We have three different digital, roadside signs in use in the district.
Lower Elementary: 10.1.0.101
Junior High:
The junior high has the most issues. It's connected via ethernet cable over an out of spec distance through conduit that is prone to water intrusion. The most reliable way to make updates is to remove the computer from the sign and bring it inside to be connected directly to the wired network.
High School: 10.1.0.100
