MacAddress
- returns the radio's unique 24-bit MAC address.
CurrNwkAddress
- returns the radio's current network address, if any. Some special values should be
noted. The base always reports 0x00. If a remote does not have a network address, either because lease
mode is not enabled or it has not yet received one, it reports 0xFF.
mode is not enabled or it has not yet received one, it reports 0xFF.
CurrNwkID
- This returns the network ID of the network that the radio is currently assigned to or con-
nected to. A value of 0xFF means the radio is scanning for a network but has not yet joined one.
CurrRF_DataRate
- this returns the RF data rate of the network that the radio is currently assigned to or
connected to. A value of 0xFF means the radio is scanning for a network but has not yet joined one.
CurrFreqBand
- this returns the frequency band of the network that the radio is currently assigned to or
connected to. A value of 0xFF means the radio is scanning for a network but has not yet joined one.
LinkStatus
- this returns the radio's current connection status to the network. The following codes are
defined:

RemoteSlotSize
- returns the current remote slot size, defined as the maximum number of bytes allocated
to user messages and their RF headers. In the three user selectable TDMA modes the slot size is auto-
matically computed, this value is read-only. In the CSMA modes, this value must be set by the user.
matically computed, this value is read-only. In the CSMA modes, this value must be set by the user.
TDMA_NumSlots
- in TDMA access modes, this returns the number of slots currently allocated.
TDMA_CurrSlot
- returns the current TDMA slot number in modes where the slot position is automatically
computed. In modes where this number is not applicable, the value is read as 0xFF.
Hardware Version -
returns an identifier indicating the type of radio. A value of 0x00 is defined for the
DNT500 Rev A hardware.
Firmware Version
- returns the firmware version of the radio in 2-digit BCD format.
FirmwareBuildNum
- returns the firmware build number, in binary format.
Epoch
- returns the current epoch number.
SuperframeCount
- returns the current superframe count. The count increments every 64 hops.
