I leave my Maestro at my vacation home and want to know if it will have to be on the same lan as the radio to upgrade to 2.0. I use softether vpn and R PI to connect for operating now but have always brought the Maestro home to perform any software/firmware update. I just plug it into the same switch that my 6700 is plugged into. Will I be able to upgrade the Maestro from the remote location after I upgrade the 6700 or will I have to bring it home?
You can update the Maestro separately from another location. You just select the new software version on the Maestro.
However, you MUST be in front of the radio to press the PTT on the mic or back panel in order to register the radio. This prevents someone from "stealing" control of your radio without your knowledge. This is a ONE TIME event when you first register the radio and you'll never have to do it again unless you change your login information.
The software license is installed in the radio and is associated with the radio, not the clients. If your radio has Version 2 licensed to it, then it can be connected to by any authorized version 2 client. Since the license is in the radio, not in the clients, you can install version 2 clients anywhere. If you attempt to connect to a version 1 radio with a version 2 client, that connection will be refused because the radio is not licensed to run V 2. I'm not sure what will happen if you try the reverse. It may be refused because of software incompatibility. But, you can install multiple versions of the client software on any system, so you can have a V1 client for one radio and a V2 client for another.
When Maestro goes out on the net to look for versions of software to run, it hasn't looked for a radio yet. You could have the latest V1 and V2 codes installed in Maestro then pick the appropriate version for the radio you intend to operate. The V1 radio would need to be in the same LAN (or connected via VPN), but the V2 radio could be anywhere connected via SmartLink.
