DNT90 Integration Guide - 05/10/12 
MacAddress - this parameter holds the radio's unique 24-bit MAC address. 
 
CurrNwkID - this parameter holds the ID of the network the radio is currently assigned to or connected to. 
A value of 255 (0xFF) means the radio has powered up and is scanning for a network but has not yet 
joined one. 
 
CurrFreqBand - this parameter holds the frequency band of the network that the radio is currently as-
signed to or connected to. A value of 0xFF means the radio has powered up and is scanning for a net-
work but has not yet joined one. 
 
LinkStatus - this parameter holds the link status of a router or remote: 
 
 
0x00  =  idle 
 
0x01  =  lost link 
 
0x02  =  acquiring link 
 
0x03  =  collecting parameters from the base 
 
0x04  =  registering 
 
0x05  =  registered 
 
RemoteSlotSize - this parameter holds the current remote slot size, defined as the maximum number of 
message bytes a remote can send on a single hop.  The RemoteSlotSize is calculated by each radio in a 
system based on the values of the HopDuration, BaseSlotSize, and NumSlots parameters. 
 
SlotNumber - this parameter holds the current slot number assigned to a router or remote. 
 
HarwareVersion - this parameter holds an identifier indicating the hardware revision (ASCII character). A 
value of 0x43 is defined for the DNT90 Revision C hardware. 
 
FirmwareVersion - this parameter holds the firmware version of the radio in 2-digit BCD format. 
 
FirmwareBuildNum - this parameter holds the firmware build number, in binary format. 
 
FirmwareBuildDate - this parameter holds the date of firmware build in MM/DD/YY format. 
 
FirmwareBuildTime - this parameter holds the time of the firmware build in HH:MM:SS format. 
 
RssiIdle - this 2’s compliment parameter holds the last RSSI measurement in dBm made during a time 
when the RF channel was idle. This parameter is useful for detecting interferers. 
 
RssiLast - this 2’s compliment parameter holds the last RSSI measurement in dBm made during the re-
ceipt of an RF packet with a valid CRC. This parameter is useful for network commissioning/diagnostics. 
 
AvgBeaconPower - this 2’s compliment parameter holds the alpha-filtered beacon power (dBm) received 
from a device’s parent, where alpha = 0.0625. 
 
ParentMacAddress - this parameter holds the MAC address of a DNT90’s parent. 
 
ModelNumber - this parameter specifies the DNT model, in this case a DNT90.
