This adapter allows you to connect your PowerSight to a standard 10/100BaseT network. This allows your PC to communicate locally or remotely to one or more PowerSight meters. Remote tasks include sending data setups, starting and stopping monitoring, checking operation, and receiving data. The adapter plugs onto DB9 end of the PowerSight communications cable and then attaches directly to an Ethernet hub via a standard 10/100BaseT cable. It comes with installation software. You can be up and running in minutes.
