<p>PURPOSE:To attain the effective remote control by connecting both a remote controller and a device to be controlled to a common bus via each circuit network interface and then setting each circuit network interface address with each circuit network interface. CONSTITUTION:Each network station 10 contains a power supply 30, a gate circuit 31 and plural circuit network interfaces 32 (32a-32c). Then VTRs 33 and 34 are connected to the interface 32a; a remote control panel 35 and VTRs 36-38 are connected to the interface 32b; and a remote control panel 39 and an allotting device 40 are connected to the interface 32c, respectively. It is possible to flow the control signal or data to a cable 1 only when the interface 32 holds a token which circulates among devices. Thus the transmission is possible only when each interface 32 holds a circulation token, respectively. In such a way, the connection is possible to the circuit network accurately in good order.</p> |
