When a certain sub-module 20b is newly mounted in an arbitrary slot, the setting line (l1, l2, l3, l4) connected to a high potential voltage source or ground is set as shown in FIG. 2 in step S1. Analog-digital voltage signals indicating the unique information of the corresponding slot and the unique information given to the sub-module 20b mounted in the corresponding slot through the setting conductor part connected to the lines l1, l2, l3, and l4 are not shown. It is converted to a digital signal through a converter and transmitted to the control unit 20b3 of the sub module 20b.

Here, the operation of receiving the voltage signal representing the unique information will be described in more detail with reference to FIG. 2.

First, in the case of slot 1 shown in FIG. 2 (a), all of the setting lines l1, l2, l3, and l4 are connected to the ground (GROUND, 0 voltage), and all of the four setting conductor portions of slot 1 are all zero. Voltage is applied.

Therefore, the unshown analog-to-digital converter built into the sub-module 20b mounted in the slot 1 can convert four zero voltage inputs into digital signals of 0000 and transfer them to the control unit 20b3 of the sub-module 20b. have.

Therefore, the control unit 20b3 of the corresponding sub-module 20b reads 0000 converted into a digital signal as its own information.

In the case of slot 2 shown in FIG. 2 (b), all three setting lines (l1, l2, l3) among the setting lines (l1, l2, l3, l4) are connected to ground (zero voltage) and the other one The set line 14 is connected to a high potential voltage source of + 5V, for example, and three zero voltage signals and one + 5V high potential voltage signal are applied to the four set conductor portions of slot 2.
