Make sure you update to the latest WatchMon firmware, this is a very important procedure.

When firmware and software don't match this can trigger READ ONLY MODE

Caution:  Make sure that the external peripheral systems will be ok when the system restarts. The system will go offline and then re-start, if there are critical contactor devices that must remain energised additional measures must be made by you to prevent the disruption of power. 

Step 1 - Open the program. There are several ways to get to this

Within the WatchMonToolkit application navigate to the Tools Menu, then select the Firmware Updater

Note: other methods listed in addendum below

Step 2 – Select the Device Firmware you would like to update

For example select (i.e. WatchMonPlus - WM5) may already be defaulted if you have a active connection

Step 3 - Verify no active Toolkit sessions are running

the updater will attempt to close all other sessions to ensure a dedicated connection to the USB port for the firmware update.

Once verified the checkbox will be ticked for Task 1

Troubleshooting - Recovery of non-responding device

There are a number of scenarios when this applies, due to when a previous update was interrupted part way through the process.

  • After Factory erase when there is no program is installed on device
  • Device is not responding to USB enquires (various reasons including missing windows USB driver)
  • Device already has a Newer Release than what the firmware installer would install
  • Wrong Target image is different to the responding attempt (i.e. attempting a WM5 firmware onto a MM8)

The other rejection reason that should not be forced unless directed by the Batrium support team.

  • Device has Already been Updated so no action required


You choose to do a Forced firmware update, this is available from Software version 2.15 onwards.

Step 1 - From the Firmware updater click on the COG

Step 2 - Changed Configuration option Forced Override to ON then press OK

3.  Continue with Upgrade process documented above.
