Interconnection of the TC700 and NS950 systems using a serial channel with the RS-485 interface is shown in Fig.1. The connection assumes two systems and thus the bus terminator is connected on both sides. If there are several systems on the bus, the terminator is only connected at the endpoint systems on the bus.
