F.1 N2 Specifications and Configuration

The bypasses can be monitored and controlled by a controller on a Metasys N2 network (N2) using RS-485 technology. The

bypass act as slaves on the N2 network.

Up to 255 bypasses can communicate on a single N2 network. If more bypasses or N2 devices are required, another N2 network

is required.

The N2 node address is configurable by a parameter in the bypass. This defines the physical address of the bypass on the N2

network.

Once the addressing is set, a controller can initiate communication to the bypass. The bypass will perform the specified function

and then send a response back to the controller.
