$GPWPL NMEA WayPoint List. Output 3 This message is commonly used to share
waypoint locations among GPS units. The M6G can output this message
when it receives a position report from other M6G transponders. A GPS
connected to it, should put a waypoint on its screen, and in its database, at
the location specified by the M6G.
8.7. Device Addressing
Security Key
The security KEY programmed into every M6G transponder ensures that only
M6G 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 M6G 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 M6G 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 M6G transponders, write it
down in a secure place. This parameter cannot be read out of the M6G. If you
forget what it is set to, you will have to reset all the security codes in all of your
M6G Transponders.
Use the KEYPHRASE command to set the key phrase. For example, to set the
key phrase to Jkl53hhp type:
KEYPHRASE Jkl53hhp <enter>
ID Addressing Basics
ID addressing is used to differentiate one M6G Transponder from another. Each
must have a unique number programmed into them, so that when a position
report is received, the M6G that sent the message can be identified. This is
called the MYID of the unit that sent the message.
Each M6G has a MYID programmed into it, and is represented as a 4 digit
decimal number. M6G IDs may be any number between 0001 and 9999. The
Unit Address is programmed with the MYID 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 factory default MYID in all M6G modem is 0001, and 0001 is also the default
for the Destination ID also. The ID of your particular M6G may have been
configured by your dealer or distributor. If so, it is labeled on the rear of the unit.
If it is not labeled with an ID, the factory default ID is in it.
