Hi Total-Pat-Testing
Unfortunately I beleive you cannot download the firmware, Im pretty sure it has to go back to Metrel in order for them to do the upgrade.
I am not sure at what revision of the firmware Metrel added the extra field. Are you sure you don't already have it?
If not, Metrel's UK technical support department seem very good, Im sure they they will be able to tell you at which point they introduced the extra field and how to get your firmware updated if you want to start using the extra field.
Regards, Richard.
