CIMPLICITYHardware Configuration Requirements
The N2 Protocol allows one server and up to 255 devices on a common line. In the CIMPLICITY computer, the Johnson Controls N2 Bus Device Communications Enabler is the server.
The N2 bus is RS485 based but uses special biasing to allow 50 nodes without a repeater. The Johnson Controls MMCVT1010 converter is required for adapting the CIMPLICITY computer's RS232 serial port to the N2 bus.
