Abstract

PURPOSE:To enable the transmission and reception for sure data between a main device and terminals without complicated check circuit, by providing two memory circuits with a data terminal device. CONSTITUTION:When data set keys DT1-DTn are operated, the set data are temporarily stored in a set data temporary memory section MS, and the memory content is displayed with set data lamps SL1-SLn, and the memory content is transmitted from a data transmission section SND to data master device B through the operation of data transmission keys STK. After the registration at a data master device B, when registration data is retransmitted to a data terminal device A, a data reception section REC receives this data and stores it. The memory content is displayed on registration data lamps DL1-DLn and DL1'-DLn'. Data check is made by comparing the set data lamps SL- and the registration data lamps DL-.
