Remote Sd Reprogramming - GE MDS Master Station Technical Manual

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 "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 up-
grades 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 par-
ticipating in the process. Because the initiator is "broadcast-only" this status can only indicate
progress toward sending out of all of the messages. On the nodes, the progress toward comple-
tion 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 re-
vision 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.
