CMG-EAM (Platinum Firmware)
4 Firmware Upgrades
Platinum firmware is regularly updated to provide extra features,
improve performance and, occasionally, to correct errors. The upgrade
process is fast, simple and can be carried out remotely using either the
web or command-line interface.
The upgrade process makes use of the rsync protocol which uses an
elegant and efficient algorithm to, effectively, transfer only the
differences between revisions; even within individual files. This
significantly reduces the time required, compared to traditional
upgrade methods.
