PURPOSE:To rapidly, simply, and effectively change over an interface by selecting and connecting the interface only by connecting an external cable without changing over a strap or a dip switch or the like inside and outside the device. CONSTITUTION:The first receiver 12 receives data from the first interface 21 and the second receiver 13 received the data from the second interface 22. These interfaces 21, 22 are connected to an input and output connector 11 by the external cables 23, 27 having connectors disposed at both ends. The external cable 23 capable of connecting the first interface 21 to the input and output connector 11 is constituted of the connector 24 connected to the first interface 21, a cable part 25 and the connector 26 connected to the input and output connector 11. The external cable 27 capable of connecting the second interface 22 to the input and output connector 11 is constituted of the connector 28 connected to the second interface 22, a cable part 29 and the connector 30 connected to the input and output connector 11. |
