6.9 Connecting Green Class Net Meters to the USB 

Key Using RS485

The USB Key plugs into the PC’s USB port and provides a termination point for the 

RS485 wiring from the meters. Up to 52 meters can be “Daisy chained” with up to 4000 

feet total RS485 wiring. The USB Key is labeled for “plus (+)”, “minus (-)“, and ground 

and the wiring must match the same positions on the meters. If more than 52 meters 

are to be monitored, additional USB Keys can be utilized to connect them to the PC.
