DL
Destination Address Low
. The lower 32 bits of the 64-bit
destination address. When combined with DH, DL defines the
destination address used for transmission of transparent
data in either serial mode or IP socket mode.

Example #1: Setting TO to 0x80 would cause all transmissions
to be sent using repeater mode.
Example #2: Setting TO to 0x41 would cause all transmissions

accepts only printable ASCII data In AT Command Mode, the
string can not start with a space. A carriage return or comma
ends the command. Command will automatically end when
maximum bytes for the string have been entered. This string

NT
Node Discover Timeout
. The amount of time a node will
spend discovering other nodes when ND or DN is issued. This
value is used to randomize the responses to alleviate network
congestion. The N? command can be used to determine the
maximum response time a Node Discover will need based on
NT and network propagation time.
