UMAC Experts, do you know where I can get those files? (For Delta Tau UMAC for boot and firmware)

PETHUSB307FX2.zip
FWBootFx2.zip

It is described at Delta Tau's forums but download been disabled. Sent support request to omron but no update yet. Wonder if anyone here have that handy to share or know where to download it?

How to reload the USB & Ethernet firmware and bootstrap

Thanks and regards,
Daniel
