The default Address Mask is F000, which means the
M6G
will receive a
transmission from any other M6G as long as the fist digit matches, in this case, is
a 0.
Make sure you set the
MYID
of each
M6G
in your system to a different number.
For example, to set the ID of your
M6G
to 17, enter:
MYID 17 <enter>
To set your M6G to send its position and status data to M6G 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
ATMK F000 <enter>
Setting A System-Wide Address
If individual addressing is not needed in your system, there are two ways to
ensure it is not used. One way is to set all modems in the system with the same
Unit Address and Destination Address. From the factory, these are both set to
1234, and thus, all modems can communicate with all other modems, using the
address 1234. The advantage of using this system-wide address, is that if there
are other M6G modems on the channel, but in some other system, they probably
will not have the same Unit Address, and thus will not interfere with your system.
To reduce the possibility of data cross-talk, the system implementer may wish to
use a different system-wide address for the Unit Address instead of 1234. There
are over 65,000 addresses available.
The
ATLA
command can be used to set an additional address that the M6G will
listen for.
An alternate way to disable addressing altogether, is set the Address Mask to
0000 (
ATMK
0000 command). This tells the M6G to ignore the address, and
receive every transmission.
Hexadecimal Numbers
For those not familiar with hexadecimal numbers, a hexadecimal digit represents
a 4-bit binary pattern. There are 16 possible values
(0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,and F). These 16 values represent 4 bits of
information, thus 4 hexadecimal digits can represent 16 bits of information. The
hexadecimal numbers represent 4 bit data in the following way:
