Security Key
The security KEY programmed into every M7 GX transponder ensures
that only 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.
When you program your own security code into your M7 GX
transponders, write it down in a secure place. This parameter cannot be
read out of the M7 GX. Use the KEYPHRASE command to set the key
phrase. For example, to set the key phrase to Jkl53hhp type:
KEYPHRASE Jkl53hhp <enter>
Addressing Basics
Each M7 GX has an MYID programmed into it, and is represented as a 4
digit number. M7 GX IDs may be any number between 0001 and 9999.
The MYID is programmed with the ATMY 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 default Address Mask is F000, which means the M7 GX will receive
a transmission from any other M7 as long as the fist digit matches, in this
case, is a 0.
Make sure you set the MYID of each M7 GX in your system to a different
number.
For example, to set the MYID of your M7 to 17, enter:
MYID 17 <enter>
To set your M7 to send its position and status data to M7 number 1,
enter:
ATDT 1 <enter>
To set your address mask to receive all messages from units with IDs 1-
999, and exclude 1000-9999, enter:
Time Slots
For optimum efficiency in a M7 GX system, begin sequentially numbering
the MYID of the M7 GX transponders at ID 0001. The second M7 should
be ID 0002, and so on.
The M7 GX transponders have internal clocks with 20 ticks-per-second.
They can measure time and initiate transmissions 20 times every second
(every 50mS). The TDMA time slot is configured to be some number of
these ticks. The factory default allocation is 4-ticks for one time-slot. So
