The installation is on a remote island and I can't physically access it
for now. The server since about two months is a Raspberry Pi B+
connected to a wired network. For reliability reasons I have two DS9490s
connected with a USB-hub powered by a 2 A supply. The Pi uses a separate
1 A supply. I use 0,5 mm^2 twisted pair telephone wires and soldered
connections. The most important sensor, green trace, is connected with a
1,5 m cable to one of the adapters. The other two are connected to the
other adapter with 3 and 10 m cables. The sensors use parasitic power.

Manually upgrade your production database.
When you want reliability, choose Perforce
Perforce version control. Predictably reliable.
