ID Addressing Basics
ID addressing is used to differentiate one RV-M7 Transponder from another. Each
must have a unique number programmed into them, so that when a position report
is received, the ATLAS PL that sent the message can be identified. This is called
the MYID of the unit that sent the message.
Each ATLAS PL has a MYID programmed into it, and is represented as a 4 digit
decimal number. ATLAS PL 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 ATLAS PL modem is 0001, and 0001 is also the
default for the Destination ID also. The ID of your particular ATLAS PL 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.
The default Address Mask is F000, which means the ATLAS PL will receive a
transmission from any other RV-M7 as long as the fist digit matches, in this case, is
a 0.
Make sure you set the MYID of each ATLAS PL in your system to a different
number.
For example, to set the ID of your ATLAS PL to 17, enter:
MYID 17 <enter>
To set your RV-M7 to send its position and status data to RV-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
ATMK F000 <enter>
Time Slots
The ATLAS PL uses a transmission scheme popular in mobile-telephones called
TDMA (Time Division Multiple Access). Each ATLAS PL is allocated a time-slot to
use for sending and receiving radio messages.
Refer to Section Error! Reference source not found. for detailed explanation of
the TDMA scheme. The important point to understand is that for optimum
efficiency in a ATLAS PL system, begin sequentially numbering the MYID of the
ATLAS PL transponders at ID 0001. The second RV-M7 should be ID 0002, and
so on.
