Command Summary Description
AT Command: ATDT
<Networking> DT Command is used to
set the networking address of a Module.
Modules use three network layers –
Vendor Identification Number (ATID),
Channels (ATHP), and Destination
Addresses (ATDT). DT Command
assigns an address to a module that
enables it to communicate only with
other modules having the same
addresses. All modules that share the
same Destination Address can
communicate freely with each other.
Modules in the same network with a
different Destination Address (than that
of the transmitter) will listen to all
transmissions to stay synchronized, but
will not send any of the data out their
serial ports.
Binary Command: 0x00
Parameter Range:0 – 0xFFFF
Default Parameter Value: 0
