CurrRF_DataRate
This returns the RF data rate 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.
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:
0 = initializing
1 = unlinked, scanning for network
2 = linked
RemoteSlotSize
This returns the current remote slot size, defined as the maximum possible user data pay-
load size in bytes. In TDMA modes where the slot size is automatically computed, this
value is read-only. In manual TDMA mode and CSMA mode, this value must be set by
the user. This value excludes the message length byte, REMT_STATUS packet, and
checksum and CRC bytes. It indicates the number of bytes available for REMT_DATA
and/or REMT_DATA_EXTs. It does not include the overhead bytes required for these
packets, which must be figured into the slot size budget.
TDMA_NumSlots
In TDMA access modes, this returns the number of slots currently allocated.
TDMA_CurrSlot
This returns the current TDMA slot number. in modes where the slot position is auto-
matically computed. In modes where this number is not applicable, the value is read as
0xFF.
TDMA_SlotStart
This returns the current TDMA slot position. In TDMA modes where the slot position is
automatically computed, this value is read-only.
HardwareVersion
This returns an identifier indicating the type of radio. A value of 0x00 is defined for the
DNT500 Rev A hardware.
FirmwareVersion
This returns the firmware version of the radio in 2-digit BCD format.
