remember, that from the factory, all M7 modems are configured
to simply work. Plug in power and connect to the serial port at
9600 baud, and the modems will communicate on the default

M7 Quick Start 4 Raveon Technologies Corp.
channel. Change the channel frequency to your specific
frequency, and they will be ready to work on your channel.
3.1. Setup
1. Connect a 12 volt DC power source to the DC IN
connection on the front 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 9600 bps, 8 data bits, 1
stop, no parity.
4. Turn the modem on, and enter the “Programming Mode”
by typing +++ into the modem. The Power LED will begin
blinking at once-per-second.
5. Program the modem’s operating frequency to your
desired operating frequency. This is done with the ATFX
xxx.xxxxx command.
6. Using the T commands, change any of the default
operating parameters that must be modified. From the
factory, the modems are configured and shipped ready-
to-use. Out of the box, they will communicate on the
default radio channel using the factory defaults. In
general, the parameters you may want to modify will be:

4. Installation
1. Secure the M7 modem using the four mounting holes
on the side flanges of the unit.
2. Connect a DC power source to the DC IN connection
on the front of the modem. Use the supplied cable,
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. 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 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.

6. 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.
5. User Serial Port Commands
5.1. Command Mode
The M7 modem may be put into a “Command Mode”, by entering
a sequence of three plus characters (+++). To keep the M7
modem from unintentionally entering the Command Mode
because of the +++ pattern occurring in a stream of data
entering the modem, there must be a pause in the data stream
before the +++ as well as a pause after the +++ is sent. If either
pause is missing, the modem will not enter the command mode.
ATDT ?. The modem will respond by listing a brief description of
the command. To see a list of all commands, type HE P.
5.2. Exiting the Command Mode
There are three ways to exit the command mode. They are:
1. ATSV Issuing the ATSV command saves the current
configuration to non-volatile memory, and then returns to the
normal operation mode.
2. ATCN Issuing the ATCN command does not save the
current configuration, but it does cause the modem to
continue to operate.
3. Time Out. fter a pre-set amount of time (60 seconds is
the factory default time), the modem will automatically exit the
Command Mode, and continue normal operation. Changes
will not automatically be saved. This time-out duration may be
set with the ATCT command.
