Specifications

M7 GX Technical Manual 38 Raveon Technologies Corp.
The RV-M7 GX can output this message when it receives a position report from
other RV-M7 GX transponders. A plotter or display connected to it that
supports the TLL message, should put an icon on its screen at the location
specified by the RV-M7. The icon name is the MYID of the RV-M7 that
transmitted its position over the air.
$GPWPL NMEA WayPoint List. Output 3 This message is commonly used to share
waypoint locations among GPS units. The RV-M7 GX can output this message
when it receives a position report from other RV-M7 GX transponders. A GPS
connected to it, should put a waypoint on its screen, and in its database, at the
location specified by the RV-M7.
$QVPOS QVPOS message format. Output 6 Used when the system requires this
QVPOS format..
$PMGNWPL Proprietary WLP message format. Output 7 Used when the system
requires this Magellan format.
$GPRMC NMEA GPS Position Fix Data. Output 11 This message looks like local
NMEA data, but is actually the position information from the remote device. It
has no ID field, so it is useful for tracking only one device
$GPGGA NMEA GPS Position Fix Data. Output 12 This message looks like local
NMEA data, but is actually the position information from the remote device. It
has no ID field, so it is useful for tracking only one device
$GPGGA & VTG NMEA GPS Position Fix Data. Output 14 This message looks like local
NMEA data, but is actually the position information from the remote device.
It has no ID field, so it is useful for tracking only one device.

Security Key
The security KEY programmed into every RV-M7 GX transponder ensures that
only RV-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 security code may be from 2 to 16 characters long. The longer the code, the
more secure it is and the less likely anyone could guess what it is. It is up to the
user to select and set this code. If the RV-M7 GX is not used in a system where
security and privacy are a concern, then it is OK to leave the factory-set code.
If it is important that the RV-M7 GX transmissions and system be secure, Raveon
suggest you program the KEY to be a random sequence of letters and numbers at
least 8 digits long.
When you program your own security code into your RV-M7 GX transponders,
write it down in a secure place. This parameter cannot be read out of the RV-M7
GX. If you forget what it is set to, you will have to reset all the security codes in all
of your RV-M7 GX Transponders.
Use the KEYPHRASE command to set the key phrase. For example, to set the
key phrase to Jkl53hhp type:
