249
DO (Device Options)
Sets or displays the device options.
Bit field:
Bit Description
0
Reserved
1
Reserved for Smart Energy devices.
2
0/1 = First or Best Join. First join means the device joins the network through the first
acceptable Beacon response it receives. Best join means the device joins the network through
the strongest Beacon response it receives after searching all search mask channels.
3
Disable NULL transport key (coordinator only).
4
Disable Tx packet extended timeout.
5
Disable ACK for end device I/O sampling.
6
Enable high ram concentrator.
7
Enable
NW
to find new network before leaving the network.
Parameter range
0x00 - 0xFF
Default
0x00
%V (Voltage Supply Monitoring)
Reads the voltage on the Vcc pin in mV.
Parameter range
-0x - 0xFFFF [read only]
Default
N/A
V+ (Voltage Supply Monitoring)
Set the voltage supply threshold with the
V+
command. If the measured supply voltage falls below or
equal to this threshold, the supply voltage appends to the I/O sample set, and sets bit 7 of the Analog
Channel Mask. Set
V+
to
0
by default (do not include the supply voltage). The units of this command
are mV. For example, to include a measurement of the supply voltage when it falls below 2.7 V, set
V+
to
2700
=
0xA8A
.
Parameter range
