Abstract

PURPOSE:To obtain the information of terminal devices not through other master devices, by enabling to directly connect one transmission system master device with the terminal device on other transmission system, in one transmission system consisting of a master device and a plurality of terminal devices and in another transmission system having the similar constitution. CONSTITUTION:In a tranmsission system A consisting of one set of master device A and terminal devices TCA4-7 and in another transmission system B consisting of one set of master device B and terminal devices TCB4-7, when the master device A is connected to the terminal devices TCB4-7, an a-contact of a relay R1 is open by the control of a switching use terminal device TCQ1 and switched into a b-contact. Thus, the terminal devices TCB4-7 of the transmission system B are detached from the master device B and connected to the master device A.
