PURPOSE:To eliminate the output of the false data and to absorb the noise to generate at the time of inserting and removing the hot-line by providing a pair of the feeding connectors for inserting and removing the hot-line and providing the electric power source filter at the data bus side. CONSTITUTION:A terminal adapter 31 is provided with a slot S3 for actual fitting to a data bus 6 and a feeding connector for inserting and removing the hot-line. To this connector 15, the lines of the electric power sources + five V and zero V supplied to the terminal adapter 31 from the data bus 6, and the lines to prohibit gate circuits 111-11n are connected. A hot-line inserting/removing feeding connector 16, which can be freely connected by 1:1 with the connector 15, is provided, and a connector 16 is connected to the electric power source line of the data bus 6 and the line is input-connected which prohibits the electric power source + five V and zero V and gate circuits 111-11n. Thus, false data are not outputted. The noise to occur at the time of inserting and removing the hot-line is absorbed by an electric power source filter 18. |
