The Utility icon on my DHO804 had an indicator on it this morning. (The scope is hooked up to wifi.) When I went into the Utility menu, it indicated that a firmware update was available. I clicked on an update button, and it installed version 01.01.02. It rebooted, and I validated that the new version was installed. The build date, per Utility->About, is 2023/11/09 17:35:40.
On the one hand I am pleased that the network update actually works (and that the "Utility/Update" menu entry is not just a misdirection for all who actually want to update via USB).
On the other hand, it makes me a bit nervous that oscilloscopes now also "phone home" to the manufacturer. That opens up new possibilities to detect or disable hacked licenses, if Rigol so desires. I think I will configure my firewall appropriately before connecting my new DHO1xx4 to the home network, and am happy to take the USB detour for firmware updates...
Phone home? A device made in and coded in china, gonna phone home?
It can try, but it won't get far on my net.
All the stuff not allowed to get past the local subnet is in 10 space with no gateway and no DNS, running on either it's own wifi AP or cat5 to small switch.
Other "IoT" stuff that I allow to web (tv, AVR, cameras), connects wifi to a dmz zone on it's own 192.168/24 space.
And my normal stuff (small # of items) connect to LAN side of a firewall device in it's own 192.168/24 space.
No traffic can cross between the zones.
