Scan Duration. Set/Read the scan duration
exponent.
End Device - Duration of Active Scan during
Association.
Coordinator - If ‘ReassignPANID’ option is set on
Coordinator [refer to A2 parameter], SD determines
the length of time the Coordinator will scan
channels to locate existing PANs. If
‘ReassignChannel’ option is set, SD determines how
long the Coordinator will perform an Energy Scan to
determine which channel it will operate on.
‘Scan Time’ is measured as (# of channels to scan] *
(2 ^ SD) * 15.36ms). The number of channels to scan
is set by the SC command. The XBee can scan up to
16 channels (SC = 0xFFFF). The XBee PRO can scan
up to 13 channels (SC = 0x3FFE).
Example: The values below show results for a 13
channel scan:
