NC (Number of Remaining Children)
Read the number of remaining end device children that can join the device. If NC returns 0, the device
is at capacity and cannot allow any more end device children to join.
Parameter range
0 - MAX_CHILDREN (maximum varies)
Default
N/A
SH (Serial Number High)
Displays the upper 32 bits of the unique IEEE 64-bit extended address assigned to the XBee in the
factory.
The 64-bit source address is always enabled. This value is read-only and it never changes.
Parameter range
0 - 0xFFFFFFFF [read-only]
Default
Set in the factory
SL (Serial Number Low)
Displays the lower 32 bits of the unique IEEE 64-bit RF extended address assigned to the XBee in the
factory.
The 64-bit source address is always enabled. This value is read-only and it never changes.
Parameter range
0 - 0xFFFFFFFF [read-only]
Default
Set in the factory
NI (Node Identifier)
Stores the node identifier string for a device, which is a user-defined name or description of the
device. This can be up to 20 ASCII characters.
n XCTU prevents you from exceeding the string limit of 20 characters for this command. If you
are using another software application to send the string, you can enter longer strings, but the
software on the device returns an error.
Use the ND (Network Discovery) command with this string as an argument to easily identify devices
on the network.
The DN command also uses this identifier.
Parameter range
A string of case-sensitive ASCII printable characters from 0 to 20 bytes in length. The string cannot
start with the space character. A carriage return or a comma automatically ends the command.
