M7 GX Technical Manual

Raveon Technologies Corp.
MURS channels on channels 1-5. The user cannot change the frequency of the
M6G, only the channel number.
6.
With the unit in the command mode, change any of the default operating
parameters that must be modified as you desire. From the factory, the modems
are configured and delivered ready-to-use. Out of the box, they will
communicate on the default radio channel using the factory defaults.
Raveon
highly recommends you test them first with the factory defaults and see how
they work before reprogramming them.
In general, the parameters you may
want to modify will be:
ATFX
Frequency for this channel. Set to your frequency.
GPS x
Set the operating mode of this unit. See Section 8.1 for a list of the
various modes.
ATMY
The individual ID of this unit. Default is 0001. Number all of your
M6G
transponders with a different MYID. Raveon recommends
sequentially numbering them, starting at number 1.
ATDT
The address of the unit this modem will talk to. Default is 0001.
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).
KEYPHRASE
Enter a security key code. Use any word or phrase 1-16
characters long. It is case-sensitive. DO NOT FORGET WHAT YOU
SET IT TO! The
KEYPHRASE
is the only parameter that cannot be
read out of the
M6G
. It must be the same as the
KEYPHRASE
programmed into all the other
M6G
transponders in your system. The
factory default
KEYPHRASE
is
RAVEON
, call capitols.
SLOTNUM
This will change the TDMA slot assignment, leaving the ID (MYID)
unchanged. Typically, the ID and the slot number are the same.
Once this command is used, the TDMA slot number for this
transceiver to will not change if the ID of the device is changed. Set
SLOTNUM to -1 to force the Slot Number to be automatically set to
the MYID of the radio. This is the factory default setting.
7.
Connect your serial data device (GPS, Plotter, PC…) to the 9-pin connector on
the front of the modem.
The radio is now ready to use. Any serial data going into the modem will be
transmitted over the air, and any data received over the air will be sent out the
serial port.
Remember, that from the factory, all
M6G
modems are configured to simply work.
Plug in power and connect to the serial port at 4800 baud, and the modems will
communicate on the default channel. Change the channel frequency to your
specific frequency, and they will be ready to work on your channel.
What you will see come out of the serial port with the factory default settings (GPS
4 mode), is a
$GPWPL…
message, every time one M6G in your system transmits.
