House code setting method and power line carrier communication system
First Claim
1. A house code setting method for setting a house code into a plurality of terminals to prevent interference between a system to which the terminals belong and another system, the terminals being connected by a power line and exchanging information through the power line and to which intrinsic terminal identifiers are respectively given, the house code setting method characterized in that on the basis of a terminal identifier given to a master terminal selected from the respective terminals belonging to the same system, the house code is generated as a common code in the same system, and is set into the respective terminals.

Abstract
There are provided a plurality of terminals (10, 20, 30) which are connected by a power line (1) and exchange information through the power line (1) and to which intrinsic terminal identifiers are respectively given, and the feature is that each of the terminals (10, 20, 30) holds a house code to prevent interference between another system and its own system, and the house code is generated as a code common to the same system on the basis of the terminal identifier given to a master terminal selected from the respective terminals (10, 20, 30) belonging to the same system.
