DNT90 Integration Guide - 05/10/12
ParentNwkID - this parameter specifies the parent (BaseModeNetID) that a child radio is allowed to join.
The valid range of this parameter is 0 to 63 (0x00 to 0x3F), plus 255 (0xFF). Setting the ParentNwkID to
255 allows connection to any parent. This parameter is applicable only to remotes and routers. Also see
the discussion of AltParentNwkID below.
Security Key - this 16-byte parameter sets the 128-bit AES encryption key. To protect the key, it is a write-
only parameter for the user. It always reads back as 0x2A.
SleepModeEn - this parameter enables/disables sleep mode (remotes only). Sleep mode is used in con-
junction with the automatic I/O reporting feature to wake up a remote on specific triggers. The default val-
ue for this parameter is 0 (off). Setting this parameter to 1 invokes sleep mode immediately. Setting this
parameter to 2 invokes sleep mode following reset, allowing this and other parameter updates to be
stored before sleep mode is invoked.
WakeResponseTime - this parameter set how long sleep is deferred in a DNT90 remote configured for
sleep mode after:

WakeResponseTime - this parameter set how long sleep is deferred in a DNT90 remote configured for
sleep mode after:
link acquisition
receiving an ACK from the device’s parent
receiving a packet that requires processing by the device
after receiving a protocol packet from the device’s local host.
receiving an ACK from the device’s parent
receiving a packet that requires processing by the device
after receiving a protocol packet from the device’s local host.
WakeLinkTimeout - this parameter sets the maximum length of time that a remote in sleep mode will
spend trying to acquire a link to its parent before going back to sleep, from a minimum of 1 to 255 se-
conds in 1 second steps. If this value is set to 0, the remote will stay awake and continue trying to link to
its base indefinitely.
AltParentNwkID - this parameter specifies an alternate parent (BaseModeNetID) that a child radio is
allowed to join. This parameter is used to provide more robust message routing when setting the Parent-
NwkID to its 0xFF wildcard value is not appropriate. The valid range of this parameter is 0x00 to 0x3F,
plus 0xFF. Rather than specifying wildcard operation, setting the AltParentNwkID to 0xFF disables the
selection of an alternate parent. This parameter is applicable only to remotes and routers.
TxPower - this parameter sets the transmit power level (default is 0x01):

conds in 1 second steps. If this value is set to 0, the remote will stay awake and continue trying to link to

TxPower - this parameter sets the transmit power level (default is 0x01):
0x00 = +16 dBm or 40 mW
0x01 = +22 dBm or 158 mW
UserTag - this parameter is a user definable field intended for use as a location description or other iden-
tifying tag such as a “friendly name”.
RmtTransDestAddr - this parameter holds the default destination for transparent mode data packets and
event packets. This parameter defaults to the base station’s address (0x000000) except on a base sta-
tion, where at startup it will be changed to the broadcast address (0xFFFFFF) if the firmware detects that
it is set to 0x000000. Note - if a module’s configuration is changed from a base to a remote or router, this
parameter must be set back to 0x000000 or the module will send broadcast packets in transparent mode
or for event packets.
Store&ForwardEn - setting this parameter to 0x01 enables store-and-forward system operation. Store-
and-forward operation is disabled by default.
BaseModeNetID - applicable to the base and routers only, this parameter specifies the network ID of a
device’s own network when acting as parent. A child is allowed to join a network when its ParentNwkID
