Appendix I: Updating Device Firmware
Overview
The firmware that runs the Breakout box hardware and controls the remote
comms may be updated via the RS485 network using the loader engine built into
ICORE. Before explaining how to update the firmware, please note that
ONLY ONE AMPLIFIER/BREAKOUT BOX MAY BE UPDATED AT A TIME – TURN OFF
ALL OTHER CONNECTED UNITS DURING THE UPDATE PROCEDURE!
The other devices on the network don't need to be physically disconnected, just
turned off (NOT STANDBY – OFF!) so that ICORE can determine which model it
has to update and confirm the update has been a success.
Note that units cannot be updated over the audio transport bridge (i.e.
via another Breakout box) and must be directly connected to the local
RS485 network from the computer.
In the majority of cases firmware updates will be performed within ICORE but,
should there be a problem during the update, such as the connection being
broken, the power being lost, or a computer crash, then there is a back-up
method to rescue the situation. See page 39 for details of this if required.
Update Procedure Using
ICORE
Before starting any updates...
SWITCH OFF ALL UNITS ON THE NETWORK (AMPS AND BREAKOUTS) APART
FROM THE ONE TO BE UPDATED!
CLOSE ALL OTHER OPEN PROGRAMS ON YOUR COMPUTER!
Now, in ICORE, select Tools
Preset/Firmware Loader. You must be OFF-LINE
for this choice to be available.
