Introduction
The TView+ Management Suite software provides a facility to perform Global firmware updates to every Q data radio within a network
over the RF channel. The Global firmware update facility uses two techniques to limit the impact on user data. For instructions on
installing TView+ Management Suite, refer to the TView Diagnostics User Manual.
1. Data rate-limiting which trickles the data onto the RF channel at 5% of the channel capacity.
2. Differential firmware packs (patch files) dramatically reduce the size of the file needed to be sent over the RF channel.
The combination of these two features allows seamless operation of SCADA traffic while the update is in progress.
The firmware upgrading tool is rate-limited to minimise impact on user data. The uploading process will take some time. Allow
up to 24 hours to complete.
Minimum Programmer Requirements
TView+ Programming software Version 3.25.0 (Build 19) onwards.
(It is recommended to upgrade to the latest version of TView+ Programming software).
Connection
Ethernet connection between the PC and the ETH port of the entry point radio. This tool distributes firmware to the
broadcast address of a subnet. If network routers/layer 3 switches/Firewalls or MAC layer filters are located on the Ethernet
connection between the PC and the entry point radio, ensure that broadcast packets are not being blocked/prevented to
allow the tool to work.
Global Firmware Updating
Part J – Firmware Updating and Maintenance
IP Routing Mode
When targeting the network address of the radio network while in IP routing mode, the radio WAN subnet is used.
As the entry point radio is operating as an IP router, a configuration to allow broadcast packets to pass is required.
Within Setup -> IP Routing -> Advanced, enable the parameter ‘Directed Broadcast’. This will allow directed broadcasts
between LAN/WAN.
Repeating Broadcast Messages
Within an IP Routing mode radio topology which includes a repeater, a configuration to repeat broadcast messages is required.
Within Setup -> IP Routing -> Advanced, enable the parameter ‘Forward Broadcast’. This will allow forwarding of broadcasts
received on the WAN back on to the WAN.
Ethernet Filtering
As the global firmware upgrade tool sends broadcast packets as a means of reaching each remote radio, ensure that Ethernet
filtering is not enabled within the entry point radio, which would prevent the firmware upgrade broadcasts from being sent on to
the radio channel.
