Before pairing the next-gen admin with your Douro, we'll need to first upgrade its software.
The following procedure is for Aaeon-based (10" screen) Douro machines. For the 7" Nexus-based Trofa models, follow the article here.
Connect the machine to an Internet source (Ethernet preferred). If not already initialized, press the INIT button on the screen.
On a computer connected to the same network, visit whatismyip.com and note the IP address.
If your machine is currently paired to a prior-generation admin, obtain the machine's fingerprint from within the server by running the command:
This can also be found from your transaction logs.
Relay the output of the above to our support team (firstname.lastname@example.org) who will update your machine to a compatible version.
We will unpair it remotely before updating so it may be subsequently paired to the next-gen admin. Please plan for downtime between update and pairing.
