This is UCM/ETH01 with Tibbo
You should be able to buy the ETH03 to replace the ETH01
However you will need to upgrade the UCM firmware which is shown as 5.200
Firmware 5.200 requires another UCM to upgrade it using the UCM programming cable

I suggest you buy the ETH03 from your distributor and ask them to help to upgrade the UCM firmware
