Remote SD Reprogramming
OTA Reprogramming Overview
This feature is for reprogramming SD remote radios only. This will not reprogram other
Master Stations on the network.
The DLink “Root” is the central location from which polling originates. Other locations in the
network should be designated as “Nodes” which are the receiving stations. Over-the-air firmware
upgrades should always be initiated from the Root. This ensures that all radios in the network
will be properly updated.
The Master Station broadcasts a series of messages to one or more remote nodes to accomplish
the reprogramming process. The “broadcast” method is used to program the greatest number of
radios in the shortest amount of time; however, the Master Station remains unaware of the num-
ber or success of downstream radios participating in reprogramming.
During reprogramming, the status of the reprogramming will be available on all the radios partic-
ipating in the process. Because the initiator is “broadcast-only” this status can only indicate pro-
gress toward sending out of all of the messages. On the nodes, the progress toward completion of
reception of reprogramming information is indicated.
Receiving stations can automatically reboot to the new image after successful reprogramming.
Alternatively, there is an OTA reboot command that can be broadcast from the Master Station to
all receiving stations. This last option instructs the receivers to reboot to a specific firmware revi-
sion if available, and not already running at that revision.
Reprogramming Parameters:
The setting for over-the-air reprogramming are found under the “Advanced Config” tab on the
web UI.
- Channel Usage – Set to either Intrusive or Passive as desired.
- Passive (Non-intrusive) operation “piggy-backs” reprogramming data onto nor-
mal payload data streams, thus allowing payload data to continue uninterrupted,
but will be slower than intrusive operation. This mode requires payload data to be
sent so that the reprogramming data can be carried. See Table 5-3 for reprogram-
ming times.
- Intrusive operation means that the payload application data will be interrupted
while programming data is sent over the air. This is the fastest method of pro-
