DNT24 Integration Guide - 10/19/11
3. Select the frequency band of operation by setting the
FrequencyBand
parameter in Bank 1 of the
base radio as desired (the default is Band 0).
4. Set the transmitter power level as needed in all radios by setting the
TxPower
parameter in
Bank 0 (the default is 63 mW).
5. Configure the system ID in all radios by setting the
SystemID
parameter in Bank 0 (the default is
OK if there is no chance of overlapping systems).
6. Load the parent network ID in all remotes in the
ParentNetworkID
parameter in Bank 0 as needed
(wildcard default is OK for point-to-point and point-to-multipoint systems).
7. Set the
BaseModeNetID
parameter in the base to match the
ParentNetworkID
parameter in the
remotes if the default
BaseModeNetID
is not used in the base and the wildcard default
Parent-
NetworkID
is not used in the remotes.
8. For a point-to-multipoint system where DNT24 MAC addressing will be used, set the
Protocol-
Mode
parameter in Bank 4 of the base to 0x01. Set the protocol mode as needed in the base and
remote of a point-to-point system, and as needed in the remotes in a point-to-multipoint system. If
SPI slave mode will be used, protocol mode must be enabled in all system radios. Note that if the
application data includes addressing information for individual remote hosts, the DNT24 broad-
cast mode can be used instead of the DNT24 protocol mode.
9. If using transparent serial mode in the system:
a. Set the remote transparent destination address in the
RmtTransDestAddr
parameter,
Bank 0, in each remote if the destination is not the base (the base address is the default
destination).
b. Set the transparent point-to-point mode to select either the
RmtTransDestAddr
address
(default) or the address of the originator of the last received message as the remote des-
tination address. The parameter that controls this destination address is the
Trans-
PtToPtMode
in Bank 4. Set in all remotes as needed.
c. Set the timeout for transmission of transparent data in the remotes as needed. The pa-
rameter that controls the timeout is the
TxTimeout
in Bank 4 (the default is to send as
soon as possible).
d. Set the minimum message length for transmission of transparent data in the remotes as
needed. The parameter that controls the length is the
MinPacketLength
in Bank 4 (the
default is one byte).
10. Refer to Section 4.6 below which discusses how to coordinate the values of the following four
parameters:
a. Set the maximum number of messages that can be sent in a hop on each system radio.
The parameter that controls this number is
MsgsPerHop
in Bank 4. The default is 8 mes-
sages.
b. Load the required base slot size into the
BaseSlotSize
parameter, Bank 1, in the base.
The default is 40 bytes.
